Commission Calculator
Calculate sales commission earnings
About the Commission Calculator
For anyone paid on what they sell, knowing the commission before payday matters. This calculator takes a sales amount and a commission rate, adds any fixed base salary, and returns the commission earned and the total take-home.
Salespeople use it to forecast a paycheck from a strong month; managers use it to model what a rate change would cost; recruiters use it to explain an offer's earning potential. Because it folds in an optional base salary, it works for pure-commission roles and for the common base-plus-commission structure alike. Rerunning the numbers with a different rate or sales figure takes seconds, which makes it easy to see what hitting next month's target would actually pay.
How to Use the Commission Calculator
- Enter the total sales amount the commission is based on.
- Enter your commission rate as a percentage.
- Optionally enter a fixed base salary to add on top.
- Read the commission earned and the combined total earnings, then Copy the breakdown.

Frequently Asked Questions
How is sales commission calculated?
Multiply the sales amount by the commission rate as a decimal: 5% commission on $40,000 of sales is 40,000 × 0.05 = $2,000. If you also receive a base salary, the calculator adds it to give your total earnings.
Does this handle tiered or graduated commission?
It calculates a single flat commission rate plus an optional base. For a tiered plan where different rates apply to different sales bands, calculate each band separately at its own rate and add the results together.
Should commission be figured on revenue or profit?
That depends on your plan — some pay on gross sales revenue, others on profit or margin. Enter whichever figure your agreement is based on as the sales amount, and apply your contracted rate to it.
What is a typical commission rate?
Rates vary widely by industry — retail and many sales roles sit in the low single digits, while real estate commissions are often around 5–6% and some high-value B2B deals run higher. Enter the rate your specific agreement specifies; this calculator works for any percentage.
