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.
