Frequently Asked Questions & Guide
What is compound interest?
Compound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods on a deposit or loan.
How does monthly contribution affect compounding growth?
Adding regular monthly contributions significantly accelerates growth because interest is calculated on a larger base balance each month.
Does this calculator account for inflation or taxes?
No, all projections are gross figures. In reality, taxes and inflation will affect your net purchasing power over time.
