Post Office RD lets investors build a savings corpus through fixed monthly deposits, with the five-year National Savings Recurring Deposit Account currently offering 6.7% annual interest, compounded quarterly.
If an investor deposits ₹4,000 every month for five years, the total amount deposited comes to ₹2.40 lakh.
At the current 6.7% rate, the maturity amount works out to about ₹2.85 lakh, including roughly ₹45,460 in interest.
Post Office RD Investment Calculation
Post Office RD requires 60 monthly deposits during the standard five-year maturity period.
The minimum monthly deposit is ₹100, while there is no maximum deposit limit under the National Savings Recurring Deposit Account.
For a ₹4,000 monthly investment, the calculation is straightforward. Over 60 months, the investor deposits ₹4,000 × 60, taking the total principal to ₹2,40,000.
At the current 6.7% interest rate, the indicative maturity value is around ₹2,85,460. This means the interest component is approximately ₹45,460 over the five-year period.
How ₹4,000 Monthly RD Grows
The Post Office RD interest rate is compounded quarterly, so the maturity amount is higher than the total amount deposited.
India Post’s calculation method takes the quarterly interest rate and the number of quarters into account when determining the maturity value.
For comparison, the official interest table for the 6.7% rate shows that a ₹100 monthly deposit for five years grows to ₹7,137 against total deposits of ₹6,000.
The ₹4,000 monthly example therefore scales to approximately ₹2.85 lakh, subject to the applicable rate and calculation rules.
The interest rate on small savings schemes is reviewed by the government periodically.
Therefore, investors should check the applicable rate when opening an account or calculating future maturity values.
Post Office RD Rules You Should Know
The National Savings Recurring Deposit Account matures after five years. After maturity, the account can be continued for another five years under the applicable rules.
Investors also need to make their monthly deposits on time. The scheme provides provisions relating to defaults, advance deposits and premature closure, so account holders should understand these conditions before starting their RD.
[[H2: Who Can Consider This Scheme]]
Post Office RD can be used by savers who prefer making regular monthly deposits instead of investing a large amount at one time. The fixed contribution structure can help investors maintain a disciplined savings routine over the five-year term.
However, the final maturity amount depends on the applicable interest rate and the scheme’s rules. Investors should verify the prevailing rate before making financial decisions based on a projected return.
