Analyze patent royalties, fees, and tax effects. Compare sales, guarantees, and sublicensing terms. Turn licensing assumptions into payment insights for smarter negotiations.
This tool compares sales-based and unit-based royalties, then applies guarantees, fees, tax, escalation, and caps for a fuller licensing estimate.
| Scenario | Net Sales | Royalty Rate | Units Sold | Min Guarantee | Sublicense Income | Net Payable |
|---|---|---|---|---|---|---|
| Standard License | 1,500,000 | 5% | 50,000 | 90,000 | 120,000 | 111,847.50 |
| High Volume Distribution | 2,200,000 | 4.25% | 92,000 | 100,000 | 200,000 | 164,214.00 |
| Early Stage Deal | 800,000 | 6.50% | 18,000 | 75,000 | 40,000 | 88,560.00 |
Adjusted Sales = Net Sales − Deductible Expenses
Sales-Based Royalty = Adjusted Sales × Royalty Rate
Unit-Based Royalty = Units Sold × Per Unit Royalty
Selected Running Royalty = Higher of Sales-Based Royalty or Unit-Based Royalty
Escalated Royalty = Selected Running Royalty + (Selected Running Royalty × Escalation Rate)
Territory Adjusted Royalty = Escalated Royalty × Territory Multiplier
Sublicense Royalty = Sublicense Income × Sublicense Share
Minimum Top-Up = Higher of 0 or (Minimum Guarantee − Territory Adjusted Royalty)
Gross Before Cap = Territory Adjusted Royalty + Sublicense Royalty + Minimum Top-Up + Upfront Fee + Milestone Payment
Capped Royalty = Lower of Gross Before Cap or Royalty Cap, when a cap exists
Withholding Amount = Capped Royalty × Withholding Tax
Net Payable = Capped Royalty − Withholding Amount
Local Currency Payable = Net Payable × Exchange Rate
Enter the expected net sales and royalty percentage from the license agreement. Add units sold and a per-unit royalty if your contract includes that fallback method.
Provide deductible expenses only if your agreement permits those deductions. Then add minimum guarantees, upfront fees, milestone payments, and any sublicense income share.
Use the territory multiplier when a region carries premium economics. Enter withholding tax and exchange rate to estimate cross-border payment outcomes more realistically.
Set a royalty cap if your deal limits payable amounts. After submitting, review the detailed results, graph, and downloadable summary files.
It estimates running royalties, guarantee top-ups, sublicense shares, fees, withholding deductions, and local currency payable amounts from common licensing terms.
Some agreements use percentage royalties, while others include a per-unit minimum. Comparing both helps reflect whichever method produces the larger contractual payment.
If calculated running royalties fall below the guaranteed minimum, the shortfall becomes an added payment so the licensor still receives the agreed floor.
Use it when certain markets justify adjusted economics, such as premium regions, exclusive territories, or country-specific pricing strength built into negotiations.
No. It supports financial estimation only. Actual royalty obligations depend on definitions, audit clauses, deduction rules, reporting periods, and negotiated contract language.
The tool subtracts withholding tax from the capped royalty total. This helps estimate the net amount remitted after tax deductions.
Enter zero for the cap. The calculator will then use the full gross payable amount without applying any maximum ceiling.
Yes. Change rates, guarantees, fees, and sublicense revenue assumptions to compare deal structures before drafting or revising license terms.
