About Payback Period Calculator

The payback period is the time required to recover the cost of an investment. It is calculated by dividing the initial investment by the annual cash inflow. The shorter the payback period, the more attractive the investment is considered to be.

How to Calculate Payback Period

To calculate the payback period:

  1. Determine the initial investment amount
  2. Estimate the annual cash inflows
  3. Divide the initial investment by the annual cash inflow to get the payback period in years

Discounted Payback Period

The discounted payback period accounts for the time value of money by discounting the cash inflows. This provides a more accurate measure of how long it takes to recover the investment in present value terms.

Limitations of Payback Period

While simple to calculate, the payback period has limitations:
