Formula / Working

The payback period is calculated using the following formulas:

1. For Equal Cash Inflows: Payback Period=Initial InvestmentAnnual Cash Inflow\text{Payback Period} = \frac{\text{Initial Investment}}{\text{Annual Cash Inflow}}Payback Period=Annual Cash InflowInitial Investment​

2. For Unequal Cash Inflows:

• Add yearly cash inflows cumulatively until the total equals the initial investment.
• Payback Period = Last full year + Remaining InvestmentCash Inflow of Next Year\frac{\text{Remaining Investment}}{\text{Cash Inflow of Next Year}}Cash Inflow of Next YearRemaining Investment​

This formula helps calculate how quickly an investment pays back its initial cost.

Examples

Example 1: Equal Cash Inflows

• Initial Investment: $50,000
• Annual Cash Inflow: $10,000

Result: Payback Period = 50,000 ÷ 10,000 = 5 years

Example 2: Unequal Cash Inflows

• Initial Investment: $30,000
• Year 1 Cash Inflow: $8,000
• Year 2 Cash Inflow: $10,000
• Year 3 Cash Inflow: $12,000

Result:

• Cumulative inflow by Year 2 = $18,000
• Remaining Investment = $30,000 – $18,000 = $12,000
• Payback Period = 2 + 12,000 ÷ 12,000 = 3 years

Example 3: Short-Term Project

• Initial Investment: $20,000
• Monthly Cash Inflow: $2,500

Result: Payback Period = 20,000 ÷ 2,500 = 8 months
