How to Earn More from Your Idle Cash with Smarter, Safer Alternatives

There was a time early in my career as a Certified Financial Planner when I believed parking money in a savings account was the safest and most reasonable thing to do. I advised my clients to keep a certain portion liquid, often recommending savings accounts or fixed deposits. But over time—and with deeper experience—I realised that playing it too safe often meant missing out on smarter, more tax-efficient, and higher-yielding alternatives.

Many of my clients today—senior professionals, business owners, young couples, and retirees—come to me with a familiar problem: “Taresh, I have this idle cash sitting in my bank account. What should I do with it?”

They’re often not looking to invest in the stock market or mutual funds for long-term growth. Instead, they want short-term parking options—places where their money is safe, liquid, accessible, and still earns decent returns.

And that’s where this conversation begins.

Why Parking Idle Money Needs Strategy

Let’s start with the basic truth: savings account interest rates have dropped to as low as 2.7–2.75% in major banks. At this rate, your money is not even keeping up with inflation, which means you’re actually losing purchasing power over time.

When you’re earning so little from your parked funds—and still paying tax on that income—it’s time to rethink where and how you’re keeping that money.

What Options Do You Really Have?

Over the past few years, I’ve reviewed countless alternatives for short-term and ultra-short-term investments. The goal: higher returns, low risk, easy liquidity, and better tax treatment.

Here’s a simple summary of what I advise my clients:

1. Major Bank Savings Accounts (Return: 2.7–2.75%)

This is the default option for most people. It’s convenient, no doubt—but it offers low returns, taxed at your slab rate, and while it’s safe, your money is doing almost nothing here.

When I recommend this: Only for emergency funds or amounts needed within the next 30 days.

2. Other Bank Savings Accounts (Return: 4–6%)

Some smaller banks offer higher interest rates, but they come with the inconvenience of opening new accounts, managing multiple logins, and a deposit insurance limit of ₹5 lakh per bank under DICGC.

My experience: Some clients are okay with this option, especially retirees looking for slightly higher passive income. But I always remind them about operational hassle and insurance limits.

⸻

3. Fixed Deposits (FDs) (Return: 5–8%)

Still a favourite among traditional investors. FDs are safe and predictable, but they come with penalties on premature withdrawal and, again, interest is taxed at the slab rate.

When I use this: For clients above 60, where safety is paramount, and when they are in a lower tax bracket.

⸻

4. Sweep-in FDs (Return: 5–7%)

These work like auto-upgraded savings accounts. Idle balance beyond a threshold is auto-transferred to a fixed deposit and earns better returns.

Downside: The premature withdrawal penalty still applies, and the tax remains the same.

My use case: Ideal for business clients who want both liquidity and some extra return on idle funds.

⸻

5. Liquid Funds (Return: 5–6%)

This is where the real shift begins. Liquid mutual funds invest in short-term instruments like treasury bills, commercial paper, etc., and offer better returns than savings accounts with comparable liquidity (1–2 working days).

However: NAVs can fluctuate, and the returns are taxed at the slab rate. But the real advantage is zero TDS for resident Indians.

When I recommend: For idle funds beyond 30 days, especially for clients in the higher tax bracket or with large amounts parked temporarily.

⸻

6. Arbitrage Funds (Return: 5–6%)

These are hybrid funds that buy and sell the same stock in different markets, profiting from price differences. Though technically equity-oriented, they behave like debt funds.

Why I love them: Gains after 1 year are taxed at only 10% (LTCG), and before that at 15% (STCG), making them far more tax-efficient than FDs or liquid funds.

For whom: Professionals with high tax slabs or HNIs looking for short-term parking with tax savings.

⸻

7. Debt-Like Hybrid Funds (Return: 6–8%)

These include funds like Debt + Arbitrage Funds. They offer higher yields but also come with higher volatility, so they’re not ideal for very short-term parking.

My use case: Suitable for funds that are not needed for the next 12–24 months and for investors who can stomach minor fluctuations.

But What About Tax?

Here’s where it gets interesting.

If you invest in a mutual fund and follow the right withdrawal strategy, you could significantly reduce your taxable income. Here’s how I explain it to my clients:

FIFO System:

Withdrawals are treated as part capital and part gain. Only the gain portion is taxed—not the full amount you withdraw.

Set-Off Rule:

You can offset gains from mutual funds with capital losses from other investments.

Carry Forward:

Capital losses can be carried forward for up to 8 years to adjust against future capital gains.

⸻

Example from My Client Files:

One of my senior professional clients invested ₹5 lakh in an arbitrage fund. A few months later, it grew to ₹5.5 lakh. He needed ₹1 lakh urgently. We withdrew ₹1 lakh—but only ₹10,000 of it was considered capital gain and thus taxable.

Compare that to an FD withdrawal, where the entire ₹1 lakh could be considered interest income and taxed at slab rate.

That’s a massive difference in tax liability.

What You Should Check Before Investing in Mutual Funds

When I recommend any fund to my clients, I ask them to pause and evaluate these three key points:

1. Fund Portfolio Composition:

Is the fund investing in safe instruments? Does it carry credit or interest rate risk?

2. Exit Load and Lock-In:

Some funds have exit loads if redeemed before 1 week or 1 month. Always check.

3. Performance vs. Category Average:

Don’t just chase past returns. Compare the fund’s consistency against its peers.

How I Coach My Clients to Make These Decisions

Every week during my one-on-one sessions and masterclasses at The Richness Academy, I get asked:

“Taresh, what’s the best place to park my idle money?”

There’s no one-size-fits-all answer. Instead, I walk them through a decision framework:

Question Guided Approach

How long can you keep the funds parked? < 30 days = Bank; 30-180 days = Liquid/Arbitrage funds

What is your tax bracket? High tax = Consider arbitrage funds for tax efficiency

Do you need instant liquidity? Bank or sweep-in FD; else liquid funds (1-day redemption)

Can you tolerate minor fluctuations? Arbitrage or hybrid funds may work for higher returns

Do you want TDS-free returns? Mutual funds have no TDS for resident investors

⸻

My Personal Recommendation Strategy

I typically break down idle money into three buckets for my clients:

1. Emergency Liquidity (Immediate Needs):

Keep 2–3 months of expenses in a major bank or sweep-in FD.

2. Tactical Liquidity (1–6 months):

Park in liquid or arbitrage mutual funds with easy redemption.

3. Strategic Liquidity (6–24 months):

Hybrid or arbitrage funds with tax-efficient withdrawal strategies.

This strategy allows your money to stay safe, stay liquid, and grow tax-efficiently.

The Richness Way: Don’t Let Idle Money Stay Lazy

Money is a powerful energy—and just like us, it needs direction and purpose. Leaving it idle in a low-interest account is like letting it nap through its most productive years.

My role as your financial coach is not just to help you invest for the long term but to help you manage even the short-term opportunities smartly.

Remember, wealth creation is not just about how much you earn, but also about what you do with every rupee sitting idle.
