How to Measure Discount ROI"},"content":{"rendered":"\n

Coupons always look like they work. Orders with the code go up, the campaign gets marked a success, and the code goes into the next newsletter. What the report rarely shows is how many of those customers would have bought anyway \u2014 at full price.<\/p>\n\n\n\n

Discounts are one of the most powerful tools in WooCommerce and one of the easiest ways to lose margin without noticing. Here’s how to tell which is which.<\/p>\n\n\n\n

The Hidden Cost of a Coupon<\/h2>\n\n\n\n

A 20% code doesn’t cost you 20% of the orders it creates. It costs you 20% of every order it touches \u2014 including all the customers who were already on their way to checkout and simply searched for a code first. That’s why the question isn’t “how many orders used the coupon?” but “how many orders did the coupon create?”<\/p>\n\n\n\n

Five Numbers That Show Whether a Coupon Pays Off<\/h2>\n\n\n\n
    \n
  1. Discount share of gross sales.<\/strong> Total discounts divided by gross sales. Track it monthly \u2014 if it creeps up while net sales stay flat, discounts are replacing full-price sales rather than adding to them.<\/li>\n\n\n
  2. Revenue collected per redemption.<\/strong> What customers actually paid on orders using the code, compared with your normal average order value.<\/li>\n\n\n
  3. New vs returning customers.<\/strong> A code meant to win new customers that’s mostly redeemed by existing ones is just a loyalty discount you didn’t plan to give.<\/li>\n\n\n
  4. Repeat rate of coupon-acquired customers.<\/strong> Do customers who arrived through the code ever buy again at full price? If not, the code bought orders, not customers.<\/li>\n\n\n
  5. Free orders.<\/strong> Orders fully paid with coupons or store credit are worth watching on their own \u2014 a sudden rise can point to a leaked code or a stacking loophole.<\/li>\n<\/ol>\n\n\n\n

    A Quick Worked Example<\/h2>\n\n\n\n

    Say a 20%-off code was used on 200 orders in a month, with an average order of \u00a360 before the discount. That’s \u00a32,400 given away. If 120 of those 200 customers were returning buyers who order every month anyway, roughly \u00a31,440 of the discount went to people who’d have paid full price. The code still might be worth it \u2014 but only if the other 80 customers come back, and that’s what the repeat-rate number tells you.<\/p>\n\n\n\n
