VAT Calculator

A VAT calculator works out Value Added Tax on a price - either adding VAT to a net amount or removing VAT from a gross amount to find the original price. It defaults to Nigeria's 7.5% standard rate but accepts any percentage, so it works for the UK (20%), South Africa (15%), the EU, and anywhere else.

Add VAT vs remove VAT

• Add VAT - you have a price before tax and want the final amount a customer pays. The calculator shows the net, the VAT, and the gross total.
• Remove VAT - you have a VAT-inclusive total (say, off a receipt) and want to know the tax portion and the original net price.

How VAT is calculated

To add VAT, multiply the net amount by the rate: at 7.5%, ₦10,000 × 0.075 = ₦750 VAT, giving a gross of ₦10,750. To remove VAT, divide the gross by (1 + rate): ₦10,750 ÷ 1.075 = ₦10,000 net, so the VAT was ₦750. Removing VAT is not the same as subtracting 7.5% from the gross - a common mistake this calculator avoids.

Who needs this

• Small businesses pricing goods and issuing VAT invoices.
• Freelancers and vendors quoting clients tax-inclusive or tax-exclusive prices.
