Three free calculators that do the loyalty card arithmetic before you launch: reward cost, which shows the gap between headline give-back and true cost; the right stamp count for your customer’s frequency; and the annual cost of paper cards. All three run inside your browser with no sign-up and no numbers sent to a server.
Reward cost calculator: perceived give-back vs true cost
Enter average ticket, margin and stamp count to see what your customer feels they won and what every reward truly costs you — before you announce it.
how many stamps before the rewardHow many stamps before the reward? Pick the number from your data
The right stamp count comes from how often your customer visits, not taste. Enter visits per month and get the number that finishes before interest fades.
cost of paper punch cardsWhat do paper cards cost you in a year?
Printing isn't the real cost — loss is. Enter monthly volume and print cost to see how many customers drop out each year with a forgotten card.
Why calculate before launching?
Because two decisions in a loyalty card are hard to reverse afterwards: the stamp count and the reward value. Lowering either later feels to the customer like something promised was taken back, and raising either costs you margin you did not plan for. Ten minutes with these calculators saves you an awkward correction three months in.
And the calculators give you your number, not a generic one lifted from someone else’s shop. Every calculation runs inside your browser as you type: no sign-up, no waiting, and not one of your shop’s numbers leaves this page.
