Commission Calculator

Enter the sales amount, commission rate, and base salary to find the total pay.

How it is calculated

The tool applies one flat percentage to the whole sales figure: commission = S × r ÷ 100 and total pay = B + commission, where S is the sales amount for the pay period, r is the commission rate in percent (6.5 means 6.5%, not 0.065) and B is the base salary for the same period. All three fields are required and must be zero or more; for a straight-commission job with no base, enter 0 as the base salary. Amounts are shown in dollars with two decimals. The tool has no tiers, caps, thresholds or deductions, and the result is before any tax or withholding.

Worked example

A salesperson has a base salary of $2,500 for the month, a 6.5% commission rate and $48,000 in sales. Commission: 48,000 × 6.5 ÷ 100 = $3,120.00. Total pay: 2,500 + 3,120 = $5,620.00. The commission part is more than the base, so about 55% of this paycheck depends on sales. If the plan pays a higher rate above a quota, this flat result will understate the pay.

Common mistakes

  • Entering the rate as a decimal (0.065) instead of a percent (6.5); the result would be 100 times too small.
  • Mixing periods: a monthly base with yearly sales, or the reverse. Use the same period for sales and base salary.
  • Using this flat tool for a tiered or accelerator plan, where the rate rises above a quota; it applies one rate to every dollar.
  • Treating the result as take-home pay; it is gross, before income tax and other deductions.
  • Applying the rate to gross sales when the plan pays on profit, margin or net sales after returns; use the amount your plan actually defines.

About this calculator

Many sales roles pay a base salary plus commission: a guaranteed base amount every pay period, topped up with a percentage of whatever sales the employee closes — total pay equals base salary plus (sales amount times commission rate). This flat-rate structure is one of the most common compensation plans in retail, real estate, and B2B sales, distinct from a pure straight-commission plan (no base at all) or a tiered plan where the rate increases at higher sales volumes.

Entering the sales amount, commission rate, and base salary shows the total pay for a period, which is useful both for employees estimating a paycheck and for employers modeling compensation costs against expected sales volume.

    If your plan pays a higher rate above a quota, you can still use this by splitting the sales in two runs. Enter the sales up to the quota at the lower rate with your base salary, then the sales above it at the higher rate with the base set to 0, and add the two totals. For example, 40,000 at 5% gives 2,000 of commission. What does your plan look like: tiers, a cap, or a draw against future commission?
