Why this page exists

Cash-generation analysis gets easier to discuss when net income and a few practical owner-earnings adjustments are turned into one estimate instead of being reviewed across several separate line items. This calculator helps visitors estimate owner earnings from net income, non-cash add-backs, maintenance capital spending, and working-capital change using a simplified Buffett-style approach.

Calculator

Owner earnings calculator

Estimate owner earnings from net income, non-cash add-backs, maintenance capital spending, and working-capital change.

Result

$825,000

Estimated owner earnings from net income plus non-cash add-backs, minus maintenance capital spending and any increase in working capital.

Owner earnings$825,000

Values added back$170,000

Values deducted$165,000

Working-capital change used$45,000

$820,000 of net income plus $140,000 of depreciation and amortization and $30,000 of other non-cash charges, minus $120,000 of maintenance capital spending and $45,000 of working-capital change, gives owner earnings near $825,000.
A working-capital increase of $45,000 is treated as a cash use and deducted in this simplified owner-earnings view.
Use the result as a simplified cash-generation estimate only, because maintenance capex, non-cash charges, and working-capital definitions can vary from one analysis to another.

This is a simplified Buffett-style owner-earnings estimate, not financial advice. Definitions of maintenance capital spending, working capital, and non-cash adjustments can vary across analyses.

How it works

What the calculator is doing

Enter net income, depreciation and amortization, and any other non-cash charges you want added back.

Enter maintenance capital expenditures and the change in working capital for the same period.

The calculator adds back the non-cash items, subtracts the capital spending and working-capital use, and shows the resulting owner-earnings estimate.

Understanding your result

This is a simplified owner-earnings estimate, not financial advice. Different analysts may treat maintenance capex, non-cash items, and working-capital changes differently.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Turn accounting profit into a cash-style estimate

Owner earnings can make it easier to discuss cash generation than net income alone.

Compare two reporting periods

Using the same owner-earnings definition across two periods can make changes in cash generation easier to compare.

Use it beside valuation tools

Owner earnings often makes more sense when paired with yield, valuation, and discounting tools.

FAQ

Common questions

How are owner earnings estimated here?

The calculator starts with net income, adds back depreciation, amortization, and other non-cash charges, then subtracts maintenance capital expenditures and the change in working capital.

Why does working-capital change matter?

An increase in working capital uses cash and reduces the estimate here, while a decrease in working capital is treated as a cash release and acts like an add-back.

Is this the same as free cash flow?

Not exactly. Owner-earnings approaches often focus more narrowly on maintenance spending and a simplified set of adjustments, while free-cash-flow definitions can vary.
