How to Use the Discount Calculator
Calculate the sale price and total savings on any discounted item in seconds:
- Enter the original price — type the full retail price of the item before any discount.
- Choose discount type — toggle between Percentage (%) mode (e.g. 20% off) or Fixed Amount ($) mode (e.g. $15 off).
- Enter the discount value — type the percentage or dollar amount of the discount.
- Add tax (optional) — enter your local sales tax rate to see the final price including tax.
Results update instantly as you type. The calculator shows the discount amount, the final sale price, your total savings, and the after-tax price if a tax rate is provided.
Frequently Asked Questions
How do I calculate a discount percentage?
Multiply the original price by the discount percentage divided by 100. For example, 25% off a $80 item: $80 × 0.25 = $20 discount, so the sale price is $60.
How do I find the sale price after a fixed dollar discount?
Simply subtract the discount amount from the original price. For example, $10 off a $45 item gives you a final price of $35.
Can I include sales tax in the calculation?
Yes. Enter your local tax rate in the optional Tax Rate field and the calculator will display the final price with tax applied after the discount.
What is the difference between discount percentage and discount amount?
A discount percentage removes a proportion of the price (e.g. 20% off), while a discount amount removes a fixed dollar value (e.g. $15 off). Use the toggle to switch between the two modes.
Is this calculator accurate for all currencies?
The math works for any currency. The dollar sign shown is just a placeholder — the discount formula (original price minus discount) is universal regardless of currency.
