Royalty audit exposure estimator.

Royalty audit exposure is the estimated additional royalties — plus any contractual interest or penalties — a licensor audit could assess if your reported royalties were understated across the lookback period. Enter your reported net sales, royalty rate, a self-assessed error estimate, the audit lookback, and any contractual interest rate to see a directional exposure range. Every figure comes from your own inputs — no benchmarks, no signup, no email.

// Start from a worked example

A scenario input you set — not a benchmark, industry figure, or prediction. Model the error rate you want to pressure-test.

Defaults to 0. If your agreement charges interest on underpayments, enter the annual rate to see the interest-inclusive high end of the range.

How royalty audit exposure works

What is royalty audit exposure?

Royalty audit exposure is the estimated additional royalties — plus any contractual interest or penalties — a licensor audit could assess if reported royalties were understated across the audit lookback period. It is the downside a licensee is quantifying when it self-assesses the risk in its royalty statements before a licensor audit firm does.

How does this estimator work?

It multiplies your reported net sales by your royalty rate to get reported royalties, applies your own underreporting/error estimate to project under-reported royalties per year, multiplies by the audit lookback, and adds simple interest at your contractual rate to produce a directional exposure range. Every figure derives from the numbers you enter — there are no built-in benchmarks.

Is the underreporting rate a benchmark or a prediction?

Neither. The underreporting/error rate is a scenario input you set — labeled "your estimate" — so you can pressure-test different assumptions. The tool does not supply an industry error rate and does not predict your actual exposure. The result is a directional estimate from your own inputs, not an assurance; actual exposure depends on your contract terms and the licensor’s audit methodology.

What actually drives royalty audit findings?

The recurring causes are stale-master drift (a rate change that never propagated to the calculation), disallowed deductions netted out of the royalty base, missed cooperative-mark splits, returns-lag and true-up attribution errors, and mistakes in advance recoupment, minimum guarantees, or cross-collateralized pools. Each compounds quietly across periods until an audit prices them together — which is why an immutable audit trail and structured contract terms are the real defense.

This sizes the risk. Royalty Reporting removes the structure that creates it.

An immutable audit trail at every calculation, versioned rate cards, and per-period attribution — live in days, so an audit response is document production, not a forensic rebuild.
