FD vs Savings Account: When to Move Your Money
Understand exactly when keeping money in a savings account makes sense and when an FD delivers significantly better returns — with real numbers.
Your savings account is costing you money. Not literally — but every rupee sitting in savings at 2.70% could be earning 6.50-7.10% in a Fixed Deposit at the same bank. On ₹3,00,000, that's a difference of ₹11,400 to ₹13,200 per year. Money you leave on the table by doing nothing.
But savings accounts exist for a reason. Moving everything to FDs would be a mistake too. Here's how to think about it.
The Rate Gap
Current savings account rates at major banks:
- SBI: 2.70%
- HDFC Bank: 3.00%
- ICICI Bank: 3.00%
- Kotak Mahindra Bank: 3.50% (up to ₹1 lakh; varies above)
Current FD rates at the same banks (1-year tenure):
- SBI: 6.70%
- HDFC Bank: 6.90%
- ICICI Bank: 6.80%
- Kotak Mahindra Bank: 7.00%
The FD rate is roughly 2x to 2.5x the savings rate. This gap has existed for decades and is structural — banks can offer more for FDs because they get guaranteed use of your money for a fixed period.
Real Numbers: ₹5,00,000 Comparison
**Savings account at 3.00%:**
- Annual interest: ₹15,000
- Monthly: ₹1,250
**FD at 7.00% (1-year, quarterly compounding):**
- Annual interest: ₹35,903 (effective rate ~7.19% due to compounding)
- Monthly equivalent: ₹2,992
Difference: ₹20,903 per year. That's a round-trip flight to Goa or a year of streaming subscriptions — earned by simply moving money from one product to another at the same bank.
When to Keep Money in Savings
Not all money should go into FDs. Keep these amounts in your savings account:
- **1-2 months of expenses** — For daily transactions, bill payments, EMIs, and unexpected small costs. If you spend ₹50,000/month, keep ₹50,000 to ₹1,00,000 in savings.
- **Upcoming planned expenses** — Rent due next week? Insurance premium next month? Keep that in savings.
- **Minimum balance requirement** — Most banks require ₹10,000 to ₹25,000 minimum balance. Factor this in.
Everything above this working capital threshold is a candidate for FDs.
When to Move Money to FDs
- **Bonus received**: Annual bonus sitting in savings? Open an FD immediately for 6-12 months.
- **Savings exceeding 2 months' expenses**: Sweep the excess into FDs.
- **Known future expense**: Wedding in 2 years? Put the funds in a 2-year FD instead of letting them idle.
- **After debt repayment**: Finished paying off a loan? The EMI amount that was leaving your account is now surplus — FD it.
The Sweep-In FD Solution
Don't want to choose? Many banks offer sweep-in (flexi) FDs. Money above a threshold in your savings account automatically moves into an FD. If your savings balance drops below the threshold, the FD auto-breaks (partially) to cover it.
- You earn FD rates on surplus money
- You maintain savings account liquidity
- Auto-sweep happens daily or based on your chosen threshold
SBI's Multi Option Deposit, HDFC's Sweep-in FD, and ICICI's iWish are popular options. The rate is typically 0.25-0.50% less than the best regular FD rate, but still far better than savings.
TDS Consideration
Savings account interest up to ₹10,000/year is exempt under Section 80TTA (for non-seniors). FD interest has no such exemption — it's fully taxable and subject to TDS above ₹40,000/year.
On small amounts (under ₹3-4 lakh), the TDS factor rarely negates the higher FD rate. But it's worth being aware of. Senior citizens get a much better deal with Section 80TTB covering ₹50,000 of all deposit interest including FDs.
A Simple Rule of Thumb
Calculate your average monthly expenses. Multiply by 2. Keep that in savings. Move everything else into FDs — use our [FD Calculator](/) to see exactly how much more you'll earn.

The 5 minutes it takes to open an FD online could earn you ₹20,000+ per year on ₹5 lakh. That's probably the highest-ROI 5 minutes of your financial life.
