About PakCalculators.com
PakCalculators.com is built for students, job seekers and families in Pakistan. I am Habiba, founder of this site from Punjab, Pakistan. I created these tools because many online calculators do not follow Pakistani rules, and I wanted to make simple tools that anyone can use on their phone.
What you will find here
I have 14 free tools. For students, there is the BISE Percentage Calculator which uses the common grading bands, GPA and CGPA calculators for the 4.0 scale used by most Pakistani universities, GPA calculators for UK and USA scales for those applying abroad, a Merit Calculator where you can enter your own weightages, and an Age Calculator for jobs and admissions.
For families, I have an Islamic Inheritance Calculator that estimates shares using simplified Hanafi rules. This is for information only and is not a fatwa, so please confirm with a local scholar for your final case. I also have an AC, Fan and UPS Electricity Cost Calculator to estimate your monthly bill, and a Loan EMI Calculator that uses the standard reducing-balance formula.
For jobs and office work, I have a Gratuity Calculator and a Pension Calculator. The pension tool is based on average emoluments as mentioned in recent Finance Division circulars. Since provincial rules can differ, please check with your accounts office. All calculations run in your browser, so your numbers stay on your device and are not sent to any server.
How to use these calculators
Each calculator page explains the formula first and then asks for numbers. For example, the percentage tool asks for obtained and total marks from your BISE result card. The merit tool asks for your matric, inter and entry test percentages. The BMI tool asks for weight in kg and height in cm. Just enter your numbers and press the button like Calculate Percentage or Calculate Merit to see the result.
I try to keep every formula in line with published rules. Where rules differ between boards or universities, I mention that on the same page. If you find any error or want a new calculator, please contact me directly through the Contact Us page. I read every message myself and usually reply within 2 to 3 working days.
