Calculate Annual Percentage Yield (APY), convert APR to APY, estimate compound interest, future investment value and understand how different compounding frequencies affect your savings and investments.
Provide your initial deposit, optional monthly contribution, APR, investment period and preferred compounding frequency.
The calculator converts APR into APY based on your selected compounding frequency and estimates compound growth over time.
Instantly see your APY, future value, total contributions, interest earned and effective annual return.
APY = (1 + APR / n)n − 1
Where APR is the annual percentage rate and n is the number of compounding periods per year. More frequent compounding generally results in a higher APY.
Annual Percentage Yield (APY) represents the actual annual return on an investment or savings account after accounting for compound interest. Unlike APR, APY reflects how frequently interest is compounded, making it a better measure for comparing savings and investment products.
APY includes the effect of compound interest, giving a more accurate picture of your yearly earnings than APR alone.
Banks and investment providers often advertise APY because it reflects the effective annual return after compounding.
APY = (1 + APR ÷ n)n − 1
Where APR is the Annual Percentage Rate and n represents the number of compounding periods in one year.
Future Value Formula
FV = P × (1 + APR ÷ n)n × t
| Feature | APR | APY |
|---|---|---|
| Meaning | Nominal Interest Rate | Effective Annual Yield |
| Compound Interest | Not Included | Included |
| Purpose | Borrowing & Lending Rate | Investment Return |
| Higher Value | Usually Lower | Usually Higher |
The more frequently interest is compounded, the higher your effective annual yield becomes. Daily compounding generally produces a slightly higher APY than monthly or yearly compounding for the same APR.
Suppose you invest ₹100,000 at an APR of 8% with monthly compounding for 10 years.
The APY Calculator helps estimate the Annual Percentage Yield (APY) of your savings or investment by considering both the annual interest rate (APR) and the compounding frequency. It also projects future value, interest earned and total investment growth over your chosen investment period.
Whether you're comparing savings accounts, fixed deposits, certificates of deposit (CDs) or long-term investment products, APY provides a more accurate measure of your actual annual return than APR alone.
This APY Calculator provides estimated values based on the information you enter. Actual earnings may differ because of changing interest rates, fees, taxes, account rules and other financial factors. The calculator is intended for educational and planning purposes only and should not be considered financial advice.
APY (Annual Percentage Yield) measures the effective annual return on savings or investments after considering compound interest.
APR is the stated annual interest rate, while APY includes the effect of compounding, making it a better indicator of actual yearly earnings.
Because APY accounts for compound interest. The more frequently interest is compounded, the higher the APY becomes compared to the APR.
Yes. Daily or monthly compounding generally produces a higher APY than yearly compounding when the APR remains the same.
Yes. APY is one of the best ways to compare savings accounts, fixed deposits and other interest-bearing financial products.
Yes. You can optionally include monthly contributions to estimate future savings growth more accurately.
Not always. Some financial products have variable interest rates, so the APY may change over time.
Yes. This APY Calculator is completely free and works on desktop, tablet and mobile devices.
