About Us

Free Online Calculators Pakistan | Tax, Bills & CGPA is a free collection of calculators built for everyday questions in Pakistan: electricity bills, salary tax, zakat and inheritance, PTA tax, admission aggregates, CGPA, loans, construction and dates. Every calculator runs in your browser; nothing you type is stored.

How the calculators are built

Each calculator uses a published formula or an official rule, and the page shows that formula, a worked example with real numbers and the limits of the estimate. Where a calculator depends on rates set by an authority (NEPRA tariffs, FBR tax slabs, PTA duty, the zakat nisab), the page names the source and the date the figures were last checked.

Verified and reported figures

A figure marked verified has been checked against the authority’s own document. A figure marked reported comes from news or secondary sources while the official document is not yet available; treat it as a guide and confirm it before you pay, file or apply.

Updates and corrections

Rates are reviewed after each budget, tariff decision or notification. If you find a wrong figure, please tell us through the contact page with the official source, and we will correct the page and note the date of the change.

Not professional advice

Results are estimates for planning. For tax returns, bank finance, inheritance or religious rulings, confirm with FBR, your bank, a lawyer or a qualified scholar.
