VAT Calculator

Add VAT to a price before tax, or work backwards from a price that already includes it. Enter the VAT rate you want to check; the calculator shows all three amounts and explains its rounding.

Price and rate

Calculation

Add VATRemove included VAT

Currency

Changing currency keeps the typed numbers; it does not convert them or choose a rate.

Amount before VAT

Enter 0–1,000,000. EUR allows 2 decimal places.

VAT rate (%)

Enter your percentage from 0 to 100, with up to four decimal places. For 20%, enter 20.

Use a dot or comma as the decimal separator, without grouping. For example, 1,000 is 1.000 in KWD, invalid as EUR money, and 1% as a rate—not one thousand.

Result

Enter a price and your VAT rate, then calculate.

Calculation method

The calculation stays in your browser; this tool does not upload or save prices or rates. Copy uses your clipboard only when requested. Other site services follow the privacy policy.

Check a price with or without VAT

Choose Add VAT for a price that excludes tax, or Remove included VAT for a price that already contains it. Each direction keeps its own typed price, while the rate is shared.
Select the currency, enter the price without thousands separators and supply the percentage number. For 20%, type 20. A dot or comma can mark the decimal part; the rate allows up to four decimal places.
Calculate and check the before-VAT amount, VAT and inclusive total. Copy keeps the direction, rate and rounding explanation with the figures. Editing a field removes the previous result.

Adding VAT is not the same as removing it

Adding 20% VAT to a price of 100 gives VAT of 20 and a total of 120. When 120 already includes that tax, divide by 1.20 to recover the exact price before VAT. Subtracting 20% of 120 would give 96, which is a different calculation.

For an inclusive amount, the included VAT fraction is the rate divided by 100 plus the rate. At 20%, that fraction is one sixth of the total, not one fifth. The calculator applies the rate you enter; it does not determine which rate or treatment applies to a purchase.

VAT is rounded once to the currency's supported minor unit, with exact halves rounded up. The other price is then found by addition or subtraction, so the displayed amounts balance. Currency precision can be zero, two or three decimal places; this is not special cash rounding.

Changing currency keeps your typed numbers and interprets them in the new currency. It does not convert money, change the VAT rate or select a country's rules. Changing language affects presentation, not the calculation or tax treatment.

Useful checks and small-amount surprises

For a EUR 100 price before VAT and an illustrative 20% rate, the result is EUR 20.00 VAT and EUR 120.00 including VAT. Removing included 20% VAT from EUR 120 gives the same three amounts before any difficult rounding arises.

An inclusive EUR 0.03 amount at 20% has exact VAT of EUR 0.005. This calculator rounds VAT to EUR 0.01 and leaves EUR 0.02 before VAT. Independently rounding the exact before-VAT amount to EUR 0.03 would make the displayed figures add to the wrong total.

At 20%, three separate EUR 0.03 prices each round to EUR 0.01 VAT, giving EUR 0.12 combined. Calculating once on their EUR 0.09 sum gives EUR 0.02 VAT and EUR 0.11 total. Line-by-line and aggregate rounding can differ; this single-amount calculator does not decide an invoice's required method.

A price estimate, not a tax decision

Use a rate and price basis you have checked for your situation. This tool does not look up current rates, decide exemptions or reverse charges, establish registration or reclaim eligibility, or prepare an invoice or tax return. A zero entered rate is only a calculation input.

The price limit is 1,000,000 in the selected currency and the rate limit is 100%, with up to four decimal places. These software bounds are not recommendations. Only one nonnegative amount and one rate are included; mixed-rate lines, refunds, discounts, shipping adjustments and currency exchange are outside the calculation.

A positive exact tax can round to zero; at a very small inclusive price, tax-first balancing can also leave a displayed before-VAT amount of zero. Separate notes explain those cases. Reversing a rounded result is not guaranteed to reproduce the original input, and an invoice using another permitted rounding method can differ.

Your price calculation

VAT calculation questions

The inclusive price already contains the original price plus 20% of that original price. Divide the inclusive total by 1.20 to find the exact exclusive price; the included VAT is one sixth of the total. A 20% discount uses a different base.

Enter the percentage you have established for your particular transaction. The calculator does not choose a rate from your language, location or currency. Its 20% example illustrates arithmetic, not a recommendation or a current rate lookup.

It rounds VAT once to the selected currency's minor unit, with exact halves upward. In Add mode it adds that tax to your exclusive price; in Remove mode it subtracts it from your inclusive price. It does not round both independently and then allow a mismatched total.

Invoices can apply different permitted rounding conventions or round each line instead of the aggregate amount. This calculator uses one disclosed tax-first convention for one price and rate. It does not certify an invoice, tax return or legally required tax amount.

No. The same typed numbers are checked against the new currency's precision, without exchange or a tax-rate change. A two-decimal price must be re-entered if the selected currency permits no decimal places. Language changes presentation only.

A positive tax smaller than half a minor unit rounds to zero. At an inclusive price of EUR 0.01 and a 100% input rate, the exact half-cent tax rounds to EUR 0.01, leaving EUR 0.00 before VAT under tax-first balancing. The adjacent note identifies the case; this is not a tax-exemption decision.
