Perguntas Frequentes

What is Compound Interest?

It is 'interest on interest'. The yield of one month is added to the capital to yield more the next month. It is the most powerful force for building wealth in the long run.

What is the difference from Simple Interest?

In simple interest, the yield is calculated only on the initial value. In compound interest, the yield grows exponentially as it applies to the accumulated value.

When to use this calculator?

Use it to plan retirement, financial independence, or long-term goals (like buying a house in 10 years).
