If you’re going to invest ₹1.5 lakh annually towards your future, the question is this: Do you opt for the market-linked excitement of a Systematic Investment Plan (SIP) or the stable, government-guaranteed security of a Public Provident Fund (PPF)? Both are popular long-term investment options in India, but they work very differently, provide different advantages, and suit different types of investors. Then, which one will enable you to create a larger corpus within a 20-year span?
Let’s look at the actual numbers in this money showdown and see which approach may bring you to financial freedom.

Investment Flexibility: The First Big Difference
SIP and PPF showcase distinct investment flexibility as one of their most noticeable differences. The process of making consistent investments in mutual funds through SIPs displays exceptional versatility. The ability to initiate or terminate your SIP at will allows you to decide both the investment amount and duration according to your personal objectives. SIP allows investors to manage their investment duration whether they prefer short-term commitments of a few months or long-term engagements spanning decades.
Conversely, PPF mandates an inflexible lock-in duration. A mandatory commitment period of at least 15 years is required. The seemingly strict nature of this approach actually instills discipline while guaranteeing uninterrupted growth for your investment. An initial period of 15 years must pass before you can choose to prolong the term in increments of 5 years. Your financial flexibility faces severe limitations during this time frame which leads us to our subsequent discussion point.
Liquidity: Access to Your Money
SIP emerges as the dominant force in liquidity management. Investors can redeem their mutual fund units within one or two working days because these funds are market-linked and managed by fund houses. The adaptable nature of SIPs makes them an ideal selection for individuals who require potential fund access during emergencies or when priorities change.
PPF structures itself as a long-term savings vehicle meant for retirement planning which results in its extremely restricted liquidity options. Only after completing the seventh year can you make partial withdrawals, which remain subject to strict limitations on the permissible amount. The ability to perform a complete withdrawal becomes available exclusively upon reaching the 15-year maturity threshold. Those seeking financial adaptability may find PPF’s constraints somewhat limiting.
Returns: Fixed vs. Market-Linked Growth
Yet another fundamental difference is the nature of returns. PPF provides a guaranteed annual interest rate, which stands at 7.1% currently, and is modified by the government every quarter but remains stable otherwise. This stability renders PPF one of the safest and most predictable investment options in India, particularly for risk-averse investors. Check out for more information about PPF
SIP returns, however, are linked to the performance of mutual funds. These can be equity-based, debt-based, or a combination of both (hybrid). Ups and downs in the market have a direct bearing on your returns, so SIPs do involve some risk. But in the long term, and particularly with a 20-year horizon, SIPs have tended to outperform fixed-return instruments in corpus growth overall.
So What Happens If You Invest ₹1.5 Lakh Every Year for 20 Years?
Let’s now walk through a real-world scenario. Suppose you invest ₹1.5 lakh annually—roughly ₹12,500 each month—over a span of 20 years. We’ll assume that the PPF continues to offer a steady 7.1% interest rate annually. For SIPs, we’ll explore three possible return scenarios: 8%, 10%, and 12%, compounded annually.
Under the PPF model, your total investment over two decades would be ₹30 lakh. With compound interest working its magic year after year, your money would grow to approximately ₹66,66,783 by the end of 20 years. This includes an impressive ₹36,66,783 in interest earnings, all of which are tax-free—a major perk of the PPF scheme.
Now, let’s see how SIPs fare in comparison.
If you choose a debt-oriented mutual fund and achieve an annualized return of 8%, your final corpus would amount to ₹71,10,540. That’s about ₹4.4 lakh more than what PPF delivers, thanks to the higher compounding effect of market-linked returns—even at the lower end of the spectrum.
At a 10% annual return, which is often achievable with a moderately aggressive equity mutual fund, your investment balloons to ₹90,40,229 over the same period. That’s a solid ₹60 lakh in capital gains, showing how market exposure, when managed wisely, can significantly boost long-term wealth.
But if you go for a slightly more aggressive portfolio and consistently earn 12% returns—a figure seen in well-performing equity funds over long periods—your wealth can reach a whopping ₹1,15,53,262 by the end of 20 years. Here, the capital gains alone amount to more than ₹85 lakh, nearly tripling your initial investment.
💹 Corpus Growth Comparison: SIP vs PPF (₹1.5 Lakh/Year for 20 Years)
| Investment Type | Annual Return Rate | Total Investment (20 Years) | Estimated Corpus | Capital Gains / Interest Earned |
| PPF | 7.1% (fixed) | ₹30,00,000 | ₹66,66,783 | ₹36,66,783 |
| SIP (Debt Fund) | 8% (annualized) | ₹30,00,000 | ₹71,10,540 | ₹41,10,540 |
| SIP (Equity Fund) | 10% (annualized) | ₹30,00,000 | ₹90,40,229 | ₹60,40,229 |
| SIP (Hybrid Fund) | 12% (annualized) | ₹30,00,000 | ₹1,15,53,262 | ₹85,53,262 |
Tax Benefits: A Small but Vital Detail
Both PPF and SIP investments offer tax advantages under Section 80C of the Income Tax Act. You can claim deductions of up to ₹1.5 lakh per annum. However, while PPF returns and maturity proceeds are completely tax-free, SIP returns are subject to capital gains tax depending on your holding period and fund type. So, while SIPs may deliver higher growth, they may also come with a modest tax liability.
So, Which One Should You Choose?
The answer isn’t as straightforward as picking the highest number. It really depends on your financial personality. If you prefer stability, guaranteed returns, and long-term discipline, then PPF remains one of the best instruments to safeguard and grow your savings—especially when you want predictability in your retirement corpus.
However, if you’re open to calculated risks and want to maximize returns through equity or hybrid mutual funds, SIPs can significantly outpace PPF over the long term. The flexibility, liquidity, and potential for higher returns make SIPs a powerful tool for wealth creation.
In fact, many savvy investors choose to combine both strategies—using SIPs to fuel aggressive growth while allocating a portion to PPF for steady, risk-free compounding. This kind of diversified approach can help balance risk while securing your future. Check Retirement Calculator
