Frequently asked questions

How is RD maturity calculated?
Indian banks use the formula M = R × [(1+i)^n − 1] / i × (1+i), where R is monthly deposit, i is monthly interest rate (annual ÷ 12) and n is number of months.
What is the minimum RD amount in India?
Most banks allow RDs from ₹100–₹500 per month. Post office RD minimum is typically ₹100 per month for a 5-year scheme.
Is RD better than FD?
RDs suit monthly savers; FDs suit lump sums. RD interest rates are often similar to FDs but compounding works on growing balances each month.
