fin.discounted-payback-period Calculator
Calculates discounted payback period by applying a hurdle rate to each year's cash flow before accumulation. The discounted payback period is always longer than the simple payback — projects that look like quick wins may still take years to break even in present value terms.
Inputs
Initial Investment
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.
Annual Cash Flow
Total net cash received or paid in one year. Used in payback period and simple ROI calculations.
Discount Rate Pct
Rate used to bring future cash flows back to today's value. Higher rates make future money worth less — used in NPV, bond pricing, and valuation.
Project Life Years
Reference formula or conversion factor shown for context.
Results
discounted payback period (years)
Time to recover the initial investment from cumulative cash flows. Most firms target 2–5 years. Does not account for the time value of money — use discounted payback for rigour.
NPV at end of life
The value at the specified point or condition.
undiscounted payback
Total number of items or occurrences.
total discounted CF
The combined total across all inputs and components.
