RD vs SIP for a first-time investor

Both drip money every month—risk is the split

A recurring deposit takes a fixed instalment each month and pays a bank rate known at booking (subject to the bank's terms). Maturity is largely predictable if you complete the tenure. A SIP buys mutual-fund units every month at that day's NAV. The instalment is fixed; the final corpus is not. Over long equity horizons the SIP path often ends higher in historical averages, and it can also finish lower after a bad stretch.

If the money is for a gadget, a wedding deposit, or fees inside one to three years, an RD (or a short FD ladder) matches the need better than equity SIP maths.

First job, small surplus: keep one clear goal

Build a small emergency float in a savings account or liquid parking first. Then pick one goal date. Use the RD calculator with the bank rate on offer for short goals. Use the SIP calculator with a conservative expected return—not a brochure peak—for goals five or more years out. Do not run a 12% SIP projection against a three-year school-fee deadline and call it a plan.

You can hold both: an RD for the near fee and a small SIP for a longer corpus. The mistake is treating them as interchangeable just because both debit monthly.

What the calculators leave out

RD interest is taxable; SIP equity gains have their own capital-gains rules when you redeem. Exit loads, expense ratios and your own pause months also sit outside a simple projection. Use the two tools to size the instalment, then read the product documents before you start.
