Quick guide
How to use this calculator
- Enter only the market, accounting, cash-flow, rate, or timing assumptions named by the fields.
- Keep currencies, periods, per-share values, and percentage conventions consistent.
- Review the formula and limitations before interpreting or comparing the result.
Calculation method
Calculation method
Growing perpetuity value = next-period cash flow ÷ (discount rate − growth rate).
Fixed decimal inputs and scalar arithmetic remain exact until display. Root and growth calculations are explicitly marked approximate.
Worked example
Worked example
A next-period cash flow of 100, discount rate of 8%, and growth of 3% give a value of 2,000 one period before that cash flow.
Growing perpetuity value = next-period cash flow ÷ (discount rate − growth rate).
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%; narrower domains are validated by the formula.
International scope
No currency, exchange, live security price, accounting standard, tax jurisdiction, market convention, settlement rule, or regulatory disclosure is selected automatically.
Decision boundary
Results are calculations from visitor-entered assumptions, not market data, forecasts, financial advice, suitability assessments, fair-value opinions, or recommendations.
Calculator-specific assumptions
The result is positioned one period before the first entered cash flow. Rates and cash-flow periods must match; taxes, risk changes, and finite-life assumptions are excluded.
