FAQs
How do I calculate price before tax?
To remove tax: Price / (1 + (TaxRate/100)). For example, $120 / 1.20 = $100.
What is the difference between sales tax and VAT?
Sales tax is applied only at the final point of sale to consumers. VAT (Value Added Tax) is applied at each stage of production and distribution, but the end consumer ultimately pays it.
How do I add tax to a price?
Multiply the price by (1 + TaxRate/100). For example, $100 × 1.08 = $108 with 8% tax included.
What is GST?
GST (Goods and Services Tax) is similar to VAT. It's a consumption tax applied to goods and services. Countries like Australia, Canada, and India use GST systems.
What are common sales tax rates?
US sales tax ranges from 0% (no sales tax states like Oregon) to 10%+ (combined state and local). UK VAT is 20%. EU VAT ranges from 17-27%. Canada GST/HST is 5-15%. Check your local jurisdiction for exact rates.
Can I use this for business expense calculations?
Yes! Use "Remove Tax" mode to extract the net price from receipts and invoices. This is essential for accounting, tax returns, and expense reports where you need to separate the product cost from the tax paid.
