It uses the standard reducing-balance formula used by Indian banks. Enter your principal, rate, and tenure for exact monthly instalment, total interest, and an amortisation schedule.
SIP wins for most people because it removes market-timing risk through rupee-cost averaging. Lumpsum can win if you invest at market lows. The simulator shows the exact difference for your amount and tenure.
It depends on your city, price-to-rent ratio, and investment returns. The Rent vs Buy Simulator models appreciation, rental yield, and opportunity cost — in most Tier-1 cities, the break-even is 12–18 years.
The new regime wins if your total deductions (80C + HRA + NPS + others) are below ~₹3.5L. Above that, the old regime often saves more. Run the Old vs New Tax Simulator with your actual numbers — it updates instantly.
Target 6 months of essential expenses (rent, EMIs, groceries, utilities). The Emergency Fund Calculator tells you exactly how many months your current savings cover and how much more you need. Track it in the Wealth Wallet.
