O que é um Compound Interest Calculadora?
A Compound Interest Calculator shows how your investment grows over time when interest is earned on both the principal and accumulated interest. It's a powerful tool for understanding long-term investment growth and the time value of money.
Como usar
Enter your initial investment amount, annual interest rate, compounding frequency (monthly, quarterly, annually), time period, and any regular contributions. The calculator will show your final balance and total interest earned.
Perguntas frequentes
What is compound interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. Essentially, it means earning 'interest on interest,' which causes your wealth to grow at a faster rate compared to simple interest.
How is compound interest calculated?
The formula used is A = P(1 + r/n)^(nt), where 'A' is the future value, 'P' is the principal investment amount, 'r' is the annual interest rate (decimal), 'n' is the number of times interest is compounded per year, and 't' is the time in years.
What is the difference between simple interest and compound interest?
Simple interest is calculated only on the original principal (the amount of money you initially deposited or borrowed). Compound interest is calculated on the principal plus any interest that has already been added to the account.
Why does the compounding frequency matter?
The frequency determines how often interest is added to the principal. The higher the frequency (e.g., daily vs. annually), the faster your investment grows because interest is calculated on a more regularly increasing balance.
Can I include monthly contributions in this calculation?
Yes, this calculator supports recurring deposits. By entering a monthly contribution amount, you can see how regular savings combined with compound interest accelerate your investment growth over time.
What is the 'Principal' amount?
The principal is the initial sum of money you are investing or saving. It is the starting balance before any interest or additional contributions are applied.
