PUTTING IT INTO PRACTICE
Inflation Linked Payment: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| First annual payment | 1,000 |
| Annual escalation (%) | 3 |
| Payment number (integer) | 3 |
| Result | 1,060.9 currency units |
- Check the input labels and enter the example values above.
- Apply the relationship: Payment n = first payment × (1+escalation)^(n−1).
- The result is 1,060.9 currency units, rounded for display.
How to interpret your result
First payment is number one and receives no escalation. The entered rate is an assumption.
Return measures must cover the same time period before comparison. CAGR annualises two endpoint values but does not model interim cash flows. Current income yield differs from total return or yield to maturity.
Frequently asked questions
Can CAGR handle money added during the period?
The simple endpoint CAGR model does not account for intermediate deposits and withdrawals. Those require cash-flow-aware methods.
