Earnings to free cash flow
Earnings to free cash flowNoncash adjustments, working capital, and capital expenditure reconcile earnings to cash.
Cash generation under working-capital pressureWorking-capital investment is horizontal; operating and free cash flow remain separate so the additional capital-expenditure step is visible.

- Deduct capital expenditure using the same sign convention.
- Reconcile unusual movements before interpreting the conversion percentages.
Calculator guide
Understanding Cash Conversion Efficiency Calculator
Cash conversion efficiency explains how reported earnings translate into free cash flow. Noncash adjustments, working-capital movement, and capital expenditure remain separate so a strong ratio cannot hide the source of cash.
Calculation method
How the calculation works
Reconcile net income to a simplified operating cash-flow estimate and compare both operating and free cash flow with earnings. Noncash charges are added to net income and the entered working-capital increase is deducted to calculate operating cash flow. Capital expenditure is then deducted for free cash flow; both cash measures are divided by net income for conversion ratios.
Cash-quality review
Identify what drove the conversion result
The ratio is useful only after the cash source is classified.
Worked situations
Practical examples
- Receivables growth can reduce operating cash flow despite positive earnings.
- Large depreciation may lift operating cash flow but does not eliminate asset-replacement needs.
- A one-time inventory release can temporarily produce conversion above 100%.
Better inputs
Useful tips
- Use cash-flow-statement classifications consistently.
- Separate maintenance and growth capital expenditure when decision-making requires it.
- Review several periods to identify timing reversals.
Before relying on the result
Limitations and common mistakes
- The simplified bridge excludes many operating-cash-flow adjustments.
- Acquisitions, leases, factoring, securitization, taxes, and discontinued operations may require separate treatment.
- A high conversion ratio does not by itself prove sustainable cash generation.

Frequently asked questions
Can cash conversion exceed 100%?
Yes, for example after working-capital release or large noncash charges; investigate whether it is repeatable.
Why deduct capital expenditure?
It converts operating cash flow into a simplified free-cash-flow measure.
What if net income is zero or negative?
Conversion ratios become undefined or hard to interpret; use the cash bridge amounts directly.
Is working-capital change always a cash use?
No. This input is specifically labeled as an increase; a release should be entered with the opposite sign.
