How Retail Discount & Sales Tax Calculation Works in Pakistan

Calculating the true checkout cost during promotional sales in Pakistan requires understanding two distinct arithmetic steps: subtracting the promotional discount percentage from the tag price and adding the applicable Federal Board of Revenue (FBR) General Sales Tax (GST) or provincial sales tax.

1. Step-by-Step Mathematical Formula

When shopping at top fashion brands (like Khaadi, Sapphire, or Gul Ahmed) or major e-commerce platforms (like Daraz 11.11 / 12.12 sales), calculations follow a standard two-phase structure:

• Discount Savings: Savings = Tag Price × (Discount % ÷ 100)
• Sale Price (Pre-Tax): Sale Price = Tag Price - Savings
• FBR GST 18% Amount: GST = Sale Price × (GST % ÷ 100)
• Final Payable Price: Total = Sale Price + GST

2. FBR Sales Tax Treatment on Discounted Items

Under the Pakistan Sales Tax Act 1990 and current FBR regulations, sales tax is assessed on the actual value of supply. This means that when a shop or online store offers a genuine commercial discount, the 18% GST is calculated on the reduced sale price rather than the original pre-discount sticker price. For example, a PKR 10,000 apparel suit discounted by 30% yields a pre-tax sale price of PKR 7,000. The 18% GST (PKR 1,260) is charged on PKR 7,000, bringing the final checkout total to PKR 8,260.

3. Goods vs. Services Tax Regimes in Pakistan

While standard manufactured goods (clothing, electronics, cosmetics, appliances) carry the 18% federal GST rate, services such as restaurant dining, hotel bookings, or beauty salons fall under provincial revenue jurisdiction (PRA in Punjab, SRB in Sindh, KPRA in KP). Provincial sales taxes on services typically range between 13% and 15%. This calculator allows you to customize the tax percentage so you can compute exact billing for any category across Pakistan.
