How VAT Calculator works

The selected net or gross mode determines how the VAT factor is applied.

For a net input, the amount is multiplied by one plus the VAT rate to obtain gross. For a gross input, it is divided by that same factor to recover net. The difference between gross and net is the VAT amount.

Enter the VAT rate yourself. Tax treatment, exemptions, and invoice rounding depend on jurisdiction.

Conceptual reversible conversion between net and gross prices with a VAT component.
Adding and removing VAT use different directions of the same rate factor.

How to use VAT Calculator

Choose whether the entered amount is before VAT or already includes it.

Set the amount, rate, and mode

Enter the amount and VAT percentage, then choose whether the amount is Before VAT or After VAT. Check the mode before calculating because the same number can represent a net price or an already-taxed gross price.

Calculate the net and gross prices

Select Calculate and read the price including VAT. The page multiplies a net input by one plus the rate or divides a gross input by that factor. Removing VAT does not simply subtract that percentage directly from gross.

Review the VAT breakdown

Read Net price, VAT amount, and Gross price together to see how the input was interpreted. Rates, exemptions, tax treatment, and invoice rounding depend on the applicable rules. The form supplies arithmetic for one amount rather than a compliant invoice.

Calculations for a stated VAT rate

Keep net and gross amounts clearly labelled when moving results into an invoice check.

Add VAT to a net amount

A hypothetical net amount of $100 at twenty percent becomes $120 gross, including $20 of VAT. Select the before VAT mode for this direction. The example supplies a rate for arithmetic and does not establish tax treatment for a transaction.

Extract VAT from a gross amount

Enter $120 with the same twenty percent rate and select the after VAT mode. The net amount is $100 and VAT is $20. Subtracting twenty percent of the gross would use a different basis and would not reproduce this breakdown.

Check a labelled invoice line

Use one invoice amount with its stated net or gross basis and rate to inspect the arithmetic. For an invoice with multiple rates, examine the relevant lines separately. The form has one rate and does not reconstruct a whole mixed rate invoice.

Why extracting VAT uses the gross basis differently

Read the recovered net amount, tax component, and gross price together.

A VAT inclusive amount contains the net price plus VAT calculated from that net price. The after VAT mode divides by the corresponding factor to recover net, then shows the difference as VAT.

The main result remains Price including VAT even when the input was already gross. Use the labelled breakdown to find the extracted net amount. Displayed money is rounded and does not determine invoice or jurisdiction rules.

Check mode and local treatment

Confirm input mode and rate before comparing against an invoice.

Before and after VAT are calculation directions, not tax eligibility choices. If an entered amount is already gross, selecting the net mode adds VAT again. Confirm the amount basis before deciding that the displayed total is wrong.

Exemptions, jurisdiction treatment and invoice rounding can differ from this one amount model. The page does not decide the applicable rate or produce a tax invoice. Keep any real transaction checks tied to the relevant information.

VAT Calculator: common questions

Answers about using VAT Calculator and understanding its results.

How do I remove VAT?

Choose After VAT (gross); the tool divides the gross amount by one plus the VAT rate.

Does this know the current VAT rate?

No. Rates vary by place and product, so enter the applicable rate.

Is removing VAT the same as subtracting the percentage from gross?

No. Removing VAT divides gross by one plus the rate. Subtracting the rate directly from gross would use a different percentage basis.

Does this create a compliant VAT invoice?

No. It supplies arithmetic for one amount and rate. Invoice content, tax treatment, and rounding depend on the applicable rules.
