🧮 Calculators

Accurate free calculators for health, finance, and education. All calculations happen in your browser — instant, private, and free.

AWE-OS financial and health calculators are designed specifically for Indian users — using Indian number formats (₹ 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 — 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.
