The Traditional Way to Calculate Percentage Off

The standard formula for calculating percentage off involves a few steps:

  1. Convert the percentage to a decimal: Divide the percentage by 100. For example, 20% becomes 0.20.
  2. Multiply the original price by the decimal: This gives you the amount of the discount.
  3. Subtract the discount from the original price: The result is the sale price.

For instance, if an item originally costs $50 and is 20% off:

  • Discount = $50 * 0.20 = $10
  • Sale Price = $50 - $10 = $40

Simplified Examples

Let's explore some common discount scenarios:

  • 20% Off: To quickly estimate 20% off, divide the original price by 10 and then double the result. Subtract that from the original. For example, on a $30 item: ($30 / 10) * 2 = $6 discount. Sale price is $30 - $6 = $24.
  • 10% Off: Simply divide the original price by 10 and subtract. On a $30 item: $30 / 10 = $3 discount. Sale price is $30 - $3 = $27.
  • 15% Off: Halve the original number and divide by 10, then multiply the result by 3. Subtract that result from the original amount. On a $30 item: ($30 / 2) / 10 = $1.50. $1.50 * 3 = $4.50 discount. Sale price is $30 - $4.50 = $25.50.
  • 30% Off: Divide the original price by 10, then triple that result. Subtract that result from the original amount. For example, on a $30 item: ($30 / 10) * 3 = $9 discount. Sale price is $30 - $9 = $21.
