How RupeeCalc explains calculations
EMI Calculator uses the standard reducing balance method — the standard amortisation formula commonly used for reducing-balance loans. Income Tax Calculator covers the Income Tax Department guidance with marginal-relief notes for FY 2025-26 / AY 2026-27, visible HRA assumptions, and verified tax examples. The page shows assumptions clearly so users can verify them. GST Calculator correctly handles reverse GST — the formula is easy to confuse. Gratuity Calculator uses the correct divisor: ÷26 for Payment of Gratuity Act covered employees, ÷30 for non-covered. SIP Calculator uses the correct compounded monthly return formula with step-up SIP support. Compound Interest Calculator lets you choose compounding frequency, which affects FD results by thousands of rupees.
