How it works

What the calculator is doing

Enter free cash flow and total revenue for the same period.

The calculator divides free cash flow by revenue.

It shows the resulting free-cash-flow margin percentage and the values used in the estimate.

Understanding your result

This is a simple cash-efficiency metric, not investment advice. The result can become harder to interpret when revenue is low or when 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?

Because free cash flow focuses on cash left after operating and capital needs, while profit margins are based on accounting earnings measures.
