Voyage charter and time charter may employ the same ship, carry the same cargo and call at the same ports, yet they create fundamentally different commercial positions. The real difference is not simply “freight versus hire”. It is how the contract allocates time, voyage costs, market exposure, operational control and delay risk between owner and charterer.
Voyage Charter vs Time Charter: The Short Answer
In a voyage charter, the charterer buys an agreed transport service: the carriage of cargo from the contractual loading point to the contractual discharge point, normally for freight expressed per tonne or as a lump sum.
In a time charter, the charterer pays hire for the commercial use of the vessel for an agreed period. The owner remains responsible for the ship’s technical management, crew and seaworthiness obligations, while the charterer normally directs the vessel’s commercial employment within the agreed trading limits and bears many voyage expenses such as bunkers and port costs.
That distinction changes almost every important commercial calculation: who carries bunker-price exposure, who loses money during congestion, whether laytime and demurrage are central, whether off-hire can stop the payment clock, and who benefits or loses when the freight market moves.
Voyage Charter vs Time Charter: The Core Difference
The cleanest way to distinguish the two contracts is to ask one question: what exactly is the charterer paying to obtain?
Under a voyage charter, the commercial object is a defined cargo movement. The owner agrees to provide a suitable vessel and perform the agreed voyage in exchange for freight. The charterer does not normally take over the vessel’s wider commercial employment beyond the contractual voyage.
Under a time charter, the commercial object is the vessel’s earning time. The charterer hires the vessel for a period and can employ her on a sequence of lawful voyages within the charterparty’s trading, cargo and geographical limits.
A useful mental model: a voyage charter mainly prices a transport result; a time charter mainly prices vessel time. It is a simplification, not a legal definition, but it explains why the two structures allocate cost and risk so differently.
BIMCO describes GENCON 2022 as a general-purpose voyage charterparty for the services of a ship in exchange for freight. By contrast, NYPE 2015 is the most widely used standard time charterparty in the dry-cargo sector.
How a Voyage Charter Works
In a voyage charter, the owner agrees to carry a specified cargo between agreed ports, berths or port ranges. Freight may be expressed as a rate per metric tonne, as a lump sum, or through another agreed freight mechanism.
The owner generally remains responsible for the vessel, crew, technical operation and navigation. In common market practice, the owner also bears the major voyage expenses — particularly bunkers, port costs and canal dues — unless the charterparty allocates a particular item differently.
This is why the owner’s freight calculation is not simply a market-rate guess. Before fixing, the owner or operator must estimate the commercial cost of performing the voyage:
- Ballast distance to the load port
- Laden distance to the discharge port
- Expected speed and consumption
- Bunker price and fuel grade
- Port disbursements, pilotage and towage
- Canal or transit costs
- Expected waiting and cargo-operation time
- Commissions
- War-risk or route-related costs where applicable
- The vessel’s alternative earning opportunity
The charterer, meanwhile, must provide the contractual cargo and comply with the cargo-operation obligations in the charterparty. A central part of this risk allocation is laytime: the agreed time available for loading and/or discharging. If allowable laytime is exceeded, demurrage may become payable under the agreed terms.
Tide Signal’s laytime and demurrage guide examines this port-time mechanism in detail.
Voyage Charter: Typical Commercial Position
| Area | Typical Position | Commercial Meaning |
|---|---|---|
| Payment | Freight | Usually per tonne or lump sum, subject to fixture terms. |
| Bunkers | Normally owner’s account | Owner carries fuel-price and consumption exposure for the voyage. |
| Port/canal costs | Normally owner’s account | Owner must price expected voyage expenses into the freight. |
| Cargo handling | Clause-dependent | FIO/FIOS/FIOST or liner terms can materially change the cost split. |
| Port-time mechanism | Laytime / demurrage / despatch | Time allowed for cargo work is contractually measured. |
| Commercial employment | Defined voyage | Charterer purchases carriage for the fixture rather than control of a period of vessel employment. |
How a Time Charter Works
Under a time charter, the owner places the vessel at the charterer’s commercial disposal for an agreed period, while retaining possession of the ship through the Master and crew and remaining responsible for technical management.
Hire is normally expressed as a daily rate, even where payment is made at agreed intervals. Hire generally continues while the vessel is on hire. It does not automatically stop because a port is congested, cargo is unavailable or a voyage becomes commercially unattractive.
The time charterer normally directs the vessel’s commercial employment: where she trades, what lawful contractual cargo she carries and how a sequence of voyages is commercially organised, all subject to the charterparty and the Master’s overriding navigational and safety responsibilities.
The charterer also commonly provides and pays for bunkers during the charter period and bears voyage expenses such as port charges and canal dues. The owner continues to carry technical and operating costs such as crew, maintenance, class, insurance and vessel management, subject again to the actual contract.
BIMCO’s time-charter bunker clauses and industry practice reflect this structure. Steamship Mutual also notes that under most time charterparties, the supply of bunkers is normally the charterer’s responsibility, with agreed bunker quantities dealt with on delivery and redelivery.
Time Charter: Typical Commercial Position
| Area | Typical Position | Commercial Meaning |
|---|---|---|
| Payment | Hire | Usually quoted as a daily rate for the charter period. |
| Bunkers | Normally charterer’s account | Charterer is exposed to fuel price, quantity and voyage-consumption economics. |
| Port/canal costs | Normally charterer’s account | Voyage-expense exposure follows the charterer’s employment of the vessel. |
| Technical management | Owner | Owner retains crew, maintenance, class and technical responsibility. |
| Time-loss mechanism | Hire / off-hire | Hire normally runs unless the off-hire clause applies. |
| Commercial employment | Charterer | Charterer selects lawful employment within contractual limits. |

Who Pays What Under Voyage Charter and Time Charter?
This is the question most people ask first — and the question most likely to be answered too simplistically.
Shipping costs can be separated conceptually into two broad groups:
- Vessel operating / technical costs: crew, maintenance, class, stores, insurance and technical management.
- Voyage costs: bunkers, port charges, canal dues, pilotage, towage, certain agency costs and route-specific expenditure.
Under both a normal voyage charter and a normal time charter, the owner remains responsible for the ship’s technical operation. What changes dramatically is the voyage-cost layer.
Public reporting from dry-bulk owner Genco Shipping provides a useful real-world illustration: under time charters, specified voyage costs such as fuel and port charges are typically paid by charterers, while the company bears those expenses when its vessels operate in the spot voyage-charter market.
| Cost | Voyage Charter — Typical | Time Charter — Typical |
|---|---|---|
| Crew wages | Owner | Owner |
| Maintenance / repairs | Owner | Owner |
| Hull / machinery insurance | Owner | Owner |
| Bunkers | Owner | Charterer |
| Port dues | Owner | Charterer |
| Canal dues | Owner | Charterer |
| Cargo handling | Depends on terms such as FIO/FIOS/FIOST/liner terms | Often charterer’s voyage account, but contract governs |
| War-risk extras | Clause-dependent | Clause-dependent |
| Emissions-related costs | Clause/regime-dependent | Clause/regime-dependent; BIMCO has dedicated time-charter clauses |
Commercial Control Is Not Navigational Control
One of the most important professional distinctions is the meaning of “control”.
A time charterer has broad commercial employment rights, but that does not mean the charterer becomes the shipowner, technical manager or navigator of the vessel.
The owner retains the Master and crew. Navigation, seaworthiness, technical management and the safe conduct of the ship remain within the owner’s sphere, subject to the contract and applicable law.
The charterer’s orders relate to employment: nominations, trading patterns, cargoes and ports within the agreed limits. The Master is not required to follow an order simply because it is commercially attractive if it conflicts with safety, legality or the charterparty.
This separation is one of the reasons time chartering works commercially: the charterer can use vessel capacity without taking over the ship’s technical possession in the way a bareboat charterer would.
Laytime, Demurrage and Off-Hire: The Most Important Difference in Delay Risk
The same five-hour delay can have a completely different financial effect depending on the charter structure.
Under a Voyage Charter
Cargo-operation time is normally regulated by the laytime regime. Once a valid Notice of Readiness has been tendered and the contractual conditions for laytime commencement are satisfied, time is counted according to the charterparty.
If the charterer uses more than the allowed laytime, demurrage may become payable at the agreed rate. If cargo operations finish early and the charterparty provides for it, despatch may be due.
This is why documents such as the Notice of Readiness, Statement of Facts and laytime calculation are commercially decisive in voyage chartering.
Under a Time Charter
There is normally no equivalent owner-charterer laytime clock for ordinary port operations. The charterer is already paying for the vessel’s time through hire.
If the vessel waits five days because the charterer’s cargo programme is slow or the port is congested, hire does not simply stop because the delay is expensive.
Steamship Mutual’s guidance on off-hire explains that a time charterer’s obligation is to pay hire continuously unless there is a clear contractual or other recognised entitlement to stop or deduct hire.
Off-hire is therefore not a synonym for “delay”. It is a contractual mechanism that applies when the facts fall within the agreed off-hire wording.
Professional distinction: Voyage charter asks, “Has the charterer exceeded the allowed cargo-operation time?” Time charter asks, “Is the vessel still on hire, or has a contractual off-hire event occurred?” Those are different legal and commercial questions.
The Sub-Charter Mismatch
The situation becomes more sophisticated when a time charterer acts as a disponent owner and voyage-charters the vessel out.
The disponent owner may continue paying daily hire to the head owner while attempting to recover demurrage from the voyage sub-charterer. The two contractual clocks do not necessarily match.
A delay might count as demurrage under the sub-voyage charter while the vessel remains fully on hire under the head time charter. Alternatively, the sub-charter may suspend laytime while the head charter continues charging hire.
This contractual mismatch is one of the most important sources of commercial exposure in an operator’s book.
Worked Example: The Same Cargo Under Two Charter Structures
The following example is deliberately simplified. The figures are illustrative, not market quotations, and the purpose is to show how the risk changes.
Voyage-charter offer: USD 22.00/MT
Time-charter alternative: USD 18,000/day
Estimated TC voyage expenses: USD 300,000 bunkers + USD 120,000 ports + USD 40,000 canal/agency/other = USD 460,000
Option A — Voyage Charter
From the cargo interest’s perspective, the headline transport cost is USD 1.10 million before any charterer-account cargo costs, demurrage or other fixture-specific items.
The attraction is commercial certainty. The owner carries the bunker and voyage-duration exposure that has been priced into the freight, subject to the charterparty.
Option B — Time Charter for 30 Days
On the initial estimate, the time-charter structure appears USD 100,000 cheaper.
But the apparent saving exists only if the vessel performs the employment close to the expected duration and cost.
What If the Voyage Takes 35 Days?
Five additional on-hire days almost eliminate the original cost advantage.
What If It Takes 40 Days?
The time-charter alternative is now more expensive than the voyage-charter freight, even before considering any additional bunker consumption, port expense or other deviation from the original estimate.
Break-Even Time
In this simplified model, if the vessel remains on hire materially beyond about 35.6 days, the voyage-charter offer becomes economically more attractive.
This is the core of the decision. A time charter may offer lower expected cost and greater upside, but the charterer takes more variance. A voyage charter may look more expensive at the fixing stage because the owner has priced voyage risk into the freight.
Tide Signal’s Voyage Margin Calculator can be used for quick indicative freight and voyage-cost scenarios, although any fixture decision requires the actual vessel data and charterparty terms.
Who Carries the Market Risk?
Charter type also changes exposure to the freight market.
Voyage Charter Market Exposure
Once a voyage is fixed, the owner has locked in the agreed freight for that cargo movement. If the spot market rises sharply immediately afterward, the owner may have missed a better fixture. If the market falls, the fixed voyage may suddenly look attractive.
At the same time, the owner carries much of the voyage-cost risk. Higher bunker consumption, a more expensive bunker stem, longer sea passage or unexpected voyage expense can erode the voyage margin.
Time Charter Market Exposure
A time charterer who fixes a vessel at USD 18,000/day and can employ her in a market generating an equivalent USD 30,000/day may create significant trading margin.
If the market falls below the charter-in hire, the same fixed-rate contract becomes a liability.
In that sense, time chartering separates the vessel owner’s technical asset from the charterer’s freight-market view. The owner locks in a stream of hire, while the charterer takes a larger share of the commercial employment risk and opportunity.
Why Bunkers Matter More Under Time Charter
Because the time charterer normally supplies bunkers, fuel prices directly affect the charterer’s voyage economics. Speed instructions, routing, waiting time and consumption performance therefore become P&L variables.
Bunker quantities and values at delivery and redelivery are also commercial issues. Steamship Mutual notes that under most time charterparties bunkers are normally for the charterer’s account during the period, with the contractual delivery/redelivery mechanism determining the transfer and valuation.
Trip Time Charter Is Not the Same as a Voyage Charter
This is one of the most common terminology traps in chartering.
A trip time charter may cover only one trip — for example, delivery in the Atlantic and redelivery in the Far East — but the contract remains a time charter if the vessel is hired on time-charter terms.
The charterer pays hire rather than voyage freight and normally carries time-charter voyage costs such as bunkers and port expenses. Off-hire, speed and consumption, delivery/redelivery and time-charter employment clauses remain commercially important.
The fact that the employment lasts for only one geographical trip does not convert the contract into a voyage charter.
Remember: “One trip” describes the employment. “Voyage charter” and “time charter” describe the contractual risk structure.
GENCON 2022 vs NYPE 2015
GENCON 2022
BIMCO’s GENCON 2022 is a general-purpose voyage charterparty. BIMCO describes GENCON as its flagship voyage charter form and notes that it is widely used in the dry-bulk sector.
Voyage-charter negotiations around a GENCON-style fixture naturally focus on issues such as freight, cargo quantity, laycan, loading/discharging terms, laytime, demurrage, ports, safe access and voyage-specific risk allocation.
NYPE 2015
The NYPE 2015 is the most widely used standard time charterparty in dry cargo, according to BIMCO.
A time-charter negotiation naturally brings different issues to the centre: hire, duration, delivery and redelivery ranges, bunkers on delivery/redelivery, speed and consumption, trading limits, off-hire, employment orders, cargo exclusions and technical performance.
The form name matters, but the rider clauses matter just as much. Modern fixtures are negotiated documents, and amendments can substantially change the default commercial balance.
Modern Chartering: War Risk, EU ETS and Emissions Costs
The classic comparison — owner pays voyage costs under voyage charter, charterer pays them under time charter — remains useful, but modern shipping adds new cost categories that cannot safely be allocated by assumption.
War Risk
Additional war-risk premium, crew bonus, deviation or security costs may be allocated through specific charterparty wording. The answer is not automatically “owner” or “charterer”.
Tide Signal’s War Risk Premiums guide explains how security exposure can move through freight, insurance and charterparty negotiations.
EU ETS and Emissions Allowances
Emissions costs introduce a similar contractual question. BIMCO’s ETS Allowances Clause for Time Charter Parties 2022 is built around the conventional time-charter logic that charterers provide and pay for bunkers and therefore transfer the corresponding allowances to owners under that clause.
That does not mean every emissions cost in every charter automatically follows the same rule. The applicable regulation and the agreed clause must be read together.
Voyage Charter or Time Charter: Which Structure Makes More Sense?
There is no universally superior charter type. The better structure is the one that places the risks with the party that wants — and is able — to manage them.
A Voyage Charter May Be More Suitable When:
- The charterer has one cargo or irregular cargo requirements.
- The main objective is transport from A to B rather than vessel employment.
- The charterer prefers freight certainty over direct bunker and port-cost exposure.
- The charterer does not want to manage continuous vessel employment.
- The risk of uncertain voyage duration is better left with the owner, subject to laytime and other contractual mechanisms.
A Time Charter May Be More Suitable When:
- The charterer has a recurring cargo programme.
- The charterer needs scheduling and trading flexibility over multiple voyages.
- The charterer has the operational capability to manage bunkers, ports, agencies and voyage execution.
- The charterer has a view that future freight earnings will exceed the fixed hire economics.
- Securing vessel capacity for a period is strategically more valuable than fixing cargo by cargo.
Decision Matrix
| Commercial Situation | Often Favors | Reason |
|---|---|---|
| One-off cargo | Voyage charter | Simple purchase of transport capacity for a defined movement. |
| Continuous cargo programme | Time charter | Secures vessel capacity and scheduling flexibility. |
| Charterer wants bunker-price insulation | Voyage charter | Bunker risk is commonly priced by the owner into freight. |
| Charterer expects freight market to rise | Time charter may offer upside | Fixed hire can be monetised against stronger voyage revenues. |
| High uncertainty over port waiting | Depends heavily on terms | Voyage charter uses laytime/demurrage; time charter normally keeps hire running. |
| Charterer lacks an operating desk | Voyage charter | Time charter requires more active employment and cost management. |
Eight Common Mistakes When Comparing Voyage and Time Charters
- Comparing freight with hire directly. USD/MT and USD/day measure different economic objects. Voyage expenses and duration must be normalised before comparison.
- Assuming every port delay is off-hire. Off-hire depends on the actual clause and facts.
- Assuming time-charter commercial control means navigational control. It does not.
- Ignoring cargo-handling terms. FIO, FIOS, FIOST and liner terms can materially change a voyage charter’s cost allocation.
- Ignoring bunker ROB on delivery and redelivery. Quantity and valuation can materially affect a time-charter account.
- Forgetting sub-charter mismatch. A disponent owner can pay hire under one contract while recovering demurrage under another.
- Using the charter label instead of reading the clauses. Rider clauses can shift costs and risk away from market convention.
- Ignoring modern regulatory and security costs. War risk and emissions exposure require specific contractual analysis.
Voyage charter and time charter are not merely two ways of pricing the same transport service. They are two different machines for allocating uncertainty. Voyage charter converts much of the voyage into a freight price and then isolates port-time risk through laytime and demurrage. Time charter leaves more of the voyage economics open: the charterer pays for time, fuel and employment and therefore gains more control — but also carries more variance. The professional question is not “which charter is cheaper?” It is “which party is being paid to carry which risk?”
Frequently Asked Questions
What is the main difference between a voyage charter and a time charter?
A voyage charter pays freight for an agreed cargo movement, while a time charter pays hire for the commercial use of a vessel over an agreed period. The distinction changes the allocation of bunkers, port costs, time risk and commercial control.
Who pays for bunkers under a voyage charter?
Under normal voyage-charter practice, bunkers are usually for the owner’s account and are priced into the voyage economics. The charterparty can alter this allocation, so the fixture terms must always be checked.
Who pays for bunkers under a time charter?
Under most conventional time charterparties, the charterer supplies and pays for bunkers during the charter period. Delivery and redelivery provisions govern quantities, specifications and valuation.
Does demurrage apply to a time charter?
Laytime and demurrage normally regulate cargo-operation delay in a voyage charter. A time charterer generally pays hire while the vessel remains on hire. A time charterer acting as a disponent owner may separately earn or owe demurrage under a voyage sub-charter.
What is off-hire?
Off-hire is a time-charter mechanism under which hire ceases or may be deducted when the factual circumstances fall within the agreed off-hire clause. Delay by itself does not automatically make a vessel off-hire.
Who pays port charges under a time charter?
Voyage-related port charges are normally for the time charterer’s account because they arise from the charterer’s commercial employment of the vessel, although the contract and cause of the expense must always be checked.
Is a trip time charter the same as a voyage charter?
No. A trip time charter may cover a single geographical trip, but if it is concluded on time-charter terms the charterer pays hire and the contractual risk structure remains that of a time charter.
What are GENCON and NYPE?
GENCON 2022 is BIMCO’s general-purpose voyage charterparty. NYPE 2015 is the most widely used standard time charterparty in the dry-cargo sector.
Which is cheaper: voyage charter or time charter?
Neither is inherently cheaper. A voyage-charter freight rate includes risks and costs that a time charterer may pay separately. A meaningful comparison must include hire, voyage duration, bunkers, port and canal costs, cargo handling, commissions, waiting time and contract-specific risks.
Which charter type gives the charterer more control?
A time charter gives the charterer broader commercial control over vessel employment within the agreed limits. The owner and Master retain responsibility for the vessel’s technical management, navigation and safety.
