Quick guide
How to use this calculator
- Gather Maintainable seller's discretionary earnings, and Entered SDE multiple for the same business scenario before calculating.
- Keep pre-money and post-money values, cash and non-cash expenses, current and fully diluted ownership, and one-time versus recurring flows distinct.
- Apply the displayed sde business valuation result to the stated decision only after checking every entered assumption.
Calculation method
Calculation method
Indicative SDE-based value = Maintainable seller's discretionary earnings × Entered SDE multiple.
The calculation uses these named inputs: Maintainable seller's discretionary earnings, and Entered SDE multiple. No market rate, benchmark, tax rule, or accounting classification is inserted automatically.
Fixed-decimal arithmetic remains exact through display unless a result is explicitly labelled approximate, such as a square-root inventory quantity.
Startup runway and fundraising
Where the SDE Business Valuation Calculator helps
Estimate an indicative small-business value from SDE and an entered multiple.
Use the result to make an entered cash, burn, dilution, valuation, or fundraising scenario explicit for discussion.
- Prepare a board cash scenario
- Compare financing terms on the same capitalization basis
- Test how hiring or revenue timing changes runway
Interpretation check
How to audit the result
Recalculate the scenario when any of these inputs changes: Maintainable seller's discretionary earnings, and Entered SDE multiple.
Keep this formula beside the result: Indicative SDE-based value = Maintainable seller's discretionary earnings × Entered SDE multiple. Then compare the output with the source records and the calculator-specific assumption below.
- Confirm that all amounts use one currency and reporting period.
- Check that rates, counts, and quantities describe the same population or transaction set.
- Save the entered assumptions with the decision; the result alone is not reproducible evidence.
Worked example
Worked example
Using maintainable seller's discretionary earnings of 200 and entered sde multiple of 5 gives 1,000.00.
Indicative SDE-based value = Maintainable seller's discretionary earnings × Entered SDE multiple.
Supported inputs
Precision and limits
Visible input limits
Fixed decimals accept up to 30 digits and 12 decimal places and are capped at an absolute value of 1e12 per input. Rates are capped at 1000%; percentage shares and method-specific domains may be narrower.
International scope
No currency, tax jurisdiction, accounting framework, payroll rule, marketplace fee schedule, financing term, or industry benchmark is selected automatically.
Decision boundary
Use the result to make an entered cash, burn, dilution, valuation, or fundraising scenario explicit for discussion. Results remain arithmetic scenarios, not accounting records, forecasts, valuations, legal interpretations, professional advice, or recommendations.
Calculator-specific assumptions
The entered multiple and maintainable SDE require independent due diligence. The output is not a valuation opinion.
