Coupon Redemption Rate Calculator

Measure the share of issued coupons actually redeemed, the key input to promotion forecasting.

About Coupon Redemption Rate Calculator

The redemption rate is the share of coupons issued that coupons redeemed represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.
