The formulas for percentage calculations

• Percentage value: V = B × p ÷ 100
• Percentage rate: p = W ÷ G × 100
• Base value: G = W × 100 ÷ p
• Percentage change: (new value − old value) ÷ old value × 100

Everyday examples

• 19% VAT on €250 is €47.50.
• A 30% discount on €80 results in a price of €56.
• If a price rises from €2.49 to €2.79, that is an increase of 12.05 per cent.

Frequently asked questions

What is the difference between per cent and percentage points?

If an interest rate rises from 2 per cent to 3 per cent, that is an increase of one percentage point – but a rise of 50 per cent.

How do I work out a discount?

Multiply the price by (1 − discount ÷ 100). For a 25 per cent discount on €60, that’s 60 × 0.75 = €45.
