Old rate: 4% · New rate: 5%

  1. 01

    Point difference: 5 − 4 = 1 percentage point.

  2. 02

    Basis points: 1 × 100 = 100 bps.

  3. 03

    Relative increase: (5 − 4) ÷ 4 × 100 = 25%.

Up 1 percentage point, equivalent to 25% relative growth.

Illustrative example · A change of one point can be a large relative change when the original rate is small.

Formula & method

Percentage-point change = new percentage − old percentage

If a rate rises from 20% to 25%, the change is 5 percentage points but a 25% relative increase. PercentScope shows both values side by side.
