BachatGuru is a calculator for estimation and education only. It is not a lender and does not provide loans, investments, payments, financial advice, or account access — every result is computed locally on your device from values you enter.
LOANS
• EMI calculator with presets for home, car, personal, gold, education & two-wheeler loans
• Full amortization schedule with year-wise principal/interest breakup
• Prepayment planner — see months and interest saved by a lump-sum or extra monthly payment
• True Rate Checker — converts a "flat rate" quote to the real reducing-balance rate, and computes the all-in APR including processing fees, the same way RBI's Key Facts Statement requires banks to disclose it
SAVINGS
• FD calculator with quarterly compounding (the actual Indian bank convention) and senior-citizen rates
• RD and PPF calculators — PPF models the real rule: interest on the lowest balance between the 5th and month-end, so you can see why depositing before the 5th earns more
INVESTING
• SIP calculator with annual step-up and goal-seek ("what monthly SIP reaches ₹1 crore?")
• Inflation-adjusted "in today's money" values
• Lumpsum and CAGR calculators
EVERYDAY
• GST calculator with the current slabs (5%, 18%, 40% de-merit, 3% gold) and CGST/SGST/IGST split
