Freight broker margin: how to measure it and protect it

For freight brokers · Updated · TruckerPro editorial team

A freight broker's gross margin on a load is the sell rate charged to the shipper minus the buy rate paid to the carrier, usually shown as a percentage of the sell rate. Across the book, margin should be weighted by revenue, not averaged load by load. Margin is protected in two places: before the tender, with a floor by lane, equipment or customer that warns, asks for approval or blocks a load below it, and after the tender, by billing every accessorial you pay and catching rate changes before the carrier is paid.

Key points

Spread, margin and markup

A brokered load has two prices. The sell rate is what the shipper pays the broker. The buy rate is what the broker pays the carrier. Everything else in margin work comes from those two numbers and the charges that get added to each side after the load moves.

The examples on this page use units rather than currency so the arithmetic is the point. Take a load sold at 100 units and bought at 82 units.

MeasureFormulaExample
Spread (gross profit)Sell minus buy100 minus 82 = 18 units
Margin percentSpread divided by sell18 / 100 = 18%
Markup percentSpread divided by buy18 / 82 = about 22%

Margin and markup describe the same load but answer different questions. Margin tells you what share of revenue you keep. Markup tells you how much you added on top of the carrier's price. Confusion between the two causes real mistakes: a rep told to "add 20%" to a carrier quote produces a markup of 20%, which is a margin of about 16.7%, not 20%. Pick one convention for floors, reports and commissions, write it down, and make sure your system computes it the same way everywhere.

The spread is also what 49 CFR 371.3 calls, in most brokered loads, the broker's compensation. Item (a)(4) of the rule requires the record of each transaction to show the compensation the broker received and who paid it, and item (a)(6) the freight charges the broker collected and the date it paid the carrier. Margin is not only a management number; its inputs are part of the federal record for every load.

Margin across the book: weight it by revenue

Per-load margin is easy. Margin for a week, a customer, a lane or a rep is where reports go wrong, because there are two ways to roll it up and they give different answers.

LoadSellBuySpreadMargin
A, short regional100802020%
B, long haul3002703010%
Total4003505012.5%

The simple average of the two load percentages is 15%. The revenue-weighted margin, total spread divided by total sell, is 12.5%. The second number is the one that pays the bills. A simple average lets a handful of small loads at high percentages make a desk look healthier than it is, and it can reward a rep for chasing short loads that add little gross profit.

Three views are worth keeping side by side:

If the brokerage is part of a company that also runs its own trucks, 49 CFR 371.13 requires the brokerage revenues and expenses to be kept segregated from the other business, with common expenses allocated on an equitable basis you can explain. That makes a clean brokered-load margin report a compliance matter as well as a management one.

Accessorials: pass them through or lose them

Linehaul is only part of a load's money. Detention, layover, lumper fees, extra stops, driver assist, tarping and fuel surcharge all appear as accessorial charges, on the carrier side, the shipper side or both. Each accessorial affects margin in one of three ways.

For this reason, report margin both on linehaul alone and on the full load including accessorials. The linehaul number tells you how well the load was priced and bought. The full number tells you what you actually kept.

A charge for something other than arranging transportation, such as a warehousing or handling service the brokerage sells separately, is what 49 CFR 371.2 calls non-brokerage service. Section 371.3(a)(5) requires it to be shown separately in the transaction record, with its compensation and payer, so keep it on its own line rather than folding it into the linehaul.

Margin floors and approvals

Margin is mostly decided before the load is tendered. Once a carrier has accepted at a buy rate, the only levers left are accessorials and disputes. That is why many brokerages set a margin floor that a tender is checked against before it goes out.

A single company-wide floor is a blunt tool. Margins that are normal on one lane are impossible on another, and a strategic customer may justify a thinner margin than a one-off shipper. Floors work better when they can be set by:

Then decide what happens below the floor. Three responses cover most cases:

ResponseWhen to use it
WarnThe margin is thin but the rep may have a reason: a backhaul, a relationship load, a test of a new lane.
Require approvalA manager should see it first, for example a load at or near break-even, or a large shipment.
BlockThe tender would lose money or breaks a hard rule for that customer.

Whatever the response, keep the record: which rule applied, what the margin was, who approved it and when. When a customer's margin slides over a quarter, that history shows whether the cause was pricing, carrier cost or a string of approved exceptions.

Where margin leaks after the tender

A well-priced load can still end up thin. These are the usual places, and the control that catches each.

Every one of these is easier to catch if the load, the customer invoice, the carrier payable and the accessorials are in one system. When they live in separate tools, margin is only known at month end, when it is too late to bill.

Margin and the carrier's right to review

Under 49 CFR 371.3(c), each party to a brokered transaction has the right to review the record of that transaction, and the record includes the broker's compensation and the freight charges collected. In other words, a carrier on the load may ask to see what the shipper paid and what you kept. Brokers should run their margin on the assumption that it can be seen: rate confirmations that match payables, compensation that matches invoices, and no off-system adjustments that make the record and the bank statement disagree. The companion article on broker record keeping under 49 CFR 371.3 covers the full record.

Where TruckerPro fits

TruckerPro's brokerage tools keep the load, the customer invoice and the carrier payable together. Broker Basic covers rate agreements per customer, accessorials, invoicing, carrier payables and claims, and the brokerage dashboard shows gross margin percent. Broker Everything adds margin rules by lane, equipment or customer: every tender is checked against them, and a tender below a rule shows a warning, needs approval or is blocked. Carriers that also broker get the brokerage tools from the Mobile plan up. For how a broker TMS differs from a carrier TMS, see carrier TMS vs broker TMS.

Frequently asked questions

How do you calculate freight broker margin?

Subtract the buy rate paid to the carrier from the sell rate charged to the shipper to get the spread, then divide the spread by the sell rate. A load sold at 100 units and bought at 82 has a spread of 18 and a margin of 18%.

What is the difference between margin and markup?

Margin is the spread divided by the sell rate; markup is the spread divided by the buy rate. A markup of 20% on the carrier cost is a margin of about 16.7% of revenue.

Should broker margin be averaged per load?

No. Weight it by revenue: total spread divided by total sell for the period. A simple average of load percentages gives small, high-percentage loads too much weight.

How do accessorials affect broker margin?

Passed through at cost, they leave the spread unchanged but lower the margin percent. Billed with a margin, they add spread. Paid to the carrier and never billed to the shipper, they come straight out of the spread.

Can a carrier see a broker's margin?

Each party to a brokered transaction has the right to review its record under 49 CFR 371.3(c), and that record includes the broker's compensation and the freight charges collected.
