375

15% of 2,500 = 375

Formula

X% of Y = X ÷ 100 × Y

X as % of Y = X ÷ Y × 100

% change = (New − Old) ÷ |Old| × 100

Y + X% = Y × (1 + X ÷ 100)

'Percent' means 'per hundred', so every percentage calculation is a division or multiplication by 100.

Examples

  • 15% of 2,500

    15% of 2,500 = 375

  • 45 out of 60 as a percentage

    45 is 75% of 60

  • Price rises from 80 to 100

    80 → 100 is a 25% increase

  • Add 18% GST to 10,000

    10,000 + 18% = 11,800

Important information

  • A percentage increase followed by the same percentage decrease does not return you to the start: 100 + 10% = 110, then 110 − 10% = 99.
  • Percentage points are different from percent: a rate moving from 10% to 12% is a 2 percentage-point rise, but a 20% increase.
