Why qaaf
qaaf is a free calculator site for Pakistan. It answers the numbers people look up every month: tax on a salary, an electricity or gas bill, a university CGPA, an admission aggregate, a plot size in marla or the zakat on savings.
Every calculator names the rule it follows. That could be the Finance Act slab table, a NEPRA tariff decision, a university's grading table or a PMDC admission rule. Each result shows its working step by step, so you can check it against your own bill or result card.
We test each tool against real examples before it goes live. Our electricity calculator matches a real LESCO bill to within a rupee, and the tax slabs are checked at every boundary. Rates are updated when new ones are notified. Read more on how we check the numbers.
qaaf is independent and not linked to any government body or university. Your inputs stay in your browser.
