PPF or Post Office RD: Which offers higher returns over 15 years with a monthly investment of ₹10,000?

If you want to save for the future but are unsure whether a Post Office Recurring Deposit (RD) or a Public Provident Fund (PPF) would be a more beneficial investment, read on.

Nowadays, many people realize that earning an income is not enough; they are increasingly focusing on budgeting as well. Since emergencies can arise unexpectedly, having savings is crucial. Many individuals manage to set aside ₹5,000 or ₹10,000 from their monthly salary, but they often struggle with where to invest these funds to build a substantial corpus for the future.

If you are also saving ₹10,000 every month from your salary and aiming to build a significant fund for yourself and your family, the first step is choosing the right investment scheme. If you are unsure about the best option, let’s explore what might be more suitable for you.

Where should you invest?

The Post Office Recurring Deposit (RD) and the Public Provident Fund (PPF) are two savings schemes that allow for regular investments. The question is: if someone invests ₹10,000 every month, which scheme will yield a larger sum after 15 years—PPF or a Post Office RD?

How much of a fund can be built through a PPF?

The Public Provident Fund (PPF) is particularly well-suited for those who wish to build a large corpus through consistent, long-term investments. As of the October–December 2026 quarter, it offers an interest rate of 7.1 percent. The scheme has a maturity period of 15 years. If you deposit Rs 10,000 every month, your total investment over 15 years will amount to Rs 18 lakh.

Crucially, if the current interest rate remains unchanged for 15 years, the fund could grow to approximately Rs 32.5 lakh at maturity. Notably, about Rs 14.5 lakh of this amount would come solely from interest. However, this figure may change if interest rates fluctuate in the future.

Is investing in a Post Office RD a good choice?

A Post Office Recurring Deposit (RD) is beneficial for those who wish to save by depositing a fixed amount every month. For the October–December 2026 quarter, this scheme offers an annual interest rate of 6.7 percent. The initial tenure is 5 years.

Under the existing rules, the tenure can be extended for another 5 years. If you deposit Rs 10,000 per month, your total contribution would be Rs 6 lakh over 5 years, or Rs 12 lakh over 10 years. Keep in mind, however, that the final corpus will depend on the prevailing interest rate at that time.
