How It Works
The Discount Calculator uses the following formulas:
Discount Amount = Original Price × (Discount Percentage / 100) Price After Discount = Original Price - Discount Amount Tax Amount = Price After Discount × (Sales Tax Percentage / 100) Final Price = Price After Discount + Tax Amount For reverse calculation: Original Price = Final Price / ((1 - Discount Percentage / 100) × (1 + Sales Tax Percentage / 100))
This calculator allows you to calculate discounts and final prices, including sales tax. You can also perform reverse calculations to find the original price given a final price and discount percentage.
How to Use
- Choose between "Calculate Discount" or "Reverse Calculate" mode.
- Enter the price (original price for discount calculation, or final price for reverse calculation) in the first input field.
- Input the discount percentage.
- If applicable, enter the sales tax percentage (default is 0%).
- The calculator will automatically update the results, showing the original price, discount amount, price after discount, tax amount, and final price.
- Adjust any input using either the text fields or the sliders to see how it affects the results.
