**Anonymous**, Tuesday, June 23, 2009 at 5:57pmCONTINUOUSLY: A=Pe^(rt)

(e=2.71828 18284 59045 23536…)

PERIODICALLY: A=P(1+r/n)^(nt)

P = principal amount (the initial amount you borrow or deposit)

r = annual rate of interest (as a decimal)

t = number of years the amount is deposited or borrowed for.

A = amount of money accumulated after n years, including interest.

n = number of times the interest is compounded per year

Since it's compounded continuously, use Pert (The first formula).
