Understanding how your savings grow is important, especially if you’re managing rental property finances. Whether you’re setting aside money for repairs, building reserves, or planning future investments, the type of account you choose will affect your returns. 

Learning about APY on a savings account is a key step in deciding where to keep your savings and how to make your money work harder over time.

Key takeaways

  • APY stands for Annual Percentage Yield and includes the effects of compound interest.
  • Compound interest allows you to earn interest not just on your initial deposit but also on the accumulated interest.
  • APY provides a more accurate picture of your total annual earnings compared to a simple interest rate.
  • High-Yield Savings Accounts (HYSAs), often offered by online providers, typically offer much higher APYs than traditional bank savings accounts.
  • Understanding APY is vital for maximizing the growth of your savings over time.

What is Annual Percentage Yield (APY)?

APY refers to how much interest your money earns in one year, including the power of compounding. This means it reflects not just the interest rate itself, but how often that interest is calculated and added to your balance. It is a standardized measure used by financial institutions to show how much interest your money will earn.

Understanding APY allows you to compare different savings options accurately. When comparing two accounts, the one with the higher APY will generally yield greater earnings over a year, assuming all other factors are equal.

APY vs interest rate: What’s the difference

While often used interchangeably, APY and interest rate are two different concepts. 

  • The interest rate is applied only to the original principal and does not include interest earned on previous interest.

  • APY includes compounding, giving a more accurate picture of your yearly growth.

  • APY is used to show earnings on deposits, while Annual Percentage Rate (APR) applies to loans or credit cards and includes both interest and fees.

  • For savings accounts, APY is more useful than the simple interest rate because it shows the real earning potential.

  • APY is the standard way to compare savings products since it factors in how often interest is compounded.

The power of compounding: How your money grows faster

Compounding is the key driver that makes APY different from a simple interest rate. It is the process where the interest you earn is added to your principal balance. In subsequent periods, you then earn interest on the new, larger balance.

Compound interest is interest earned on both the principal amount and accumulated interest. This creates a snowball effect, allowing your savings to grow exponentially over long periods. The more frequently interest is compounded (e.g., daily vs. monthly), the higher the APY in a savings account will be compared to the simple interest rate.

The rate of compounding plays a big role in how fast your money grows—this is reflected directly in the APY in a savings account.

Imagine earning $10 in interest in the first period. With compounding, that $10 is added to your balance, and in the next period, you earn interest on your original deposit plus that $10. This cycle repeats, leading to faster overall growth compared to earning interest only on the initial principal. This growth is reflected accurately in the APY.

Why does APY matter for your savings

APY matters because it directly impacts how much money your savings account actually earns. A small change in the APY on a savings account can lead to large differences in your total earnings over months and years. For landlords saving for significant expenses or future investments, maximizing earnings is crucial.

Consider funds you might hold in reserve for capital expenditures or property improvements. Keeping these funds in a savings account with a competitive APY ensures they are working hard for you, rather than sitting idle. Over time, the compounded earnings can help offset costs or contribute towards your next property acquisition.

A $10,000 deposit at 0.45% APY earns about $45 in interest in one year. The same deposit at 5.00% APY could earn over $500 in one year. This demonstrates the tangible impact of APY on your bottom line, especially when saving larger amounts or for longer durations.

What is a good APY for a savings account today

What counts as a “good” APY savings account rate depends on current market conditions, which tend to shift with Federal Reserve changes. Generally, a good APY is one that significantly outpaces the national average offered by traditional banks. High-Yield Savings Accounts (HYSAs) are known for offering rates well above this average.

As of early 2025, the national average APY for a savings account at traditional banks is around 0.45%. However, high-yield online accounts can offer 4% to over 5% APY during the same period. This vast difference in APY on a savings account highlights the importance of shopping around.

A good APY allows your money to maintain its purchasing power against inflation, or even grow beyond it. Comparing offers from different institutions helps you find the best APY for a savings account and maximize your earning potential.

How to find savings accounts with competitive APYs

Finding savings accounts with competitive APYs often involves looking beyond traditional brick-and-mortar banks. Online banks frequently offer higher APYs. Online banks can offer higher APYs due to lower overhead costs compared to physical branches.

HYSAs are specifically designed to offer above-average APYs. These accounts are commonly available through online-only financial institutions. When searching for an account, compare the advertised APY across multiple providers.

Beyond APY, consider other factors like minimum deposit requirements, monthly fees, and ease of access to your funds.

Calculating your potential earnings: Examples of APY in action

Seeing concrete examples helps illustrate the impact of APY on your savings growth. Let's look at how a $10,000 deposit might grow over time at different APYs. 

Consider three scenarios: an average traditional savings account (0.45% APY), a competitive high-yield savings account (4.00% APY), and a top-tier high-yield savings account (5.00% APY). Interest is assumed to compound monthly for this illustration. While the calculation uses monthly compounding to show growth increments, the APY for a savings account reflects the annual return.

Initial Deposit APY Interest Earned Year 1 Account Balance End of Year 1 Interest Earned Year 5 Account Balance End of Year 5
$10,000 0.45% ~$45 ~$10,045 ~$227 ~$10,227
$10,000 4.00% ~$408 ~$10,408 ~$2,166 ~$12,166
$10,000 5.00% ~$512 ~$10,512 ~$2,763 ~$12,763

This table shows how a higher APY can impact your total balance over time. 

After just five years, the account earning 5.00% APY has accumulated nearly $2,500 more in interest than the account earning the national average. For landlords managing larger sums, the difference can be even more substantial.

This is why prioritizing APY when choosing a savings account for rental property funds is critical. It directly contributes to the health and growth of your real estate business finances. Consider how this applies to setting aside funds for vacancies, repairs, or future down payments.

FAQs

1. What is the difference between APY and APR?

APY (Annual Percentage Yield) includes the effect of compound interest on deposits, showing total earnings. APR (Annual Percentage Rate) typically applies to loans and represents the annual cost of borrowing, often including fees.

2. Is APY paid monthly or annually?

APY represents the annual rate of return, but interest is usually calculated and compounded more frequently, often daily or monthly. The compounded interest is then added to your balance based on the account's specific schedule.

3. What is a high yield savings account?

A High-Yield Savings Account (HYSA) is a type of savings account that typically offers a significantly higher APY than traditional savings accounts. These are often provided by online banks.

4. How does a savings account APY affect rental property finances?

A higher APY on your rental property savings accounts helps grow funds set aside for reserves, capital expenditures, or future investments faster. This contributes to the overall financial health and growth potential of your real estate business. Consider organizing funds for different properties or purposes using separate accounts.

5. Why do online banks often have higher APYs?

Online banks typically have lower operating costs than traditional banks with physical branches. They can pass these savings on to customers in the form of higher APYs on savings products.
