Add Tax
Total = Price × (1 + Rate / 100)£100 × 1.20 = £120 (at 20% VAT)
Tax Amount
Tax = Price × (Rate / 100)£100 × 0.20 = £20 tax
Remove Tax
Pre-tax = Total ÷ (1 + Rate / 100)£120 ÷ 1.20 = £100 (reverse 20%)
VAT, GST & Sales Tax
US Sales Tax
The US has no federal sales tax. Rates vary by state (0–10%+) and can include county/city add-ons. Over 10,000 unique tax jurisdictions exist across the country.
European VAT
EU VAT (Value Added Tax) is applied at each stage of production. Standard rates range from 17% (Luxembourg) to 27% (Hungary). Most countries have reduced rates for essentials.
GST (Global)
Many countries use GST (Goods & Services Tax) — functionally similar to VAT. India's GST has 4 slabs (0, 5, 12, 18, 28%). Australia's is a flat 10%.
Reverse Tax Formula
To remove tax from a gross amount: Pre-tax = Total ÷ (1 + rate). For example, to extract 20% VAT from £120: £120 ÷ 1.20 = £100 pre-tax, £20 tax.
