How to Calculate Payback Period for Investments

To calculate the payback period, divide your initial investment by the annual cash inflow for even cash flows. For uneven cash flows, add each year's inflow until the total equals or exceeds the investment. The year in which this happens is your payback period.

Payback Period: Even vs Uneven Cash Flows Explained

The payback period method is a simple way to evaluate investments. Even cash flows make calculation easy, while uneven flows require a year-by-year approach. Use this tool to compare both scenarios and make informed decisions.

  • Even Cash Flows
    Same inflow every year. Simple division gives the payback period.
  • Uneven Cash Flows
    Varying inflows require cumulative calculation and a table.
  • Business Use Cases
    Compare projects, plan investments, and assess risk with payback period analysis.
