Discount Calculator – Sale Price & Savings Calculator

Use the "Sale Price" mode. Enter the original price and the discount percentage, then click Calculate. The formula is: Sale Price = Original Price × (1 − Discount% / 100). For example, 20% off $120 = $120 × 0.8 = $96. The calculator also shows the amount saved and the savings percentage.

Use the "Original Price" mode. Enter the sale price and the discount percentage that was applied. The formula is: Original Price = Sale Price ÷ (1 − Discount% / 100). For example, if an item costs $80 after a 20% discount, the original price was $80 ÷ 0.8 = $100.

A double (or stacked) discount means applying two consecutive discounts. For example, 20% off then an additional 10% off. This is NOT the same as 30% off. The calculation is: First apply 20% to get $80 (from $100), then apply 10% to $80 to get $72. The effective total discount is 28%, not 30%. Use the "Double Discount" mode to calculate this accurately.

Use the "What % Off" mode. Enter the original price and the current sale price. The formula is: Discount% = ((Original − Sale) ÷ Original) × 100. For example, if an item was $200 and is now $150: ((200−150) ÷ 200) × 100 = 25% off.

Bulk pricing means getting a lower per-unit price when buying in larger quantities. In the "Bulk Pricing" mode, enter the unit price, the quantity you want to buy, and the bulk discount percentage. The calculator shows total savings, price per unit after discount, and a quantity comparison table so you can see how savings scale with different order sizes.

Yes! In the "Sale Price" mode, you can optionally enter a tax rate. The tax is applied after the discount (on the discounted price), which is the standard practice in most regions. The calculator shows the breakdown: original price, discount amount, discounted price, tax amount, and final price including tax.
