Short-Term Money: FD vs Liquid Funds vs Arbitrage
When you need to park money for 3-12 months — for a down payment, wedding fund, or tax outgo — the choice of instrument matters more than you think. The wrong option can cost you 1-2% in returns or lock your money when you need it most. This guide compares the four main short-term parking options.
Last updated: 14 May 2026, 5:00 PM IST
You have ₹5-20 lakh that you will need in 3-12 months — maybe for a car down payment, an upcoming wedding, advance tax payment, or a property registration. The default move is to leave it in a savings account earning 3-4%. That is a silent loss of ₹15,000-60,000 per year compared to better alternatives.
This guide compares four short-term parking options — FDs, liquid funds, arbitrage funds, and savings accounts — across returns, taxation, liquidity, and safety. The best choice depends on your tax bracket, exact time horizon, and liquidity needs.

Option 1: Liquid Mutual Funds — Best for 1 Week to 6 Months
Liquid funds invest in money-market instruments (treasury bills, commercial paper, certificates of deposit) with maturities up to 91 days. They are the go-to parking option for short-term idle cash.
- Returns: 6.5-7.0% annualized (not guaranteed, but highly stable)
- Liquidity: T+1 redemption (money in your account next business day). Instant redemption up to ₹50,000 available with select funds
- Exit load: Graded exit load for redemption within 7 days; no load after 7 days
- Taxation: Gains taxed at your income tax slab rate (no indexation benefit)
- Risk: Very low; near-zero probability of capital loss with large-AUM funds
- Minimum investment: ₹500 (most funds)
Best for: Parking emergency funds, idle cash between investments, or money needed within 1-6 months. Not ideal for amounts you need on the same day (use savings account for that).
Option 2: Arbitrage Funds — Best for 3-12 Months (High Tax Brackets)
Arbitrage funds exploit the price difference between cash and futures markets. They earn returns similar to liquid funds (7-8%) but are classified as equity funds for tax purposes, giving them a significant tax advantage.
- Returns: 7.0-8.0% annualized (not guaranteed; depends on cash-futures spread)
- Liquidity: T+1 to T+3 redemption depending on the fund
- Exit load: Most funds charge 0.25-0.50% for redemption within 15-30 days; no load after
- Taxation: Taxed as equity — STCG at 20% (holding under 1 year), LTCG at 12.5% above ₹1.25 lakh (holding over 1 year)
- Risk: Very low; market-neutral strategy. Slightly higher risk than liquid funds due to longer settlement cycles
Tax advantage example: On ₹10 lakh invested for 9 months at 7.5%, an arbitrage fund generates ₹56,250 in gains. Tax at 20% STCG = ₹11,250, leaving ₹45,000 post-tax. The same return in an FD (30% bracket) leaves only ₹39,375. That is ₹5,625 extra on a single ₹10 lakh investment.
Option 3: Fixed Deposits — Best for Guaranteed Returns
FDs are the most familiar option and the only one that guarantees a specific return. For short tenures (3-12 months), FD rates are typically 5.5-7.5% at large banks and 7.5-9.0% at small finance banks.
- Returns: 5.5-7.5% (large banks), 7.5-9.0% (SFBs) — guaranteed
- Liquidity: Premature withdrawal available with 0.5-1.0% penalty on the interest rate
- Taxation: Interest taxed at slab rate. TDS at 10% if interest exceeds ₹40,000/year (₹50,000 for seniors)
- Risk: Zero (DICGC-insured up to ₹5 lakh per bank)
Best for: Risk-averse investors, senior citizens (who benefit from Section 80TTB), and anyone who needs absolute certainty of returns. The premature withdrawal penalty makes FDs less ideal when the exact withdrawal date is uncertain.
Option 4: Savings Account — Only for Immediate Needs
Savings accounts earn 3-4% at most banks (some neo-banks and small finance banks offer 6-7%). The only advantage is instant liquidity — your money is available 24/7 via UPI, debit card, or ATM.
- Returns: 2.7-4.0% (large banks), 6.0-7.0% (select SFBs/neo-banks)
- Liquidity: Instant — available any time
- Taxation: Interest taxed at slab rate. Section 80TTA deduction of ₹10,000 available (Old Regime)
- Risk: Zero (DICGC-insured)
Best for: Monthly expenses and emergency fund only. Any amount beyond 2 months of expenses should be moved to a liquid fund or FD.

- 3-12 months, high tax bracket (20-30%): Arbitrage fund
- 6-12 months, want guaranteed returns: FD at small finance bank

Frequently Asked Questions
What is the best option to park money for 3 months?
Liquid mutual funds are the best option for 3-month parking. They offer 6.5-7.0% annualized returns with T+1 (next business day) redemption and no exit load after 7 days. FDs for 3 months offer lower rates (5.5-6.5%) and charge a premature withdrawal penalty if you need money early. Savings accounts earn only 3-4%.
Are arbitrage funds better than FDs for short-term investing?
For investors in the 20% or 30% tax bracket with a 6+ month horizon, yes. Arbitrage funds earn 7-8% pre-tax and are taxed as equity — STCG at 20% (for holding under 1 year) vs FD interest taxed at 30% slab rate. On a ₹10 lakh investment for 9 months at 7.5%, an arbitrage fund yields ₹45,000 post-tax (at 20% STCG) vs ₹39,375 from an FD (at 30% slab). The catch: arbitrage fund returns are not guaranteed.
Are liquid mutual funds safe? Can I lose money?
Liquid funds invest in very short-term debt instruments (T-bills, commercial paper, certificates of deposit) maturing within 91 days. The risk of capital loss is extremely low but not zero — a few liquid funds saw small NAV drops during the IL&FS crisis in 2018. Stick to funds from large AMCs (SBI, HDFC, ICICI, Axis) with AUM above ₹10,000 crore for maximum safety.
Is a sweep-in FD better than a liquid fund?
Sweep-in FDs offer the convenience of auto-sweeping excess savings account balance into FDs, giving you FD rates with savings-account liquidity. However, sweep-in rates are typically 0.5-1% lower than regular FD rates, and the interest is taxed at your slab rate. For amounts above ₹5 lakh, liquid funds offer comparable or better returns with more favorable tax treatment.
