Test a small repeat-rate increase
See what could happen if an additional 1% to 30% of customers made one more purchase.
A simple example
A business serves 100 customers per month, with an average purchase of €40. If an additional 5% buy one more time:
100 × 5% × €40 = €200 per month
Estimated additional revenue
€2,400/year
This is an illustrative estimate, not a guarantee. Actual results depend on demand, timing, margins, capacity and execution.

What does “additional repeat purchase rate” mean?
It is the extra percentage of monthly customers you are testing. For example, 5% of 100 customers equals five additional repeat purchases.
Does this calculate profit?
No. RepeatLift estimates potential additional revenue before costs. To estimate profit, subtract product, labour, delivery, payment and other variable costs.
Can any type of business use this calculator?
Yes. It can be used by retailers, salons, makers, florists, groomers, restaurants, e-commerce stores and other businesses with repeat-purchase potential.
Does the calculator store my figures?
No. The calculation runs in your browser and the values are not submitted to RepeatLift.
