To quickly calculate a discount of 10 percent off an original price in your head, just move the decimal point one place to the left. If you need 20% off, just double that number. For example, 10% of $50 is $5, so 20% is $10. Your final sale price is $40.

This is called a double discount. You do not simply add them to get 30%. First, apply the 20% discount to the original price to get the subtotal. Then, apply the 10% discount to that new subtotal. Using a double discount calculator approach always yields slightly less total savings than adding the percentages directly.
