Check commission earnings, rates, and payout scenarios
Use the commission calculator to estimate earnings from sales value and commission rate. It is useful for checking a simple percentage plan, comparing offers, or reviewing whether a quoted payout follows the stated compensation rules.
Formula
Worked example
For $25,000 of eligible sales at a 4% commission rate, estimated commission is $1,000. The eligible sales definition matters: returns, discounts, taxes, shipping, and uncollected invoices may be excluded by the plan.
Define eligible sales before applying the percentage
A commission rate is only one part of a compensation plan. The plan should identify whether commission is based on booked revenue, collected revenue, gross profit, units, or another measure, as well as how cancellations and returns are handled.
Use the amount that the written plan treats as commissionable. Applying the correct percentage to the wrong sales base is one of the easiest ways to create a payout mismatch.
Model tiers and accelerators one band at a time
Tiered plans may apply a higher rate only to sales above a threshold, or they may apply the achieved rate to the whole period. These approaches can produce very different results.
For a marginal tier plan, calculate each band separately and add the commissions. Also check caps, clawbacks, splits, bonuses, payout timing, and quota rules before treating the estimate as final earnings.
Commission-plan details to confirm
- Identify the commissionable sales base and measurement period.
- Check whether tiers are marginal or retroactive.
- Account for returns, cancellations, splits, caps, and clawbacks.
- Separate earned commission from the date it becomes payable.
