Commission Calculator

This calculator multiplies a sale amount by your commission rate to show what a deal pays, then adds an optional fixed base salary to give total earnings. Every figure is rounded to two decimal places and formatted in the currency you pick, so you can read the numbers exactly as they would land on a payslip.

How to use the commission calculator

  1. Pick your currency from the menu in the top right if it is not already US dollars.
  2. Enter the total value of the deal in the Sale amount field.
  3. Set your commission rate in the Commission rate field, which reads as a percentage.
  4. If you draw a fixed salary, type it into the Base salary (optional) field, otherwise leave it at zero.
  5. Read the Commission, Base and Total earnings cards, where total earnings is commission plus base.

Examples

5% commission on a $10,000 sale, no base

Sale 10000, rate 5%, base 0
Commission 500.00, base 0.00, total earnings 500.00

The same sale with a $2,000 base salary

Sale 10000, rate 5%, base 2000
Commission 500.00, base 2000.00, total earnings 2500.00

A larger deal at 7.5% with a base

Sale 25000, rate 7.5%, base 3000
Commission 1875.00, base 3000.00, total earnings 4875.00

Frequently asked questions

How is sales commission calculated?

Commission is the sale amount multiplied by the rate as a decimal. For a 10,000 sale at 5 percent, that is 10,000 times 0.05, which is 500. The tool does this multiplication and rounds the result to two decimal places.

How do I add a base salary to commission?

Type your fixed base into the Base salary field. Total earnings are the base plus the commission, so a 2,000 base alongside a 500 commission gives 2,500. Leave the field at zero for a commission-only plan.

Does this handle tiered or graduated commission?

Not directly, because it applies one flat rate to the whole sale. For a tiered plan, run the calculator once for each tier at its own rate on that tier's portion of the sale, then add the commissions together.

Can it work out commission on gross profit or margin?

The tool multiplies whatever amount you enter by the rate, so enter the gross profit instead of the sale price if your plan pays on margin. It has no separate cost field, so you would compute the profit first.

Which currencies are supported?

You can switch the currency from the menu, and the results are formatted with that currency's symbol and two decimal places. Changing the currency only relabels the numbers, it does not convert exchange rates.

What is a typical commission rate?

Rates vary widely by industry. Many sales roles fall between 5 and 20 percent, while real estate and high-ticket deals often sit lower. Always use the exact rate from your own compensation plan.

Is commission figured before or after tax?

This is a gross figure before income tax and deductions. Commission is usually taxed as ordinary income, and some employers withhold it at a supplemental rate, so your take-home pay will be lower than the total shown.

What are the limits on the amounts I can enter?

The sale amount and base accept values up to 1,000,000 and the rate goes up to 100 percent. Negative numbers are not allowed, since a sale, rate and salary are all non-negative.

Is any of my data uploaded?

No. The calculation runs in your browser, so the sale figures and salary you enter stay on your device and are never sent to a server.
