Extra revenue from upsell/cross-sell rates. The Upsell Revenue Calculator takes customers per month, upsell take rate, average upsell value, cross-sell take rate, average cross-sell value and returns extra revenue per month plus upsell revenue, cross-sell revenue, extra revenue per customer, extra revenue per year. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Pricing and sales metrics decide how much of the value you create you actually keep. Test price changes against margin, not volume alone, and measure the pipeline consistently so forecasts can be trusted. Use the worked example below to check the maths against your own figures.
How the Upsell Revenue Calculator works
Selling more to existing customers is the cheapest revenue there is. Even modest take rates add up across a customer base; the per-customer figure is what an offer at checkout is worth.
Worked example
With the example values (customers per month of 1000, upsell take rate of 15%, average upsell value of $40, cross-sell take rate of 10%, average cross-sell value of $25), the extra revenue per month is $8,500.00; upsell revenue $6,000.00, cross-sell revenue $2,500.00, extra revenue per customer $8.50, extra revenue per year $102,000.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is extra revenue per month calculated?
extra revenue = customers × (upsell rate × upsell value + cross-sell rate × cross-sell value).
Which figures do I need?
Customers per month, upsell take rate, average upsell value, cross-sell take rate, average cross-sell value. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Should I test a price change before rolling it out?
Yes. Model the margin impact here first, then test on a segment or product line and measure volume and margin before applying it everywhere.
