Frequently Asked Questions

What is the difference between VAT and GST?

VAT (Value Added Tax) and GST (Goods and Services Tax) are essentially the same type of consumption tax applied at different stages of production and distribution. The name varies by country — most European countries use "VAT" while countries like Australia, India, and Singapore use "GST". The calculation method is identical.

How do I add VAT to a price?

Select the "Add VAT" tab, enter your net (before-tax) amount, and choose the appropriate VAT rate. The formula is: Gross = Net × (1 + Rate/100). For example, adding 20% VAT to $100 gives you $120.

Example: $100 net + 20% VAT = $100 × 1.20 = $120 gross

How do I remove VAT from a price?

Select the "Remove VAT" tab and enter the gross (tax-inclusive) amount. The formula is: Net = Gross ÷ (1 + Rate/100). For example, removing 20% VAT from $120 gives you $100 net and $20 VAT.

Example: $120 gross ÷ 1.20 = $100 net (with $20 VAT)

Why does my country's VAT rate seem different?

This calculator uses standard (general) VAT rates. Many countries have reduced rates for specific goods like food, medicine, or books. If you need a reduced rate, enter it manually using the custom rate input field.

Important: Always verify current rates with your local tax authority for official compliance.

Can I calculate VAT for multiple items at once?

Yes. Click "Batch Mode" to expand the batch calculator. Enter one amount per line, and the tool will calculate the net, VAT, and gross for each item, plus a total summary at the bottom.

Are the VAT rates accurate?

The rates reflect standard national VAT/GST rates. Tax rates can change due to government policy. For official rates, always verify with your local tax authority. You can also enter any rate manually using the custom input.

Note: This tool is designed for estimation purposes. For tax filing and official documentation, consult with a qualified tax professional or your local tax authority.
