Discount Calculator
Calculate discounted prices, savings, and final cost. Supports percentage and fixed amount discounts with tax.
How do I calculate a percentage discount?
Multiply the original price by the discount percentage and divide by 100 to get the savings. Subtract savings from the original price to get the final price.
What is the difference between percentage and fixed discount?
A percentage discount reduces the price by a percentage (e.g., 20% off), while a fixed discount subtracts a set amount (e.g., $5 off).
What is the difference between stacked and separate discount modes?
Stacked mode applies discounts sequentially — each discount is calculated on the price after the previous one. Separate mode calculates each discount independently based on the original price, then subtracts all savings from it.
How does the reverse calculation work?
Reverse mode lets you find the original price from a target final price. Enter the price you want to pay after discounts, and the calculator works backwards to determine the list price you need to set.
How does tax calculation work?
Enter the tax rate percentage in the Tax Rate field. The calculator applies tax to the discounted price, showing the tax amount and total with tax separately in the results.
Can I change the decimal precision?
Yes. Use the Precision field to set how many decimal places are used in all calculations and results. The default is 2 decimal places.
Is my data sent to a server?
No, all calculations are done entirely in your browser.
Can I calculate multiple discounts at once?
Yes, the calculator supports multiple discount entries. You can add as many discounts as needed and choose whether to apply them in stacked or separate mode.
What is a markdown in retail?
A markdown is a reduction in the original selling price, typically used to clear inventory, promote sales, or match competitor pricing. It's different from a coupon because it's applied directly to the item's price.
How do I calculate the original price from a discounted price?
Use the reverse calculation mode. Enter the final price you want to pay and the discount percentage. The calculator will determine the original list price needed to achieve that final price after the discount.
What is the best way to compare different discount offers?
Calculate the final price for each offer using the same original price. The offer with the lowest final price provides the best value. Consider also any additional benefits like free shipping or loyalty points.
Can I use this calculator for business pricing?
Yes, this calculator is useful for businesses to set promotional prices, calculate profit margins after discounts, and determine the impact of sales on revenue. It helps ensure pricing strategies remain profitable.
How do I calculate a discount on a service?
The process is the same as for products. Enter the service's original price and apply the discount percentage or fixed amount. The calculator will show the discounted service price and your savings.
What happens if I apply a discount greater than 100%?
The calculator will show a negative final price, which means the seller would be paying the buyer. In practice, discounts should not exceed 100% unless it's a special promotion or refund scenario.
How to Use Discount Calculator
Calculate the final price, savings, and tax for any discount in seconds. Everything runs locally in your browser, so your numbers never leave your device.
- Type the list price into the Original Price field.
- Enter your discount and choose % or $ to indicate whether it is a percentage or a fixed amount.
- Fill in the Tax Rate (%) and pick Stacked or Separate if you apply more than one discount.
- Press Forward to compute the final price from the original, or Reverse to work backwards from a target price.

With multiple discounts, Stacked and Separate produce different totals, so match the mode to how the shop actually applies them.
