The shelf

Everything you can put money into sits on one shelf, and most of the confusion in personal finance comes from comparing two things that are not for the same job.

Here is the shelf, with what each thing is actually for.

Cash and deposits

Savings account, sweep-in, fixed deposit, recurring deposit.

For: money you will need soon, or must not lose. The emergency fund lives here.

Costs: purchasing power. Chapter 7 did the arithmetic — at a 30% slab with 6% inflation, a 7% deposit loses about 1% a year in real terms.

Worth knowing: DICGC insures ₹5,00,000 per depositor per bank, principal and interest together, aggregated across branches. Amounts above that belong at more than one bank.

Government-backed schemes

PPF, EPF, NPS, the post office schemes.

For: long-horizon money, usually retirement, usually with a tax advantage attached.

Costs: access. Lock-ins are long, and that is the deal rather than a defect — you trade liquidity for a better after-tax return than an equivalent deposit.

Worth knowing: the tax treatment often matters more than the rate. Tax-free 7.1% beats taxable 7% by about two percentage points of real return at a 30% slab.

Bonds and debt funds

Government securities, corporate bonds, debt mutual funds.

For: income, and a holding that behaves differently from equity when equity falls.

Costs: two risks people underestimate. Interest-rate risk — when rates rise, the price of what you already hold falls, and the longer the maturity the harder. Credit risk — the borrower may not pay.

Worth knowing: a bond's coupon rate and its yield are different numbers, and the yield is the one that tells you what you are earning.

Equity

Shares directly, or through funds.

For: long-horizon growth, and the one holding that has historically kept ahead of inflation over long periods — with no guarantee that it will continue to.

Costs: volatility you have to sit through, and the possibility of permanent loss in any single company.

Worth knowing: the horizon decides whether it is appropriate, not your opinion of the market. Chapter 9's arithmetic is the reason.

Mutual funds and ETFs

Not a separate asset class — a wrapper. A fund holds equity, debt or both, and what matters is what is inside it, what it charges, and whether it is doing something you could not do more cheaply yourself.

Worth knowing: the expense ratio is charged every year, on the whole balance, whether the fund did well or badly.

Gold

For: a hedge, and a cultural asset held by most Indian households in some form.

Costs: more than the rate quoted. Making charges and tax sit between the price and your bill, and none of that comes back when you sell.

Worth knowing: physical jewellery, coins, digital gold, ETFs and bonds are very different products with very different costs — and only one of them is also a necklace.

Property

For: a home to live in, or rental income.

Costs: everything is bigger — the ticket, the leverage, the transaction costs, the illiquidity, the concentration. Selling takes months and costs percent, not basis points.

Worth knowing: a house you live in is a lifestyle decision with a financial tail, not an investment you happen to sleep in.

The question that sorts the shelf

Not "what returns most". This one:

When will I need this money?

• Under three years — deposits, and nothing that can fall 30%.
• Three to seven years — mostly debt, with equity only for the part you could postpone.
• Over seven years — equity can do its work, if you will actually leave it alone.

Horizon first, then risk you can survive, then tax treatment, then return. Most people run that list backwards and start with the return, which is how money needed next year ends up somewhere it can halve.

What is not on the shelf

Anything promising a high return with certainty. Chapter 9 explained why that combination cannot exist — and in practice, the promise is the warning.

The point

Each thing here does one job well and others badly. Match the job to the horizon before you compare any two returns.
