About this digital tool
The payback period calculator shows how long it takes for an investment to recover its initial cost from the cash flows it produces. Enter the initial investment and the net income for each year or month, and the tool adds up the flows until their sum passes the investment, giving the exact time, including the fraction of a period.
It is a simple risk indicator: the shorter the period, the sooner the money comes back. Businesses use it for equipment, solar panels, rental premises or other investments. The limitation is that it does not measure profit after payback and does not discount time, so it should be used together with ROI or IRR. The result is an estimate.
How to use
- Enter the initial investment.
- Add the annual cash flows.
- See after how many periods the investment is recovered.
Frequently asked questions
Is the payback period enough for an investment decision?
Not on its own — it does not measure total profit after payback. Use it with ROI and IRR for the full picture.
How is the payback period calculated?
If the flows are equal, divide the investment by the annual flow. For a 600,000 lek investment and 150,000 lek a year, payback takes 4 years.
What payback period is considered good?
It depends on the type of investment and the risk. In general shorter is better, but always compare with alternatives and with the investment's lifespan.
Why isn't the payback period alone enough?
Because it ignores what happens after payback and does not discount the value of money over time. Two projects with the same period can have very different total profit.
