About the Payback Period Calculator
The payback period is the length of time required for an investment’s cash flows to recover its initial cost. It’s one of the simplest capital budgeting tools, popular for its intuitive interpretation as a "breakeven time" measure.
Simple vs. Discounted Payback
The simple payback period sums raw cash flows until they equal the initial investment. The discounted payback period first discounts each cash flow back to present value using your chosen rate, which better reflects the true time value of money and typically results in a longer payback period.
Limitations
Payback period ignores cash flows that occur after the recovery point, so it doesn’t measure overall profitability. Two investments with the same payback period can have very different total returns. Use payback period as a liquidity/risk screening tool alongside NPV and IRR, not as your sole investment criterion.
