Choose Add GST to find the tax and gross price from a net amount, or Remove GST to extract the tax from a GST-inclusive price. The calculator shows the GST amount and splits it equally into CGST and SGST for intra-state sales.
What does this tool do?
Adds or removes Pakistan’s General Sales Tax from any amount. Enter a pre-tax price to get the GST-inclusive total, or a billed total to extract the GST component — with the standard 18% rate pre-filled and adjustable.
Because the math runs locally, the GST Calculator works offline after the page loads and never queues behind a server — handy during load-shedding or on slow mobile data. There is nothing to install and no account to create; the page is the whole application, ready in the time it takes to open a tab.
The interface keeps things practical: the inputs are “Amount”, “GST rate (%)” and “Currency symbol (optional)”; “Add GST” runs the tool; “Remove GST” runs the tool. Results update live as you work — there is no waiting and nothing to submit.
How do I use this tool?
Enter your figures below — every result updates the instant you type, so comparing scenarios is just a matter of changing a number and watching the answer move.
- Enter your values in “Amount”, “GST rate (%)”, “Currency symbol (optional)”.
- Click “Add GST” to run the tool and see the result.
How does it work?
GST-inclusive = base × (1 + rate/100); GST extracted = total − total/(1 + rate/100). Pakistan’s standard GST rate is 18% (2026), with reduced rates on some services and items varying by province — adjust the rate field to match your case.
Precision is full floating-point throughout; only the displayed result is rounded for readability. Intermediate steps are not rounded, which avoids the small compounding errors you get from rounding mid-calculation on a phone calculator.
Use cases in Pakistan
Every Pakistani receipt carries GST: restaurants, retailers, telecom top-ups and professional services. Freelancers and shopkeepers use this to quote GST-inclusive prices, extract the tax component for record-keeping, and check that a bill’s tax line is honest. Remember FBR-registered businesses must show GST separately on invoices.
Families use it for household budgeting and school-fee planning; small businesses for pricing and payroll math; students for everything from BISE numericals to CSS preparation. Wherever the same calculation is repeated monthly — bills, salaries, savings targets — this page replaces the phone-calculator ritual.
Limitations
Rates differ by sector and province (services GST is provincial and varies), and some items are exempt or zero-rated — 18% is the standard goods rate, not universal. This is an arithmetic helper, not tax advice; for filings and registration questions consult FBR guidance or a tax professional.
Assumptions are stated on the page — read them before trusting the headline number for money, health or legal decisions. A calculator amplifies the quality of its inputs: careful numbers in, trustworthy numbers out.
Frequently asked questions
What is Pakistan’s GST rate?
18% is the standard federal rate on goods (2026). Services are taxed by provinces at varying rates, and some items are exempt or zero-rated. For figures that go into applications or documents, double-check the inputs against the source — the math is exact, but only for the numbers you enter.
How do I remove GST from a billed total?
Divide by 1.18 (at 18%): a Rs 1,180 bill holds Rs 180 GST and a Rs 1,000 base. Use the “extract” mode above. Try varying one input at a time to see which assumption drives the result; that sensitivity check is often more valuable than the headline number.
Is GST the same as VAT?
Conceptually yes — both are value-added taxes. Pakistan calls its version GST; the mechanics match. Save or screenshot the result with its inputs when the figure matters later — reconstructing “what did I enter?” is harder than it sounds.
Do I need to register for GST?
Businesses above the turnover threshold must register with FBR. This calculator only does the arithmetic — registration rules are separate. For figures that go into applications or documents, double-check the inputs against the source — the math is exact, but only for the numbers you enter.
Is my data uploaded or stored?
No. This tool runs entirely in your browser — what you type or paste never leaves your device, is never sent to a server, and is never stored. Closing the tab removes all trace. Try varying one input at a time to see which assumption drives the result; that sensitivity check is often more valuable than the headline number.
Is it really free? Do I need an account?
Yes, free, and no account needed. Open the page and use it — no sign-up, no trial, no watermark on results. Save or screenshot the result with its inputs when the figure matters later — reconstructing “what did I enter?” is harder than it sounds.
