GST (Goods and Services Tax) is a multi-stage, destination-based consumption tax levied at every value addition. It is used in India, Pakistan, Australia, Canada, Singapore, New Zealand and many other countries, and replaces the patchwork of older indirect taxes. In Europe and the UK, an equivalent tax is called VAT (Value Added Tax). In the US, a similar concept is called Sales Tax, though it is applied differently (single-stage, at point of sale).

How do I add GST to a price?

To add GST, multiply the original price by the GST rate and divide by 100, then add the result to the original price. Formula: Total = Original Price + (Original Price × GST% / 100). Example: $1,000 base + 18% GST = $1,000 + $180 = $1,180 total.

How do I remove GST from an inclusive price?

Removing tax is trickier than adding it because you cannot just subtract the percentage. You must divide the total price by (1 + tax rate). Formula: Base Price = Total Price ÷ (1 + GST% / 100). Example: $1,180 inclusive ÷ 1.18 = $1,000 base, with $180 as the GST. Our Remove Tax mode does this back-calculation automatically.

What is the difference between inclusive and exclusive tax?

Tax-exclusive (Add Tax) means the tax sits on top of the net price, common on B2B invoices and US sales tax shown at checkout. Tax-inclusive (Remove Tax) means the tax is already baked into the displayed total, common on retail price tags in countries with VAT/GST. Picking the wrong mode is one of the most common accounting errors, so always check whether the figure you have is net or gross before choosing.

What GST or VAT rates apply in different countries?

Rates vary widely. Common examples: UAE VAT 5%, Singapore GST 9%, Australia GST 10%, Indian GST 5/12/18/28% slabs, Pakistan GST 17-18%, UK VAT 20%, EU VAT typically 19-25%, Canada GST 5% federal plus provincial sales tax. Rates change over time, so always verify the current rate from your local tax authority before filing.

Is this calculator official or legally binding?

No. The tool uses standard mathematical formulas that match how tax authorities calculate GST/VAT, but it is meant for estimation, invoicing assistance and quick decisions. For official filings, consult a certified accountant or your country's tax portal to confirm the correct slab, exemptions and reverse-charge rules.

Can I use it for compound or layered taxes?

The calculator is built for a single percentage applied to a base value. For layered taxes like Indian CGST + SGST or Canadian GST + PST, calculate each component separately by running the tool twice (once per rate) and adding the tax amounts. For complex compound situations, an accountant is the safer route.

How to calculate 18 percent GST on a calculator?

To add 18% GST to a base price: multiply the base by 1.18. For example, PKR 1,000 × 1.18 = PKR 1,180 total (PKR 180 is the tax portion). To remove 18% GST from an inclusive price: divide the total by 1.18. For example, PKR 1,180 / 1.18 = PKR 1,000 base. Our calculator handles both directions automatically, pick Add Tax mode or Remove Tax mode and enter your figure.

How to calculate GST in Pakistan?

Pakistan's standard sales tax (administered by Federal Board of Revenue) is 18 percent on most goods (raised from 17 percent in the 2024 finance act). Different categories have different rates: petroleum products around 17 percent, restaurants around 16 percent, textile around 15 percent, plus optional 5 percent Federal Excise Duty for B2B. Always verify the current applicable rate from [FBR](https://www.fbr.gov.pk/) for federal sales tax, or from SRB (Sindh), PRA (Punjab), KPRA (KP), BRA (Balochistan) for provincial sales tax on services. Pick the appropriate rate in our calculator.

What is the GST on PKR 20,000 at 18 percent?

GST on PKR 20,000 at 18% is PKR 3,600 (20,000 × 0.18). Total inclusive price is PKR 23,600. Conversely, if PKR 20,000 is already a GST-inclusive total at 18%, the base price is PKR 20,000 / 1.18 = PKR 16,949 and the GST portion is PKR 3,051. Always confirm whether the figure quoted to you is exclusive (add tax) or inclusive (remove tax) before invoicing.

How do I calculate 15 percent GST?

To add 15% GST: multiply base by 1.15. To remove 15% GST from an inclusive total: divide total by 1.15. Example for adding: PKR 1,000 × 1.15 = PKR 1,150. Example for removing: PKR 1,150 / 1.15 = PKR 1,000 base, with PKR 150 as the GST portion. Pakistan applies 15% to certain categories (textile, some services); Saudi Arabia uses 15% as its standard VAT rate. Set the rate to 15 in our calculator and pick Add or Remove Tax mode.

About the Pakistan GST Calculator (17% / 18%)

The Toolsfluent Pakistan GST Calculator handles the actual rates Pakistani businesses and shoppers deal with: 18 percent standard GST (current Federal Board of Revenue rate, raised from 17 percent in the 2024 budget), 17 percent on petroleum products, 16 percent on restaurant services, 15 percent on textile, plus optional 5 percent Federal Excise Duty for B2B invoicing.
