Cash flow to debt calculator
Operating cash flow of 200,000 against total debt of 1,000,000 gives a cash flow to debt ratio of 0.2, so one period of cash from operations covers a fifth of the debt. See the decimal and the percent side by side. Free in your browser.

This cash flow to debt calculator measures solvency by dividing a company's operating cash flow by its total debt. The resulting ratio shows how much of the outstanding debt book one period of cash from operations could theoretically cover: a ratio of 0.20 means twenty percent of total debt is matched by the period's operating cash flow, while a ratio of 0.50 means half the book. Enter both amounts in the same currency, and the engine returns the decimal ratio, the same figure as a percent, and the formula used. Operating cash flow may be zero or negative to model a cash-burning period; total debt must be strictly positive because a zero or negative denominator is undefined.
What the cash flow to debt ratio measures and how it is computed
The cash flow to debt ratio answers a solvency question that earnings-based coverage ratios do not: given the cash the firm actually generated from operations, what share of the entire debt book could that cash theoretically retire in one period. Operating cash flow is the cash-flow-statement line often labelled cash from operating activities or CFO — net income adjusted for non-cash items and working-capital movements — not EBIT and not free cash flow after capex.
Total debt is the stock of interest-bearing obligations at the same date: short-term borrowings, the current portion of long-term debt, bonds, notes, and similar contractual principal, in the same currency as the cash-flow figure. Worked example: operating cash flow of 200,000 against total debt of 1,000,000 yields a ratio of 0.2 and a percent of 20, meaning one period of CFO covers a fifth of the book. Another example: cash flow of 450,000 and debt of 900,000 yields 0.5, or fifty percent.
A ratio of 1.0 means operating cash flow equals the entire debt stock; values above 1.0 mean one period of CFO exceeds the book. Unlike the interest coverage ratio, which divides operating income by period interest, and unlike DSCR, which divides net operating income by principal-plus-interest debt service, this page divides cash from operations by the stock of total debt.
That is a different search and a different credit question: not “can we pay this period’s coupon or instalment,” but “how large is the debt pile relative to the cash operations actually produce.”
Where cash flow to debt fits in credit analysis and automation
Lenders, bond analysts, and corporate treasurers use cash flow to debt to screen issuers, compare peers, and stress whether a drop in operating cash flow would leave the firm sitting on a debt book it cannot organically shrink. Rating methodologies and credit memos often quote the ratio as a percent and treat a rising figure as stronger coverage of the stock of debt, while a falling or negative figure flags cash burn against an unchanged (or growing) book.
Students and CFA candidates meet the same identity when a textbook asks how many times, or what fraction of, total debt operating cash flow represents without building a full debt-service schedule. If you need period debt-service coverage including principal amortization, use a DSCR tool; if you need earnings over interest only, use interest coverage. This page answers only operating cash flow over total debt, with stable, reproducible output and no market data.
What you can do with it
Issuer and borrower solvency screens
Divide reported operating cash flow by total debt to see what share of the debt book one period of CFO could theoretically cover before a credit committee or peer review.
Teaching and exam practice
Generate reproducible cash-flow-to-debt answers for homework keys, worksheets, and CFA-style solvency drills that ask for CFO divided by total debt.
FAQ
Can operating cash flow be negative?
Yes. A cash-burning period is allowed and produces a negative ratio, which is a solvency signal rather than a validation error.
How is this different from DSCR or interest coverage?
DSCR divides net operating income by period debt service (principal and interest). Interest coverage divides operating income by interest expense. Cash flow to debt divides operating cash flow by the stock of total debt — different metric, different search intent.
What does the calculator cost?
It is free in your browser on this page.
What counts as operating cash flow here?
The cash from operating activities line of the cash flow statement: net income adjusted for non-cash items and working-capital movements. It is not operating profit, and it is not the cash left over after capital spending.
What should total debt include?
The interest-bearing obligations at the same date: short-term borrowings, the current portion of long-term debt, bonds, notes and similar contractual principal. Use the same currency and reporting window as the cash flow figure.

Technical notes
The work is pure deterministic arithmetic with no market feed, no network call, and no date shortcut, so the same inputs always produce the same JSON.
What the cash flow to debt ratio measures and how it is computed
The identity used here is cash_flow_to_debt equals operating_cash_flow divided by total_debt.
Inputs, validation, rounding, and reading the result
Operating cash flow may be zero or negative so a cash-burning period produces a zero or negative ratio rather than a silent refusal; that negative figure is a real solvency signal, not a form error. There is no clock, locale, or randomness in the path. Prefer bare numbers over formatted strings; currency marks, thousands separators, and trailing unit labels are not parsed. Both operating_cash_flow and total_debt are required finite numbers in the same currency and the same reporting window. Total debt must be strictly greater than zero: a zero or negative debt amount returns a typed invalid_input error that names the field, because dividing by it is undefined or meaningless for a coverage-of-the-book ratio. Optional aliases ocf, cash_flow, cfo, and operating_cf map to operating_cash_flow; debt maps to total_debt so a spreadsheet export or form client can reuse familiar labels. On success the body echoes the rounded inputs, returns cash_flow_to_debt as the raw quotient, repeats that figure as cash_flow_to_debt_percent (the quotient times one hundred) so a dashboard can bind either a decimal or a percent, and includes a formula string set to cash_flow_to_debt = operating_cash_flow / total_debt. Failed validation is never billed; only successful API tasks consume prepaid balance at the published base rate of $0.002.

Technical questions
What is the cash flow to debt ratio formula?
cash_flow_to_debt = operating_cash_flow / total_debt. The tool also returns cash_flow_to_debt_percent, which is that quotient times one hundred.
Why must total debt be greater than zero?
The ratio divides operating cash flow by total debt, so a zero or negative total_debt is undefined and returns invalid_input. The request is not billed.
