Which CPI data does this calculator use?

What is the difference between CPI and inflation?

CPI is the measurement tool that tracks price levels, while inflation is the rate of change in that index over time.

How does inflation affect different people differently?

Inflation impacts everyone based on their financial situation. Savers lose purchasing power while borrowers with fixed-rate debt may benefit.

What is purchasing power and how is it calculated?

Purchasing power represents what your money can actually buy. It's calculated by comparing the CPI of a base year to the current CPI.

How accurate is US CPI data for personal inflation?

US CPI data is highly accurate for national average inflation but may not reflect your personal experience due to spending patterns and regional variations.

Should I use average inflation rate in my planning?

The 3.5% average inflation rate is a reasonable conservative estimate for long-term planning, but you should adjust based on your specific situation.

How does inflation affect investment returns?

Inflation significantly impacts investment returns through real vs. nominal returns. Always consider after-inflation (real) returns when comparing investment options.
