How to Calculate VAT in the UK
Standard VAT Calculation Formula
There are two main ways to calculate VAT:
- From Net to Gross:
VAT = Net Price × (VAT Rate / 100)
Gross Price = Net Price + VAT - From Gross to Net:
VAT = Gross Price × (VAT Rate / (100 + VAT Rate))
Net Price = Gross Price – VAT
These are the core formulas you’ll see behind any VAT calculator, whether online or manually built. The Online VAT Calculator UK applies these automatically.
How is VAT Calculated?
VAT Rates in the UK:
- Standard rate: 20%
- Reduced rate: 5% (e.g., energy bills)
- Zero rate: 0% (e.g., children’s clothing, basic food)
Example 1: Add VAT to Net
- Net price: £100
- VAT (20%): £20
- Gross price: £120
Example 2: Subtract VAT from Gross
- Gross price: £120
- VAT (20%): £20
- Net price: £100
The formulas ensure consistency in invoices and tax reporting, and they are the basis of most online VAT calculators, including the Online VAT Calculator UK.
How to Calculate VAT from Gross Amount
To find VAT from a gross figure:
VAT = Gross × (VAT Rate / (100 + VAT Rate))
Example:
- Gross: £240
- VAT Rate: 20%
- VAT = 240 × (20/120) = £40
- Net = £200
This reverse method is useful when the price already includes VAT. The Online VAT Calculator UK automates this effortlessly.
How to Calculate VAT in Excel
To Add VAT:
- Formula: =A1*20%
- Example: =100*20% = 20
To Subtract VAT:
- Formula: =A1-(A1/(1+20%))
- Example: =120-(120/1.2) = 20
Excel is handy for bulk VAT calculations but is prone to user error. The Online VAT Calculator UK is more reliable and faster.
How to Reverse Calculate VAT
Reverse calculation helps when you’re given a total (gross) that includes VAT.
Formula:
VAT = Gross × (VAT Rate / (100 + VAT Rate))
Example:
- Gross: £120
- VAT Rate: 20%
- VAT = £20, Net = £100
Online VAT Calculator UK supports both normal and reverse VAT calculations.
How to Calculate VAT on a Calculator
Steps:
- Convert VAT rate into decimal (e.g., 20% = 0.20)
- Multiply net price by VAT rate
- Add result to net price
Example:
- Net: £100
- VAT = 100 × 0.20 = £20
- Gross = £100 + £20 = £120
Manual calculators work, but using the Online VAT Calculator UK is faster and error-free.
How to Calculate VAT Return
A VAT return is a report submitted to HMRC summarising the VAT collected and paid.
You’ll need:
- VAT charged on sales (output tax)
- VAT paid on purchases (input tax)
Formula:
VAT to pay/refund = Output VAT – Input VAT
An Online VAT Calculator UK helps determine accurate VAT figures for your return. It can also help create supporting documentation.
How to Calculate Flat Rate VAT
The Flat Rate Scheme allows small businesses to pay VAT as a fixed percentage of turnover.
Steps:
- Identify flat rate for your sector
- Multiply gross turnover by flat rate
Example:
Turnover: £50,000, Flat rate: 12%
VAT due = £50,000 × 12% = £6,000
Note: Businesses under this scheme still charge standard VAT but pay HMRC the flat rate. The Online VAT Calculator UK simplifies flat-rate computations.
How to Calculate Import VAT and Duty in the UK
Import VAT is calculated on the total value of imported goods.
Formula:
Import VAT = (Customs value + Duty + Shipping) × VAT Rate
Example:
- Customs value: £1,000
- Duty: £100
- Shipping: £50
- VAT Rate: 20%
- Import VAT = (£1,150) × 20% = £230
The Online VAT Calculator UK is useful for quickly estimating this, although HMRC has its own import calculators as well.
