Lenders multiply your outstanding balance by your annual interest rate but divide by 12 because you're making monthly payments. So if you owe $300,000 on your mortgage and your rate is 4%, you'll initially owe $1,000 in interest per month ($300,000 x 0.04 ÷ 12).
The formula for calculating simple interest plus principal is A = P(1 + rt). Here, A is the total accrued amount, which is principal plus interest or P + I, so A = P + I. The formula for calculating interest is I = Prt.
