Discover how small, consistent investments can grow into significant wealth over time using the mathematical power of compound interest.
The Math Behind It
FV = P*(1+r/n)^(n*t) + PMT*((1+r/n)^(n*t)-1)/(r/n)The formula considers two parts: the principal (initial investment) compounding over time, and the future value of a series of monthly contributions.
Example
If you invest $10,000 today at a 7% annual return, compounded monthly, and add $500 each month for 10 years, you'll end up with approximately $106,300.
