Work out your commission payout, the rate you were paid, or the sales you need to hit a target — pick what you're solving for below.
Quick answers to the questions people ask most about commission.
Multiply the sales amount by the commission rate (as a decimal). For example, a 10% commission on $5,000 in sales is $5,000 × 0.10 = $500.
Divide the payout by the sales amount, then multiply by 100. A $500 payout on $5,000 in sales is (500 ÷ 5,000) × 100 = 10%.
Divide the target payout by the commission rate (as a decimal). To earn $500 at a 10% rate, you need $500 ÷ 0.10 = $5,000 in sales.
Commission is typically calculated on the pre-tax sales amount, then the resulting payout is itself subject to income tax when it's paid to you — check your specific pay structure, since this can vary by employer.
