VAT/GST rates and rules vary by country and product. This is a general calculation — check your local rate and tax rules. Computed in your browser.

Estimate only. This calculator provides estimates based on the values you enter and the formula shown. It is not financial advice and may not reflect every fee, tax, or lender requirement. Check figures with a qualified professional before making financial decisions.

Quick answer

To add VAT, multiply the net price by the rate: at 20%, a $100 net price becomes $120 gross, with $20 of VAT. To remove VAT from a gross price, divide by 1 plus the rate: $120 ÷ 1.20 = $100 net, so the VAT was $20. This calculator does both directions at any rate and shows the net, VAT amount, and gross. VAT/GST rates and rules vary by country, so use your local rate.

Formula & method

Let r be the VAT rate as a decimal (20% = 0.20). To add VAT to a net amount N: VAT = N × r and gross = N × (1 + r). To remove VAT from a gross amount G: net = G ÷ (1 + r) and VAT = G − net. The tool applies whichever direction you choose and rounds the displayed money to two decimals.

Examples

Example 1: Add 20% VAT
Input
Net $100, rate 20%, add
Result
Gross $120.00 (VAT $20.00)
Why
100 × 1.20 = 120; the VAT portion is 100 × 0.20 = 20.
Example 2: Remove 20% VAT
Input
Gross $120, rate 20%, remove
Result
Net $100.00 (VAT $20.00)
Why
120 ÷ 1.20 = 100, so the included VAT was 20.
Example 3: Different rate
Input
Net $200, rate 7.5%, add
Result
Gross $215.00 (VAT $15.00)
Why
200 × 0.075 = 15 VAT, total 215.

When to use this tool

  • Adding VAT/GST to a quote or invoice from a net price.
  • Finding the net price and tax inside a VAT-inclusive total.
  • Checking the tax portion of a purchase.

Common mistakes

  • Removing VAT by subtracting the rate (gross × 0.8) instead of dividing by 1.2 — that under-states the net.
  • Using the wrong country's rate; VAT/GST rates differ widely and some goods are zero-rated or exempt.
  • Forgetting that consumer prices in many countries are already VAT-inclusive (gross), so you should 'remove', not 'add'.

Frequently asked questions

How do I add VAT to a price?

Multiply the net price by 1 plus the rate. At 20%, multiply by 1.20. The tax amount alone is the net price times the rate (0.20).

How do I remove VAT from a total?

Divide the gross (VAT-inclusive) price by 1 plus the rate. At 20%, divide by 1.20 to get the net; the difference is the VAT.

Is VAT the same as GST or sales tax?

VAT and GST work similarly (tax collected at each stage, shown in the price). U.S. sales tax is added at checkout instead. The math here applies to VAT and GST; use your local rate.

What VAT rate should I use?

Use your country's standard rate, or the reduced/zero rate for specific goods. Rates vary by jurisdiction and product, so check your local tax authority.
