Which calculator do I need?
- Salary income tax — monthly and annual FBR tax on your salary for FY 2026-27, with a slab-by-slab breakdown and take-home pay.
- Salary tax table — look up the monthly tax and take-home pay for common salaries from Rs 50,000 to Rs 10 lakh without typing anything.
- Zakat calculator — 2.5% Zakat using today's gold or silver nisab in PKR.
- MDCAT aggregate and university merit — MBBS/BDS, UET, NUST, PU, BS and MPhil aggregates from your marks.
- GPA & CGPA — semester and cumulative GPA on the HEC 4.0 scale.
- Solar net-billing — savings, system size and payback under NEPRA's 2026 rules.
Why freshness matters
Pakistan's tax slabs change with every federal budget, admission formulas change with each prospectus, and NEPRA revises solar buyback rules. A calculator that was right last year can quietly give you the wrong number this year. Every tool here shows the date its figures were last checked and links to the source.
