Free Online Calculators: EMI, GST, SIP, Age, BMI and Percentage
Work out percentages, age, BMI, loan payments and investment estimates. Results update as you type, and each page explains its formula. Regional features, including India's GST and rupee-based examples, are labeled on the relevant tools.
Understand each calculator's scope
Percentage, age and other everyday calculations can be used wherever you are. The loan and investment tools currently display Indian rupees with lakh/crore grouping. The GST tool uses India's CGST, SGST and IGST structure, rather than the tax rules of every country. Check the labels and examples before using a regional result.
Check the maths yourself
A calculator is only useful if you can trust it, so every calculator page writes out its formula and works through an example with real numbers. If your bank quotes a different EMI, the difference usually comes from processing fees, insurance bundled into the loan, or a slightly different interest rate, and the page explains how to spot which.
Estimates, not advice
These tools give you clear numbers to plan with, but they can't see your full situation. Before taking a loan or investing, confirm figures with your lender, fund house or a qualified adviser. BMI is a screening number for adults, not a diagnosis.
