Understanding Incomplete Payback
What does incomplete payback mean?
When your results show "incomplete payback", it means your projected cash flows don't fully recover the initial investment amount within the specified time period.
Common Causes:
- Underestimated cash flows - Projections may be too conservative
- Timeframe too short - Investment may pay back with more time
- Overestimated benefits - Expected savings/revenues may not materialize
- High initial costs - Upfront investment may be too large
How to Improve:
Adjust Projections
- • Extend the time horizon
- • Increase expected cash flows
- • Add more years of projections
Modify Investment
- • Reduce initial costs
- • Phase implementation
- • Find cost-saving alternatives
When to Reconsider:
If payback remains incomplete even after adjusting projections, the investment may not be viable. Consider whether:
- The strategic value justifies the long payback
- Alternative investments offer better returns
- Your business can sustain the cash flow requirements
Payback Period Formulas
Simple Payback Period
When cash flows are equal each year:
Payback Period = Initial Investment ÷ Annual Cash Inflow
Example: $10,000 investment with $2,500 annual return = 4 years payback
Discounted Payback Period
Accounts for time value of money:
Discounted Cash Flow = Cash Flow ÷ (1 + r)n
Where r = discount rate, n = year number
More accurate but more complex to calculate than simple payback
