Sales commission calculator

This calculator estimates a simple commission plan for sales reps, managers, freelancers, and small teams. Enter your period sales, commission rate, and base salary: you get the exact commission, total income, and how much more you need to sell to hit an income target.

Quick answer (calculator defaults)

With 25,000 in sales, a 5% commission, and a 3,000 base salary:

  • Commission: 1,250
  • Total income: 4,250
  • Sales needed for a 5,000 target: 40,000 (15,000 more in sales)
  • Income gap: 750 to the target

Formulas

Commission

Commission = Period sales × (Commission percent / 100)

Total income

Total income = Base salary + Commission

Sales needed for target

Sales needed = (Income target − Base salary) / Commission rate

Step-by-step example (calculator defaults)

  1. Period sales = 25,000.
  2. Commission = 25,000 × 5% = 1,250.
  3. Total income = 3,000 + 1,250 = 4,250.
  4. Target of 5,000: the commission needed is 5,000 − 3,000 = 2,000; at 5% that requires 40,000 in sales.
  5. Additional sales = 40,000 − 25,000 = 15,000; the income gap is 750.

Interpreting the result

  • The base drives everything: with a high base salary you need fewer sales to cover your income, but your ceiling is lower too. Compare complete plans, not just the rate.
  • Use the inverse result to negotiate targets: to earn 6,000/month at 7% with a 2,500 base, the realistic sales target is 50,000, as the table shows.
  • Common mistakes: applying the rate to the price with VAT when the contract uses net sales, forgetting returns, and calculating the target without subtracting the base salary.
  • Check the target against business profitability to make sure the sales you reward also leave profit.
Limits

This page covers the common linear plan. If commission changes by tier, calculate each tier separately and add the results. Amounts shown are gross: taxes and withholdings depend on your regime and country; check with your accountant or tax authority.

Frequently asked questions

Multiply the amount sold by the commission rate, then add the base salary. Example: 25,000 × 5% = 1,250; with a 3,000 base, total income is 4,250.

Subtract the base salary from the target and divide by the commission rate: (5,000 − 3,000) / 5% = 40,000 in sales.

It depends on the contract. Some teams use gross sales, collected sales, sales before VAT, or gross margin. Confirm the base before calculating: the result changes a lot between options.

Compare the calculated result with the cap. If it exceeds the allowed maximum, use the cap as the final commission for the period.
