Start Your Free TrialHow This Calculator Works
This calculator performs two core VAT arithmetic operations based on the mode you select, using the standard UK VAT rates:
Adding VAT (Net to Gross)
Multiplies your net amount by (1 + VAT rate). For the standard 20% rate, this means multiplying by 1.20. A net amount of £1,000 becomes £1,200 gross, with £200 being the VAT element.
Removing VAT (Gross to Net)
Divides your gross amount by (1 + VAT rate). For the standard 20% rate, this means dividing by 1.20. A gross amount of £1,200 gives a net of £1,000 with £200 VAT. A common mistake is subtracting 20% from the gross - this gives the wrong answer.
Three Rate Options
The calculator supports the standard rate (20%) for most goods and services, the reduced rate (5%) for items like home energy and children's car seats, and the zero rate (0%) for essentials like most food, children's clothing, and books.
Worked Example: £10,000 Invoice
You are a VAT-registered IT consultant invoicing a client £10,000 for project work. Here is how VAT applies at the standard 20% rate:
Adding VAT to your invoice
The other direction: extracting VAT from a receipt
You receive a £12,000 gross receipt and need to work out the VAT content:
A common mistake: taking 20% off £12,000 gives £2,400, not £2,000. Always divide by 1.20 (not multiply by 0.80) to extract the correct VAT amount from a gross figure.
When to Use This Calculator
Creating Invoices
Work out the VAT-inclusive total to show on invoices when you know your net fee. Ensures your invoices are compliant with HMRC requirements.
Processing Receipts
Extract the VAT element from gross receipts so you can reclaim input VAT correctly on your VAT return.
Quoting Clients
When clients ask for a price, quickly calculate whether to quote net or gross, and what the total including VAT will be.
VAT Return Preparation
Double-check VAT amounts on transactions before submitting your quarterly or annual VAT return to HMRC.
Important Considerations for 2025/26
VAT Registration Threshold: £90,000
From April 2024 the mandatory VAT registration threshold increased to £90,000. You must register if your VAT taxable turnover exceeds this in any rolling 12-month period, or if you expect it to exceed £90,000 in the next 30 days. The deregistration threshold is £88,000.
Flat Rate Scheme
Small businesses with turnover under £150,000 can join the Flat Rate Scheme, paying a fixed percentage of gross turnover instead of tracking input and output VAT. The percentage varies by industry (e.g., 14.5% for IT consultancy). New businesses get an additional 1% discount in their first year of VAT registration.
Making Tax Digital (MTD)
All VAT-registered businesses are required to keep digital records and submit VAT returns using MTD-compatible software. Paper returns are no longer accepted. Penalties apply for non-compliance under the new points-based penalty system introduced in January 2023.
VAT Return Deadlines
Most businesses submit quarterly VAT returns. Each return is due one month and seven days after the end of the VAT quarter. Late submissions now accrue penalty points, and a £200 penalty is charged once the points threshold is reached.
Reverse Charge Mechanism
If you purchase services from overseas suppliers, the domestic reverse charge may apply. You account for both the output VAT and reclaim input VAT on the same return, resulting in a nil net effect if you are fully taxable. This also applies to certain construction industry services.
