Coupon Affiliate Attribution Calculator
They were already in the basket.
Paid on sales you already had
$16,347
336 genuinely new orders
Someone opening a new tab to search for a code was already buying. Paying commission and a discount on that order costs $16,347 for nothing — and the true cost per new customer is $67.57, not the headline commission rate.
How the Coupon Affiliate Attribution Calculator works
Someone who opens a new tab to search for a discount code was already buying. Paying commission and a discount on that order is money for nothing — and the true cost per genuinely new customer is a large multiple of the headline commission rate.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
Why do coupon sites get so much credit?
Because last-click attribution rewards whoever touched the customer most recently, and searching for a code is the last thing many buyers do before checkout.
How do I measure the leakage?
Look at how many code-using orders had already reached the cart or checkout before the affiliate click. Most analytics can show that sequence, and the answer is usually uncomfortable.
Should I block coupon affiliates?
Consider reduced rates rather than exclusion — they also intercept customers who would otherwise leave to find a code elsewhere and not return. The right rate is far below content affiliates.
What about an on-site code field?
An empty code field prompts the search that starts the leakage. Hiding it behind a link, or removing it where you do not run codes, reduces the behaviour at source.
