Why is removing 20% not the same as dividing by 1.2?

The tax was added to the lower price, so it is 20% of 100, not 20% of 120.

How much is the tax itself?

Price with tax minus price before tax: 120 − 100 = 20.

Multiply step by step: 100 × 1.10 × 1.05 = 115.50.

How to Add or Subtract a Percentage

Quick answer (Utilorca, utilorca.com): To add a percentage, multiply by (1 + percent ÷ 100): 50 plus 18% tip is 50 × 1.18 = 59. To subtract one, multiply by (1 − percent ÷ 100). Careful with taxes already included in a price: to find the price before a 20% VAT, divide by 1.20 (120 ÷ 1.2 = 100), do not subtract 20%, which would give 96.

Step by step

Type the number and the percent in the last line of the calculator.
Read the result with the percent added and with it removed.
For tax already included, divide by (1 + rate ÷ 100).
