VAT / Tax Calculator
Example 1
A product costs $100 before 20% VAT is applied. You need the total price including tax.
Solution
VAT amount = $100 x 0.20 = $20
Total including VAT = $100 + $20 = $120
Answer
$100 + $20 VAT = $120 total. VAT adds 20% to the base price.

Example 2
A product is priced at $180 including 20% VAT. You need to find the pre-VAT price and the VAT paid.
Solution
Pre-VAT price = $180 / 1.20 = $150
VAT paid = $180 - $150 = $30
Answer
$180 total at 20% VAT = $150 base + $30 VAT. Reverse calculation: divide by 1.20.

Example 3
A VAT-registered business incurs a $500 expense subject to 20% VAT.
The total invoice is $600 ($500 + $100 VAT). Whether the VAT is reclaimable changes the net cost.
Solution
If VAT is reclaimable: net cost = $500 (the VAT is recovered from the tax authority)
If VAT is not reclaimable: net cost = $600 (the VAT is a real expense)
Difference = $100 = 20% of the expense amount
Answer
Reclaimable: $500. Non-reclaimable: $600. VAT registration saves $100 on this expense.

Example 4
A laptop costs €249.99 in Germany (19% VAT). What is the net price, VAT amount, and UK price at 20% VAT?
Solution
VAT = €249.99 - €210.08 = €39.91 (also €210.08 × 0.19 ≈ €39.92).
UK gross at 20% = €210.08 × 1.20 = €252.10.
Answer
Net: €210.08, VAT: €39.91, Gross: €249.99.

Frequently Asked Questions
VAT (Value-Added Tax) is a consumption tax applied at each stage of the supply chain where value is added. Businesses charge VAT on their sales (output tax) and reclaim VAT on their purchases (input tax). The final consumer bears the full cost because they cannot reclaim the tax. For example, a manufacturer sells to a wholesaler for $100 plus $20 VAT, the wholesaler sells to a retailer for $200 plus $40 VAT and reclaims the $20 paid, remitting only $20 to the tax authority. The retailer sells to the consumer for $300 plus $60 VAT and reclaims $40, remitting $20. The government collects $60 total, and the consumer pays $360.
Sales tax is collected only at the final point of sale to the end consumer. Businesses generally do not pay sales tax on their purchases because they are not the final consumer. VAT is collected at every stage of the supply chain, with businesses reclaiming input tax on their purchases. Both systems collect roughly the same total tax on the final sale price, but VAT creates a transaction trail at every stage that makes evasion more difficult. The United States uses sales tax; most other countries use VAT, including all European Union member states, Australia, Canada (GST), India, Japan, and South Korea.
Use Add mode when you know the net price (price before tax) and need to calculate the tax amount and the gross total including tax. This is common when preparing invoices for business customers. Use Extract mode when you have a total price that already includes tax and need to find the net price and the tax amount. This is common when reviewing supplier invoices, claiming input tax credits, or comparing prices from VAT-inclusive countries. Select the mode that matches the information you have, and the calculator handles the rest.
Using Extract mode when you have a net price will understate the tax. If you enter $100 net at 20% in Extract mode, the calculator treats $100 as the gross total and returns $83.33 net and $16.67 tax, instead of the correct $120 gross and $20 tax. Using Add mode when you have a gross price will overstate the tax. If you enter $120 gross at 20% in Add mode, the calculator returns $144 gross and $24 tax, instead of the correct $100 net and $20 tax. Always confirm whether your entered price includes or excludes tax before choosing the mode.
Make separate calculations for each rate category. Enter the total value of items at the first rate and calculate, then repeat for each additional rate, and sum the results. For example, in the UK, if your invoice has £500 of standard-rated goods (20% VAT) and £200 of reduced-rate goods (5% VAT), calculate £500 plus 20% to get £100 tax and £600 total, then calculate £200 plus 5% to get £10 tax and £210 total. The combined totals are £110 tax and £810 total.
Tax amounts are typically rounded to the nearest cent (two decimal places). On multi-line invoices, each line item's tax is rounded individually before summing. The sum of rounded line-item taxes may differ by one or two cents from the tax calculated on the subtotal. Most tax authorities accept this discrepancy within reasonable tolerance. This calculator rounds each calculation to two decimal places, giving you the amount that should appear on a single-line invoice or receipt.
VAT registration thresholds vary by country. In the UK, you must register if your taxable turnover exceeds £90,000 in any 12-month period. In Germany, the threshold is €22,000 for the previous year and €50,000 for the current year. In Australia, GST registration is required if your business turnover exceeds AUD 75,000. In most countries, you can voluntarily register below the threshold, which allows you to reclaim input tax on business purchases. This calculator helps you understand the arithmetic of VAT but does not determine your registration requirements. Consult your local tax authority or a qualified accountant for registration advice.
Exports are generally zero-rated, meaning you charge 0% VAT and can still reclaim input tax on related purchases. Imports are subject to VAT at the rate of the destination country, collected by customs at the border. For services imported from another country, the reverse charge mechanism applies: the recipient accounts for the VAT rather than paying it to the foreign supplier. VAT on imports must be paid before the goods are released from customs, though some countries allow businesses to defer the payment or account for it on their VAT return. This calculator handles the basic arithmetic for any rate scenario.
VAT return frequency varies by country and business size. In the UK, most businesses file quarterly returns. In Germany, returns are filed monthly for the first year and quarterly thereafter for most businesses. In Australia, GST returns are filed quarterly, with monthly or annual options available. Late filing carries penalties in most jurisdictions, including automatic surcharges, interest on unpaid tax, and daily filing penalties. Some countries now require digital filing through government portals. Use this calculator to verify your tax amounts before filing to ensure accuracy.
Yes, if you are VAT-registered and the purchases are for use in your taxable business activities. The VAT you pay on purchases (input tax) is deducted from the VAT you collect on sales (output tax) when you file your VAT return. If your input tax exceeds your output tax in a period, the tax authority typically refunds the difference. You must hold valid tax invoices from your suppliers showing the VAT amount to support each reclaim. Certain purchases, such as entertainment expenses and motor cars with private use, may have restrictions on input tax recovery. This calculator helps verify the VAT amounts on your supplier invoices before claiming them.
The VAT Flat Rate Scheme is a UK-specific simplification available to businesses with turnover under £150,000. Instead of calculating input and output tax separately, the business pays a fixed percentage of its VAT-inclusive turnover to HMRC. The percentage varies by industry: 2% for food retailers, 6.5% for hotels, 8.5% for restaurants, and 14.5% for accountants. The business still charges customers 20% VAT on invoices but remits only the flat rate percentage to HMRC. For most businesses, this reduces the VAT administration burden but results in slightly higher VAT payments than the standard scheme.
Set the tax rate to 0%. The calculator will show the price excluding tax equal to the price including tax, with zero tax amount. Non-taxable or exempt supplies include most financial services, insurance, education, healthcare, and postal services in many countries. For zero-rated supplies, the rate is also 0% for the consumer, but the supplier can reclaim input tax on related purchases. For exempt supplies, the supplier cannot reclaim input tax. The calculator treats both the same way since the arithmetic is identical.
Yes, select your desired currency from the dropdown. The calculator supports 180+ currencies and displays results with the correct currency symbol using Intl.NumberFormat. The calculation itself is independent of the currency: multiply the price by the tax rate percentage, regardless of whether the price is in USD, EUR, GBP, JPY, or any other supported currency. This is useful for businesses that invoice in multiple currencies and need to show VAT amounts in the invoice currency.
Yes. In B2B transactions, the buyer can generally reclaim the VAT as input tax, so the VAT is effectively a cash flow item rather than a cost. In B2C transactions, the consumer cannot reclaim the VAT, so it becomes a real cost. The place of supply rules also differ: B2B services are generally taxed where the customer belongs, while B2C services are taxed where the supplier belongs. For cross-border transactions within the EU, B2B services use the reverse charge mechanism, while B2C digital services are taxed in the customer's country under the One-Stop Shop system.
During a VAT audit, the tax authority may select a sample of your sales and purchase invoices and recalculate the VAT amounts. Using this calculator to independently verify the amounts on your invoices before the audit helps you identify and correct errors before they are discovered by the auditor. Discrepancies of a few cents are typically ignored, but systematic errors at the wrong rate or using the wrong mode can trigger a full audit and substantial penalties. Regular use of an independent calculator as a verification tool is a recommended internal control practice for any VAT-registered business.
