How to use the Sales Tax Add/Remove Calculator Pakistan

Pakistani shopkeepers constantly need both directions of sales tax math: adding 18% GST to a tax-exclusive quote, and stripping it out of a tax-inclusive market price. This sales tax add remove calculator for Pakistan at 18 percent shows all three figures at once — price with tax added, tax-exclusive price, and the tax hidden inside — so invoices and quotations are always correct.

  1. Enter the amount — either your tax-exclusive cost or the tax-inclusive market price.
  2. Confirm the tax rate (18% is Pakistan's standard; change it if your sector differs).
  3. Click Calculate and read the line you need: with-tax-added for quoting, tax-removed for stripping.
  4. Use the tax-inside figure when separating GST on purchase invoices for your records.

Formula

With tax added = Amount × (1 + Rate ÷ 100). Tax-exclusive = Amount ÷ (1 + Rate ÷ 100). Tax inside = Amount − Tax-exclusive. Removing tax is division, not subtraction of 18% — a common error.

Worked example

On Rs 10,000 at 18%: with tax added = 10,000 × 1.18 = Rs 11,800. Stripping tax from Rs 11,800: 11,800 ÷ 1.18 = Rs 10,000 exactly, with Rs 1,800 tax inside. Simply subtracting 18% would wrongly give Rs 9,676.

Frequently asked questions

18% is the standard rate, but many items have reduced, zero, or exempt rates under various SROs, and services are taxed by provinces. Verify your sector's current rate before invoicing.

Because the 18% was calculated on the smaller exclusive price. On Rs 11,800, the tax is 1,800 ÷ 11,800 = 15.25% of the inclusive price. Always divide by 1.18 to strip it correctly.

Only FBR-registered persons charge sales tax, generally required above turnover thresholds. Unregistered small retailers usually sell tax-inclusive without separating GST — consult a tax advisor.
