Sales commission calculator
Model tiered commissions, accelerators, and kickers — and watch the payout curve respond. No signup. It follows the same tier math as the Earnest calculation engine, simplified to a single full month.
Simplified view: one rep, one plan, one full month, one currency. The full engine also handles proration for mid-month starts, quarterly seasonality, ramp schedules, quota-to-date true-ups, team rollups, and multi-currency — see everything it covers.
Not sure where to start? The comp plan templates each load here with worked numbers for a specific role, AE through SDR.
How the math works
Base commission
Revenue up to quota pays at your effective rate. In OTE mode that rate is derived the way the real engine derives it: (OTE − base salary) ÷ annual quota.
Accelerators
Revenue above a tier boundary pays at the rate × that tier's multiplier. A 1.5× tier from 100–150% means every dollar in that band earns one-and-a-half times the base rate.
Kickers
A milestone bonus that pays a percentage of monthly variable comp the moment attainment reaches the tier — a one-time step, not a rate change.
Caps and floors
A cap limits the total payout for the month; a floor guarantees a minimum. When both are set and conflict, the floor wins — same rule as the production engine.
Cost of sale
The cost panel shows base salary plus payout as a percentage of revenue. Because base salary is flat, the ratio usually falls as attainment climbs — watch whether your top accelerator makes it turn back up.
