A payback period calculator determines how long it takes to recover the initial cost of an investment from its cash flows.
About this calculator
A payback period calculator determines how long it takes to recover the initial cost of an investment from its cash flows. It is a simple capital budgeting metric that shows how quickly an investment pays for itself.
While payback period does not account for the time value of money, it is a useful first filter for investment decisions, shorter payback periods reduce risk by recovering capital faster.
Common uses
- Determine how quickly a business investment recovers its cost
- Compare two projects by their payback periods
- Assess risk by identifying how long capital is exposed
- Screen capital expenditure proposals
Frequently asked questions
What is a good payback period?
It depends on the industry and risk level. For low-risk infrastructure projects, 5–10 years may be acceptable. For technology investments, 1–3 years is typical. For most business investments, a payback period under 5 years is generally considered favourable.
What are the limitations of the payback period?
Payback period ignores the time value of money, ignores cash flows after the payback date, and does not measure profitability. A project with a 3-year payback that earns nothing after year 3 may be worse than one with a 5-year payback that earns strongly afterward. Always complement payback analysis with NPV or IRR.
