Maturity Value
Total Interest
Effective Annual Yield

How it works

Maturity Value = Principal × (1 + r/n)^(n×t). Total Interest = Maturity Value − Principal. Effective Annual Yield = (Maturity / Principal)^(1/t) − 1. We calculate based on APY and compounding frequency.

Inputs explained

Initial Deposit, Annual Interest Rate (APY), CD Term (Months or Years), Compounding Frequency.

Example

Deposit=$10,000, APY=4.5%, Term=12 months, Monthly compounding → Maturity≈$10,459; Interest≈$459; Effective Yield≈4.59%.

Tips & notes

  • Longer terms and higher rates yield more interest.
  • APY includes the effect of compounding within the year.
  • Early withdrawal usually incurs penalties; avoid if possible.

FAQs

Annual Percentage Yield (APY) reflects the rate of return, including compounding interest.

Using compound interest: Maturity = Principal × (1 + r/n)^(n×t), where r is APY, n is compounding frequency, and t is term in years.
