How to Calculate APY

Enter Nominal Rate

Input stated annual interest rate (without compounding effect).

2
Select Compounding Frequency

Choose daily, monthly, quarterly, semi-annually, or annually.

3
Get APY Result

See true annual yield accounting for compounding effect.

APY Formula:
APY = (1 + r/n)^n - 1

Where:
r = Nominal annual interest rate (decimal)
n = Number of compounding periods per year

Example: 6% compounded monthly:
APY = (1 + 0.06/12)^12 - 1 = 6.17%

Compounding Frequency Impact

Nominal Rate Annually (n=1) Semi-Annual (n=2) Quarterly (n=4) Monthly (n=12) Daily (n=365)
5% 5.00% 5.06% 5.09% 5.12% 5.13%
6% 6.00% 6.09% 6.14% 6.17% 6.18%
7% 7.00% 7.12% 7.19% 7.23% 7.25%
8% 8.00% 8.16% 8.24% 8.30% 8.33%

Note: More frequent compounding = Higher APY. Daily compounding gives maximum practical yield.

Frequently Asked Questions

Key distinction:

  • APY (Annual Percentage Yield): Includes compounding effect - what you EARN on investments
  • APR (Annual Percentage Rate): Excludes compounding - what you PAY on loans
  • Example: 6% nominal rate, monthly compounding
  • APY: 6.17% (actual return you earn)
  • APR: 6.00% (stated rate without compounding)
  • For Savers: APY is higher than APR (good!)
  • For Borrowers: APR is lower than APY (misleading!)

True return revelation:

  • Apples-to-Apples: Compare investments with different compounding fairly
  • Reality Check: Advertised "6% return" is actually 6.17% with monthly compounding
  • Long-term Impact: Over 20 years, 6% vs 6.17% = ₹3.32L vs ₹3.44L on ₹1L investment (₹12K difference!)
  • Informed Decisions: Choose higher APY, not just higher nominal rate
