How do I calculate a 20% discount?

To calculate 20% off, multiply the original price by 0.20. Subtract that number from the original price. Example: $50 × 0.20 = $10 discount. $50 - $10 = $40 final price.

Is tax calculated before or after discount?

In most jurisdictions (like the US and Canada), sales tax is calculated on the *discounted* price, not the original sticker price. This saves you money on taxes as well.

How do I interpret 'Double Discounts'?

Stores often say 'take an extra 20% off'. This usually means you take the first discount (e.g., 50% off), get a new subtotal, and then take 20% off that *new* number. It is rarely a simple addition (50% + 20% ≠ 70% off).

Never Miss a Deal Again

Whether it's Black Friday, Cyber Monday, or just a clearance rack at your local store, understanding the final price is key to smart shopping. Our Discount Calculator removes the mental math, letting you instantly see the final price—including sales tax—so you know exactly what you'll pay at the register.

What is a Discount Calculator?

A discount calculator is a tool used to determine the reduced price of a product or service. It takes the Original Price and subtracts the Discount Percentage (or fixed amount off) to verify the real cost.

It's essential because sales tax often confuses the final number. A "$50 item at 20% off" isn't exactly $40 out of your pocket if your state has an 8% sales tax. Our tool handles that second step for you.

How to Calculate a Discount Manually

If you don't have this tool handy, here is the simple formula:

Final Price = Original Price - (Original Price × Discount Rate)

For example, for a $100 shirt at 25% off:
$100 - ($100 × 0.25) = $75.

If you work retail, you might get a 15% or 20% employee discount. Calculate exactly how much of your paycheck will go toward that new purchase.

Business Pricing

Can I calculate tax with this?

Yes. Simply look for the "Sales Tax" field in our calculator. Enter your local tax rate (e.g., 8.25%) to see the final, post-tax price.

What is a BOGO deal?

BOGO stands for "Buy One, Get One". A "Buy One Get One Free" deal is effectively a **50% discount** if you buy two items of equal value.
