Annual Percent Yield Calculator

The term “power of compounding” is familiar for investment enthusiasts. It is the way to make our hard-earned money work hard for us to bring in exponential gains over the long term. Annual Percent Yield is one of the metrics one must understand to decode the power of compounding.

Join us on our online Annual Percent Yield Calculator page as we demystify the power of compounding. We explain how to calculate annual percent yield along with how money works in compound interest.

What is the Annual Percent Yield(APY)?

Annual Percent Yield, also termed as ‘annual interest yield' or the ‘effective annual rate is the actual interest you would earn if your investment were to be compounded.

The difference between simple interest and annual percent interest is:

  • Simple interest is calculated on the amount of the investment for a given tenure.
  • Annual Percent Yield is calculated on the amount of the investment plus the interest it makes in a given tenure.

The formula for calculating Annual Percent Yield is A = I(1 + r/n)n*y -1.

The final amount that you would receive invested in the APY plan would be: A = I(1 + r/n)n*y


A = Final amount
I = Initial Investment
r = period rate
n = number of compounding periods per year (for ex: n=2, if compounding interest is half-yearly)
y = tenure in years

Annual Percent Yield

Let us understand APY calculation with an example:

Say you want to invest $2,000. You can choose to put it in simple interest or compound interest as per the investment plans your bank offers.

Assume the interest is 6% - for both the plans with simple interest and compound interest.

Now, the plan that works on simple interest will give you $2120 at the end of one year.

The plan with compound interest will give you $2,123.36 at the end of the year, compounded monthly.

If the difference seems small for one year, let us understand the power of compounding in the long run.

The same $2000 will give $3200 after 10 years on simple interest, while you get $3638.79 on the same investment compounded monthly for 10 years.

Well, isn’t the difference clear? You can calculate the APY using our online APY calculator and make fruitful investment decisions.

FAQs about APY

I have heard the term APR. Are APR and APY both same?

Both are different. APR stands for Annual Percentage Rate. It implies the interest you would pay when you take a loan such as an educational loan, housing loan, etc. It impacts your credit score too.

On the other hand, APY stands for Annual Percent Yield and tells you how your money can grow over time by leveraging the power of compounding. APY indicates how much banks would add to your investment at the end of the tenure.

What factors should I consider when investing in an APY plan?

Various factors given below can impact APY. Choose the best APY plan by consulting your financial advisor.

  • Nature of the bank: Online or Traditional
  • Membership with the parent bank/union.
  • The type of account
  • The nature of the account – flat or tiered
  • Amount of the investment
  • Savings balance
  • Nature of interest – temporary or permanent

What is a blended APY?

Blended APYs vary from bank to bank. In blended APYs, the rate of interest varies with the slab.

For instance, if the APY is 5% till $15000, and 6% over $15000.

Say you invested $16000. Some banks calculate APY for the whole $16000 as 5% for the first $15000 and then 6% for the remaining $1000.

In case their blended APY is 4.5%, then the calculation is done at the rate of 4.5%, over the whole $16000.

To avoid confusion while choosing such blended plans to make the right pick, in addition to your financial advisor’s guidance, our online APY calculator comes in handy.
