Master the Math of Retail Discounts
Whether you are shopping during Black Friday, evaluating a BOGO (Buy One Get One) deal, or calculating the exact cost of an item after local sales tax is applied, running the math mentally can be prone to errors. The Calculay Discount Calculator instantly computes your exact out-of-pocket final price.
How to Calculate a Discount
Calculating a simple percentage discount requires a two-step mathematical formula:
- Step 1 (Find the Savings Amount): Multiply the Original Price by the Discount Percentage (in decimal form). For a $50 item at 20% off: $50 x 0.20 = $10 Savings.
- Step 2 (Find the New Price): Subtract the Savings Amount from the Original Price. $50 - $10 = $40 Final Price.
The Sales Tax Trap
A common mistake shoppers make when budgeting is ignoring local sales tax. An item advertised as "30% off" might seem like an incredible deal, but if your local jurisdiction mandates a 9% sales tax, your "true" discount drops significantly.
