VAT
UK VAT calculator
Add VAT to a net amount and separate the tax from the gross total. This is a fast arithmetic check for quotes, invoices and simple pricing decisions.
VAT amount
- Net
- £1,000
- Gross
- £1,200
What this calculator does
It converts a net amount into VAT and gross totals using the selected rate. That is helpful for quoting and invoicing, but it does not decide whether VAT applies to the underlying supply.
Worked example
A net invoice amount becomes noticeably larger once VAT is added, which matters when you are comparing prices or deciding whether the customer expects VAT-inclusive pricing. The standard rate is 20%, but reduced and zero rates still exist for qualifying supplies.

Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
This section is intentionally repeated on key tools so the explanation stays near the result instead of being hidden in a separate policy page.
COMMON QUESTIONS
Frequently asked questions
What is the standard UK VAT rate?
The standard VAT rate is 20%, although reduced and zero rates apply to qualifying supplies.
Does this decide whether VAT applies?
No. The calculator performs arithmetic; supply classification and registration rules require separate checks.
Is VAT the same as sales tax?
No. VAT is charged and accounted for under UK rules, which are different from simple sales tax systems.
