When choosing a bank, do you pay close attention to its interest rates? While they seem to barely make any difference, interest rates are not insignificant at all—they're a crucial part of banking, whether you're saving or borrowing money.

To make the most of your savings, it's important to understand how bank interest rates work.

Here's everything you need to know about the interest rate on savings accounts, including why you should go for a high-yielding account.

What is the Meaning of Interest Rate on a Savings Account?

An interest rate is the percentage of your savings that determines how much the bank pays you to keep your money on deposit.

When you deposit money in your savings account, you're lending it to the bank. Your funds are then invested through loans, credit cards, and other financial products. In return, you earn interest on your savings.

How to Compute Bank Interest Rates on Savings

Generally, banks use the principle of compound interest[1] based on the amount saved and all accumulated interest.

Simply put, you're paid interest on top of the interest you earned previously.

To know how bank interest rates work, here's the general formula for a savings account interest computation:

A = P x (1 + R ÷ n)n


  • A = Amount of money in the savings account after interest is paid
  • P = The principal or original account balance
  • R = Interest rate in decimal format (e.g., 0.25% = 0.0025)
  • n = Number of times the bank calculates interest in a year (e.g., interest calculated daily = 365 time periods)

To compute the net interest, you also have to deduct the 20% final withholding tax (as mandated by the Bureau of Internal Revenue).

Hate crunching numbers? Use an online savings calculator to quickly compute your interest. Calculators.org[2] is a good calculator to use, as it includes the tax rate and inflation rate in its computation (However, it calculates only interest compounded monthly).

Simply plug in the required information and hit the calculate button, and the online calculator will instantly show the results.

3 Key Benefits of High-Interest Savings Accounts

With the typically low savings deposit rates, you might wonder: do bank interest rates really matter?

Of course, they do. Interest rates are a critical consideration when choosing a savings account. Your interest rate has an impact on how much your savings will grow over time. If it's too low, you'll hardly earn anything or even lose some money.

Conversely, a high-interest rate offers several advantages that can help you achieve your financial goals.

1. Higher Earning Potential Than Traditional Accounts

Regular savings accounts generally earn very little interest. Over the past five years, average bank interest rates have ranged only from 0.685% to 1.231% annually, based on Bangko Sentral ng Pilipinas (BSP) data[3].

While low-earning savings accounts are considered the norm, a few bank accounts offer higher-than-average rates.

Banks like ING Philippines that offer high-yield savings accounts have interest rates as high as 4% per year, allowing depositors to grow their money much faster. Although these bank interest rates don't earn as much as high-risk investments like stocks, they yield around eight to 40 times more than most savings accounts.

Differences in bank interest rates can add up in the long run, especially if you're keeping a large balance, depositing money regularly, and withdrawing less.

2. Protection Against Inflation

Do you keep your funds in a low-interest savings account? It's easy to lose your money to inflation that way.

Inflation—the rate at which prices of goods and services increase over time—reduces the value of money. If your interest rate is below the inflation rate, you're effectively losing money even though your savings account is earning interest.

Your best bet is a savings account with an interest rate that's higher than the average inflation rate (which is 2.6% as of April 2020)[4]. It helps you beat the effect of inflation on your savings.

3. Maximized Savings for an Emergency or Large Purchase

Putting your money in a high-yield savings account (like those from ING Philippines, CIMB, among many others) is a great way to save for a rainy day or a big purchase like a car or house. Unlike stock investing, you won't lose the value of your money in a high-interest savings account.

With a high interest rate, you can maximize your savings while being able to withdraw cash when you need it. It's extremely helpful, especially during the COVID-19 crisis when job loss, business closure, illness, or any emergency can seriously affect your finances.

5 Reasons to Open a High-Yield Savings Account with ING Philippines

Bank Interest Rates - ING Savings Account

Online savings accounts, with their high-interest rates, are among the best places to put your savings, according to financial experts. While the concept of all-digital banking is relatively new in the Philippines, it offers real advantages over traditional banking.

Here are the things you can achieve with an ING savings account.

1. Save More and Faster

ING Philippines offers a 4% interest rate annually on your savings until July 31, 2020. It's currently among the highest deposit rates in the Philippines.

The online bank calculates interest daily based on the average daily balance using this formula:

(Available end of day balance x interest rate) x (1 day ÷ 365 days)

This means your savings increase every day by another 1/365th of 4% of your balance. Because interest is added more frequently to your balance (daily versus monthly and annually), you can grow your funds faster with an ING Savings Account, thanks to the power of compound interest.

To illustrate, here’s a comparison between a regular savings account and an ING Savings Account:

Regular Savings Account
PHP 20,000 x 0.25% = PHP 50
PHP 50 – 20% (tax) = PHP 40 per year

ING Savings Account
PHP 20,000 x 4% = PHP 800
PHP 800 – 20% (tax) = PHP 640 per year

2. Start Saving Easily

Regular savings accounts of most local banks require large amounts (usually PHP 2,000 to PHP 3,000) for the initial deposit and maintaining balance. To earn interest, you have to maintain an even larger amount in your account.

That isn't the case with an ING Savings Account. There are no required minimum opening, maintaining, and interest-earning balances. You can open an online savings account regardless of how much you can afford to save.

As a fully digital bank, ING Philippines operates without physical branches and bank tellers, passing on the savings to clients by not charging any fees. For example, you can transfer money from your ING Savings Account to accounts with other banks for free.

Such flexibility is very useful for urgent transactions, like sending money to a loved one for medical bills or paying for essential goods.
