Discount Calculator — Percent Off & Sale Price Calculator

Introduction

Sale math shouldn't slow you down. Trencada's Discount Calculator is a free online tool that instantly works out sale prices: enter the original price and the discount percentage, and see the discount amount, the final price, and your total savings—no manual arithmetic, no signup. Every calculation runs locally in your browser, so nothing you enter is ever uploaded or stored.

How to Use the Discount Calculator

Step 1: Enter the Original Price

Type the item's price before the discount into the Original Price field. It cannot be negative.

Step 2: Enter the Discount Percentage

Type the "% off" value—for example, 20. It must be between 0 and 100.

Step 3: Choose a Currency Symbol

Pick $ (USD), € (EUR), £ (GBP), or None. The symbol appears across all results.

Step 4: Set the Output Options

Keep "Round to 2 decimal places" and "Show calculation formula" ticked for clean, transparent results. Tick "Include tax calculation" if you also want the price with a 10% tax added.

Step 5: Click "Calculate"

Press the Calculate button to see your results instantly.

Step 6: Review, Copy, or Start Over

See the final price after discount, how much you save (with the percentage), the step-by-step formula, and—if enabled—the tax-inclusive price. Use Copy Result to copy the final price to your clipboard, or Start Over to clear everything and run a new calculation.

FAQs

1. How do I calculate a discount?

Multiply the original price by the discount percentage and divide by 100.

For example, a $200 item with a 25% discount has a discount amount of $50.

2. How do I calculate the final price after a discount?

Subtract the discount amount from the original price.

For example, if the original price is $200 and the discount is $50, the final price is $150.

3. How much is 20% off $100?

A 20% discount on $100 is $20, so the final price is $80.

4. Can I calculate any discount percentage?

Yes. You can enter any discount percentage and the calculator will determine the discount amount and final price.

5. Can I use the calculator for multiple items?
