what is the forumal for compound interest?

Question

anonymous · Answer

P is the principal (the money you start with, your first deposit)
r is the annual rate of interest as a decimal (5% means r = 0.05)

n is the number of years you leave it on deposit

A is how much money you've accumulated after n years, including interest.

If the interest is compounded once a year:

A = P(1 + r)n

If the interest is compounded q times a year:

A = P(1 + r/q)nq
