Many people keep savings in the same bank as their checking account, earning almost nothing. Moving it is one of the easiest money wins there is.

What APY means

APY, annual percentage yield, is what your money earns in a year including compounding. It is the number to compare between accounts. Banks are required to disclose it under federal truth-in-savings rules.

The FDIC publishes the national average savings rate every month. High-yield accounts, often at online banks, usually pay several times that average.

Calculator: how big your emergency fund should be

An emergency fund is sized by what you spend, not by what you earn.

Three months already changes life for someone with steady income. Freelancers usually need six. Starting small and not stopping beats waiting for a big surplus.

How much the difference is

With $5,000 saved for a year:

Same money, same effort, $180 more. Rates change, so use your own numbers in the calculator below or the Investor.gov compound interest calculator.

Is it safe?

Check that the bank is insured. FDIC deposit insurance covers up to $250,000 per depositor, per insured bank, per ownership category. Many apps are not banks themselves, so find the partner bank's name before depositing.

Fine print to check

A high-yield account is for money you may need soon: emergency fund and sinking funds. Money for goals ten years away usually belongs somewhere else.

Frequently asked questions

Is a high-yield savings account safe?

If the bank is FDIC-insured (or the credit union is NCUA-insured), deposits are protected up to $250,000 per depositor, per institution, per ownership category.

Can the rate change?

Yes. Savings rates are variable and usually move with the Federal Reserve's rate decisions.

Is it good for an emergency fund?

It is one of the best places: the money is safe, earns interest and can be moved to checking in a day or two.

Do I pay taxes on the interest?

Yes, interest is generally taxable income. The bank sends a Form 1099-INT when interest reaches the reporting threshold.
