Guides & Resources

What you'll find here

The LaliAI blog exists for one reason: a number on its own rarely tells you what to do next. Each guide walks through the formula behind a calculator, shows a worked example with real figures, flags the mistakes people make most often, and links straight to the tool so you can run your own numbers in seconds.

Browse by category

• Finance — mortgages and amortisation, income tax slabs, zakat and nisab, loan EMI, compound interest, savings goals, retirement and net worth.
• Health — BMI and its limits, TDEE and macros, body fat methods, ideal weight formulas, water intake and pregnancy dates.
• Math — percentages, number bases, scientific notation, ratios, averages and the shortcuts worth memorising.
• Lifestyle & Education — fuel costs, electricity bills, tipping, CGPA and percentage conversions, and study-planning maths.

Written to be used, not skimmed

Every article is written by a practitioner, updated when rates and rules change, and kept free of gated downloads and signup walls. Currency examples default to USD, but the calculators themselves adapt to the country and currency you select, so figures stay meaningful whether you are in Karachi, London or Toronto.
