Frequently asked questions
What formula does this use?
A = P x (1 + r/n) raised to (n x t). P is your starting amount, r the annual rate as a decimal, n how many times interest compounds per year, and t the years. It is the standard formula banks use.
Does more frequent compounding matter?
Yes. Switch between yearly, quarterly, monthly and daily and watch the chart move. Monthly compounding beats yearly by a visible margin over 10 years.
Why does the chart curve upward?
That curve is compounding itself: each year you earn interest on a bigger balance, so growth accelerates. The dashed line is your original principal for comparison.
