Percent Off Calculator

What is the Percent Off Calculator?

Find what percentage discount you are getting from the original and sale price. Turning an original and sale price into a percentage shows the real size of a discount, which is often different from the sign.

How to use the Percent Off Calculator

1. Enter your original price, your sale price.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: percent off, amount saved.
4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

Worked example

With original price = $120, sale price = $84, the Percent Off Calculator returns percent off: 30.00%; amount saved: $36.00.

Where the Percent Off Calculator helps in real life

A TV dropped from $799 to $559. The calculator shows a 30% discount, so you can compare it with a competitor’s “25% off” offer.

An outlet store shows only sale prices with a crossed-out list price. Calculating the percentage helps you judge whether the deal is as good as it looks.

Common mistakes to avoid

• Comparing dollar savings across items with very different prices.
• Trusting an inflated “was” price.
• Forgetting tax and shipping in the final comparison.
• Calculating from the sale price instead of the original.

💡 Practical tip: A large percentage off is only a good deal if the original price was realistic.

Tips for better results

• Compare the final prices, not only the percentages.
• Check the item’s price history before buying.
• Use the unit price calculator for bulk items.
