How this instrument works
Commission ties pay to the size of a transaction rather than to hours worked, so the arithmetic is a single proportion. Dividing the rate by 100 turns a percentage into a plain multiplier, and that multiplier is applied to whatever the agreement names as the base — five percent means five cents of every dollar in it. The base is where nearly all the disagreement lives: a plan can pay on invoiced revenue, on the price surviving returns and freight, or on gross profit, and those three numbers can sit an order of magnitude apart on the very same deal.
The second readout looks at that transaction from the other chair. Whoever pays keeps sale × (1 − rate ⁄ 100), the complement of the payout, so the pair always lands back on the sale figure. Type a rate of 6 against a $300,000 house and you see $18,000 leaving and $282,000 remaining. Worth noticing that the fee is a share of the price, never a share of the owner's equity — a seller holding $40,000 of equity in that house parts with close to half of it.
One flat percentage rarely survives contact with a real plan. Tiered schedules lift the rate once quota clears, splits divide the same fee twice over, draws advance money that later payouts repay, and clawbacks reverse everything if a customer cancels. Payroll adds another layer, since a fee paid to an employee counts as supplemental pay and arrives already withheld. What this instrument reports is the gross earned amount: the arithmetic before the plan document, the brokerage split and the tax code each take their turn.
- Type whatever the rate is charged against into Sale amount, $ — the contract price, the invoice total, or the gross profit figure if that is what your plan pays on.
- Set Commission rate, % to the percentage written into the agreement: 5 for a flat five percent, 2.5 for one side of a split, 0.6 for a renewal year on an insurance book.
- Read Commission earned for the gross payout, and Amount left after commission for what stays with the party writing the cheque.
- Add the two readouts together. They must land back on the sale figure, which catches a mistyped rate faster than reading the entry again.
Worked example — a $10,000 order at 5%
A field rep closes a $10,000 equipment order on a plan paying 5% of invoiced revenue. Put 10000 into Sale amount, $ and 5 into Commission rate, %. Five percent is the multiplier 0.05, so Commission earned reads $500.00 and Amount left after commission reads $9,500.00. Adding them returns 10,000 exactly, which is the whole check.
Neither number is money in a pocket yet. Paid through payroll, that $500 is supplemental pay and may be withheld at the flat 22% federal figure, landing nearer $390 once Social Security, Medicare and state tax are through with it. The $9,500 is not profit either — it still owes the cost of the goods, the freight and the card processing fee. Nudge the rate to 6 and the payout becomes $600 against $9,400 remaining: on a sale this size, every tenth of a point moves $10.
Questions
How do I work out a commission?
Multiply the base by the rate expressed as a decimal. Five percent of a $10,000 sale is 10,000 × 0.05 = $500, leaving $9,500 behind. Mental shortcuts follow the same pieces: 10% is the figure with its decimal point shifted one place left, 1% is two places, and most contract rates are assembled from those two. A 7.5% fee on $10,000 is 1,000 minus a quarter of it, or $750.
Is the fee charged on revenue or on gross profit?
Whichever the plan names, and the gap between them is enormous. Real estate and most retail schemes pay on the sale price, while car dealerships and many distributors pay on front-end gross — the margin, not the sticker. A $32,000 vehicle carrying $900 of gross at a 25% rate returns $225, not the $8,000 a rate applied to the sticker would suggest. The plan document names the base, and that line is worth reading before any two rates are compared.
Why is my agent's share smaller than the percentage on the listing agreement?
Because the money is divided at least twice before anyone banks it. A total real estate fee is normally split between the listing side and the buyer side, then each brokerage splits again with its agent — a 70/30 arrangement on half of a 6% fee leaves the agent roughly 2.1% of the price, before desk fees, MLS dues and errors-and-omissions cover. Since August 2024, buyer-side compensation in the United States is negotiated separately rather than advertised on the MLS, so the single headline percentage may now be two numbers.
How much tax comes out of a commission cheque?
That depends on how you are paid, not on the payout itself. An employee's fee counts as supplemental wages, and the IRS permits employers to withhold a flat 22% federal on supplemental pay up to $1 million in a year, with 37% applying above that line, on top of Social Security, Medicare and any state withholding. An independent contractor receives the gross, gets a 1099, and settles income and self-employment tax personally. Withholding is not the final bill either — the annual return reconciles it. This sheet reports gross only.
What is a draw against commission?
An advance the employer pays during a quiet month and recovers from later earnings. A recoverable draw of $2,000 set against $500 earned leaves $1,500 carried forward as a debit; a non-recoverable draw behaves as a floor and is never repaid. The instrument computes the earned figure alone, because the draw ledger is a running balance across periods rather than anything the sale amount can express.
Can a payout be taken back after it lands?
Yes, and the trigger sits in the plan document. Refunds, cancellations, invoices that go unpaid, and in insurance a policy lapsing inside its first year, all commonly reverse the fee in whole or in part — the chargeback. Run the figures again on the amount that actually stuck rather than the amount originally booked: a $10,000 order half returned pays on $5,000, so the earned total falls to $250 and the payer retains $4,750.
