How Learntrix Calculators Work: Precision Engineering & Client Privacy
Every calculator in our directory is built upon verified actuarial standards, peer-reviewed clinical equations, and official government statutory schedules.
Personal Finance & Tax Rules
Our financial engines adhere strictly to banking standards. Loan EMI and mortgage computations utilize standard reducing-balance actuarial amortization models. Tax modules are calibrated to current official statutes—including Section 115BAC New Tax Regime slabs (FY 2025-26 & AY 2026-27), CBIC GST bifurcations (CGST/SGST/IGST), and sovereign National Savings Institute rules for Public Provident Fund (PPF) quarterly compounding.
Health & Anthropometrics
Metabolic and body mass tools implement international clinical consensus guidelines established by the World Health Organization (WHO), the Mifflin-St Jeor Total Daily Energy Expenditure (TDEE) equation, and the Devine/Robinson ideal body weight formulations. Asian-specific BMI thresholds (23.0 cutoff) are surfaced alongside global standards to deliver medically sound context.
100% In-Browser Privacy
Unlike cloud-hosted fintech apps that require user account creation and transmit financial data to remote servers, every calculation on Learntrix executes entirely inside your browser memory sandbox. Your salaries, loan balances, tax deductions, and health metrics are never transmitted over network sockets or stored in server logs.
