How to add VAT
To add VAT, enter your net price (excluding VAT) and choose your VAT rate. The calculator will show the VAT amount and the gross price (including VAT).
VAT added formula
Gross price = Net price × (1 + VAT rate)
VAT amount = Gross price − Net price
How to remove VAT
To remove VAT, switch the calculator to Remove VAT and enter your gross price (including VAT). The calculator will show the net price and the VAT element.
VAT removed formula
Net price = Gross price ÷ (1 + VAT rate)
VAT amount = Gross price − Net price
Common UK VAT rates
In the UK, different goods and services can fall under different VAT rates. This calculator includes the most commonly used rates and also lets you enter a custom rate.
20% (standard rate)
Often applied to most goods and services. If you’re unsure which rate applies, check your product or service VAT treatment.
5% (reduced rate)
Used for certain items and services where a reduced rate applies. If you regularly charge 5% VAT, this calculator makes it simple.
0% (zero-rated)
Some items may be zero-rated. This calculator will still show the split, but VAT will be £0.00 at 0%.
Custom rate
Useful for special cases, specific industries, or when you’re checking a rate outside the standard options.
VAT on pricing and invoices
If you sell to UK customers and you’re VAT registered, it’s common to show both the net and gross amounts. This helps customers understand what they’re paying and keeps your invoices clear. For many product listings, you may also want to show the VAT-inclusive price to reduce confusion.

Frequently asked questions
Is this calculator suitable for VAT returns?
This VAT calculator is designed for adding and removing VAT on individual prices. VAT returns can involve input VAT, output VAT, partial exemption, reverse charge, and other rules — so you may need additional tools for full VAT return calculations.
Should I add VAT to my prices?
If you’re VAT registered, you’ll usually need to charge VAT on VAT-able sales (unless the supply is exempt or zero-rated). If you’re not VAT registered, you typically shouldn’t charge VAT. If you’re unsure, it’s worth checking your VAT registration status and obligations.
Why is removing VAT not just “take off 20%”?
Because VAT is added on top of the net price. If a gross price includes 20% VAT, the net is found by dividing by 1.2 — it’s not the same as subtracting 20% of the gross.
Can I use this for 5% VAT?
Yes. Select 5% and the calculator will update instantly. You can also enter a custom VAT rate if needed.
