Recurring deposit with quarterly compounding.
Recurring deposits here use monthly contributions and the rate you type, compounded quarterly in the usual bank approximation. Match the bank circular if you need the rupee on the certificate.
Worked example: ₹2,000 a month for 3 years at 7%. Invested is ₹72,000. Maturity is a little above that. The extra is interest under this approximation.
Missed instalments and penalties are bank-specific. This page does not fine you.
