Assumptions
- Inflation is treated as a constant annual rate.
- Actual prices can vary by category and location.
Formula Used
Future cost = current cost x (1 + inflation rate)^years
Inflation compounds over time, so future costs can rise faster than a straight-line estimate.
Example inflation
- Start with a cost of 10,000.
- Assume 6% annual inflation.
- Estimate the future cost after 10 years.
Common Mistakes and Limitations
Common mistakes
- Treating an estimate as a guaranteed outcome.
- Ignoring fees, taxes, penalties, or changing rates.
- Using annual and monthly rates interchangeably.
- Forgetting that a calculator is only as reliable as the inputs entered.
Limitations
- The rule may be too simple for complex financial situations.
- It does not replace personalized advice from a qualified professional.
- Real results can change because of taxes, fees, rates, inflation, and behavior.
