Frequently asked questions
How do I add sales tax to a price?
Choose “Add tax”, enter the net price and the tax rate, and the calculator multiplies the price by the rate and adds it on top. For example, $100 at 7.25% gives $7.25 tax and a $107.25 total.
How do I remove VAT or GST from a total?
Choose “Remove tax” and enter the tax-inclusive amount. The calculator divides by (1 + rate) to find the net price, then shows the tax portion. For example, £120 incl. 20% VAT is £100 net and £20 VAT.
What tax rates do the region presets use?
The presets load a common headline rate (e.g. UK VAT 20%, Australia GST 10%, India GST 18%) as a starting point. Tax rates vary by product, state and province, so always confirm the correct rate for your situation and override it if needed.
Does SnapBilly handle tax on invoices automatically?
Yes. SnapBilly lets you set tax rates per invoice or item — including GST with CGST/SGST/IGST for India — and totals everything for you, so you don’t calculate tax by hand.
