The decision points around household loans and investments are almost always about the schedule — what does the interest-principal split look like in month 24, what is the outstanding balance just before a planned prepayment, and how much of my recurring SIP contribution becomes wealth gain versus invested capital over ten years.

The calculators here are built to answer those questions in full detail. The EMI Calculator produces a month-wise amortisation table with conditional formatting, making it easy to time a partial prepayment. The FD & RD Calculator applies the correct compounding frequency (quarterly for FD, monthly for RD) and reports both pre-tax and indicative post-tax yield. The SIP Calculator covers both constant and step-up SIPs, with the wealth gain curve shown alongside invested amount — useful for illustrating the compounding effect to first-time investors.
