How It Works
Discount amount = original price × discount percentage. Sale price = original price − discount amount. If you add an extra tax or fee percentage, the calculator applies it after the discount to estimate the final total.
Example
A $100 item with 20% off saves $20, so the sale price is $80 before tax or extra fees. If an extra 10% fee is added after the discount, the final estimate becomes $88.
Best use cases
- Check sale price before checkout.
- Estimate how much money a discount saves.
- Compare two discount percentages on the same item.
- Add a rough tax or service fee estimate after discount.
Shopping assumptions to verify
- Coupons may exclude some products or brands.
- Taxes, shipping, and platform fees can reduce the real savings.
- Some stores round prices differently at checkout.
- Currency display changes formatting only and does not perform FX conversion.
Frequently Asked Questions
Can I include tax?
Yes. Use the optional tax or fee field to estimate a final total after the discount.
Can I change currency?
Yes. Choose a display currency such as USD, EUR, GBP, JPY, SGD, INR, or VND. This only formats the entered prices; it does not convert exchange rates.
Is the tax applied before or after the discount?
This draft applies the extra tax or fee after the discount. Some stores or countries may use different rules, so verify important purchases.
Can this compare two sales?
Yes. Run each sale separately and compare final price and savings. For price-per-unit comparisons, use the unit price calculator.
