What is Discount Calculator?

A discount calculator instantly shows the final sale price and how much you save when a discount percentage is applied. Compare multiple discount tiers or stack discounts to find the best deal before you buy.

Type any original price and a percent-off and the breakdown updates as you type: amount saved, sale price, optional sales tax on the discounted total, and the final amount you pay. Quick-discount buttons jump to 10, 15, 20, 25, 30, and 50 percent so common holiday flyers take one click to verify. A Second Discount field models stacked promotions like 'extra 10% off clearance' and shows the effective combined rate. Two reverse modes let you start from the sale tag: Find Original Price solves for the pre-sale price when you know the discount, and Find Discount % computes the percent off when you only have the original and sale price. A discount-type toggle switches the percent field to a flat Amount Off box for fixed-value coupons. Bundle Deal mode prices buy-two-get-one and 3-for-2 style offers, showing the effective price each and total saved. Multiple Items mode adds up to five sale items with their own discounts into one grand total with combined savings. A 'Price already includes tax' toggle backs the tax out before discounting for VAT-inclusive shelf prices, and a currency dropdown switches the symbol across thirteen common options.

How to use

  1. Enter the original price of the item.
  2. Enter the discount percentage (e.g., 25%) to see the sale price and dollar amount saved.
  3. Optionally add a sales tax rate to see the final after-tax price.

When to use

  • Sanity-checking the marked-down tag against the listed percent off at the register.
  • Pricing a 'buy one, get one' or 3-for-2 shelf offer in Bundle Deal mode to see the real per-item cost.
  • Estimating your final total at checkout when sales tax shows separately on the receipt.

Result

A $89.99 jacket at 30% off: you save $27.00, sale price is $62.99. Add 8.5% sales tax on the discounted total and the register rings $68.35.

FAQ

Is a 20% off coupon the same as paying 80% of the original price?
Yes. 20% off means you subtract 20% of the original, leaving 80%. So a $50 item becomes $40. The savings line shows $10 and the sale price shows $40. Both views of the same math agree.
How do I stack two discounts, like 30% off and an extra 10% off?
Stacked discounts multiply, they don't add. Switch on the Second Discount field and the tool does the math for you: a $100 item at 30% becomes $70, and a further 10% off that lands at $63, so total savings are $37, not $40. The breakdown also shows the effective single-rate discount (37%) so you can compare it against a one-shot coupon.
Should I add tax before or after the discount?
Tax is calculated on the discounted price. Enter the discount first so the sale price drops, then enter the tax rate and the tool charges tax only on what you actually pay. This matches how cash registers and online checkouts handle it in most regions.
What if the price already includes tax?
Two ways. If the shelf price already includes tax, switch on 'Price already includes tax' in Standard mode and enter your tax rate: the tool strips the tax, applies the discount to the pre-tax amount, then adds tax back so the final figure matches the register. If you would rather treat the marked price as the all-in total, just leave the tax field empty and you'll see the discount and sale price with no separate tax line, which is the typical VAT-inclusive case in Europe.
Why does the savings line jump when I move between 25% and 30%?
Each percent off translates to 1% of the original price in savings. On a $200 jacket that's $2 per percent, so jumping 5 points adds $10 to your savings. Small percentage moves matter more on big-ticket items than on cheap ones.
