Imagine this. Two friends start investing at the same time. Both put aside Rs 5,000 every month. One chooses a safe FD (fixed deposit). The other goes with a SIP (Systematic Investment Plan) in mutual funds. Five years later, they compare results. Who comes out ahead?
The answer isn’t as simple as it may seem.
THE RETURN GAP: SMALL ON PAPER, MEANINGFUL OVER TIME
Over five years, a Rs 5,000 monthly SIP in equity mutual funds can grow to roughly Rs 3.8–4.2 lakh at 10–12% returns. In comparison, an FD or RD may reach about Rs 3.4–3.6 lakh at 6–7%, says Siddharth Maurya, Founder and MD of Vibhvangal Anukulakara Pvt Ltd.
He explains, “A monthly SIP of Rs 5,000 in equity mutual funds can generate better returns than a recurring deposit after five years because of market-based returns, while FDs provide steady but lower growth.”
At first glance, the gap may not feel dramatic. But over longer periods, even small differences in returns can add up meaningfully.
STABILITY VS GROWTH: WHAT MATTERS MORE?
The real difference lies in how these two options behave. FDs are predictable. You know exactly what you will get at the end. SIPs, however, move with the markets and can see ups and downs along the way.
Sachin Jain, Managing Partner at Scripbox, puts it into perspective, “SIP and FD have different objectives. Fixed deposits offer predictable returns, while SIPs depend on markets and may even deliver lower returns in a downturn over five years.”
In other words, one offers certainty, the other offers possibility.
COMPOUNDING: SAME CONCEPT, DIFFERENT PACE
Both SIPs and FDs benefit from compounding, but the journey looks very different. FDs grow at a steady, fixed rate. SIPs, on the other hand, rely on market performance, which can speed up growth over time.
Compounding works in both, but differently. In FDs, interest builds steadily at a fixed rate. In SIPs, returns compound based on market performance, which can accelerate growth over time.
Maurya points out that SIPs benefit from dynamic compounding and rupee cost averaging, where investors buy more units when prices are low, which can improve long-term returns.
Jain offers a simple way to understand the difference, “At 6%, money may take about 12 years to double, while at 12%, it could double in around 6 years.”
But he also cautions, “The full benefits of equity compounding may take more than five years to be realised.”
VOLATILITY: FRIEND OR FOE?
Market swings often make investors uneasy, but for SIPs, they can actually be helpful.
Maurya explains that downturns allow investors to accumulate more units at lower prices, which can boost returns when markets recover. Jain agrees, but adds, “Volatility benefits long-term investors, but over shorter periods like five years, returns can be uneven.”
Put simply, patience plays a big role.
TAX: THE SILENT DIFFERENTIATOR
Taxation can quietly influence your final returns. FD interest is taxed every year based on your income slab, which can eat into gains.
“Interest from Fixed Deposits (FDs) is taxed annually as per your income slab, which can reduce post-tax returns, especially for higher earners,” Maurya says. “In contrast, Systematic Investment Plans (SIPs) in equity mutual funds are taxed only on redemption.”
BEHAVIOUR: THE DECIDING FACTOR
Interestingly, both experts agree that investor behaviour often decides the outcome more than the product itself.
Stopping SIPs during market dips, chasing past winners, or blindly renewing low-interest FDs can all hurt outcomes. As Jain says, “Discipline and consistency are key to making SIPs work over time.”
SO, WHICH ONE SHOULD YOU CHOOSE?
There is no one-size-fits-all answer. If your priority is safety and stable returns, FDs are a better fit. If you are willing to take some risk for higher growth, SIPs can work in your favour.
Maurya sums it up well, “SIPs are better for wealth creation, while FDs are suited for capital protection.”
Back to our two friends, one may end up with higher returns through SIPs, but will have ridden the market’s ups and downs. The other may earn slightly less through FDs, but with far fewer surprises.
In reality, the smarter move may not be choosing one over the other. A balanced approach, i.e., using FDs for stability and SIPs for growth, can offer the best of both worlds.
Because in the end, investing isn’t just about picking the better option. It’s about staying invested, staying disciplined, and letting time do its work.
