What the Discount Calculator Does
The Discount Calculator helps you compute the discounted price of one or more items by applying either a percentage discount or a fixed amount off per item. It also supports an optional sales tax rate so you can estimate the final amount due. This is perfect for shoppers comparing deals, sellers planning promotions, or anyone who wants to confirm the math behind a price drop.

How to Use the Discount Calculator
- Enter the original price per item.

- Optionally enter your local sales tax rate (for example, 8.25).
- Click Calculate to see your discounted unit price, subtotal, tax, final total, and total savings.
Formula Breakdown
When you choose a percentage discount, the calculator multiplies the original price by the discount rate to find the discount amount, then subtracts that from the original price. For a fixed amount discount, it subtracts the entered amount from the original price. Discounts are applied per item and capped so they never exceed the original price.
- Percentage discount per item = Original price × (Discount % ÷ 100)
- Fixed discount per item = Entered amount (capped at original price)
- Discounted unit price = Original price ? Discount per item
- Subtotal after discount = Discounted unit price × Quantity
- Tax amount (optional) = Subtotal × (Tax rate ÷ 100)
- Final total = Subtotal + Tax amount
Practical Tips for Better Savings
Compare percent vs fixed discounts
Some offers sound generous but may not deliver the best deal. For higher-priced items, a percentage discount often saves more. For lower-priced items, a fixed amount can be better. Try both approaches in the Discount Calculator to see which promotion yields a lower final total.
Watch your tax rate
Sales tax can add up, especially on large purchases or multiple items. Because tax is typically calculated after discounts, entering your local tax rate gives you a truer picture of your out-the-door cost. If you’re shopping in multiple regions or online, check the applicable tax rate for each scenario.
Consider quantity breaks
Buying more units at the same discount changes your total savings and tax, which can impact your decision to stock up now or wait. Adjust quantity in the calculator to model different scenarios and confirm where the best value lies.
