Where to Keep Your Savings

Once you know which money is savings, the next question is where it should sit. The choice decides three things: whether the money is protected if the institution fails, how quickly you can reach it, and how much it earns after tax. Many people leave savings in the account that came with their checking account, and the rate there is often a small fraction of what other insured accounts pay. This chapter compares the main options and shows what the difference is worth.

What to look for

Every home for savings is a trade-off among four qualities:

• Safety. Is the balance protected, and by whom? For savings, the answer should be deposit insurance or the U.S. government.
• Access. How quickly can you turn it into spendable cash, and is there a penalty for doing so early?
• Yield. How much does it earn? For deposit accounts this is quoted as the annual percentage yield, or APY, which includes the effect of compounding so accounts can be compared directly. Federal rules set how banks must calculate and disclose it.
• Tax. Interest is taxable income. Where it is taxed, federally and by your state, changes what you keep.

No option is best on all four. The right home depends on the job the money is doing.

Deposit insurance

Deposits at an FDIC-insured bank are protected up to $250,000 per depositor, per insured bank, for each account ownership category, if the bank fails. Credit unions insured by the NCUA carry federal share insurance up to the same standard amount. Coverage applies to checking, savings, money market deposit accounts and certificates of deposit.

Three points are worth knowing:

• Ownership categories add up. Individual accounts, joint accounts and certain retirement accounts are separate categories, so a household can have more than the standard amount insured at one bank.
• Investments are not deposits. Stocks, bonds, mutual funds and money market funds are not covered by deposit insurance, even when bought through a bank.
• Apps and fintech accounts vary. Some financial apps hold your money at partner banks. Coverage then depends on the partner bank and on its records showing what belongs to you. Check which bank holds the money, and confirm that it is insured with the FDIC's BankFind tool at banks.data.fdic.gov.

The options compared

High-yield savings account. An ordinary insured savings account, usually at an online bank or credit union, that pays well above the national average. Money is typically available within one or two business days. The rate is variable and can fall when interest rates in the economy fall. It is the usual home for an emergency fund and for goals within a year or two.

Money market deposit account. An insured bank deposit, sometimes with checks or a debit card, and sometimes with a higher minimum balance. Do not confuse it with a money market fund, which is an investment held at a brokerage, not a deposit, and is not covered by deposit insurance, although such funds are designed to hold a stable value and invest in short-term, high-quality debt.

Certificate of deposit (CD). An insured deposit that pays a fixed rate for a fixed term, from a few months to several years. Taking money out early usually costs a penalty of some months' interest. CDs suit money with a known date. A CD ladder, several CDs maturing at intervals, gives regular access while locking in rates.

Treasury bills. Short-term U.S. government debt that matures in a year or less, bought through TreasuryDirect or a brokerage. They are backed by the federal government, and their interest is exempt from state and local income tax. The 26-week bill yielded 4.37% on September 29, 2026, according to the Treasury's daily rates. A bill held in a brokerage account can be sold before it matures, but its price may have moved in the meantime.

Series I savings bonds. U.S. savings bonds whose rate combines a fixed rate and an inflation rate reset every six months, so they protect purchasing power. One Social Security number can buy up to $10,000 in electronic I bonds a calendar year. They cannot be cashed for the first 12 months, and cashing them before five years costs the last three months of interest. They suit money with a horizon of one year or more that you want protected from inflation, not the first layer of an emergency fund.

What the rate difference is worth

The FDIC publishes a monthly national average rate for savings accounts. In September 2026 it was 0.37%. Many online banks were paying several percentage points more. Rates change often, so the second example below uses an assumed rate rather than any bank's current offer.

An emergency fund of $15,000 left at the national average earns about $280 over 5 years. At an assumed 4.0% the same money earns about $3,250, with the same deposit insurance. Moving it is usually a one-time task of an hour or less.

Taxes on interest

Interest from savings accounts, money market accounts and CDs is taxed as ordinary income, federally and in most states, in the year it is credited, whether or not you withdraw it. Your bank reports it on Form 1099-INT. The rate that applies is your marginal rate, the rate on your last dollars of income.

A single filer with gross income of $70,000 in 2026 pays $6,570 in federal income tax on $53,900 of taxable income, before any credits, and reaches the 22.0% bracket. Each extra dollar of interest is taxed at that rate, plus any state income tax. Treasury bills skip the state part, which is why a bill can be worth more after tax than a savings account paying a similar rate, especially in a high-tax state. The HYSA vs T-bill after-tax calculator compares the two with your own rates.

Matching the account to the job

Health savings accounts (HSAs) are a special case that can serve both as savings for medical costs and as long-term investments; chapter 8 explains where they fit.
