What it calculates: Total Commission, Quota Attainment, Commission at Base Rate, Accelerator Earnings.
Updated 5 June 2026 · Transparent assumptions
Two rates, applied to two slices, not one rate to the whole
Revenue up to quota earns the base rate; only the amount above it earns the accelerator. A rep at 120% of a 100,000 quota on 8% and 12% earns 8,000 on the first 100,000 and 2,400 on the excess — not 12% of the whole 120,000.
Reading the plan the second way is a common and expensive misunderstanding in both directions: reps expect more than they receive, and finance budgets more than it owes.
It sits between the two rates and moves with attainment
Total commission divided by total revenue gives the blended rate the plan really pays. Below quota it equals the base rate; above it, it climbs toward the accelerator as the over-quota portion grows, without ever reaching it.
This is the figure to model when sizing a commission budget, because it is the one that scales with performance. Budgeting at the base rate underfunds a good year, and budgeting at the accelerator overfunds every other one.
Quota percentage drives accelerators, cliffs and everything else
Attainment — revenue as a percentage of quota — is what most plan mechanics key off. Accelerator tiers trigger at attainment thresholds, bonuses land at 100%, and president’s-club style qualifications are usually stated in the same terms.
It also makes performance comparable across territories with different quotas, which raw revenue does not. A rep at 105% of a large quota and one at 140% of a small one are doing different jobs, and attainment is the only one of the two numbers that says so.
Cliffs, caps, draws, clawbacks and what counts as revenue
A two-rate structure is the common core, but plans layer on terms that change the answer: a cliff paying nothing below a threshold, a cap limiting upside, a recoverable draw advanced against future commission, and clawbacks when a customer cancels or fails to pay.
The revenue definition matters too. Commission may be calculated on bookings, on billings, or only on cash collected, and on net revenue after discounts rather than gross. Confirm which before treating any commission figure as owed.

Published the calculator with its formula, worked example, assumptions, limitations and a bespoke guide, and added an automated formula test suite covering it.
Tested the split between base-rate commission up to quota and accelerator commission above it, with attainment and the blended effective rate.
Tested that revenue at or below quota earns the base rate alone, and that the effective rate always sits between the two rates once quota is passed.
