What Is The Apy For Money Invested At Eachã¢â‚¬â€¹ Rate?

Key takeaways

Annual percentage yield (APY) is a percentage that reflects the amount of money, or interest, you earn on a bank account over one year.
APY includes compound interest.
You can use a savings calculator to quickly see what you'll earn with a given APY.

APY is short for "annual percentage yield." Almost all savings accounts, and some checking accounts, have one. The higher it is, the faster your money grows.

It's an important term to know for anyone focused on saving more money.

What does APY mean?

APY refers to the amount of money, or interest, you earn on a bank account over one year. Of note, this includes compound interest. An interest rate is similar to APY except it doesn't factor in compounding.

Simple interest doesn't compound, so you earn the same amount of interest every month. Compound interest, meanwhile, is the interest earned on both the money you put into the account and the interest you receive over time.

The higher a savings account's APY, the better. Many online banks offer APYs around 0.40%. (You can read more about some of NerdWallet's favorite high-yield accounts here.) The national average is just 0.06% . See below to compare rates and accounts and find the right option for you.

If you're willing to lock away some of your savings for a set period of time, consider a certificate of deposit, or CD. Some online banks have CD rates around 0.55%. (See NerdWallet's list of the best CD rates .)

How to calculate APY

You can use a formula to manually calculate APY, if you know your account's interest rate:

APY= (1 + r/n )^n – 1,

In which:

r = interest rate n = number of compounding periods (if interest is compounded monthly, this would be 12)

Your bank or credit union could also provide you with your APY.

If you know your APY, you can quickly see what you'll earn in a certain period of time with our savings calculator . You can simply plug in your starting balance, the amount you'd add each month, the amount of time and the APY.

How compound interest works

Compounding occurs in a set period, usually daily or monthly. Interest compounded daily leads to more money than interest compounded monthly.

But it's generally too small to worry about unless you're dealing with large amounts — and even then, it won't make a significant difference. For example, $100,000 in an account with a 0.50% APY earns only $0.10 more in one year when compounded daily instead of monthly. (Read more in our compound interest explainer .)

When shopping around for a new savings account or CD, finding a high APY should be a priority. The higher the rate, the faster your cash will grow.

Is APY variable?

That depends on the savings product. If you have a savings account, your APY is variable, and may increase or decrease based on market conditions. If you have a CD, the rate you have when you sign up is typically the rate you'll receive throughout your term. But if you sign up for another CD later, you may receive a different rate.

When the Federal Reserve increases its benchmark interest rate, the APYs on savings accounts and new CDs tend to increase as well. But when the Fed cuts its benchmark rate, as it did twice in March 2020, those same APYs tend to decrease.

Online banks generally offer the best available APYs regardless of the benchmark rate — even though these institutions tend to cut their APYs when rates are down, they also increase them when rates are up.

The key thing to remember is this: Because online banks offer the best rates on savings accounts, they can help you grow your money faster than traditional brick-and-mortar banks.

Frequently asked questions

APY vs. APR: What's the difference?

APY, or annual percentage yield, is different from APR, or annual percentage rate. Generally, APY refers to interest you'll earn , and APR refers to interest you'll pay.

APY is the percentage rate of the total amount of interest earned on a deposit account, based on the interest rate and the compounding frequency for one year. APR is the percentage rate reflecting the cost of credit for a year.

The national average savings rate is 0.06% APY, but you can easily find rates that are higher than that. Some of the best savings rates come from online banks and are around 0.45%.

The formula to calculate APY accounts for the interest rate and the number of compounding periods there are in a year.

If you know your APY and want to quickly see the amount of interest you'll earn on your balance at that rate, you can use an online tool such as our compound interest calculator .
