Formula
Sales Tax Calculation Formulas:
1. Add Tax to Price:
Tax Amount = Price × Tax Rate ÷ 100
Total Price = Price + Tax Amount
2. Extract Tax from Price:
If price includes tax:
Price Before Tax = Price ÷ (1 + Tax Rate ÷ 100)
Tax Amount = Price - Price Before Tax
If price doesn't include tax:
Price Before Tax = Price
Tax Amount = Price × Tax Rate ÷ 100
3. Multiple Items Tax:
For each item:
Item Total = Price × Quantity
Item Tax = Item Total × Tax Rate ÷ 100
Item Total With Tax = Item Total + Item Tax
Subtotal = Sum of all Item Totals
Total Tax = Sum of all Item Taxes
Total With Tax = Subtotal + Total Tax
4. Tax Exempt Threshold:
