This works out commission from a sale amount and rate, including tiered and split structures.
It gives the commission, the effective rate, and total earnings where there is a base salary as well.
How sales commission is calculated
Commission is a percentage of a sale paid to whoever made it. The arithmetic is one multiplication, and everything difficult about it is in the structure.
The first thing to understand is the split. In real estate, a "5.5% commission" on a $400,000 sale is $22,000, but that is divided between the listing side and the buying side, and each agent then splits with their brokerage. Nobody receives $22,000.
The second is tiers. A schedule paying 5% up to $50,000 and 8% above it does not pay 8% on everything once you pass $50,000. Each band keeps its own rate, exactly like income tax brackets.
Not $75,000 × 8% = $6,000. Each band is paid at its own rate, so the effective rate sits between the two.
What to enter
- Sale amount
- The value commission is calculated on. Check whether that is gross revenue or profit, since the difference is large.
- Commission rate
- The percentage. Varies enormously by industry, from around 1% on high-value goods to 20% or more on services.
- Split
- What share reaches you after any brokerage or team split. Real estate commonly splits several ways.
- Base salary
- Where the role pays both. Total earnings are base plus commission, and the mix tells you a lot about the job.
Commission structures
- Straight commission
- No base salary. Highest earning potential and highest risk.
- Base plus commission
- A salary with commission on top. The most common structure in sales roles.
- Tiered
- The rate rises as you sell more, band by band. Designed to reward performance above target.
- Draw against commission
- An advance you repay from future commission. Recoverable draws create real debt if you underperform.
- Residual
- Ongoing commission while the customer keeps paying. Common in insurance and subscription software.
What this assumes
Tiered rates apply band by band unless a schedule explicitly says otherwise. Some retroactive schedules apply the higher rate to everything, and those are worth reading carefully.
Commission is ordinary income, and is often withheld at a higher supplemental rate than regular wages.
How to calculate a commission payment
One multiplication per band, then apply any split.
- amount in each band
- Only the portion inside that tier, not the whole sale
- split
- Applied afterwards, to what reaches you rather than what was charged
Check what the rate applies to. Gross revenue or profit. A 10% commission on profit is a very different job from 10% on revenue.
Apply each tier separately. Fill the lowest band first at its rate, then the next. Only the top portion earns the top rate.
Apply the split. Brokerage, team and referral splits all come off before the money reaches you.
Add any base salary. For total earnings. Also work out the effective rate, since it is the honest comparison between offers.
See a worked example: a tiered schedule, and a real estate split
- Tiered
- 5% to $50,000, 8% above, on $75,000 of sales
- Real estate
- 5.5% on a $400,000 sale
Tiered: $50,000 × 5% = $2,500, plus $25,000 × 8% = $2,000, so $4,500. That is an effective 6%, not 8%.
Real estate: $400,000 × 5.5% = $22,000 total commission.
Split between listing and buying sides: $11,000 each.
Then each agent splits with their brokerage. On a 70/30 split the agent receives $7,700, which is 1.93% of the sale price.
$4,500 tiered; $7,700 to the agent on the $400,000 sale
Frequently asked questions
Each band is paid at its own rate. On a 5%-to-$50,000-then-8% schedule, selling $75,000 pays $2,500 on the first band and $2,000 on the second, so $4,500.
It is not $75,000 × 8%. The same misunderstanding that makes people fear tax brackets applies here, and it works the same way.
Far less than the headline. A 5.5% commission on $400,000 is $22,000, split between the two sides to give $11,000 each, then split again with the brokerage.
On a 70/30 brokerage split the agent receives $7,700, before their own marketing costs, licensing fees and self-employment tax.
It is ordinary income, taxed at the same rates as salary. What differs is the withholding: as supplemental wages it is often withheld at a flat federal rate rather than through your normal W-4 calculation.
That can mean over- or under-withholding during the year, which settles at filing. It is a cash flow difference, not a tax difference.
An advance on future commission, so you have income in slow months. A recoverable draw must be paid back out of later commission; a non-recoverable one does not.
The distinction matters enormously. A recoverable draw in a bad quarter is a debt to your employer, and it is worth confirming which type an offer means.
Either, and it changes the job completely. Revenue-based commission rewards volume; profit-based rewards margin and discourages discounting.
It also affects how much control you have. Profit-based commission can fall because of costs you did not incur, so ask exactly how it is defined.
Entirely industry-dependent, so the rate alone means nothing. High-value goods often pay 1-3%; services and software commonly pay 10-20%.
Compare total expected earnings rather than the percentage: base salary, realistic volume, the split, and how attainable the quota is.
Problems people actually run into
Applying the top tier rate to the whole amount
Reaching the 8% band does not make everything pay 8%. On $75,000 the commission is $4,500, not $6,000.
Work band by band. If a schedule genuinely is retroactive, it will say so explicitly, and that is worth confirming rather than assuming.
Judging a commission-heavy offer on the headline rate
A 10% rate sounds far better than 3% until you know the deal sizes, the quota, and the split. 3% on large volume routinely beats 10% on small.
Ask what people at the level actually earned last year, not what the plan makes possible. On straight commission, also ask how long the ramp takes.
