Commission Calculator
Commission pay ties your earnings to what you sell. Enter the sale amount, your commission rate, and any fixed base pay to see the commission earned, your total pay, and how much of it rides on the sale.

How this calculator works
Commission = sale amount × commission rate. Total pay adds any fixed base. The commission share is commission ÷ total pay — a quick read on how variable your income is.
This models a single flat rate on one sale amount. Real plans can use tiered rates, quotas, accelerators, or splits; for those, run each tier's sales separately and add the results. Figures are gross, before taxes and withholding.
Formula
Commission = Base × rate
Total pay = Salary + Commission- Base
- Revenue, gross profit or net — plans differ, and so does the result
- rate
- Commission rate, as a decimal
Tiered plans and accelerators above quota are not modelled by a single rate, and that is usually where most of the upside sits. Commission is typically withheld at the flat supplemental rate rather than at your marginal rate.
What this assumes
- The commission structure you enter, applied to the base shown. Tiered and accelerator structures behave differently.
- No clawbacks for cancelled or returned business, which many plans include.
- Taxes are not applied — commission is typically withheld at the flat supplemental rate rather than at your marginal rate.
What changes this number
- Rate and tier structure
- Accelerators above quota change the maths entirely, and are where most of the upside sits.
- The base it applies to
- Revenue, gross profit or net differ enormously on the same sale.
- Timing of payment
- Commission is often paid on collection rather than on signature, which shifts the cash flow by months.

Frequently asked questions
How do I calculate commission?
Multiply the sale amount by the commission rate. A 5% commission on a $50,000 sale is $50,000 × 0.05 = $2,500. If you also get a base salary or draw, add it to the commission for your total pay. This calculator handles both and shows what share of your pay is commission.
What is a base plus commission structure?
It pays a guaranteed base salary plus commission on sales, blending stability with upside. The base covers your essentials in a slow month while commission rewards performance. A pure-commission job has no base — every dollar depends on sales — so it carries more risk and usually a higher rate.
What is a commission draw?
A draw is an advance against future commissions — the company pays you a set amount up front, then recovers it from the commissions you earn. It smooths income in slow periods, but a 'recoverable' draw must be paid back from later commissions, so it's a loan against your own future sales, not extra pay.
Is commission taxed differently?
Commission is taxable income like your salary, but employers often withhold it at a flat supplemental rate (22% federally for amounts under $1 million), which can differ from your regular withholding. Your actual tax depends on your total annual income — see the Take-Home Pay calculator for the net effect.
