Payback Period Calculator
Calculate how long it takes an investment or project to pay for itself from its incoming cash flows.
Payback period
3.33 years
What Your Result Means
Payback period is how many years it takes for cumulative cash flows to recover your initial investment. A shorter payback period generally means lower risk, since your capital is tied up for less time.
How It Is Calculated
Track cumulative cash flow each year until it crosses zero; interpolate within that year for a fractional payback period.
Worked Example
A $40,000 investment returning $12,000/year reaches a cumulative positive balance partway through year 4 - a payback period of roughly 3.3 years.
Important Assumptions
- Payback period doesn't account for the time value of money - it treats a dollar received in year 5 the same as a dollar received today. Consider IRR or NPV for a more complete picture.
- Doesn't account for cash flows after the payback point, so it can favor short-term projects over more profitable long-term ones.
Frequently Asked Questions
- What's a good payback period?
- This varies by industry - many businesses target 2-3 years for a project to be considered attractive, but capital-intensive industries often accept longer payback periods.
- What if the investment never pays back?
- If cumulative cash flows never turn positive within the years you've entered, the calculator will show 'Not recovered' - try adding more years or reconsidering the investment.
