How to Use This Free Online GST & VAT Calculator
Our intelligent financial tool allows business owners, freelancers, and accountants to instantly determine tax calculations without the hassle of manual math. Whether you are generating an invoice or auditing purchases, this tool guarantees precise values across multiple global currencies.
Adding Tax to a Base Price
Select the "Add GST/VAT" option when you have a net amount and need to calculate the final price an end-user will pay. The algorithm automatically determines the exact tax volume based on your selected percentage and sums it into the Gross Total.
Reverse Calculating (Removing Tax)
If you have a receipt with a final total and need to extract the exact base price and the tax paid, select the "Remove GST/VAT" tab. This reverse-calculation method is highly useful for corporate expense claims, ensuring accurate tax credit inputs.
17 Currencies & Automatic CGST/SGST Split
The calculator supports 17 major currencies — from USD, PKR, and INR to AUD, SGD, and ZAR — so freelancers and businesses billing international clients don't need to convert figures manually. For applicable tax regimes, the tool also shows the CGST/SGST split, giving accountants a ready breakdown for compliance filings.
Free GST & VAT Calculator for Invoices and Pricing
Adding or removing tax by hand is where most pricing mistakes happen — a misplaced decimal on a client invoice can cost you real money. The sedoc Tax Calculator handles both directions of the math instantly, so you can quote, invoice, and reconcile without opening a spreadsheet.
1. Add Tax or Reverse-Calculate It
Enter a base price to add GST/VAT on top, or enter a tax-inclusive price to work backward and see the original amount plus the tax portion separately. Both directions matter: quoting a client needs the first, checking a supplier's invoice needs the second.
2. Any Tax Rate, Any Currency
Set a custom tax percentage instead of being locked to one country's rate, and switch currencies so the output matches the invoice you're actually preparing — useful if you bill clients in more than one region.
3. Numbers You Can Trust on an Invoice
The calculation runs locally in your browser the moment you type, with no rounding surprises and no server round-trip, so the figure you copy into an invoice or quotation is the one you can rely on.
