Enter Cash Flows
Input the expected annual cash flows as comma-separated values (e.g., "2000, 3000, 4000, 5000"). Enter cash flows for each year in order.
Calculate
Click calculate to see the payback period, which shows how long it takes to recover the initial investment.
Review Results
Use the payback period to evaluate investment risk, compare projects, and make investment decisions.
Formula
Payback Period:
The payback period is the time it takes for cumulative cash flows to equal or exceed the initial investment.
Payback Period = Year when Cumulative Cash Flows ≥ Initial Investment
Cumulative Cash Flow:
Cumulative Cash Flow = Sum of Cash Flows up to Year N
Example: Equipment Investment
Initial Investment: $10,000, Cash Flows: $2,000, $3,000, $4,000, $5,000
Year 1: Cumulative = $2,000 (not recovered)
Year 2: Cumulative = $2,000 + $3,000 = $5,000 (not recovered)
Year 3: Cumulative = $5,000 + $4,000 = $9,000 (not recovered)
Year 4: Cumulative = $9,000 + $5,000 = $14,000 (recovered!)
Payback Period: 3 + (($10,000 - $9,000) / $5,000) = 3.2 years

Frequently Asked Questions
What is payback period?
Payback period is the time it takes for an investment to recover its initial cost through cash flows. It's the number of years (or periods) until cumulative cash flows equal or exceed the initial investment. Shorter payback periods indicate faster recovery and generally lower risk.
What's a good payback period?
Good payback period depends on your industry and risk tolerance. Generally, payback periods of 3-5 years are considered acceptable for most investments. However, technology investments might have longer paybacks, while quick-return projects might have paybacks under 2 years. Compare to your company's investment criteria.
What are the limitations of payback period?
Payback period ignores: time value of money (discounting), cash flows after payback, profitability, and risk. It's a simple screening tool but shouldn't be the only metric. Use with NPV, IRR, and profitability index for comprehensive analysis.
Should I use discounted payback period?
Discounted payback period accounts for time value of money and is more accurate. However, it's more complex. Simple payback is useful for quick screening, while discounted payback provides more accurate analysis. Use simple payback for quick decisions, discounted for detailed analysis.
What if cash flows are negative in some years?
If cash flows are negative, enter them as negative numbers (e.g., "-1000, 2000, 3000"). The calculator will subtract negative cash flows from cumulative totals. This is common for projects with initial operating losses or additional investments required.
Can payback period exceed the cash flow period?
Yes, if cumulative cash flows never reach the initial investment within the entered periods, the investment doesn't pay back. This indicates the investment may not be viable or requires longer time horizons. Consider extending the analysis period or re-evaluating the investment.
