A broker commission is a fee that depends on a result: a rate, a flat amount or a scale is applied to a base defined in the agreement, the fee becomes due when a stated event happens (usually the closing of the deal), and it is then paid to the brokerage, which divides it among the people who worked on it. Four things therefore decide what you take home: the formula, the base, the trigger and the split.
Those four things work the same way whether you broker businesses, property, yachts, equipment, freight, insurance or commodities. Most disputes come from one of them being left open: a rate with no defined base, a base with no stated trigger, or a trigger with no payment date.
The sections below take each question in turn and then run one deal through all of them, from the price on the contract to the amount that reaches one broker. The law of commissions differs by country and by state, so where a rule is quoted its jurisdiction is named. Everything here is general information, not legal advice.
Figures from the worked example later in this article. The scale, the shares and the price are illustrative, not market averages.
What is a broker commission, and what does it pay for?
A broker commission is contingent pay for bringing two parties to a completed transaction: the broker is paid because the deal happened, not for the hours spent trying. That contingency is what separates a commission from a retainer, an hourly fee or a salary.
The economic logic is risk transfer. A client who pays on commission pays nothing, or very little, for the deals that never close, so the broker carries the cost of every search, listing, valuation and negotiation that leads nowhere. The rate on the deals that do close has to cover the ones that do not.
A commission is also a contract term, not a law of nature. In most industries no statute fixes the rate. In United States residential property, for example, the National Association of Realtors has stated publicly that it does not set commissions. Where a regulator does intervene, it usually regulates disclosure or fairness, not the number: for securities, FINRA Rule 2121 requires that a commission be fair in light of the circumstances, and its supplementary material says of the well-known 5% benchmark that it "is a guide, not a rule".
Not every broker's pay is called a commission. A freight broker usually earns a margin, the difference between what the shipper pays and what the carrier is paid. An insurance broker usually earns a percentage of the premium, paid by the insurer. A dealer who buys and resells earns a mark-up. Each still has a formula, a base, a trigger and a split.
What are the main ways a broker commission is calculated?
A broker commission is calculated in one of six common ways: a single percentage, a flat fee, a tiered scale applied bracket by bracket, a sliding scale applied to the whole amount, a spread between two prices, or a hybrid of a fixed retainer and a success fee. The method matters as much as the rate, because two agreements quoting the same headline percentage can produce very different fees.
| Method | How the fee is computed | Where you meet it |
|---|---|---|
| Single percentage | One rate times the whole base | Property, yachts, art, equipment |
| Flat fee | A fixed amount, whatever the price | Small deals, leases, limited-service mandates |
| Tiered (marginal) scale | A different rate on each bracket of the base, added up | Business sales, M&A, capital raising |
| Sliding (whole-amount) scale | One rate, chosen by the band the total falls in, on the whole base | Some business sale and volume agreements |
| Spread or margin | Price charged to one side minus price paid to the other | Freight, commodities, dealing desks |
| Retainer plus success fee | A fixed fee during the work, then a contingent fee at closing | M&A, executive search, larger mandates |
A single percentage keeps the broker's interest tied to the price: on an illustrative 5% rate, a $400,000 sale pays $20,000 and a $1,000,000 sale pays $50,000. A flat fee does the opposite. A flat $25,000 is 6.25% of a $400,000 deal and 2.5% of a $1,000,000 deal, and it equals the 5% commission at exactly $500,000. Below that price the flat fee pays the broker more; above it, the percentage does. A client with a high-value, easy-to-sell asset tends to prefer a flat fee, and a broker facing an uncertain price tends to prefer a percentage with a minimum.
Minimums and caps are common additions: a minimum fee protects the broker on a small deal, a cap protects the client on a very large one, and both should be written as amounts next to the rate they modify.
What is the base the commission rate is applied to?
The base is the amount the rate multiplies, and it must be defined in the agreement, because "5% of the sale" can mean the gross contract price, the price net of adjustments, the cash actually received, or the total value of a deal including debt. A rate without a defined base is half an agreement.
The usual candidates, by industry:
- Property and yachts: the gross contract price, before the seller's costs, loan payoff and credits. If the price is reduced after inspection or survey, the agreement should say whether the base follows the reduction (it normally does, since the base is the final price).
- Business sales and M&A: often the total consideration or enterprise value, which can include debt assumed by the buyer, deferred payments, earn-outs, seller financing, consulting agreements and retained property. Each of those items is either in the base or out of it, and the list belongs in the engagement letter.
- Insurance: the premium, usually excluding taxes and policy fees.
- Freight: the broker's margin is itself the difference between two rates, so the base question becomes which accessorial charges (detention, fuel surcharge, lumper fees) pass through and which belong to the margin.
- Equipment and commodities: the invoice value, with the agreement stating whether freight, duties and taxes are inside or outside.
A small example shows the stakes. Take a $900,000 sale at an illustrative 5%, where the seller grants the buyer $60,000 of credits at closing. On the gross price the commission is $45,000. On the price net of credits, $840,000, it is $42,000. The $3,000 difference is exactly 5% of the credits, and nobody decided it unless the agreement did.
Two base questions come up in almost every industry. Non-cash consideration (shares, a note, a trade-in) needs a valuation rule and a date. Contingent consideration, such as an earn-out that may never be paid, needs a rule saying whether the fee is computed on the maximum, on an agreed estimate, or only on what is actually received.
How does a tiered or sliding commission scale work?
A tiered scale applies a different rate to each bracket of the base and adds the results, while a sliding scale picks one rate according to the band the total falls in and applies that rate to the whole amount. The first always pays more as the price rises; the second can pay less on a higher price.
The best-known tiered scale is the Lehman formula, developed by Lehman Brothers in the early 1970s for capital-raising work: 5% of the first $1 million, 4% of the second, 3% of the third, 2% of the fourth and 1% of everything above $4 million. Applied bracket by bracket, a $3,000,000 deal pays $50,000 plus $40,000 plus $30,000, which is $120,000. A widely used variant, the double Lehman, doubles each rate to 10%, 8%, 6%, 4% and 2%. Firms adapt the brackets and rates freely, so ask for the brackets, the rates and the method.
The method is the part people skip. Take an illustrative three-tier scale: 8% up to $1,000,000, 5% from $1,000,001 to $2,000,000, and 3% above $2,000,000. The chart shows the fee it produces at five prices, read each way.
Illustrative scale, not a market rate. Sliding reading: 8% of the whole price up to $1,000,000, 5% of the whole price up to $2,000,000, 3% of the whole price above.
Under the sliding reading, a $3,000,000 sale pays the broker less than a $2,000,000 sale. A whole-amount scale does this at every breakpoint, which puts the broker's interest against the client's exactly where the price crosses a band.
When is a broker commission earned?
A broker commission is earned when the event named in the agreement occurs, and if the agreement names none, the default rule of the governing law decides, which is not the same everywhere. Earned means the right to the fee exists; it does not mean the money has moved.
Three triggers are in common use:
- Introduction of a buyer who is ready, willing and able to buy on the client's terms. Under this trigger the fee can be owed even if the client then declines to sell.
- Signature of a binding contract between the client and the counterparty.
- Completion: the closing, delivery or funding of the transaction.
In United States property law the older default treated the broker's work as done once a ready, willing and able buyer had been produced and accepted. In Ellsworth Dobbs v. Johnson, decided in 1967, New Jersey's highest court moved the line: absent a wrongful act by the seller, the broker earns the commission only when the broker produces such a buyer, the buyer enters a binding contract with the owner, and the buyer completes the transaction by closing title. States differ on which rule they follow, and most listing agreements now state the trigger expressly so the default never has to be argued.
Some jurisdictions require the trigger to be disclosed in advance. In the United Kingdom, section 18 of the Estate Agents Act 1979 requires an estate agent, before the client enters the contract, to give particulars of the circumstances in which the client will become liable to pay and of the amount of the remuneration or the manner in which it will be calculated. If the agent does not, the contract is enforceable only by order of the court, which may reduce or discharge the sum payable.
Whatever the industry, the trigger clause should also deal with the two cases that produce most arguments: a deal that fails because the client withdraws or defaults after the trigger conditions were otherwise met, and a deal that closes after the agreement has ended with a party the broker introduced. The second case is the subject of a tail clause.
When is a broker commission actually paid?
A broker commission is paid on the date and by the method the agreement sets after the fee is earned: most often out of the proceeds at closing, otherwise on invoice within a stated number of days, in instalments that follow a deferred price, or periodically as a client pays premiums or freight bills. Earned and paid are two different dates, and the gap between them is where a broker carries credit risk.
| Payment pattern | When the money moves | What the broker carries meanwhile |
|---|---|---|
| Out of proceeds at closing | Same day as the deal, through the closing or settlement agent | Little: the fee is a line of the settlement |
| On invoice after completion | Days or weeks after, on the terms stated | Collection risk on the client |
| Pro rata with deferred price | Each time the client receives an instalment | The buyer's performance over months or years |
| With each premium or shipment | Recurring, as the underlying payments are made | Cancellation and chargeback of unearned amounts |
Deferred consideration is the main reason an earned fee is paid late. If part of the price is a seller note or an earn-out, the client will resist paying a fee today on money that may arrive in two years or not at all. The usual compromise is to pay the fee on the cash at closing immediately, and the fee on each later payment when that payment is received.
Recurring commissions add the question of reversal. In insurance, a commission is typically a percentage of the premium, and if the policy is cancelled mid-term the insurer returns the unearned premium and recovers the matching commission. On an illustrative 12% commission and a $20,000 annual premium, the commission is $2,400, and a cancellation halfway through the term would leave $1,200 to give back.
Freight shows how regulation can reach the payment record itself. In the United States, federal regulation 49 CFR 371.3 requires a freight broker to keep a record of each transaction showing, among other things, the compensation received for the brokerage service and who paid it, to keep those records for three years, and it gives each party to a brokered transaction the right to review the record. On an illustrative load where the shipper pays $2,000 and the carrier is paid $1,700, the broker's margin is $300, or 15% of the shipper's rate.
How is a commission split inside a brokerage firm?
A commission is paid to the brokerage, not to the individual, and the firm then divides it in a fixed order: outside parties first, then the house and the broker under their split, then any team or internal referral shares. In licensed industries the law often requires this route, with the firm or the broker of record receiving the fee and paying the individual.
The order of deductions is the part to pin down, because each share is a percentage of what is left after the previous one:
- Co-broker or cooperating broker share, where another firm brought the other side of the deal. It is usually expressed as a percentage of the gross fee.
- Outside referral fee, where a third party introduced the client. Agreements differ on whether it comes off the gross fee or off one side's share only.
- Franchise, desk or transaction fees charged by the firm or its network, where they apply.
- The house split between the firm and the broker: 50/50, 60/40, 70/30 and so on, sometimes on a graduated scale that improves as the broker's production for the year rises.
- Team shares, where a team leader, a junior broker or an analyst takes part of the broker's side.
A cap changes the fourth step. Under an illustrative arrangement where the house keeps 40% until it has received $20,000 from a broker in a year, the cap is reached after $50,000 of gross fees. A $30,000 fee earned before the cap leaves the broker $18,000; the same fee earned after the cap leaves the whole $30,000, less any fixed transaction fee.
Every share named in that list is a separate payment unless something makes it one. Where the client's single payment has to reach a co-broker, a referrer and the firm, a payment router such as Shaka can carry it: each party's share is set as a percentage of the deal and can be signed by that party before the client pays, the client pays once, and every party is paid at the same moment, in one final transaction, up to 20 recipients. It routes the payment and never holds the funds. It does not replace the closing agent, and it does not compute the internal house split, which remains a matter between a firm and its brokers.
What does a commission look like from the contract price to the broker's pocket?
A commission goes through five computations between the contract and the individual broker: the fee on the base, the part due now against the part deferred, the credit for any retainer, the co-broker's share, and the house split. The worked example below runs one sale through all five.
The assumptions, all illustrative: a business sells for $4,000,000, of which $3,200,000 is paid in cash at closing and $800,000 is a seller note payable later. The engagement letter sets the three-tier marginal scale used above (8% on the first $1,000,000, 5% on the next $1,000,000, 3% above), computed on total consideration including the note. The fee on the note is payable when the note is paid. A $15,000 retainer was paid at signing and is credited against the success fee. A second firm that brought the buyer takes 30% of the gross fee. Inside the selling firm, the broker receives 60% and the house 40%.
- Compute the fee on the base8% of the first $1,000,000 is $80,000. 5% of the next $1,000,000 is $50,000. 3% of the remaining $2,000,000 is $60,000. Total fee: $190,000, an effective rate of 4.75% of the price.
- Separate what is due nowCash at closing is 80% of the consideration, so 80% of the fee, $152,000, falls due at closing. The other 20%, $38,000, falls due when the $800,000 note is paid.
- Credit the retainerThe $15,000 already paid comes off the amount due at closing. The invoice at closing is $137,000; the fee earned at closing is still $152,000.
- Pay the co-broker30% of the $152,000 is $45,600 for the buyer-side firm. The selling firm keeps $106,400, made of $91,400 kept from the closing payment and the $15,000 retainer.
- Apply the house split60% of $106,400 is $63,840 for the broker and 40% is $42,560 for the house. When the note is paid, the $38,000 divides the same way: $11,400 to the co-broker, $15,960 to the broker, $10,640 to the house.
Illustrative scale, shares and amounts. Taxes, transaction fees and expenses are left out.
Across both payments, the co-broker receives $57,000, the house $53,200 and the broker $79,800, which together make the $190,000. The broker's share is 42% of the gross fee and just under 2% of the price. Had the same scale been read as a sliding scale, the gross fee would have been 3% of $4,000,000, or $120,000, and every figure below it would have shrunk by the same proportion: the choice of method moved $70,000.
One detail deserves a second look in any real agreement: the broker waits for $15,960 until the buyer pays the note, so part of the broker's income depends on a business the broker no longer has any hand in.
Who pays the commission, what rates are usual, and what protects it?
The party who signs the brokerage agreement owes the commission, although the money often comes out of the deal's proceeds, so that the other side bears part of it economically. Who pays varies by industry and by deal: the seller in most asset sales, the insurer in insurance, the shipper through the rate in freight, and either side or both in business sales and commodities.
Customary rates differ too widely across industries to be summarised honestly in a line, and a rate quoted without its base and method tells you little, as the scale example shows. Compare offers by computing the fee in dollars on two or three realistic prices, not by comparing percentages.
Protection rests on paper. A written fee agreement signed before the introduction, naming the rate, the base, the trigger, the payment date and a tail period, is what a court or a closing agent will look at; in several jurisdictions and industries an unwritten or unlicensed claim to a commission cannot be enforced at all. Each of these three subjects has its own rules and deserves separate study before you sign.
What should you check before you agree a commission structure?
Before you agree a commission structure, compute the fee in currency on at least two prices, then confirm that the agreement states the base, the method, the trigger, the payment date and the order of every split. A structure you cannot compute to the dollar from the text alone is not finished.
A working checklist:
- The formula: rate, flat amount or scale, with any minimum fee and any cap written as amounts.
- The method of any scale: bracket by bracket or whole amount, with one computed example in the text.
- The base: what is included (debt assumed, deferred payments, earn-outs, non-cash consideration) and what is excluded (taxes, pass-through costs, credits).
- The trigger: introduction, signed contract or completion, and what happens if the client withdraws or defaults.
- The payment: out of proceeds or on invoice, within how many days, in which currency, and how the fee on deferred consideration is handled.
- Any retainer: its amount, whether it is refundable, and whether it is credited against the success fee.
- Reversals: whether any part of a fee already paid can be clawed back, and on what event.
- The splits: every outside share with its percentage and the amount it is a percentage of, then the internal split, in order.
- The period: the term of the agreement, exclusivity, and the tail that covers introductions made during the term.
Run the numbers once on a low price and once on a high one. If the fee at the high price is not clearly more than at the low one, or if two readers of the same clause reach two different totals, the clause needs another draft before the deal needs a broker.
