Detailed Guide
Inflation modeling helps translate nominal values into purchasing-power context over time.

Using conservative and expected scenarios improves long-term financial robustness.
Pair inflation projections with savings and income planning for more realistic targets.
Assumptions and Limits
Assumes constant inflation and ignores volatility across categories.
Common Mistakes to Avoid
