Features
Handles both directions: forward (price × (1+rate)) and reverse (total ÷ (1+rate)), so it works whether you’re a shopper or a seller reconciling receipts.
Benefits & Use Cases
Shoppers predict checkout totals, sellers quote tax-inclusive prices, and travelers compare costs across states with different rates.
Tips
US sales tax varies by state and even city — look up your combined local rate rather than guessing the state figure alone.
Frequently Asked Questions
How is sales tax calculated?
Net price × tax rate gives the tax; add it for the total.
How do I remove tax from a total?
Divide the total by (1 + rate): a $108 total at 8% tax = $100 net.
Is sales tax the same as VAT?
Similar idea, different mechanics — sales tax applies once at retail; VAT applies at each production stage.
What rate should I use?
Your combined state + county + city rate; many US cities stack all three.
