How this works
Recurring Deposit maturity compounds each month's fixed contribution the same way a SIP does — the tenure here is entered in months rather than years, since RD terms are commonly quoted that way (like 18 or 30 months) and don't always land on a whole year.
Common questions
Why does it ask for months instead of years?
RD tenures are often not whole years — 15, 18, 33 months are common — so months avoids forcing an inexact conversion the way a years-only field would.
Is RD interest compounded the same way as FD?
Both compound, typically quarterly at most banks, but RD adds a new contribution every month on top of the growing balance, while FD is a single lump sum growing on its own — different cash-flow pattern, same underlying compounding idea.
