VAT Calculator

About the VAT Calculator

A VAT calculator (Value Added Tax calculator) adds VAT to a net price to get the gross (VAT-inclusive) price, or removes VAT from a gross price to find the net price and the VAT amount separately. VAT is the primary sales tax system used in over 160 countries including all European Union member states, the UK, Australia (GST), Canada (GST/HST), and most of Asia and Africa. Unlike US sales tax which is added at the final point of sale, VAT is collected at each stage of the supply chain, with businesses reclaiming VAT paid on purchases (input VAT) against VAT charged on sales (output VAT). Our free VAT calculator handles both directions: adding the specified rate to a net amount to calculate the gross price (for pricing products and services), and extracting the VAT from a VAT-inclusive gross price (for reconciling invoices and calculating input VAT reclaim amounts). Standard EU VAT rates range from 17% (Luxembourg) to 27% (Hungary); UK standard VAT is 20%; Australian GST is 10%.

How It Works

Adding VAT to net price: Gross = Net x (1 + VAT rate/100). VAT amount = Net x (VAT rate/100). Example: £450 net at 20% UK VAT: VAT = £450 x 0.20 = £90. Gross = £450 + £90 = £540. Or: Gross = £450 x 1.20 = £540. Removing VAT from gross price: Net = Gross / (1 + VAT rate/100). VAT amount = Gross - Net. Example: receipt shows €660 VAT-inclusive at 10% GST: Net = €660 / 1.10 = €600. VAT = €660 - €600 = €60. Note: dividing by (1 + rate) is NOT the same as multiplying by (1 - rate). To remove 20% VAT from £540: £540 / 1.20 = £450. Incorrectly calculating £540 x 0.80 = £432 — a common mistake that gives the wrong answer.

Tips & Best Practices

• ✓The "divide, not subtract" rule: to remove 20% VAT from a gross price, always divide by 1.20 — never multiply by 0.80. The two produce different results because the VAT rate applies to the net price, not the gross.
• ✓Reduced VAT rates: most VAT systems apply reduced rates to essential goods. UK: 5% on domestic energy and children's car seats; 0% on most food, children's clothing, and books. EU: member states set reduced rates (typically 5-10%) for food, pharmaceuticals, and cultural items.
• ✓VAT registration threshold: in the UK, businesses must register for VAT when annual taxable turnover exceeds £85,000 (2024/25). Below this threshold, you can register voluntarily to reclaim input VAT on purchases.
• ✓Business VAT reclaim: VAT-registered businesses reclaim input VAT paid on eligible business purchases by filing regular VAT returns. The calculator helps identify the reclaimable amount from supplier invoices.
• ✓Invoice requirements: a valid VAT invoice must include the supplier's VAT registration number, the VAT rate applied, the net amount, the VAT amount, and the gross total — all clearly itemised. Without a valid invoice, input VAT cannot be reclaimed.
• ✓Reverse charge mechanism: for B2B services across EU borders, the customer (not supplier) accounts for VAT under the reverse charge mechanism. This avoids foreign suppliers needing VAT registration in every EU country.
• ✓GST in Australia: 10% GST applies to most goods and services. Fresh food, medical services, and educational courses are GST-free. Financial services use input taxation. The Australian BAS (Business Activity Statement) reports GST collected and paid.
• ✓Canada GST/HST: 5% federal GST applies nationwide; provinces with HST (Ontario 13%, Nova Scotia 15%) combine provincial and federal taxes. Quebec applies QST separately alongside GST.
