How Does Discount Calculator Work?
Savings are calculated by multiplying the original price by the discount rate divided by 100. The final price is the original price minus savings plus any sales tax.
Savings = Original Price × (Discount % / 100) | Final Price = (Original Price − Savings) × (1 + Tax % / 100)Practical Examples
Single 25% Clearance Sale
Original Price: $120.00, Discount: 25%, Sales Tax: 8%.
Frequently Asked Questions
How do stacked/double discounts work?
Stacked discounts are applied sequentially, not added together. A 20% discount followed by an extra 10% discount on a $100 item reduces it to $80 first, then takes 10% off $80 ($8), giving a final price of $72 (a total 28% discount, not 30%).
How do I calculate 20% off manually?
To calculate 20% off quickly in your head, find 10% by moving the decimal point one place to the left, double that amount, and subtract it from the original price.
Does this calculator handle currency conversions?
The discount calculator works with any currency (USD, EUR, GBP, INR, CAD) as the mathematical ratios remain identical.
Can I calculate fixed dollar discounts?
Yes! Toggle to "Fixed Amount" mode to subtract a specific dollar amount rather than a percentage.
Is tax calculated before or after the discount?
In almost all legal jurisdictions, sales tax is assessed on the final discounted sale price, not the original sticker price.
