Effective Annual Yield Calculation

Investment Details

Principal amount invested

Stated annual interest/dividend rate

How often dividends/interest are paid

Whether payments are reinvested

Additional Parameters

Time horizon for analysis

Tax rate on dividends/interest (0 for tax-free)

Annual management or expense fee

Expected annual inflation rate

EAY Formula

EAY = (1 + r/n)^n - 1
Where:
EAY = Effective Annual Yield
r = Nominal annual rate
n = Payment frequency
With Reinvestment: Compounds at each payment

Investment Examples

Dividend Stock
4% yield, quarterly dividends
Corporate Bond
5.5% coupon, semi-annual payments
High-Yield Savings
3.5% APY, monthly compounding

Yield Types

Nominal Yield: Stated annual rate
Current Yield: Annual income ÷ Current price
Effective Yield: True annual return with compounding
Yield to Maturity: Total return if held to maturity
After-Tax Yield: Yield after taxes

Key Considerations

✓ Reinvestment assumptions
✓ Tax implications
✓ Management fees impact
✓ Inflation effects
✓ Payment frequency benefits
✓ Risk vs. yield trade-off

Understanding Effective Annual Yield

Effective Annual Yield (EAY) represents the true annual return on an investment, accounting for the frequency of dividend or interest payments and the compounding effect of reinvestment.

  • True Return: Shows actual annual yield including compounding
  • Payment Frequency: More frequent payments can increase effective yield
  • Reinvestment Impact: Assumes dividends/interest are reinvested
  • Comparison Tool: Enables fair comparison between investments
