What is the fastest way to calculate compound interest?

Use the formula A=P(1+r/n)^nt. For example, say you deposit $5,000 in a savings account that earns a 3% annual interest rate, and compounds monthly. You'd calculate A = $5,000(1 + 0.03/12)^(12 x 1), and your ending balance would be $5,152. So after a year, you'd have $5,152 in savings.

How do you master compound interest?

On an annual basis you can calculate compound interest on an annual basis, like: For the second year, compound interest after using this formula would be P(1 + r/n)^(nt). Now, to find out the compound interest, you have to use CI = P (1 + r/n)nt – P by subtracting the principal amount from the compound amount.

Is there a formula for calculating compound interest?
