Tiered commission review for one invoice
Calculate marginal commission band by band from your verified terms. Compare the result with a recorded fee without treating the lowest or highest rate as a rate for the entire invoice.
Free to use · Fictional examples · Local calculationReview the marginal fee deducted against one invoice, using one verified AUD commissionable base and two to eight marginal bands.
Review the verified marginal schedule
All prefilled figures are fictional. Verify the applicable method, base and rounding policy first. Flat fees, minimum fees, caps, negative amounts, tax on fees, unapproved exclusions and mixed currencies are not calculated here.
Confirm the scope, then review the inputs.
Fictional four-band example
For a base of AUD3,500: first 1,000 at 10%=100; next 1,000 at 5%=50; next 1,000 at 3%=30; remaining 500 at 1%=5. Total commission is AUD185. These are fictional rates, not a platform price schedule or a recommendation.
With the same bands, AUD500 gives 50 and an exact AUD1,000 base gives 100. Do not pool unrelated invoices to reach a lower band. A different real agreement may require a different method.
Rounding can matter: three portions of 0.01 at 50% each give 0.03 when each half-cent is rounded, versus 0.02 when their total is rounded. Check the policy in the actual source record.
How the review works
Each band takes only the part of the base above its lower threshold and up to its upper threshold. Multiply that portion by its percentage, then sum the band fees. The last band must use an asterisk (*) for no upper limit. Thresholds must strictly increase; rates must be between 0% and 100%.
The review shows both round-after-summing and round-each-band totals, using half-up rounding to cents. Choose the policy your records actually use. “Recorded minus calculated” is a difference to investigate, not proof of an incorrect deduction. Other charges or a different base can explain a difference.
Verify the records before preparing a document
Reconcile the fee with the actual statement and agreement. Keep platform-issued invoices and supporting records. This tool does not generate a replacement invoice, alter a customer debt, estimate tax or prove an amount was paid.

Sources and scope
Book An Artist’s published help page gives an example of marginal fees per invoice and explains exceptions where a different method applies. That supports the need to confirm the method first. This page does not import its rates, approve exclusions or predict platform payouts.
