fin.payback-period Calculator
Calculates both simple and discounted payback periods from initial investment and projected annual cash flows. Discounted payback applies a hurdle rate — a project that breaks even in 3 years on a simple basis may take 5+ years in discounted terms.
Inputs
Initial
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.
Cash Yr
Reference formula or conversion factor shown for context.
Disc Rate
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.
Yrs
Reference formula or conversion factor shown for context.
Results
