The Percent Off Formula
Calculating a percentage discount requires two fundamental arithmetic operations: multiplication to determine the dollar savings, followed by subtraction to determine the final sale price.
Visual Calculation Flowchart Diagram
Input Variable A Original Price e.g., $100.00
Operation 1 (×) Discount Rate (% ÷ 100) = 0.25
Step 1 Result Discount Amount Save $25.00
Step 2 Result (−) Final Sale Price Pay $75.00
Step 1: Calculate Savings
Multiplication Discount Amount = Original Price × (Discount % ÷ 100)
Multiply the listed retail price by the decimal equivalent of the discount percentage to find the exact dollar amount subtracted from your bill.
Step 2: Calculate Sale Price
Subtraction Final Sale Price = Original Price − Discount Amount
Subtract the calculated discount amount from the original price to determine the exact checkout total due before applicable local sales tax.
Direct Single Step Shortcut
Final Price = Original Price × (1 − Discount Rate)
For example, on a 30% markdown: 1 − 0.30 = 0.70. Multiply the starting price directly by 0.70 to get the payable amount in one single step without separate subtraction.
Spreadsheet Syntax (Excel / Google Sheets)
=A1 * (1 - B1)
Where A1 contains the original price ($120.00) and B1 contains the discount rate formatted as a percentage (25% or 0.25).
