I have a project where I'm supposed to calculate the interest of a given amount monthly and continuously, and then compare the methods. We were given a chart with each's month's principal amount (and we're given 1 number for each month of 1 year), and I want to calculate the interest for each month. In this case, what would I put as the "t" in the A=(1+(r/n))^nt formula?

1. If my initial amount were \$18.60 and my APR is 2.5%, would the formula be:

A= 18.60(1+(.025/12))^(12)(1/12)
