Discount Calculator
This calculator computes the sale price and total savings when a percentage discount is applied to an original price. Enter the original price and the discount percentage to see how much you save and what you pay.
How It Works
Multiply the original price by the discount rate (expressed as a decimal) to find the dollar savings. Subtract savings from the original price to get the sale price. You can also calculate sale price directly as original price × (1 − discount/100).
Worked Examples
Example 1. $120 item at 25% off. Savings = $120 × 0.25 = $30. Sale price = $90.
Example 2. $49.99 item at 15% off. Savings ≈ $7.50. Sale price ≈ $42.49.
When to Use This Calculator
Use at checkout to verify a sale price, compare deals across stores, or evaluate whether a "sale" represents genuine savings.
Frequently Asked Questions
Does this include sales tax?
No. Use the Sales Tax Calculator after applying the discount to find the final price with tax.
How do I stack two discounts?
Apply the first discount, then apply the second discount to the already-reduced price. They do not add — a 20% + 10% discount is not 30%.
What if the discount is in dollars, not percent?
Simply subtract the dollar discount from the original price. No conversion needed.
