Free Online Calculators โ Built for India
AWE-OS financial and health calculators are designed specifically for Indian users โ using Indian number formats (โน symbol, lakh and crore notation), Indian regulatory standards (SEBI, RBI, ICMR), and Indian-specific scenarios like SIP investments, PPF accounts, GST calculations, and income tax under both Old and New regimes.
Each calculator runs instantly in your browser with no signup required. The SIP Calculator uses AMFI-standard compound interest formulas and shows returns at 8%, 12%, 15%, and 18% rates with a year-by-year chart. The Income Tax Calculator covers FY 2025-26 slabs for both regimes, the PPF Calculator shows 15-year maturity with withdrawal eligibility, and the FD Calculator compares rates across SBI, HDFC, ICICI, Axis, and Post Office.
For health, the BMI Calculator applies ICMR thresholds (overweight at 23, not 25 as per Western standards) alongside WHO standards โ making it accurate for Indian body types. The Loan EMI Calculator covers home loans, car loans, and personal loans with a complete amortisation schedule showing exactly how much of each EMI goes to principal versus interest.

Frequently Asked Questions
Are these calculators accurate for Indian users?
Yes. All financial calculators use Indian standards โ โน rupee format, lakh and crore notation, SEBI-specified SIP formulas, RBI PPF rate (7.1%), and FY 2025-26 income tax slabs for both Old and New regimes. The BMI Calculator applies ICMR thresholds (overweight at BMI 23) rather than the Western WHO standard of 25.
Do the calculators store my financial data?
