The Mathematical Formula & Variables

Payback Period = Initial Investment / Annual Cash Inflow

Step-by-Step Worked Example

Scenario: $50,000 project returning $15,000 per year.

  1. $50,000 / $15,000 = 3.333 years.
  2. 0.333 years * 12 months = 4 months.

Result: 3 Years, 4 Months

Frequently Asked Questions

What is the limitation of the simple payback period?

It ignores the Time Value of Money and completely ignores cash flows generated after the payback cutoff point.
