Frequently asked questions
What is compound interest?
Compound interest is interest earned on both your initial principal and on the accumulated interest from previous compounding periods.
How does compounding frequency affect total returns?
More frequent compounding (such as monthly vs annually) results in slightly higher total returns because interest begins earning interest sooner.
What formula is used for compound interest?
The calculator uses the standard compound interest formula: A = P * (1 + r/n)**(n*t), where P is principal, r is annual rate, n is compounding frequency, and t is time in years.
