Coupon or free shipping: compare the actual savings
A percentage coupon often looks more valuable, but the winner depends on your cart total and delivery fee. This calculator converts both offers into dollar savings so you can choose the larger discount without guessing.

A clearer way to compare.
Coupon saving = cart total × coupon percentage. Free-shipping saving = shipping charge. The offer with the larger saving produces the lower checkout cost.
On a $120 cart, 15% off saves $18. If shipping costs $12, the coupon wins by $6.
Coupon vs Free Shipping FAQ
How accurate is this calculator?
The arithmetic is exact for the values you enter. The practical result depends on whether those prices, quantities, and assumptions match your purchase.
Are taxes included?
Use tax-inclusive prices when tax differs between your options. Otherwise, the comparison remains useful before tax.
Can I use euros, pounds, or another currency?
Yes. Keep every money input in the same currency. The comparison and percentages remain valid even when the displayed symbol differs.
Is any information stored?
No. The calculation runs entirely in your browser and is not sent to a database.
