Add Pakistan sales tax or remove sales tax from an inclusive invoice amount with quantity, discount and shipping options.
Pakistan sales tax invoice math
Final invoice total
Rs 0.00
Methodology
The calculator applies quantity and discount, treats shipping or service fees as taxable or outside scope according to the selected option, then either adds sales tax to an exclusive base or extracts sales tax from a tax-inclusive amount.
Worked example
If an invoice total already includes 18% sales tax, choose extract mode. The calculator divides the taxable amount by 1.18 to estimate the base and shows the sales tax portion separately.
Common questions
