Frequently asked

How do I calculate percentage change?

Subtract the old value from the new one, divide by the old value, then multiply by 100. The second calculator does it for you.

How do I work out a discount?

Use the discount calculator: enter the original price and the percentage off to see what you pay and what you save.
