Formula and assumptions

Simple commission: commission = eligible base x rate x split. Net revenue base is gross sales - deductions. Gross profit base is gross sales - deductions - costs.

Tiered mode uses marginal brackets, not retroactive tiers. Quota mode pays the base rate up to quota and the accelerator rate only on the eligible amount above quota. Recoverable draw mode subtracts the draw from commission and can create a carry-forward shortfall; non-recoverable draw mode treats the draw as guaranteed period pay.

Before comparing plans, confirm the measurement period, whether deals count when booked or collected, how refunds are handled, and whether rates apply to revenue, gross profit, or another eligible base. Small plan details can change payout timing and the final amount.

This calculator is for planning and education, not payroll, tax, legal, or financial advice. Actual commission pay can depend on contract terms, booking rules, payment collection, clawbacks, caps, taxes, deductions, territory credit, and employer policy.

Commission Calculator FAQs

How do I calculate commission from sales?

Multiply eligible sales by the commission rate. For example, 50,000 at 5% produces 2,500 in commission before any split, draw, bonus, or base pay adjustment.

Should I use revenue or gross profit as the commission base?

Use the base stated in your commission plan. Revenue-based plans use net sales after returns or credits. Gross-profit plans subtract cost of goods or delivery costs before applying the rate.

Are tiered commissions additive?

Marginal tiers are additive by bracket. If the first 25,000 pays 4% and the next 25,000 pays 6%, each slice uses its own rate. This differs from a retroactive plan where hitting a threshold changes the rate for the whole amount.

How does the draw calculation work?

A recoverable draw is subtracted from earned commission; if the draw is larger than commission, the shortfall is shown. A non-recoverable draw is treated as guaranteed pay for this estimate.

Does this calculate taxes?

No. It estimates gross pay before taxes, benefit deductions, withholding, or payroll adjustments.

Why model splits and bonuses separately?

Splits usually reduce the commissionable share of a sale, while bonuses are added after the core commission math. Keeping them separate makes it easier to audit a plan and explain the result.
