  • Tool C – Increase / Decrease: Find the percentage change between two values. Example: Price went from Rs 500 to Rs 650 — that's a 30% increase.

❓ Frequently Asked Questions

Answers to common questions

Where is my BMI data saved? ▼
Nowhere. This tool is 100% front-end. Your height, weight, and age are only processed in your browser and never sent to any server. Refreshing the page resets everything.
Does the tax calculator use official tax rates? ▼
No. This calculator uses the custom tax rate you enter yourself. For accurate FBR tax slabs, you should consult the FBR website or a Chartered Accountant. This is an estimation tool only.
How does the Loan EMI calculation work? ▼
We use the standard EMI formula: EMI = P × r × (1+r)^n / ((1+r)^n – 1), where P = principal, r = periodic interest rate, and n = total periods. This is a globally accepted formula used by banks.
Can I calculate both discounts and student marks in the percentage tool? ▼
Yes! The percentage section has three separate tools: Tool A for discounts, Tool B for marks/comparison, and Tool C for increase/decrease. Each has its own Calculate button.
Does this work on mobile phones? ▼
Absolutely! The entire website is built with a mobile-first responsive design. All calculators, the BMI meter, and charts display perfectly on any screen size.
What is the healthy BMI range for adults? ▼
According to WHO: Below 18.5 = Underweight, 18.5–24.9 = Normal (healthy), 25–29.9 = Overweight, 30 or above = Obese. For children, different percentile charts apply based on age and gender.
