Commission Calculator calculator

Commission earned on a sale from the sale amount and commission rate, plus any base pay.

Published 21 August 2026

What this calculator does

A commission calculator works out how much a salesperson earns on a sale, by multiplying the sale amount by an agreed commission rate. It applies to any commission-based role: retail sales, wholesale accounts, insurance policies, car sales or anything else where pay is tied to a percentage of what was sold, rather than to any single industry.

The part people get wrong is mixing up the commission rate with the take-home percentage. A 10% commission rate on a $5,000 sale is $500, not $5,000 minus 10%. If there is also a base salary or retainer for the period, that gets added on top of the commission, not folded into the rate.

The formula

FormulaCommission = Sale amount × Commission rate; Total pay = Commission + Base pay

Multiply the sale amount by the commission rate to get the commission earned. If there is a base pay or salary for the period being measured, add it to the commission to get total pay for that period.

TermMeaning
Sale amountThe value of the sale the commission is calculated on, before the commission is deducted.
Commission rateThe agreed percentage of the sale amount paid to the salesperson.
Base payAny fixed salary or retainer paid regardless of sales, added on top of commission.

The inputs explained

FieldWhat to enter
Sale amount ($)The total value of the sale, or the sum of sales, the commission is being calculated on.
Commission rate (%)The commission rate agreed for this sale, as a percentage.
Base pay for the period (0 if none) ($)Any base salary or retainer for the same period, entered as 0 if pay is commission-only.

When to use it

Commission-only sales roles

Some sales jobs pay purely on results: enter the sale amount and rate, leave base pay at zero, and the commission earned is the whole of the pay for that sale.

Base plus commission structures

Many roles pay a smaller guaranteed base alongside commission. Entering the base pay alongside the sale and rate shows total pay for the period, not just the variable part.

Checking a payslip or commission statement

If a commission statement lists a sale amount and a rate, recalculating independently confirms the commission paid matches what was agreed.

How commission earned changes with the rate on a $5,000 sale

The same $5,000 sale, across a range of commission rates.

$5,000 sale amount
Commission rateCommission earnedTotal pay (commission + base)
2%$100.00$100.00
5%$250.00$250.00
7.5%$375.00$375.00
10%$500.00$500.00
15%$750.00$750.00
20%$1,000.00$1,000.00
Commission scales directly with the rate: doubling the rate doubles the commission on the same sale amount.

How commission earned changes with sale size at a fixed 10% rate

A fixed 10% rate applied to a range of sale amounts.

10% commission rate
Sale amountCommission earnedSale amount
$1,000$100.00$1,000.00
$2,500$250.00$2,500.00
$5,000$500.00$5,000.00
$10,000$1,000.00$10,000.00
$25,000$2,500.00$25,000.00
$50,000$5,000.00$50,000.00
At a fixed rate, commission rises in direct proportion to the sale amount.

Questions

Is this the same as real estate commission?

The maths is the same, sale amount times rate, but real estate commission usually has its own conventions, such as splitting the rate between listing and selling agents. For a property sale specifically, the real estate commission calculator is set up for that case.

What is a typical commission rate?

It varies enormously by industry, product margin and whether there is also a base salary, from under 1% on high-value wholesale deals to 20% or more on some retail or door-to-door sales. There is no single benchmark worth quoting, so use the rate actually agreed in your contract.

Does commission get taxed differently to a salary?

In most places commission is taxed as ordinary income, though how much is withheld from any single payment can differ depending on payroll rules. Check with a payroll or tax professional for how it is treated where you are.

How do tiered commission structures work?

Some plans pay a higher rate once sales pass a threshold, for example 8% up to a target and 12% above it. This calculator handles a single flat rate; a tiered plan needs the relevant tier applied to each portion of sales separately.
