How Sales Tax Works
Sales tax is a percentage added to the pre-tax price of goods and services. To calculate the total, multiply the pre-tax price by (1 + tax rate ÷ 100). For a $50 item at 8% tax: $50 × 1.08 = $54 total. The tax amount alone is $50 × 0.08 = $4.
To remove tax from a tax-inclusive total, divide by (1 + rate ÷ 100). US sales tax rates vary by state and city, typically ranging from 0% to over 10%. Always check your local rate for accurate calculations.
