Reward and cashback calculator
Try different stamp targets or cashback rates and calculate the reward cost relative to the purchases that earn it. No registration: your figures are calculated in this browser.
Define your example
Use a consistent tax basis for all amounts. Margin is the percentage of sales left after direct product or service costs, before rewards and fixed expenses. Enter what the reward costs you, not its selling price.
Your simulation
This is a simulation, not a profit forecast. It assumes the full reward is redeemed and excludes subscription fees, staffing, rent and other fixed expenses. It does not estimate additional sales or changes in customer behaviour.
Set up your programmeHow to interpret the calculation
For stamps, we multiply the purchase amount by the required number of purchases. We apply your margin and subtract the cost of providing the reward. For cashback, we calculate the credit percentage on one purchase and subtract it from that sale’s contribution. Monetary amounts are rounded to cents.
Compare scenarios under the same conditions. If you change the product, its cost or the average purchase amount, update the margin as well. An appealing reward needs clear terms and a cost your business can support.
