Fixed deposits are India's most beloved savings instrument. They're familiar, predictable, and feel safe. The interest shows up in your statement, and there's nothing complicated to understand. But "familiar" and "safe" are doing a lot of work in that sentence — and they're obscuring some important disadvantages.
The most important one is tax. FD interest is added to your income and taxed at your slab rate. For someone in the 30% bracket, a 7.5% FD earns effectively around 5.25% after tax. Once you account for inflation running at 5–6%, your real return is barely above zero — or sometimes negative.
A guaranteed savings plan like the Kotak Assured Savings Plan works differently. Returns are locked in at policy inception — you know exactly what you'll receive at maturity. The maturity payout is tax-free under Section 10(10D). And you also get a life cover running through the entire policy term.
The trade-off is liquidity and lock-in. An FD can generally be broken early with a minor penalty. A savings plan has a policy term you commit to, and surrendering early has costs. So it's not the right vehicle for your emergency fund — but for goal-based, medium-to-long-term savings with a guaranteed outcome, it competes very favourably with an FD on an after-tax basis.
The honest answer: both have a place. FDs for short-term liquidity. Savings plans for medium-to-long-term goals where you want certainty and tax efficiency.
