How to Calculate a Discount?

Whether you are shopping for groceries, electronics, or clothes, figuring out the exact sale price can be tricky if you are doing the math in your head. Our completely free Percent Off Calculator does the heavy lifting for you.

  1. Original Price: Enter the sticker price of the item before any sales or coupons are applied.
  2. Discount (%): Enter the percentage off (e.g., enter 20 for a 20% off sale).
  3. Sales Tax (Optional): If you want to know exactly what you will pay at the register, enter your local sales tax percentage.
  4. Calculate: Instantly see your final price, exactly how much money you are keeping in your pocket, and the tax added.

The Discount Formula

If you want to do the math manually, the formula to find the savings amount is simple:

Savings = Original Price × (Discount Percentage ÷ 100)

You then subtract the Savings from the Original Price to get your Final Price.

Frequently Asked Questions (FAQ)

Is sales tax calculated before or after the discount?

In almost all retail scenarios, sales tax is applied after the discount is taken off the original price. Our calculator follows this standard retail rule: it calculates the discounted price first, and then applies the sales tax to that lower amount.

How do I calculate a 20% discount on $50?

To calculate a 20% discount, you multiply the original price ($50) by 0.20 (which is 20%). That gives you $10 in savings. Subtract the $10 savings from the original $50, and your final price is $40.

Can I use this for business or wholesale pricing?

Yes, this tool is perfect for both everyday retail shopping and business-to-business (B2B) transactions to calculate trade discounts, bulk pricing deals, and final invoice amounts.
