VAT calculator

The VAT calculator splits one amount into net, value-added tax, and gross at the rate you pick. From 1000 net at 20%, a common invoice rate, the tax is 200 and the amount due is 1200. From a receipt, choose Gross → Net and divide by 1.20. You can still type 23 or another rate.

Rate arithmetic only, no tax ID and no filing file. 1000 net at 20% yields 200 tax. Take-home pay lives on net to gross pay. Article: net, tax, and gross.

How results are calculated

VAT, value-added tax, is three numbers from one amount on this page: net, the tax itself, and gross. You pick a direction, type an amount, and set a rate. At 20%, net times 1.20 is gross. At 10% the multiplier is 1.10. Zero percent makes net equal gross in this model, because the formula knows a rate, not a legal exemption.

The service-quote card uses 1000 net and 20%. Tax is 200 and the client sees 1200 due. From a 2400 receipt at the same rate you get back to 2000 net and 400 VAT, because 2400 divided by 1.20 is exactly 2000. At 500 net and 10%, tax is 50 and gross is 550.

Direction is a list, not a number field: Net → Gross or Gross → Net. Type the amount in the sense you chose. VAT rate (%) starts at 20. Under common rates you can drop in 20, 10, 5, or 0, or keep a custom rate and type another. Click Calculate and read the three cards plus the bars.

A paycheck with a percent wedge is on the neighbouring page, on net to gross pay. That rate is your sketch of wage tax, not invoice VAT. A two-bracket income-tax sketch is on the income tax page. The three tools keep separate fields.

The result is pure arithmetic. There is no date, tax ID, or filing export. 0% on the calculator does not decide whether a sale is exempt. For bookkeeping use a ledger or an accountant, not the rate slider alone.

A comma and a period in the amount mean the same thing. Type 1000, leave 20, click Calculate, and check 200 and 1200. Then reverse 1200 to get back to 1000.

How to use the calculator

  1. In Direction, choose Net → Gross when you know the pre-tax amount, or Gross → Net when you have a receipt.
  2. In Amount, type that one number. For the first direction it is net; for the second it is gross.
  3. In VAT rate (%), leave 20 or type another. Presets 20, 10, 5, and 0 sit under common rates.
  4. Click Calculate. Read net, VAT, and gross. At 1000 and 20% you should see 200 and 1200.
  5. Check the bars beside the form. Then reverse 1200 to see that you divide by 1.20.

VAT, net, and gross on this invoice card

The calculator splits an amount at the VAT rate you type. 1000 net at 20% is 200 tax and 1200 gross. From a 2400 receipt at 20% you get back 2000 net.

VAT
Value-added tax in this calculator. 1000 net at 20% is 200 VAT. This is not a paycheck wedge.
net
The amount before VAT. Net to gross at 1000 and 20% pays 1200. 2400 gross at 20% returns 2000 net.
gross
The amount with VAT. 1000 + 200 = 1200 at 20%. At 10% the same 1000 net becomes 1100 gross.
rate
The VAT rate (%) field, default 20. At 10% on 500 net, tax is 50 and gross is 550.

Usage examples

Example 1

  • Direction: net → gross
  • Net amount: 1000
  • Rate: 20%

Tax 200
Gross 1200

Typical pre-tax quote: the client pays 1200, while your invoice lines show net 1000 plus tax 200.

Example 2

  • Direction: gross → net
  • Gross amount: 2400
  • Rate: 20%

Net 2000
Tax 400

When you only know the payable total, dividing by 1.20 separates the base from the tax wedge.

Example 3

  • Direction: net → gross
  • Net amount: 500
  • Rate: 10%

Tax 50
Gross 550

At a reduced rate the gross-net gap shrinks. Useful before comparing tax-included vs tax-excluded offers.

How much VAT is due on 1000 net at 20%?

200 tax and 1200 gross. 1000 × 0.20 = 200, and 1000 + 200 = 1200.

How do I recover net from 1200 gross at 20%?

How is Direction different from Amount?

Direction is a list: net to gross or gross to net. Amount is one number that direction interprets.

Does 0% VAT mean the sale is exempt?

In this formula VAT = 0 and gross = net. A legal exemption and a 0% rate are different regimes. The calculator only applies the rate.

Can I book this into a tax return file?

No. There is no tax ID, date, or transaction type. This is a quick amount splitter, not a ledger.

How is this different from net to gross pay?

Here you have invoice VAT. There you have a percent wage wedge: tax, optional social charges, and a flat other amount. Different fields, different formula.

Why does the rate start at 20%?

That is the default typed value, a common invoice rate. You can type 23, 10, 5, 0, or any other rate.

Does the header currency multiply 1200?

No. 1200 stays 1200. The symbol only labels the same number.

How do I get gross from net at 5%?

Net × 1.05. From 1000 net, VAT is 50 and gross is 1050. From 500 at 10% the result is 550.
