Payback Period Calculator

About the Payback Period Calculator

The Payback Period Calculator determines the time required for an investment to recover its initial cost through annual cash inflows. This tool is designed for investors, business owners, and financial analysts.

Payback Period: The duration (in years) needed to recoup the initial investment, calculated as \( \frac{\text{Initial Investment}}{\text{Annual Cash Inflow}} \).

Use this calculator to evaluate the risk and liquidity of investments.

• Helpful Tips:
  • Both inputs must be positive numbers (decimals allowed).
  • Assumes uniform annual cash inflows for simplicity.
  • Payback period is rounded to two decimal places for clarity.
  • Does not account for time value of money (use discounted payback period for that).
• Examples:
  • Example 1: Uniform Cash Flow:
    • Initial Investment: $10000
    • Annual Cash Inflow: $3000
    • Steps:
      • Payback Period: \( \frac{10000}{3000} = 3.33 \)
    • Result: Payback Period = 3.33 years
  • Example 2: Decimal Inputs:
    • Initial Investment: $15000.50
    • Annual Cash Inflow: $4000.25
    • Steps:
      • Payback Period: \( \frac{15000.50}{4000.25} = 3.75 \)
    • Result: Payback Period = 3.75 years
