How Coupon Savings Are Calculated
Coupons come in two forms: a percentage off the total, or a fixed dollar amount. This calculator handles both and shows the effective discount rate.
Percentage Coupon
Savings = Cart Total x Coupon % / 100
Fixed Dollar Coupon
Savings = Coupon Dollar Amount
计算示例
You have an $85 cart and a 15% off coupon.
- 01Coupon type: Percentage off
- 02Savings = $85.00 x 15 / 100 = $12.75
- 03Final total = $85.00 - $12.75 = $72.25
- 04Effective discount = 15.0%
常见问题
When is a fixed-dollar coupon better than a percentage coupon?
A fixed-dollar coupon is better when the discount amount exceeds what the percentage would save. For example, $20 off is better than 15% off on a $100 cart ($20 vs $15).
Can I use multiple coupons?
Most retailers allow only one coupon per order. If stacking is allowed, apply the percentage coupon first, then the fixed dollar amount for maximum savings.
Do coupons apply before or after tax?
Coupons reduce the pre-tax subtotal. Sales tax is then calculated on the reduced amount, so you also save a small amount on tax.
