APYとは何ですか
年次 パーセンテージ Yield (APY) is the effective 年次 レート of リターン, accounting for compound 金利. Unlike APR which is used for loans, APY is used for investments and savings accounts. APY reflects the actual リターン on 投資 when compounding is considered, making it higher than the nominal 金利 when compounding occurs more frequently than annually.
使い方
Enter the nominal 金利 offered by the bank, select the compounding frequency (daily, 月次, quarterly, etc.), input your 元金 投資 金額, and specify the 投資 period. The 計算機 shows the APY, future 値, 合計 金利 earned, and compares different compounding scenarios.
よくある質問
What is APY?
APY stands for Annual Percentage Yield. It represents the real rate of return earned on an investment, taking into account the effect of compounding interest. Unlike simple interest, APY allows you to earn interest on your interest.
What is the difference between APY and APR?
APR (Annual Percentage Rate) is the simple interest rate charged or earned over a year, not accounting for compounding. APY includes the effect of compounding, making it generally higher than APR for investments and lower for loans when compounding occurs.
How do I use the APY Calculator?
Enter your initial principal balance, the nominal annual interest rate (as a percentage), the compounding frequency (e.g., daily, monthly, yearly), and the time period for the investment. The calculator will compute the total balance and the effective APY.
What is compounding frequency?
Compounding frequency refers to how often interest is calculated and added to your account balance. Common frequencies include Daily, Monthly, Quarterly, and Annually. The more frequently interest is compounded, the higher the total yield will be.
Can I use this calculator for crypto staking?
Yes. Many cryptocurrency exchanges and platforms list rewards as APY. You can use this calculator to estimate your earnings on staked assets, provided you know the compounding schedule and the nominal rate.
Why is my result different from the bank's quote?
Banks may advertise a nominal rate but pay out based on a specific compounding schedule. Additionally, this calculator assumes a fixed interest rate and no additional deposits or withdrawals, whereas real-world accounts may vary.
