Yes, all calculators on Rupee Logic are 100% free to use. There are no premium plans, no registration required, and no hidden charges ever.
Our calculators use standard financial formulas approved by RBI, SEBI, and tax regulations. EMI uses the standard reducing balance formula; SIP uses the XIRR-based MF industry standard. Results are for informational purposes and may vary slightly from actual bank/AMC calculations due to rounding.
For most salaried individuals with limited deductions, the New Tax Regime is more beneficial after Budget 2024 changes. However, if you have significant deductions under 80C (₹1.5L), HRA, home loan interest (₹2L), and NPS (₹50K), the Old Regime may save more tax. Use our Income Tax Calculator to compare both regimes instantly.
SIP (Systematic Investment Plan) involves investing a fixed amount every month, which benefits from rupee cost averaging — you buy more units when markets are low. Lumpsum involves investing a large amount at once, which gives full market exposure immediately. SIP is generally recommended for regular income earners; lumpsum suits those with a large investible corpus and long-time horizon.
