VAT calculator: add, extract, and spell out the amount

The field is empty: paste your amounts here, and a table with the total will appear.

This table includes only the standard rate. Reduced, preferential, and zero rates are excluded: each country has several, and they do not apply to every transaction. Rates change — check local law or consult an accountant before making a deal.

How to use it

1. Enter the amount exactly as it appears in the document

   Spaces between digit groups and the comma in the fractional part are parsed automatically. The label above the field tells you which amount is required in the selected mode.

2. Select a mode

   “Add VAT” means the field contains the price before tax. “Extract VAT from the total” means VAT is already included. “Known VAT amount” means the field contains the VAT itself, and the calculator restores the base and total—useful for checking someone else’s invoice when only the VAT line balances.

3. Set the rate

   The 22, 20, 10, 7, 5, and 0 buttons cover common rates. “Custom” accepts any value from 0 to 100, including fractional values. If you are calculating for another country, select it from “select a country rate.” There are 74 entries, and the currency will be filled in along with the rate if it is one of the four supported currencies.

4. Choose rounding

   “To kopecks” matches an invoice. “To whole units” matches an estimate. The numbers are adjusted to match one another, so the base plus the tax always equals the displayed total exactly, with no one-kopeck discrepancy.

5. Copy the amount in words

   Two ready-to-use lines appear below the total: the VAT-inclusive amount and the VAT amount written in words, with kopecks or cents. This is usually why people enter the amount in the first place: copy the line into an invoice or act.

6. Use the list when you have many items

   The “Calculate a list” section accepts up to fifty amounts, one per row, with a description and its own rate for each. The total row adds up the columns, and the “Download CSV” button provides a file for Excel and Google Sheets.

7. Save or share

   “Calculation link” copies an address to the clipboard that opens with your numbers already entered. “Print” sends a page to the printer or PDF without input fields—only the result. The ten most recent calculations remain in the history on this device.

The formula and what it includes

• Amount — the value in the field. “Add VAT” means the price before tax, “VAT included” means the price including tax, and in the third mode it means the VAT amount itself
• Rate — 22, 20, 10, 7, 5, or 0 percent, selected with a button; “custom” accepts any value from 0 to 100, including fractional values
• Effective rate — the fraction Rate ÷ (100 + Rate), expressed as a percentage: the share of VAT in the VAT-inclusive amount. For 22%, this is 22/122 = 18.03%
• Amount excluding VAT — the base used to calculate the tax
• VAT-inclusive amount — the amount paid by the buyer

Example breakdown: amount 100,000 at a 22% rate

The input data is the same as the default field values: you can calculate it mentally and confirm that the tool is telling the truth.

• Amount: 100,000 rubles
• Rate: 22%
• Mode: “Add VAT”
• Rounding: to kopecks

1. VAT: 100,000 × 22 ÷ 100 = 22,000.

2. VAT-inclusive amount: 100,000 + 22,000 = 122,000.

3. In words: one hundred twenty-two thousand rubles 00 kopecks—this line goes on the invoice.

4. Now calculate it in reverse. Enter 122,000 and switch the mode to “Extract VAT from the total.”

5. VAT: 122,000 × 22 ÷ 122 = 22,000. The amount excluding VAT is 122,000 − 22,000 = 100,000.

6. Third check: enter 22,000 and select “Known VAT amount.” Base: 22,000 × 100 ÷ 22 = 100,000; total: 122,000.

The tax is the same in all three cases—22,000. The only difference is what it is calculated from: when VAT is added, it is 22% of 100,000; when VAT is extracted, it is 22/122 of 122,000; and in reverse, the base is restored from the tax amount itself. The currency does not affect the calculation; it labels the numbers and selects the words for the amount in words.

Frequently asked questions

• What is the difference between “VAT included” and “VAT on top”?

  It depends on which amount is used as the base. “Add VAT” means the contract lists the price before tax, and the buyer will pay the tax on top. “VAT included” means the price is final, and the tax is extracted from it. At a 22% rate, the difference is significant: adding VAT to 100,000 gives 22,000, while extracting it from the same 100,000 gives 18,032.79.

• Why is there a “known VAT amount” mode?

  This is useful when only the VAT line is clear in a document, while the base and total are uncertain—for example, in a contractor’s invoice or a statement. Enter the VAT amount and select the rate—the calculator will restore both the base and the total. This mode does not work at a 0% rate: you cannot derive the base from zero, and the calculator will tell you so.

• What is the effective rate, and where does 18.03% come from?

  This is the share of VAT in the VAT-inclusive amount: the rate divided by 100 plus the rate. For 22%, that is 22/122, or 18.0327…—rounded to 18.03%. For 20%, it is 16.67%; for 10%, 9.09%. The value appears as a separate line in the panel because invoices and accounting registers use this exact figure.

• Why do you divide by 120 instead of 100 when extracting VAT?

  Because the tax-inclusive amount is 120% of the base: 100% of the price plus 20% tax. To find the 20%, you need to take 20/120 of the total amount. At a 22% rate, the tax-inclusive amount is 122%, so the fraction is 22/122; at 10%, it is 10/110.

• Which rate should I use?

  Use the rate shown in your document. The 22, 20, 10, 7, 5, and 0 buttons cover common values so you do not have to type them. 22 is Russia’s standard rate from 2026, 20 is the former standard rate and the current standard rate in many countries, 10 is a reduced rate for food, medicine, and children’s goods, and 5 and 7 are rates for the simplified tax system, where VAT has been charged since 2025. Enter any other value under “custom,” including fractional rates such as 8.1 or 25.5.

• Where did the rates in the country list come from?

  These are the standard rates as of early 2026—74 countries, from 5% in the UAE and Canada to 27% in Hungary. Reduced and preferential rates are not included: each country has several of them, and they do not apply to every transaction. Rates can change, sometimes during the year, so check local law before a transaction. The list saves you from searching for the figure; it is not a substitute for professional advice.

• Does the currency affect the calculation?

  No. The currency does not affect the arithmetic, and the calculator does not convert currencies. It labels the numbers and selects the words for the amount in words: rubles and kopecks, hryvnias and kopecks, dollars and cents, euros and cents. If a country in the list uses another currency, it will remain unchanged, and a note below the list will show which currency is used there.

• How is the amount written out in words?

  The whole-number part is written in words and the fractional part in digits: “one hundred twenty-two thousand rubles 00 kopecks.” This is how amounts are written in invoices and acts. Grammatical gender is handled correctly: “one” and “two” for rubles and dollars, and “one” and “two” in the feminine form for hryvnias and thousands. The word “euro” does not decline. When rounding to whole units, the kopecks disappear from the line.

• Do the base, tax, and total balance to the cent?

  Yes, deliberately. The calculator rounds according to the selected mode and adjusts the third value to match the other two, so the total balances. If each value were rounded separately, the invoice could be off by one kopeck. The amount by which rounding changed the exact value is shown below the lines written in words.

• What does a 0% rate mean?

  This is a rate, not an absence of tax: the transaction is taxable, but the tax amount is zero. It still needs to be calculated, and the calculator will correctly show zero. Which transactions qualify for a zero rate is a matter for local law and an accountant; the calculator does not select the rate.

• How do I calculate many rows at once?

  The “Calculate a list” section accepts up to fifty amounts, one per row. A plain number uses the rate selected in the panel. “Office rent; 85 400.50” includes a description. “Delivery; 3200; 10” uses its own rate. Columns copied from Excel are inserted as is, with tabs as separators. The bottom row shows the total for all rows, and the “Download CSV” button provides a file that opens in Excel and Google Sheets.

• Is any data sent anywhere?

  No. Everything is calculated in the browser: after the page loads, it makes no requests, which you can see in the developer tools’ “Network” tab. A calculation link is simply an address with numbers in its parameters, generated on your device. The history of recent calculations is stored in the browser and can be cleared with the button.
