Compound interest is mathematically calculated using standardized formulas that account for initial principal, compounding frequency, and regular additions.
Used to calculate growth on a lump-sum investment without any ongoing contributions.
A = P (1 + r / n)n * t
Used when regular, recurring deposits (monthly or yearly) are made to the account.
A = P(1 + r/n)nt + PMT [ ((1 + r/n)nt - 1) / (r/n) ]

Compound interest allows your earnings to generate additional earnings over time. Unlike simple interest, returns are calculated on both the original investment and previously accumulated interest, accelerating long-term growth.
The longer your money remains invested, the greater the impact of compounding. Even modest investments can grow significantly when given enough time, making early investing one of the most effective wealth-building strategies.
Adding money consistently to an investment account increases the principal available for compounding. Small monthly contributions can dramatically increase the final value of an investment over many years.
Interest can be compounded annually, quarterly, monthly, or daily. More frequent compounding generally results in slightly higher returns because interest is added to the balance and begins earning additional interest sooner.
Compound interest is interest earned on both the original principal amount and any previously accumulated interest. This allows investments and savings to grow faster over time compared to simple interest.
Simple interest is calculated only on the original principal, while compound interest is calculated on both the principal and previously earned interest. As a result, compound interest generates exponential growth over time.
Compounding frequency refers to how often interest is added to the principal balance. Common frequencies include annually, semi-annually, quarterly, monthly, and daily. More frequent compounding generally results in higher returns.
The longer your money remains invested, the more time compound interest has to work. Starting early allows interest to generate additional interest for many years, significantly increasing the final investment value.
Yes. Making regular deposits or investments adds more principal to the account, allowing future interest to be calculated on a larger balance. Consistent contributions can dramatically increase long-term wealth accumulation.
