TL;DR

• TCE converts any charter into a single $/day earnings figure by taking voyage revenue, subtracting voyage expenses, and dividing by round-trip days. It strips out route-specific cost differences so two voyages can be compared like for like.
• Route-level benchmarking, not the raw spot rate, drives chartering decisions. A Worldscale point or $/pmt quote tells you nothing about daily earnings until you net out bunkers, port costs, and ballast days.
• This guide covers three dirty tanker classes (VLCC, Suezmax, and Aframax) benchmarked against Baltic Exchange routes such as TD3C, TD6, and TD7.
• TCE diverges sharply across routes within one class. In Week 14 2026, Suezmax TD23 hit $380k/day while TD20 sat below $200k/day.

What TCE Measures and Why the Formula Matters

Time Charter Equivalent measures a vessel's average daily revenue after voyage costs, expressed in US dollars per day. It normalizes earnings across charter types, routes, and vessel sizes so an owner can compare a voyage fixture directly against a time charter hire quote. The core formula is simple. TCE equals voyage revenue minus voyage expenses, divided by round-trip duration in days (Investopedia).

Each input in that formula carries weight. Voyage revenue comes from gross freight earnings, the freight rate multiplied by cargo tonnage. Voyage expenses cover bunkers, brokerage commission of roughly 1.25% paid by the shipowner, port costs, and canal dues for transits like Suez or the Turkish Straits. Round-trip duration includes both the laden leg and the ballast leg, plus any port waiting time. Lengthen that denominator and the daily figure falls, even when total revenue stays the same (Heisenberg Shipping).

The raw spot rate cannot support a chartering decision because it ignores all of that. A spot rate quoted at $20 per tonne on a 40,000-tonne cargo says nothing about how many days the voyage runs or how much fuel it burns. Two routes can carry the same spot rate and produce wildly different daily earnings once bunker consumption and ballast distance enter the math. Cargo brokers use TCE precisely because it presents opportunities to owners in a standardized $/day format that removes those voyage-specific differences.

Two operational details shape how you read a TCE figure. First, TCE is a non-GAAP measure, so companies report it as a footnote rather than a headline accounting line. Second, speed creates a trade-off the formula exposes directly. Slower sailing cuts fuel cost and raises net freight, but it adds voyage days and dilutes the per-day result. A speed reduction only pays when fuel savings exceed the earnings lost to extra days, which is why owners run at full speed when time charter rates are high.

Calculating TCE: Inputs, Variables, and a Worked Example

A TCE calculation needs six inputs, and a chartering analyst can assemble all of them before a fixture is concluded. Each input feeds the formula in a fixed role, so a structured layout keeps the arithmetic transparent and repeatable.

The formula deducts voyage costs from gross freight, divides by voyage days, and adds back the daily OPEX to express earnings on a comparable hire basis. Written out, TCE ($/day) = (Gross Freight − Brokerage − Voyage Costs) ÷ Voyage Days + OPEX $/day, following Heisenberg Shipping's extended method.

Take a crude tanker carrying 50,000 mt at $17.50 per tonne. Gross freight comes to $875,000, and brokerage at 1.25% removes $10,937.50. Voyage costs covering bunkers, port dues, and canal transit total $273,000, which leaves a voyage cashflow of $591,062.50. Over a 37-day round trip that cashflow equals $15,974.67 per day, and adding $4,000 in daily OPEX brings the result to $19,974.67 per day.

Two variables move that figure more than any other, and both reward testing before you commit to a rate. Bunker price drives the cost side hardest. If higher fuel prices push voyage costs from $273,000 to $323,000, the voyage cashflow drops by $50,000, and the per-day TCE falls by roughly $1,350 over the same 37 days.

Voyage days work in the other direction by diluting the cashflow across a longer base. Hold the cashflow at $591,062.50 and stretch the voyage from 37 days to 42 because of port waiting or a slower ballast leg, and the daily figure drops from $15,974.67 to $14,073.06 before OPEX. The added days also carry an opportunity cost, since each day spent on this voyage is a day unavailable for the next fixture.

Run both sensitivities together before a fixture, and you see how a rate that looks acceptable at posted bunker prices can turn marginal under a fuel spike or a congested discharge port. A single $/day number hides that risk. The inputs behind it do not, which is why the worked calculation matters more than the headline result.

Route-Level TCE Benchmarks: VLCC, Suezmax, and Aframax

The Baltic Exchange publishes daily TCE assessments across 35 clean and dirty tanker routes, and its route taxonomy is the reference frame every chartering desk benchmarks against. Each dirty route carries a fixed vessel size and trade lane, so when you quote a TD3C rate, the counterparty knows you mean a 270,000 dwt VLCC running Middle East Gulf to China. The composite TCE for each vessel class averages a defined set of these routes, which is what lets you compare a single fixture against a published market number.

For VLCCs, the composite averages TD3C (Middle East Gulf to China), TD15 (West Africa to China), and TD22 (US Gulf to China). Suezmax benchmarking centers on TD6 (Black Sea to Mediterranean) and TD20 (West Africa to UK-Continent), with TD23 (Middle East Gulf to Mediterranean) tracking the eastern arbitrage. Aframax coverage spans TD7 (North Sea to Continent), TD8 (Kuwait to Singapore), TD19 (Cross Mediterranean), TD25 (US Gulf to UK-Continent), and TD26 (East Coast Mexico to US Gulf). The size cut-off matters because a 70,000 dwt Aframax on TD26 earns on a different cost base than an 80,000 dwt vessel on TD8.

The reason route-level benchmarking beats a single class average is that TCE diverges sharply within the same vessel class. In Week 14 of 2026, Signal Ocean's market monitor recorded TD23 Suezmax peaking above $380,000/day while TD20 Suezmax softened below $200,000/day at the same moment. Both routes use a roughly 135,000 dwt vessel, yet a Suezmax fixed on the eastern leg earned nearly double a Western Africa fixture. Benchmarking against a blended Suezmax index would have hidden that gap entirely.

Three forces drive the spread. The first is tonne-mile demand, which the tonne-mile index tracks against a baseline of 100. In Week 14, Aframax sat at 120.6 percent and gained week-on-week, Suezmax held at 101.2 percent, and VLCC sank to 55.3 percent, well below the threshold that signals healthy demand. The second is geopolitical rerouting. Strait of Hormuz risk pushed Saudi liftings toward the Yanbu bypass terminal, which recorded 47 VLCC liftings in March 2026 against a January-February average of 11 to 12, and that rerouting carried the AG premium that lifted TD3C and TD23 earnings. The third is supply imbalance. US Gulf Aframax net spot supply collapsed to 2 vessels, a record low, and TD26 surged to roughly $370,000/day as charterers competed for the few ships available.

These three forces also explain why one class can spike while another stalls. VLCC TD3C and TD2 held above their 52-week average of $100,000/day in late March despite falling from earlier highs near $600,000/day, because the Hormuz premium kept Gulf-loading demand firm even as the broad VLCC tonne-mile reading turned weak. On the Atlantic side, TD15 West Africa to China posted a steep monthly decline as the basin moved toward oversupply, with VLCC net spot supply in the region at 20 vessels and a 42 percent net-to-gross ratio flagging surplus tonnage from mid-April. Reading the right route, not the class average, is what tells you which of these regimes your fixture sits inside.

Seasonal Patterns and Structural Rate Drivers

Geopolitical rerouting moves tanker TCE faster and harder than any seasonal pattern. When the Strait of Hormuz faced closure risk in February 2026, TD3C-TCE on the Middle East Gulf to China route surged past $200,000 per day, and earlier highs reached $600,000 per day before settling well above the 52-week average of $100k/day. The mechanism is tonne-mile inflation. Cargo that would have transited Hormuz reroutes through Saudi Arabia's Yanbu terminal, which recorded 47 VLCC liftings in March 2026 against a January to February monthly average of 11 to 12. Longer voyages absorb the same fleet over more sea days, tightening available tonnage and lifting daily earnings.

The tonne-mile index, indexed to 100 as a seven-day moving average, tells you which vessel class is absorbing that demand. In Week 14 2026, VLCC sat at 55.3 percent, far below the 100 percent threshold and signaling demand weakness, while Aframax led at 120.6 percent. When one class diverges this sharply from another, the spread reflects where rerouted barrels actually land rather than a uniform market move. An analyst reading historical charts should treat a class-level index above 100 as the structural backdrop for a rate spike, not its trigger.

Supply-side collapses are the leading indicator that precedes the spike itself. USG Aframax net spot supply fell to 2 vessels in Week 14 2026, a 67 percent week-on-week drop flagged as a record low, and TD26 on the East Coast Mexico to US Gulf route then surged to roughly $370,000 per day. Net spot supply counts the vessels genuinely available to fix in a region. When that number collapses, owners gain pricing power before the rate prints, so watching tonnage availability gives you several days of lead time over the rate index.

Separating seasonal patterns from structural shifts requires multi-year data the live weekly figures cannot provide. A single quarter of high TD3C rates could reflect a winter heating premium or a one-off Hormuz event, and you cannot distinguish them without a five-to-ten-year TCE series for the same route. Build your baseline from at least three full annual cycles per route, then flag any deviation that holds beyond a typical seasonal window as a candidate structural shift driven by fleet ordering, OPEC supply policy, or sustained rerouting.

How to Benchmark Your Fixture Against the Market Using Signal Ocean

Benchmarking a fixture against the market follows four steps, and each one builds on the route taxonomy already established. The goal is to learn whether the rate you fixed sits inside the current market range or far enough outside it to demand an explanation. Signal Ocean supports this because it combines live AIS vessel positions with freight rate intelligence in one platform, so you can read a TCE level alongside the tonnage that actually drives it.

Step 1: Select vessel class and route

Start by matching your voyage to its Baltic benchmark route. A VLCC moving crude from the Middle East Gulf to China maps to TD3C. A Suezmax loading in the Black Sea for the Mediterranean maps to TD6. An Aframax running East Coast Mexico to the US Gulf maps to TD26. The Baltic taxonomy gives you a reference frame that the whole market uses, so your comparison rests on a shared definition rather than a private estimate.

Step 2: Pull the historical TCE series

Pull the historical TCE series for that route and establish where the current rate regime sits. A single day's print tells you little. A 52-week series tells you whether today's level is normal, elevated, or extreme. TD3C-TCE and TD2-TCE held well above their 52-week average of $100k/day in late March 2026, even after dropping from highs near $600k/day seen earlier that month, according to Signal Ocean's Week 14 monitor. Reading that history first stops you from treating a spike as a baseline.

Step 3: Calculate your own fixture TCE

Calculate your fixture's TCE using the standard formula. Take gross freight, subtract brokerage commission, bunker costs, and port and canal dues, then divide by total round-trip days including the ballast leg. Add OPEX per day back if the benchmark you compare against includes it. The result is a single dollars-per-day figure stripped of voyage-specific cost differences, which is exactly what makes it comparable to the published route TCE.

Step 4: Measure the spread

Measure the spread between your fixture TCE and the market route TCE, then size it against recent volatility. A fixture $20k/day below market means one thing in a quiet regime and another when the route has swung by hundreds of thousands of dollars per day inside a month. TD23-TCE peaked above $380k/day in late March 2026 while TD20-TCE softened below $200k/day, so a Suezmax spread of $30k/day reads as noise against the first route and as a real gap against the second.

What the spread signals

A spread tells you whether to accept, renegotiate, or investigate the fixture. A rate within a normal band of the market is acceptable, and you fix with confidence. A rate well below market on a route holding firm is worth renegotiating, because you are leaving earnings on the table that the prevailing supply-demand balance supports. A rate far above or below market is an outlier that needs an explanation before you act. Check whether thin tonnage justifies the premium, as it did when USG Aframax net spot supply collapsed to two vessels, a record low. Check whether geopolitical rerouting is distorting the picture, as the Hormuz reroutings that pushed Yanbu to 47 VLCC liftings in March 2026 did across the AG routes. The spread points you to the question. The positional context inside Signal Ocean answers it.

Signal Ocean vs. Sparta Commodities vs. Xeneta vs. Baltic Exchange: A Direct Comparison

The four platforms most often named in TCE benchmarking discussions solve different problems, and only two of them produce route-level tanker TCE at all. Before you pay for any of them, match the tool to whether you need trading signals, procurement benchmarks, methodology transparency, or fixture benchmarking with vessel positions attached.

Sparta Commodities targets trading desks, not chartering analysts pricing a specific tanker fixture. Its October 2025 restructure into Curves, Knowledge, and Intelligence modules treats freight as one input alongside swaps, physical, and futures pricing, with the Intelligence module outputting combined arb, blend margin, and freight signals (LinkedIn). No published source confirms route-level TCE by vessel class, so Sparta answers "where is the trade" rather than "is my Suezmax fixture above or below TD20."

Xeneta benchmarks ocean and container freight procurement, and no available source confirms crude tanker TCE coverage. Third-party listings describe it as offering transactional spot and contract rate benchmarking across global trade lanes, which serves logistics and procurement teams buying container slots (LinkedIn). If you charter VLCCs, it sits outside your workflow.

The Baltic Exchange is the methodology standard, and its November 2025 TCE earnings calculator turns the composite route assessments into a usable tool. It covers crude and products tankers, displays the constituent income and expense lines, and returns results in $/mt or $/day while letting you test alternative speeds and consumptions by route (Baltic Exchange). Its API serves the published benchmarks, but it carries no AIS vessel data, so you see the route rate without seeing which ships are positioned to take the cargo.

Signal Ocean joins live AIS vessel positions to freight rate intelligence in one platform, which is the combination chartering analysts lack elsewhere. When TD15 West Africa shows 20 net spot vessels against 48 gross supply, the positional context explains why the rate is softening before the benchmark fully reflects it. That tonnage view turns a TCE spread from a number into a decision you can defend.

For fixture benchmarking that accounts for both market rate and available tonnage, Signal Ocean and the Baltic Exchange are the two relevant tools. Choose the Baltic for the published standard and methodology transparency, and choose Signal Ocean when you need the rate read alongside the vessels competing for the same cargo.

Practical Workflow for Chartering Teams: From Data Pull to Decision

Run the same six steps for every fixture decision, and the spread between your number and the market number tells you whether to fix, wait, or renegotiate.

1. Define the voyage parameters. Fix the load and discharge ports, cargo size, vessel class, and an honest estimate of voyage days including the ballast leg. A West Africa to China VLCC voyage and a US Gulf to China VLCC voyage benchmark against different Baltic routes (TD15 versus TD22), so the route you map to determines which market number you compare against.

2. Calculate your own TCE. Apply the formula. Subtract brokerage, bunker costs, port and canal dues, and OPEX from gross freight, then divide by total round-trip days. The bunker estimate carries the most uncertainty, so price it at the speed you actually intend to sail.

3. Pull the market TCE for the route. Retrieve the historical TCE series for the matching Baltic route on Signal Ocean. The current level against the 52-week average establishes the regime. TD3C and TD2 holding above their $100k/day 52-week average in late March 2026 signals a firm market, not a normal one.

4. Assess the spread. Measure how far your fixture TCE sits above or below the market line, and size that gap against recent volatility. A $20k/day gap means little in a route swinging between $200k and $600k/day. The same gap on a route trading flat near $80k/day demands an explanation.

5. Check supply-side signals. Read the tonne-mile index and net spot tonnage for the route before you act. US Gulf Aframax net spot supply collapsing to two vessels, a record low, supports holding a firm rate. VLCC West Africa sitting oversupplied with a 42% net-to-gross ratio from mid-April warns that rates will likely soften, so a spread below market today may correct on its own.

6. Decide to fix, wait, or renegotiate. A spread above market is acceptable when tonnage is thin or the route sits in a spike regime, because the market will likely chase you upward rather than undercut you. A spread above market in a softening, well-supplied route warrants renegotiation, since competing tonnage gives the charterer leverage you do not have. A spread below market on a tightening route is a reason to wait, not to fix at a discount you will regret within the week.

Frequently Asked Questions

What is the difference between TCE and spot rate?

The spot rate is the raw freight price for a single voyage, quoted in Worldscale points, dollars per tonne, or a lump sum. TCE converts that rate into a daily earnings figure net of voyage costs, which makes it directly comparable to time charter hire. Cargo brokers rely on TCE because it strips out voyage-specific cost differences and presents every opportunity in a standardized dollars-per-day format.

How often do Baltic TCE benchmarks update?

The Baltic Exchange publishes daily physical and forward TCE assessments across 35 clean and dirty tanker routes. Signal Ocean tracks these benchmarks alongside live AIS data, so a chartering desk sees current route levels rather than stale weekly figures. Daily cadence matters because tanker rates can move sharply, as VLCC AG routes did in early 2026 when TD3C-TCE surged past $200,000 per day.

Can TCE be negative?

Yes, TCE turns negative when voyage costs exceed gross freight, leaving no revenue to cover daily operations. Long ballast legs, high bunker prices, and weak freight rates can combine to push the figure below zero on a marginal fixture. A negative or near-zero TCE on Signal Ocean signals a voyage that an owner should renegotiate or decline rather than fix.

What voyage costs most affect tanker TCE?

Bunker fuel is the dominant variable cost, and it shifts with both price and the speed an owner chooses to sail. Port costs and canal dues come next, with Suez, Panama, and Turkish Straits transit fees varying sharply by route. Signal Ocean lets you compare TCE across routes so you can see how these route-specific costs reshape daily earnings within the same vessel class.

How does ballast leg length affect TCE?

A longer ballast leg adds voyage days that earn no freight, which dilutes the per-day figure even when laden revenue stays constant. The ballast-leg speed is the owner's or time charterer's decision, so trimming it carefully balances fuel savings against added days. Signal Ocean pairs route TCE with live vessel positions, helping you assess ballast distance to a load port before committing to a fixture.
