Formula
The discount is calculated first. Optional tax is then applied to the discounted price.
Discount = price × discount% ÷ 100
Final price = (price − discount) × (1 + tax% ÷ 100)
Final price = (price − discount) × (1 + tax% ÷ 100)
How it works
1
Enter the original price.
2
Enter the discount percentage.
3
Optionally add tax that applies after the discount, then review the savings and final price.
Important notes
Tax rules and whether tax is applied before or after a discount vary by jurisdiction and transaction. This tool follows the order stated above.
