Investment Planning Tools
The investment calculators on this page cover the full spectrum of personal finance decisions. The SIP Calculator uses the Future Value of Annuity formula to project mutual fund returns over any duration. The FD Calculator supports monthly, quarterly, half-yearly and annual compounding so you can compare Fixed Deposit offers from different banks. The PPF Calculator works at the current government rate of 7.1% p.a. and shows the full 15-year EEE tax-free maturity breakdown.
Loan & Tax Calculators
The EMI Calculator covers home loans, car loans, personal loans and education loans — it generates a full year-by-year amortization schedule so you can see exactly how much of each payment goes towards principal versus interest. The GST Calculator handles both add-GST and remove-GST modes across all four GST slabs (5%, 12%, 18%, 28%) and shows the CGST, SGST and IGST split.
Why These Calculators Are Accurate
