13 Best Savings Accounts with Compound Interest

Growing savings account

Whether you’re building an emergency fund or saving up for a large expense, it is always best to keep some cash on hand. One of the best ways to grow and protect your money is to save inside accounts with compound interest.

Stowing your money in a compound-interest savings account will allow you to earn interest without having to jump through hoops to access your funds. Plus there are many options for high-interest savings accounts. You can go with a traditional FDIC-insured bank, an FDIC-insured online bank, or an NCUA-insured credit union.

To help you kick-start your savings goals and reach financial independence quicker, we’ve compiled a list of the best accounts with compounding interest.

How do you determine the best high-yield savings accounts?

When evaluating the best accounts for earning interest, look at the annual percentage yield (APY), fees, ease of use, and accessibility.

There are hundreds of savings accounts offered by credit unions, online banks, and brick-and-mortar banks. The question is, how do you choose the best account for your needs? Here are the factors to consider when selecting a savings account with compounding interest:

  • APY: The higher the APY, the faster your money will grow. It’s important to be aware that APY, unlike APR, does take compounding into account. For this reason, it’s best to compare APYs when looking at accounts.
  • Ease of use: The savings account you choose should be easy to navigate. The terms and conditions should be easily understandable as well.
  • Fees: Some banks charge a monthly maintenance fee and other costs that could reduce your interest earnings, so pay close attention to the fees charged.
  • Account accessibility: Your savings account should also be easily accessible. Scheduling your initial deposit, checking your balance, and even withdrawing the funds should be as seamless as possible and in sync with your personal preferences (e.g. online transfers versus in-person ATMs).

What is compound interest?

Put simply, compound interest is the interest earned on interest. With compound interest, you earn interest on both the principal (initial deposit you saved) and the interest that you have already accumulated over time. 

Whenever you deposit money in a savings account or any other similar account, you earn interest based on that contribution. For instance, if you save $1,000 in an account that pays 1% interest per annum, you would earn $10 in simple interest at the end of that year.

With compound interest, in year two you will earn 1% of $1,010 一 the initial amount plus the interest accrued during year one. Your interest earnings grow more quickly with compounding interest, and so do your savings in the long run.

Different accounts compound interest on different schedules; some compound daily, and others weekly or monthly. In general, the shorter the compounding period the better – and this is something you must account for when using APRs. APYs, on the other hand, account for differences in compounding schedules, making them a simpler measure for comparison.

Why is a compound interest account important?

You don’t just need a checking or savings account, you need a compounding interest account. Why is that? The simple reason is that compound interest gives you the chance to grow your money faster. How much interest you earn will depend on several factors, including how much you save in the first place. The nature of your savings account is another key determinant.

A compound interest account pays interest on both the money you invest and the interest you already accrued at the end of every compounding period. This will help your money grow faster, and allow you to reach your financial goals much quicker. 

Accounts with compound interest are among the best ways to protect yourself against inflation, the rising cost of living, reduced purchasing power, and other financial challenges.

Compound Interest Topics

Simple interest or compound interest?

As an investor, it’s important to understand the underlying principles of both simple interest and compound interest. Simple interest is calculated differently from compound interest.

With simple interest, the interest earned is based on the principal amount only. The interest you have already accrued is not taken into account in the simple interest calculation.

Using the previous $1,000 example, if you were earning 1% in annual simple interest, all you would be entitled to is $10 of interest each year. This $10 is not added to the principal and thus does not increase the amount of your interest earnings over time.

For your interest-earning accounts, you want them to be calculated with compound interest. This enables your savings account balance to grow faster as you earn interest on an increasingly larger balance.

Simple interest is mostly used when calculating interest on short-term consumer loans such as personal loans and auto loans. Credit card companies, on the other hand, charge compound interest which is why credit card debts can grow so easily.

What is the compound interest formula?

To understand how compound interest works, it’s important to know the compound interest formula. Several key factors go into calculating compound interest, and the variables drastically affect your returns. The compound interest formula is:

A = P(1 + [r/n]) ^ nt

A – this is the amount of money that accumulates after n years, including the interest from the previous compounding period.

P – The starting principal amount you deposited or borrowed. The more money you deposit, the faster your savings accelerate.

r – This is the annual interest rate, expressed as a decimal. The higher the interest rate, the more money you stand to earn.

n – This is the frequency of compounding, i.e., how many times the interest is compounded in a year. If interest is compounded often, like daily or monthly, your balance can grow rapidly.

t – The time or number of years the money compounds in the account. The longer you leave your money in the account, the more it compounds and the more money you earn.

Other examples of accounts with compound interest

Join a credit union

Credit unions are financial institutions owned by the members of the union. They are mostly non-profit entities looking to serve the aims of their members. They typically offer lower loan rates and better savings account rates. Joining a credit union can be an effective way to access accounts with compound interest.

There is a catch, though. To join a credit union, you must meet certain requirements. These requirements depend on the credit union and how it’s organized. Most of them will require you to be part of a specific group such as a labor union, live in a particular area, or work for a particular employer.

Money market accounts

A money market account is a special type of savings account at a bank or credit union. Money market accounts typically pay higher interest rates compared to traditional savings accounts. They also come with check-writing and debit card privileges, but you have limited access to your money.

The bank or credit union pays you a high-interest rate, but you must deposit a certain amount and keep your account balance above a certain level. If the balance falls below the minimum, a monthly fee is imposed. Money market accounts should be among your options, but ultimately the decision depends on your short-term cash needs, savings timeline, and deposit amount.

How else can I earn compound interest?

Build a CD ladder

Building a CD ladder involves investing in many certificates of deposit with staggered maturities. This way, you benefit from the high rates on longer-term CDs while keeping some of your money accessible in short-term CDs. These staggered maturities give you the potential to make more money by reinvesting in longer-term CDs.

Buy dividend-paying stocks

Dividend stocks are publicly traded companies that share their profits with shareholders via regular dividends. To earn dividends on a stock, you must own shares in that company, either through a brokerage account or a retirement account such as Roth IRA. By reinvesting your dividends, which many brokers enable automatically, you can effectively gain compound interest on the company’s dividend schedule.

Zero-coupon bonds

A zero-coupon bond is a type of bond that doesn’t pay interest. Instead, they trade at a discount to their face value. These savings are realized over the lifetime of the bond, as the “coupons” are effectively reinvested instead of paid out as interest.

Zero-coupon bonds are based on the time value of money. This concept illustrates that money is worth more now than an identical amount in the future. Most zero-coupon bonds are compounded semi-annually.
