# Know what you’ll actually save

Enter the terms of a coupon to estimate the discount. Use the same currency for every amount. This tool does not confirm merchant eligibility.

## What the estimate includes

Percentage savings apply to your eligible subtotal, limited by the cap you enter. Fees are added after that calculation. For later credit, the current payable amount is not reduced. Taxes are included only if you include them in your input; merchant rules may differ.

<p>This calculator needs JavaScript. Formula: saving = the smaller of eligible subtotal × percentage ÷ 100 and the cap, provided the minimum is met.</p>
