Understanding Your Results
What This Number Means
Your personal inflation rate represents the weighted average of price increases across all the categories where you spend money. It reflects your actual cost-of-living increase — not a theoretical national average.
A rate higher than the official CPI means your spending patterns expose you to more inflationary pressure than the average American. This is common for renters, families with young children, and those with significant healthcare costs.
What You Can Do
- Budget Planning: Use your personal rate, not CPI, for realistic financial projections.
- Salary Negotiation: Document your actual cost increases when requesting raises.
- Retirement Planning: Ensure your savings growth exceeds your personal inflation rate.
- Investment Strategy: Consider whether your portfolio returns beat your personal inflation.
