Frequently asked questions
What is the compound interest formula?
A = P × (1 + r/n)^(n × t), where P is the principal, r the yearly rate as a decimal, n the number of compounding periods a year and t the years. Interest = A − P.
Why does compound interest earn more than simple interest?
Each period’s interest is added to the balance, so later interest is earned on earlier interest as well as on the principal.
