Free tools

Do the math before you sign the deal.

Three free calculators that expose what affiliate contracts actually pay. Your inputs, transparent formulas, no signup required. Illustrative math only, never a projection of earnings.

Free, and built to stay honest

No gate, no bait

No signup, no email capture, no unlock steps. Open the tool, get the answer, leave if you want.

Formulas in plain sight

Every tool explains its math on the page. If a result surprises you, you can trace exactly why.

Math, never promises

These are deal-shape comparisons on your own inputs. They are not projections, and nothing here implies earnings.

Questions, answered

Do I need an account to use the tools?

No. The calculators are free, ungated and unlimited. No signup, no email, no watermarked exports.

Are the results projections of my earnings?

No. They are illustrative math on the numbers you type in, built to compare deal shapes. Real results depend on your traffic, your terms and your execution, and nothing here is guaranteed.

Where do the formulas come from?

From the standard mechanics of affiliate agreements: CPA per validated FTD, RevShare on NGR, deductions before the split, carryover of negative balances. Each tool documents its exact assumptions, and your own agreement always prevails.

Will there be more tools?

Yes, this set grows with what affiliates ask for. If a piece of deal math deserves a calculator, tell us through the contact page.
