Question 543690: Can someone explain each step involved in figuring compound interest quarterly?
I understand what each letter stands for and can plug the numbers into the formula. My problem comes when you get to the nt exponent. I do not understand that part of the problem.
For example: If you have $1500 earning 4.3% interest compounded quarterly, how much money will be there in 7 years?

If you have $1500 earning 4.3% interest compounded quarterly, how much money will be there in 7 years?
------------------
A(t) = P(1+(r/n))^(nt)
---
Note: n*t is the number of times you are going to compound the money.
--------------------
Your Problem:
A(17) = 1500(1+(0.043/12))^(12*17)
---
A(17) = 1500(1.00358)^(204)
---
Note: 0.00358 is the interest rate per month.
---
A(17) = 1500*2.0730
----
A(17) = $3109.56
