What this calculator measures
Calculates the time required to recover an initial investment amount.
Common use cases
Use this model when the inputs describe the same decision, period and customer or product scope.
- Estimate how long level cash inflows take to recover an initial investment.
- Use the result with the recorded inputs: Initial investment, Annual net cash inflow.
- Compare multiple scenarios before making a finance decision.
Formula
Payback period = Initial investment ÷ Annual net cash inflow
Simple payback ignores discounting and cash flows after recovery.
Worked example
$50,000 initial cost divided by $10,000 annual cash flow equals a 5-year payback period.
How to interpret the result
Shorter payback periods reduce exposure to long-term market risk.
Assumptions and limitations
- Annual cash inflows remain consistent.
