The Silent Tax of Inflation
Inflation is the invisible erosion of your purchasing power over time. If a gallon of milk costs 3% more this year, but your salary remained flat, you essentially took a 3% pay cut. Calculating salary inflation allows you to negotiate fairly during performance reviews by demanding adjustments simply to \"break even\" with the cost of living.
Inflationary Mechanics
CPI (Consumer Price Index)
The government metric used to track the average change in prices paid by urban consumers for a market basket of consumer goods and services.
Cost of Living Adjustment (COLA)
A standard wage increase designed to exactly match the rate of inflation. A true promotion or raise requires a percentage increase ABOVE the current COLA rate.
Compounding Inflation
Just like investments, inflation compounds. A 3% inflation rate for 10 straight years does not equal 30% total inflation; due to compounding, prices are actually ~34% higher.
