Work out VAT yourself on your phone (25%)

Diagram: VAT from net to gross, net × 1.25 = gross
Net × 1.25 = gross (25% VAT). Reverse: gross ÷ 1.25 = net.

With just your phone’s calculator, three taps are enough. The examples use 25% VAT – the most common rate for construction services.

  • Add VAT: price excl. VAT × 1.25 = price incl. VAT.
    E.g. 10,000 × 1.25 = 12,500 kr.
  • Remove VAT (reverse): price incl. VAT × 0.8 = price excl. VAT.
    E.g. 12,500 × 0.8 = 10,000 kr. (Dividing by 1.25 gives the same answer.)
  • Just the VAT: price incl. VAT × 0.2 = the VAT.
    E.g. 12,500 × 0.2 = 2,500 kr.

The shortcuts × 0.8 and × 0.2 apply to 25% only. At 12% divide by 1.12 to remove the VAT, and at 6% by 1.06.

Reverse-charge VAT in construction

Between construction companies, reverse charge (omvänd byggmoms) often applies: the seller invoices without VAT and the buyer accounts for it. The calculator still helps you see the VAT amount involved.

Frequently asked questions about VAT

How do I work out VAT on an amount?
If the amount is excluding VAT, multiply by the rate (e.g. 0.25 for 25%). If it is including VAT, divide by 1.25 to get the amount excluding VAT – the calculator does both automatically.
Which VAT rate applies to construction services?
25% on virtually all construction and trade work. The rate follows the service, not who is invoicing – and between construction companies reverse charge can shift the VAT reporting to the buyer.
How do I reverse-calculate from a price including VAT?
Switch the calculator to "Including VAT" and enter the gross price. It then breaks out both the amount excluding VAT and the VAT itself for you – no manual maths needed.
Does it cost anything?
No, the calculator is free and requires no account.
