Free cash flow margin calculator

Estimate how much of revenue is turning into free cash flow.

Result

7.90%

Estimated free cash flow margin based on free cash flow divided by total revenue.

Free cash flow margin7.90%

Free cash flow used$980,000

Revenue used$12,400,000

Free cash flow per $100 of revenue$7.90

$980,000 of free cash flow divided by $12,400,000 of revenue gives a margin near 7.90%.
In this simple view, the business is generating about $7.90 of free cash flow for every $100 of revenue.
Use the result as a quick cash-efficiency check only, because capital intensity, seasonality, and one-time cash movements can move the margin materially.

This is a simple cash-efficiency metric, not investment advice. The result can be harder to interpret when revenue is very low or when free cash flow is unusually volatile.

FAQ

Common questions

How is free cash flow margin calculated here?

The calculator divides free cash flow by revenue and shows the result as a percentage.

Can the margin be negative?

Yes. If free cash flow is negative while revenue is positive, the margin will also be negative in this simple calculation.

Why is this different from a profit margin?
