Frequently Asked Questions
What is Reverse Sales Tax (Tax-Inclusive)? ↓
Reverse tax calculation determines the pre-tax price when you already know the total price including tax. The pre-tax price is calculated as Total ÷ (1 + Tax Rate).
Is tax calculated before or after the discount? ↓
In most jurisdictions and retail environments, sales tax is legally calculated on the final discounted sale price rather than the original manufacturer suggested retail price (MSRP).
Can I calculate VAT or GST? ↓
Yes, VAT (Value Added Tax) and GST (Goods and Services Tax) use identical percentage arithmetic. Simply enter your regional rate (e.g., 20% for UK VAT or 10% for Australian GST).
Does this calculator store or transmit my financial numbers? ↓
No. All calculations run strictly in your web browser. No figures are logged or sent to any server.
