Introduction

Payback period is how long it takes cumulative cash inflows to recover the initial investment. Simple payback ignores the time value of money; discounted payback uses a discount rate for a stricter test.

What Is Payback Period?

Payback period is how long it takes cumulative cash inflows to recover the initial investment. Simple payback ignores the time value of money; discounted payback uses a discount rate for a stricter test.

When to Use It

Payback is popular for quick screening when liquidity matters—small businesses, capital budgets with tight cash constraints, or equipment with uncertain long life.

Strengths and Weaknesses

  • Pro: easy to explain to non-finance stakeholders.
  • Pro: highlights liquidity risk.
  • Con: ignores cash flows after payback.
  • Con: simple payback ignores discount rates.

Pair with IRR and NPV

Use payback as a first filter, then run IRR and NPV-style analysis for finalists. Long-lived projects may be attractive on IRR while payback looks slow.

Formula

Future Value with compounding: FV = P(1 + r/n)^(nt). For periodic deposits, each contribution grows from its deposit date at the same periodic rate.
