RD vs FD vs PPF: Which Is Best for Salaried Savers in India?

A salaried employee with a fixed monthly surplus of ₹5,000 has three obvious, boring, safe options: start a recurring deposit, save up and open a fixed deposit, or put it into PPF. All three are backed by either a bank or the government. None of them will make headlines. But they behave very differently depending on how you use them, and picking the wrong one for your actual goal wastes years of compounding.

What each of these actually is #

A recurring deposit (RD) lets you deposit a fixed amount every month for a chosen tenure, at a fixed interest rate, ideal when you don't have a lump sum but do have steady monthly savings capacity.

A fixed deposit (FD) requires a lump sum upfront, locked for a chosen tenure at a fixed rate. It's the right tool when you already have the money sitting idle and want it doing something safe.

PPF (Public Provident Fund) is a government-backed, 15-year lock-in scheme with a current government-set interest rate (revised quarterly), plus a valuable tax benefit: contributions qualify for Section 80C deduction, and the entire maturity amount, including interest, is tax-free.

Worked example: same monthly commitment, three instruments #

Assume ₹5,000 a month of savings capacity, compared across a suitable tenure for each instrument.

RD: ₹5,000/month for 5 years at 6.5%, compounded quarterly

• Total deposited: ₹3,00,000
• Maturity value: ₹3,54,954
• Interest earned: ₹54,954

FD: ₹3,00,000 lump sum for 5 years at 7%, compounded quarterly

• (Assuming the same total amount was saved up first, then deposited as one lump sum)
• Maturity value: ₹4,24,433
• Interest earned: ₹1,24,433

PPF: ₹60,000/year (≈₹5,000/month) for 15 years at 7.1%

• Total deposited: ₹9,00,000
• Maturity value: ₹16,27,284
• Interest earned: ₹7,27,284, entirely tax-free

The FD outperforms the RD here because the full amount earns interest from day one, while RD deposits build up gradually and each instalment only earns interest for its remaining period. But this comparison only works if you actually have ₹3,00,000 sitting idle to begin with, which is precisely the situation most salaried savers don't have. The PPF number looks the biggest, but it's locked for three times as long and isn't really the same comparison.

Where each one actually wins #

• RD wins when you don't have a lump sum. It's the only one of the three that lets you start with just your monthly salary surplus, no upfront capital required.
• FD wins when you have idle lump sum cash and want a fixed, predictable return without monthly discipline required.
• PPF wins on pure returns and tax efficiency, but only if you don't need the money for 15 years (partial withdrawal is allowed from year 7, with conditions). It's better suited to long-term goals like retirement or a child's higher education than short-term savings.

Common mistakes people make choosing between them #

1. Comparing PPF's 15-year return against a 5-year FD and concluding PPF is "better," without accounting for the massive difference in lock-in period. Longer money always looks bigger.
2. Starting an RD when they actually had lump sum cash available. If you already have the money, an FD usually beats an RD at the same tenure, since the entire amount earns interest immediately.
3. Forgetting FD interest is fully taxable while PPF interest is completely tax-free. A 7% FD in the 30% tax bracket earns roughly 4.9% after tax, while PPF's 7.1% stays 7.1% in your pocket.
4. Breaking a PPF account plan too early mentally. Many people avoid PPF thinking they can't touch it for 15 years at all, when partial withdrawals are actually permitted from the 7th year onward under specific rules.

Tips for choosing the right instrument #

• Match the tenure to your actual goal. A 2-year goal (like a vacation fund) doesn't belong in a 15-year PPF account.
• Use RD for goals 1 to 5 years out where you're saving monthly rather than sitting on a lump sum already.
• Use FD for idle lump sums you won't need for a defined period, especially useful as an emergency fund component since it's easy to break if needed.
• Use PPF for long-term, tax-advantaged goals like retirement or your child's education fund, and start it as early as possible since the 15-year clock only benefits you once it's running.
• Ladder your FDs and RDs across different tenures so you're not stuck waiting for one large maturity date, and instead have money freeing up periodically.
• Don't treat PPF as your only long-term instrument. It caps contributions at ₹1,50,000 per year, so once you've maxed that out, equity mutual funds through SIPs are usually the next step for long-term goals beyond what PPF alone can hold.

A word on combining all three #

Most salaried savers don't need to pick just one. A practical structure looks like: an RD or short FD for near-term goals and topping up your emergency fund, a PPF account maxed out annually (or as close to ₹1,50,000 as your budget allows) for the guaranteed, tax-free long-term portion of your portfolio, and equity mutual funds for the remainder of your long-term savings once PPF's cap is reached. None of these three compete with each other once you think in terms of "which goal is this money for," rather than "which single instrument is best."

Model your own numbers with the RD calculator, the FD calculator, and the PPF calculator to see which one actually fits the money you have and the timeline you're saving for. Try a real comparison like ₹5,000/month RD for 5 years against a ₹1,00,000 PPF contribution over 15 years to see the tradeoff in your own numbers.

Frequently asked questions #

Which is safer, RD, FD, or PPF? #

All three are considered extremely safe. Bank RDs and FDs are insured up to ₹5 lakh per depositor per bank under DICGC. PPF is a direct government-backed scheme with no insurance cap needed, since it's sovereign-guaranteed.

Can I break a PPF account before 15 years? #

Partial withdrawals are allowed from the 7th financial year onward, subject to limits based on your balance. Full premature closure is only allowed in specific cases like medical emergencies or higher education needs, and it comes with a reduced interest rate as a penalty.

Is RD or FD better for a short-term goal? #

If you already have the lump sum, FD generally gives a better return since the full amount earns interest from day one. If you're building up savings monthly rather than starting with a lump sum, RD is the more practical choice.

Do I have to pay tax on RD and FD interest? #

Yes, interest from both RD and FD is fully taxable at your income tax slab rate, and banks deduct TDS if annual interest crosses ₹40,000 (₹50,000 for senior citizens). PPF interest, by contrast, is entirely tax-free, which is a meaningful edge for anyone in a higher tax bracket comparing the three side by side.

Use the calculators to run your own comparison before you decide where the next ₹5,000 of your salary goes, since the "best" option genuinely depends on whether you have a lump sum, how soon you need the money, and whether you can commit to a 15-year lock-in.
