Quick Work StudioCalculators
Add tax to a price.
The Sales Tax / GST Calculator is a free online tool in Quick Work Studio's calculators collection. Add tax to a price. The tax amount is the price multiplied by the tax rate; adding that to the price gives the total you'd pay at checkout.
This kind of calculation is common enough that most people do it in their head or on a napkin at some point — which is exactly where small arithmetic mistakes creep in. Using a dedicated calculator removes that risk and gives you the number instantly.
Like every tool on Quick Work Studio, the Sales Tax / GST Calculator is 100% free, requires no sign-up, and works instantly in any modern browser on desktop or mobile — it's one of 100+ tools built to save you a small chunk of time without getting in your way.

The calculation method is the same (price × rate), though VAT/GST systems in some countries apply tax differently across the supply chain rather than just at final sale.
