Master one of the most misunderstood concepts in finance, news, and data analysis: knowing when a change is absolute versus relative.

Classic Example Interest rate rises from 3% to 4%

0% 3% (Before) 4% (After) 10%

Absolute Difference +1 percentage point

Simple subtraction of the two percentages:

4% − 3% = 1 percentage point

Relative Change +33.3% increase

The change divided by the starting value:

(4% − 3%) ÷ 3% = 1/3 ≈ 33.3%
