Discounted payback: Estimate when discounted level cash inflows recover an initial investment.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Discounted payback to answer this question: estimate when discounted level cash inflows recover an initial investment? Enter Initial investment, Annual net cash inflow, Annual discount rate, and 1 other input; the calculator shows Discounted payback period. Try changing one number and watch what happens to Discounted payback period. The answer tells you Discounted payback period.
Age 15Explain it to a 15-year-oldConnect it to the formula
Discounted payback recognises the time value of money but ignores cash flows after recovery. Use NPV alongside it for the complete value comparison. The rule is Discount each annual cash flow, then accumulate until present value equals the investment. Its input values are Initial investment, Annual net cash inflow, Annual discount rate (%), Analysis horizon, and the main result is Discounted payback period. Try changing one number and watch what happens to Discounted payback period.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Discount each annual cash flow, then accumulate until present value equals the investment, evaluated from Initial investment, Annual net cash inflow, Annual discount rate (%), Analysis horizon to produce Discounted payback period. Discounted payback recognises the time value of money but ignores cash flows after recovery. Use NPV alongside it for the complete value comparison. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Estimate when discounted level cash inflows recover an initial investment.
Why the business model works
Discounted payback recognises the time value of money but ignores cash flows after recovery. Use NPV alongside it for the complete value comparison.
Inputs and operating assumptions
This model uses Initial investment (at least 0), Annual net cash inflow (at least 0.01), Annual discount rate (at least 0), Analysis horizon (at least 1). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Discount each annual cash flow, then accumulate until present value equals the investment
What the calculator produces
The primary output is Discounted payback period; it also exposes Present value recovered in horizon, Unrecovered investment. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
