Calculate the net price excluding VAT, or add VAT to get the gross price.
Add VAT: amount × (1 + VAT%). Remove VAT: amount / (1 + VAT%).
Standard VAT rates: UK 20%, EU 19-21%, Australia 10%.
This calculator earns its keep at decision points: before accepting a loan, comparing investment platforms, or negotiating salary. The difference between the headline figure and the true cost or return is only visible with accurate arithmetic.
The most consequential mistake is comparing financial figures that are not on the same basis — gross versus net, before-tax versus after-tax, or nominal versus inflation-adjusted. Always check whether figures you are comparing use the same definition.
A first-time buyer models three scenarios before making an offer: 10%, 15%, and 20% deposit on a £280,000 property. The calculator shows exactly how the monthly payment and total interest cost change with each deposit level, making the decision visible rather than speculative.
Divide the gross price by 1.20 to get the net price.
