Methodology
Formulas and sources
Every calculator implements the official Indian formula for its instrument:
- Loans: RBI reducing-balance,
EMI = P × R × (1+R)ⁿ / ((1+R)ⁿ − 1)per RBI Master Circular on Loans and Advances. - Tax: Income Tax Act, 1961 — section-by-section citation on each calculator (24(b), 80C, 80D, 80E, 10(13A), 24, 80EEA, etc.).
- Mutual funds / SIP: compound growth with monthly compounding, per SEBI illustration norms.
- Pension (EPF/EPS/NPS/Gratuity): EPFO Act / Payment of Gratuity Act 1972 / PFRDA NPS architecture.
- FD/RD: compound interest at quarterly compounding (or as specified by bank disclosure).
