Payback Period (PP) Explained

What is Payback Period?

The Payback Period is a capital budgeting metric that calculates the time required to recover the initial investment in a project. It answers the fundamental question:

"How long will it take to get my money back?"

Key Features

  • Simple Metric: Easy to calculate and understand

  • Risk Indicator: Shorter PP = Lower risk

  • Liquidity Focus: Measures capital recovery speed

Calculation Method

For Uneven Cash Flows:

PP = Year before full recovery + (Unrecovered cost at start of year / Cash flow during year)
Example Calculation
Initial Investment: $15,000
Cash Flows:

  • Year 1: $4,000

  • Year 2: $5,000

  • Year 3: $6,000

Calculation Steps:

  1. Year 1: $4,000 (Cumulative: $4,000)

  2. Year 2: $5,000 (Cumulative: $9,000)

  3. Year 3: Need $6,000 → $6,000/$6,000 = 1 year

  4. Total PP = 2 + 1 = 3 years
