Discount Calculator

Whether you are shopping online, comparing sale prices, or checking if a discount adds up correctly, our Discount Calculator on Diztool gives you the answer in seconds. It works in three modes so you can solve any discount problem. Mode 1 — Find the Sale Price: 1. Enter the original price. 2. Enter the discount percentage. 3. Instantly see the discounted amount saved and the final sale price. Mode 2 — Find the Discount Percentage: 1. Enter the original price. 2. Enter the sale price you are seeing. 3. The tool calculates what percentage off was applied. Use this to verify advertised discounts. Mode 3 — Find the Original Price: 1. Enter the sale price shown. 2. Enter the discount percentage that was applied. 3. The tool works backwards to show the original price before the discount. Discount Formulas: Sale price = Original price x (1 - discount / 100) Discount amount = Original price x (discount / 100) Discount % = (Original price - Sale price) / Original price x 100 Original price = Sale price / (1 - discount / 100) Common Shopping Scenarios: Black Friday deals — A 200 dollar jacket at 30 percent off: savings = 60 dollars, sale price = 140 dollars. Stackable discounts — A 10 percent member discount plus a 15 percent sale are not the same as 25 percent off. They are applied sequentially. On a 100 dollar item: 10 percent off gives 90 dollars, then 15 percent off 90 gives 76.50 dollars — a combined 23.5 percent discount, not 25 percent. Verifying sale prices — Retailers sometimes advertise misleading discounts. Enter the "was" and "now" prices to instantly verify the actual percentage off. Bulk purchase pricing — Calculate whether a bulk price represents the claimed discount percentage. Tax after discount — Discount is typically applied before tax. To find the final price with tax, calculate the discounted price first, then apply your sales tax rate on top.
