What is Payback Period?
The payback period is the time it takes for an investment to recoup its initial cost from its cumulative cash flows. It answers the simple question: "How long until I get my money back?"
Formula
Payback Period = Initial Investment / Annual Cash Flow (if cash flows are uniform)
Example
| Year | Cash Flow | Cumulative |
|---|---|---|
| 0 | -$50,000 | -$50,000 |
| 1 | $15,000 | -$35,000 |
| 2 | $15,000 | -$20,000 |
| 3 | $15,000 | -$5,000 |
| 4 | $15,000 | $10,000 โ payback between year 3-4 |
Payback = 3 + ($5,000/$15,000) = 3.33 years
