公式
Compound interest with periodic additions. Balance grows each capitalization period by: Balance × (1 + r/n), where r is annual rate and n is periods per year. Monthly additions are added before each period's interest calculation.
常见问题
What is capitalization of interest?
Capitalization (compounding) means earned interest is added to the principal, so future interest is calculated on a larger amount. More frequent capitalization yields higher returns.
Which capitalization frequency is best?
Monthly capitalization gives the highest effective yield because interest compounds more frequently. Yearly capitalization gives the lowest.
What is the effective rate?
The effective rate is the annualized return that accounts for compounding. It is always higher than the nominal rate when interest is compounded more than once per year.
How do monthly additions affect the result?
Regular additions significantly increase the final amount through compound growth. Each addition earns its own interest for the remaining term.
