An inflation adjustment calculator converts historical monetary values to current dollars (or vice versa) using CPI data. A salary of $10,000 in 1970 is equivalent to roughly $80,000 today after adjusting for inflation. Inflation adjustment is essential for comparing prices, wages, and investments across different time periods.
