At an example 4.00% APY, $10,000 earns about $400 a year in a high-yield savings account, compared with about $40 at 0.40% in a regular one. Over five years, that’s about $2,167 versus $202. Rates change, so compare current APYs.
What $10,000 earns over time
Using example rates of 0.40% APY for a regular account and 4.00% for a high-yield one:
| Years | Regular (0.40% APY) | High-yield (4.00% APY) |
|---|---|---|
| 1 | $40 | $400 |
| 3 | $120 | $1,249 |
| 5 | $202 | $2,167 |
Saving $200 a month for five years instead: you’d deposit $12,000 and earn about $119 of interest at 0.40% or $1,236 at 4.00%.
What makes an account “high-yield”
There’s no official definition; it simply means the account pays a much higher APY than the typical savings account. You can see the FDIC’s national average savings rate to compare. High-yield accounts are often offered by online banks and some credit unions, which have lower costs.
What to check before you open one
- Insurance: FDIC insurance for banks or NCUA insurance for credit unions, which covers up to $250,000 per depositor, per institution, per ownership category.
- APY and how often it changes: savings rates are variable and can go up or down.
- Fees and minimums: a monthly fee or a high minimum balance can wipe out the extra interest.
- Access: how fast transfers reach your checking account, and any limits on withdrawals.
When it’s the right place, and when it isn’t
- Good for: your emergency fund, sinking funds and goals within a few years.
- Less useful if you carry card debt: earning 4% while paying 22% on a card loses money; paying down the card usually comes first, after a small cushion.
- Not designed for long-term growth: savings accounts protect money you’ll need; they’re not meant to beat inflation over decades.
How the interest is paid
Most savings accounts calculate interest daily and add it to your balance once a month. At the example rates, here’s what a typical month adds:
| Balance | Per month at 0.40% APY | Per month at 4.00% APY |
|---|---|---|
| $5,000 | $1.66 | $16.37 |
| $10,000 | $3.33 | $32.74 |
| $25,000 | $8.32 | $81.84 |
How to switch without problems
- Open the new account and link it to your checking account.
- Send a small test transfer and check how long it takes to arrive.
- Move the rest, but leave enough in the old account to cover anything still linked to it.
- Update automatic transfers so new savings go to the new account.
- Close the old account only once nothing depends on it.
More questions
How do high-yield savings accounts work?
Just like regular savings accounts: you deposit money and earn interest, usually compounded daily or monthly. The difference is the higher APY.
Are high-yield savings accounts safe?
If the bank is FDIC-insured or the credit union is NCUA-insured, your deposits are covered up to $250,000 per depositor, per institution, per ownership category.
How much interest does $10,000 earn in a high-yield savings account?
About $400 a year at 4.00% APY, or roughly $33 a month. At 0.40%, it’s about $40 a year.
Can I lose money in a high-yield savings account?
Not from the account itself, within the insurance limits. The rate can drop, and fees can reduce what you earn, so read the terms.
The bottom line
For money you’re saving rather than investing, a high-yield account can earn about ten times more than a regular one at the example rates. Check the insurance, fees and current APY, and keep paying down high-interest debt first.
