Sales commission calculator
The most common commission error is applying the accelerator rate to the whole year once a rep crosses quota, instead of only to the bookings above it. The second most common is splitting a deal that straddles two tiers at the wrong rate. This calculator works deal by deal against cumulative bookings, so every dollar lands in the right tier and the total reconciles to the statement.

How to use it
- 1
Enter plan inputs first
Target incentive and quota give you the base rate. Do not type the base rate in by hand; derive it, so a quota change flows through automatically.
- 2
Log deals in close-date order
Tiers depend on cumulative bookings, so order matters. Sort by the crediting date defined in the plan, not by the date the deal was entered in the CRM.
- 3
Split tier-crossing deals explicitly
When one deal carries the rep over a tier boundary, write the two portions on separate lines of the formula. This is where statements go wrong and where reps check first.
- 4
Reconcile every period
Payable this period = Commission earned this period - Advances already paid + Adjustments (clawbacks, corrections). If the reconciliation does not tie to the deal ledger, do not send statements.
Frequently asked questions
How do you calculate tiered commission?
Apply each tier's rate only to the bookings inside that tier's band, then add the results. On a $1,000,000 quota with 10% to quota and 15% above, $1,300,000 of bookings pays (1,000,000 x 10%) + (300,000 x 15%) = $145,000.
What is a commission accelerator?
A higher rate paid on bookings above a threshold, usually quota. It rewards over-performance and discourages reps from holding deals for the next period once they have hit their number.
Are commission accelerators retroactive?
Usually not. Most plans pay the accelerated rate only on bookings above the threshold. If a plan intends a retroactive accelerator, the plan document must say so, because it is far more expensive.
What is the difference between commission earned and commission paid?
Earned is what the rep is owed under the plan's earned definition, for example once the customer pays. Paid is what went out in payroll. Advances paid before the earned event are subject to clawback if the event never happens.
