What this calculator helps you decide
Best for
Estimating gross commission under a flat or three-tier marginal sales plan.
Outputs
Commission amount and total gross pay including base pay.
Start here
Choose the plan mode, then enter base pay, commissionable sales and its rates.
- Close-intent boundary
- Do not use this to value contingent bonus pay; use Bonus Calculator. Plans with caps, draws, clawbacks or more than three tiers need a separate model.

Commission: commission amount and total gross pay including base pay.
Commission amount and total gross pay including base pay.
Base pay and commission plan
Choose a flat rate or enter three marginal tiers with two bounded breakpoints.
Your numbers stay in this browser
Choose a flat rate or three marginal tiers.
Gross annual base pay before commission.
Sales or revenue amount covered by the commission rate.
Flat commission rate as a decimal, where 0.05 means 5%.
Calculated result
The result keeps base pay and selected-plan commission visible as separate parts of total gross pay.
Use one currency consistently across all inputs.

Commission: commission amount and total gross pay including base pay.
Use total pay only when the entered sales amount is fully commissionable under the selected flat or marginal-tier plan.
Formula summary
- Primary formula
- Flat-plan total gross pay: totalPay = basePay + salesAmount × commissionRate; Marginal-tier total gross pay: totalPay = basePay + commissionAmount
Data used here
- The estimate uses your inputs and the work-value formula documented in the methodology.
Decision checks
Act on the result
Verify the entered tier bounds and rates, plus any unmodelled caps, draws, returns and timing.
Stress-test the decision
Retest sales volume around a realistic low and high case.
When this estimate can be misleading
- Actual crediting, returns and timing may differ.
- Draws, clawbacks, caps and more than three tiers are not modelled.
- The result does not predict sales performance.
- Use total pay only when the entered sales amount is fully commissionable under the selected flat or marginal-tier plan.
