Frequently asked questions about the calculator

What does the loyalty ROI calculator measure?

It estimates the additional annual revenue that could result from more repeat sales and a higher average order value.

How is the result calculated?

We start with monthly sales and average order value, then calculate the annual difference using 50% more repeat sales and a 30% higher average order value.

Is this estimate profit?

No. It is estimated revenue uplift. Profit also depends on your margin, rewards, taxes and operating costs.

Why does the calculator use these two uplift assumptions?

They provide a simple, easy-to-understand scenario. They are not a guarantee: actual growth varies from one business to another.

Does STMPR save the numbers I enter?

No. The calculation runs locally in your browser and the values are not sent to STMPR.
