Payback period is the time required to recover the cost of an investment from the net cash flows it generates, used to evaluate investment risk and capital allocation.
Formula and example
Payback Period = Initial Investment ÷ Annual Net Return; ROI = (Annual Return × Years - Investment) ÷ Investment × 100
If you invest $10,000 in equipment that saves $3,000/year, payback period is 3.33 years (40 months). Over a 5-year evaluation period, total ROI is 50%.
Methodology & assumptions
Last updated: 2026-06-13Calculation method
Simple payback calculation without discounting (time value of money). For capital-intensive investments, consider using discounted cash flow (DCF) analysis for a more accurate picture.
Data sources

Frequently asked questions
What is a good payback period?+
For small business investments, a payback period under 2 years is generally considered low risk. 2-4 years is moderate, and over 4 years is high risk — the investment should offer other strategic benefits to justify the wait.
How is payback period different from ROI?+
Payback period tells you how long to recover your investment; ROI tells you the total return over the investment's full life. A short payback period with low ROI may be worse than a longer payback with high ROI.
Should I use simple or discounted payback?+
Simple payback (this calculator) is fine for quick comparisons. For larger investments, use discounted payback that accounts for the time value of money — it gives a more accurate picture.
