Frequently asked questions
How is RD maturity calculated?
Maturity M = P × ((1+i)^n − 1)/i × (1+i), where P is the monthly deposit, i = r/12/100 is the monthly rate and n is the number of months.
Why is an RD treated as an annuity due?
The monthly instalment is deposited at the start of each month, so every contribution earns one extra month of interest — that is the (1+i) factor at the end of the formula.
