Reward calculator
The numbers to settle before you launch: is your reward generous enough to matter and cheap enough to afford?
Sales price minus what the product costs you to make or buy.

Rewards are costed at what they cost you to make (sales price minus margin), not at their sales price. Break-even is the visit lift at which the programme pays for itself, rewards and subscription included.

How the reward is costed
A free coffee does not cost you its menu price. It costs the beans, milk and cup, which is the sales price minus your gross margin. That is why a 4.50 reward at 70 % margin costs 1.35 to give, and why stamp programmes are cheaper to run than most owners expect.
The one number to get right
Everything depends on the visit lift: how much more often card holders return. The calculator starts from the same illustrative 6 % scenario as our pricing page; published loyalty studies report anything from a few percent to over 30 %, and your first three months will tell you where you sit. Compare with the break-even figure: if the programme breaks even at 4 % lift and you see 8 %, it pays.
Choosing stamps and reward together
The share the reward represents of the spend needed to earn it is what customers feel. Under 5 % and the card is ignored; over 15 % and you are giving away margin you may not need to. Move the stamp count and reward value until the share sits between 5 and 15 %, then check the monthly net.
One stamp per visit, or per amount?
Stamp per visit is simple and rewards frequency, which is what a café or salon wants. Stamp per amount spent suits shops with a wide range of ticket sizes. This calculator assumes one stamp per visit; if you stamp per amount, set the average purchase to the amount one stamp represents.
