💡 Comprehensive Guide to Discount & Tax Calculator
1. How do I calculate a simple discount?
Enter your Original Price, then enter either the Discount Rate (%) or the specific Discount Amount ($). The calculator will automatically sync the two fields and immediately show your final discounted price below.
2. How does the Sales Tax feature work?
By toggling "Include Sales Tax (10%)", the calculator will compute a 10% tax on the after-discount amount and add it to your final total. This is crucial for accurate invoicing or shopping in regions with value-added taxes (VAT).
3. What is the "Input price is pre-tax" toggle used for?
If you have a price that already includes tax, but you need to know the base price and the tax amount separately (reverse calculation), turn this toggle off. The calculator extracts both the pre-tax price and the pre-tax portion of the discount, so a 10% discount on a tax-inclusive $11,000 total correctly produces a $9,900 final total.
