How It Works
The sales tax rate percentage is converted to a decimal by dividing by 100. That decimal is then multiplied by the pre-tax price to calculate the exact tax amount: Tax = Price × (Rate ÷ 100). The total final price is the pre-tax price plus the tax amount: Total = Price + Tax. For example, a $100 item at 7.25% sales tax produces a $7.25 tax charge and a $107.25 total. All three values — original price, tax amount, and final total — are displayed so you can see exactly how the final price is composed. Sales tax rates vary widely: US state rates range from 0% (in states like Oregon and Delaware) to over 10% when state and local rates are combined. Always use the combined rate for your specific city or county for an accurate total.
