The tools
One tool for each question
Each tool answers a question store owners ask when they set up or review an affiliate program.
Affiliate commission calculator
What commission rate can my margins support?
Works out your break-even rate, the most you can pay while keeping your profit, and a sensible rate to start with.
Discount break-even calculator
How many extra sales does this coupon need to pay for itself?
Shows the sales increase a discount needs before it adds profit, with a reference table for common margins.
Affiliate program ROI calculator
Would an affiliate program make my store money?
Projects 12 months of referred revenue, commission paid, net profit and ROI from assumptions you control.
Coupon code name generator
What should I call this coupon code?
Type a name and get a dozen code ideas in different styles. Click any code to copy it.
Commission calculator
Find a commission rate your margins can support
Enter your average order value, gross margin and affiliate coupon discount. The calculator works out three rates: where you break even, the most you can pay while keeping your minimum profit, and a sensible rate to launch with.
Most commission calculators leave out the coupon discount. This one includes it, because the discount and the commission both come out of the same margin. For the strategy side, see our guide to setting affiliate commission rates in WooCommerce.
- Break-even, maximum and suggested rates
- Includes your affiliate coupon discount
- Worked example showing every step
Break-even calculator
See how many extra sales a discount needs
Discounts cost more than they look. At a 50% margin, a 15% coupon needs about 43% more orders to make the same profit as before.
Enter your margin and a planned discount, and the calculator shows the sales increase you need to break even. Use it before any sale, coupon campaign or affiliate discount.
- Sales increase needed to break even
- Reference table for common margins and discounts
- Works for sales, coupons and affiliate discounts
ROI calculator
Project 12 months of affiliate program profit
Get a 12-month projection of referred revenue, commission paid, net profit and ROI. It includes your gross margin, coupon discounts, the share of affiliates who promote you, and your fixed program costs, so the result is profit, not only revenue.
Use it before launch to test your program design, and again after launch with real figures from your reports. If the projection comes out low, our guide on why affiliate programs fail to make money covers the usual causes.
- Month-by-month projection for a full year
- Counts discounts and fixed costs
- Nine inputs you control
Code name generator
Get coupon code ideas in seconds
Type a name and get a dozen code ideas in different styles: classic codes like EMMA15, evergreen codes like EMMASAVES, and community codes like TEAMEMMA. Click any code to copy it.
The page also covers naming rules that save money, such as avoiding codes that strangers can work out easily, and why near-duplicate codes can credit sales to the wrong affiliate in coupon-tracked programs.

Each tool page explains its formula with a worked example, so you can check the maths or copy it into a spreadsheet.
Nothing is stored
There are no accounts and no email forms. The calculations run in your browser, and your numbers are never sent anywhere.
Questions
Frequently asked questions
Are these tools free?
Yes. There is no cost, no signup and no feature limit. We make a WooCommerce affiliate plugin, and free tools that help store owners get their numbers right are good marketing for it.
Do I need the Coupon Affiliates plugin to use them?
No. The maths works for any affiliate program on any platform. The coupon discount fields start with values typical of coupon-based programs, and setting them to zero makes every calculator work for link-only programs too.
Is anything I enter stored or sent anywhere?
No. Every tool runs in your browser. Nothing you type is saved, logged or sent to us or anyone else.
Can I link to or share these tools?
Yes, please do. You are welcome to reference them in your own articles, courses or resource lists. If you cite a formula, link to the tool page so your readers can check the working.
Where do the formulas come from?
Standard retail and unit economics, applied to affiliate programs. Each tool page explains its formula and shows a worked example with the same defaults the calculator loads with. If you spot an error in the maths, contact us and we will fix it.
