RD Calculator
Maturity value of a monthly recurring deposit with quarterly compounding, as banks compute it.
Inputs
Formula
- i = r / 400 (quarterly rate as banks apply it)
- Each instalment compounds for the remaining quarters:
- M = Σ A × (1 + i)^((n − k + 1)/3)
- Interest = M − (A × n)
Banks credit RD interest quarterly, but instalments arrive monthly, so each deposit compounds for a fractional number of quarters equal to its remaining months divided by three. Summing across all instalments gives the maturity value — the same result the RBI-prescribed RD formula produces.

Assumptions
- Instalments are paid on time; missed instalments attract a penalty and reduce maturity.
- Quarterly compounding, the standard for scheduled commercial banks.
- TDS is not deducted from the displayed maturity value.
Tips
- An RD suits goal-based saving under 5 years where capital safety matters more than return.
- For 5+ year goals, compare against a debt fund SIP on a post-tax basis.
Warnings
- Interest is fully taxable at slab; RDs rarely beat inflation post-tax for 30% slab investors.
