VAT is rounded to the nearest penny; net and VAT always add up to the gross.

What it does

Add VAT to a price or take it out of a total, at any rate. You see the net amount, the VAT and the gross amount to the penny, and the three always add up exactly.

  1. 01

    Add or remove VAT

    Start from a price before VAT, or from a total that already includes it.

  2. 02

    Any rate

    The UK's 20%, 5% and 0% rates are one tap away, and any other rate works too.

  3. 03

    Exact to the penny

    VAT is rounded to the nearest penny and the net and VAT always add up to the gross.

  4. 04

    Copy the working

    One click copies the sum, ready for a quote, an invoice or an email.

How to use it

  1. 1

    Choose add or remove

    Add VAT to a net price, or remove it from a total you've been charged or quoted.

  2. 2

    Pick the rate

    Use the standard rate unless the goods or services qualify for a reduced or zero rate.

  3. 3

    Use the figures

    Copy them into your invoice, or keep your invoices in Zelvorm Books, which does the sums for you.

Reading your results

Good

Figures that add up

Net plus VAT equals gross to the penny, which is what your invoice and your VAT return need.

Check

Check the rate

Some goods and services use reduced or zero rates. If you're not sure, check HMRC's guidance or ask your accountant.

Fix

Not VAT registered

If your business isn't VAT registered, you mustn't charge VAT or show it on invoices.

Why it matters

A VAT figure that's a penny out on an invoice, or a total that doesn't match the quote, makes clients query bills and makes your VAT return harder to reconcile. Doing the sum the same way every time, to the penny, avoids both.

Questions

About the VAT calculator.

Divide the total by 1 plus the rate. At 20%, divide by 1.2 to get the net amount; the VAT is the difference. This calculator does that when you choose Remove VAT.
