Tax = subtotal × tax rate. Total = subtotal + tax.
Subtotal $100, tax rate 8.25%: tax = $100 × 0.0825 = $8.25, and total = $100 + $8.25 = $108.25.
Rates, taxable items, sourcing rules, and local surtaxes vary by jurisdiction. Some items may be exempt or taxed at a different rate, and the applicable rate must be confirmed for the actual transaction — this calculator applies one rate to the whole subtotal.
Tax = subtotal × tax rate; total = subtotal + tax. One rate is applied to the whole subtotal you enter.
