Supported inputs and limits

Rates from 0 to 100%. Up to 50 strictly increasing cumulative upper limits; the final tier uses * for no upper limit. Tier rates apply marginally, not retroactively to all sales. No quotas, clawbacks, taxes or eligibility rules. Enter plain decimals with at most 64 characters, 25 digits and 12 fractional places. Monetary inputs are limited to 10^12. Very small or large nonzero amounts use scientific notation. Use one currency throughout; no exchange rates, taxes or fees are added unless you enter them.

Check whether the agreement uses marginal tiers

For 15,000 of sales, tiers of 10,000 at 5% and the remainder at 8% produce 500 plus 400. This differs from applying 8% to the entire amount after reaching a threshold. Returns, clawbacks and payment timing are outside the calculation; enter an adjusted eligible amount when appropriate.

Questions about Commission Calculator

What does the star in the final tier mean?

It covers all eligible amount above the previous upper limit, so the schedule has no uncovered final range.

Does reaching a tier change the rate on earlier sales?

No. This is a marginal schedule. Each rate applies only to the portion inside its own band.

Where do I include returns or deductions?

Enter the eligible amount after any adjustments required by your arrangement. The tool does not decide eligibility.
