Discount Calculator

Discount calculator to find the sale price, savings, and totals

A discount calculator helps you answer one question fast: “What will I actually pay after the discount?” Stores and online checkouts can display discounts in different ways. Sometimes it is a percentage like 15% off. Sometimes it is a fixed amount like 250 off. And sometimes the price you care about is the final total after tax, VAT, or buying multiple items. This calculator puts those pieces in one place so you can make a clean decision before you buy.

Start by entering the original price. Then choose whether your discount is a percent discount or a fixed amount discount. If you have a percent discount, enter the percent number (for example, enter 15 for 15%). If you have a fixed amount discount, enter the amount you are taking off the price (for example, 250). The calculator will show your savings and the discounted price. If you also want a more complete “checkout-like” number, add an optional tax or VAT percent and an optional quantity. You will then see the tax amount and the total for the quantity you entered.

This is useful in normal shopping situations: comparing two deals that are shown differently, checking whether a voucher is better than a percentage sale, and estimating the real cost when VAT applies. It is also useful for small business pricing checks when you want to see the impact of a discount on the amount you charge, especially if you sell in multiples or bundles.

Assumptions and how to use this calculator

• The “Original price” is the price before discount and before tax or VAT.
• Percent discounts are applied to the original price. Fixed discounts are subtracted from the original price.
• If you enter tax or VAT percent, it is applied after the discount (discounted price × tax rate).
• If you enter quantity, totals are calculated as per-item amounts multiplied by quantity.
• Results are rounded to two decimals for display. Your card statement may differ slightly due to retailer rounding rules.

Common questions

Should I use percent discount or fixed discount?

Use whatever matches the offer you are seeing. A percent discount (like 20% off) scales with price, so it removes more money on higher-priced items. A fixed discount (like 100 off) removes the same amount regardless of price. If you are comparing two offers, calculate both options and compare the final price and savings side by side.

What if my fixed discount is bigger than the price?

In real checkouts, prices do not go below zero. This calculator will treat the discounted price as zero if the fixed discount is equal to or greater than the original price. If you see a negative number at a store checkout, it usually means the discount is being applied across multiple items or the system is handling it as store credit rather than a single-item reduction.

Does tax or VAT apply before or after a discount?

It depends on local rules and how the retailer structures the transaction, but most consumer pricing applies tax to the discounted price. That is what this calculator assumes. If your situation is different, you can still use the tool by entering tax as zero and treating the “Discounted price” as your base to compare against a separate tax calculation.

How do I compare two deals like “15% off” vs “Save 200”?

Run the same original price through both discount types. For the percent deal, enter the percent. For the fixed deal, select fixed amount and enter the amount. Compare the savings and the final price. The better deal is the one with the lower final price. If you care about cash saved rather than final price, compare savings instead.

Can I use this for multiple items or a basket?

Yes, but it is simplest when items have the same price and the same discount. Enter the per-item original price and set quantity to the number of items. If your basket has different prices or different discounts, calculate each item separately or use an average price only if the discount is uniform across the basket.
