In order to calculate the monthly payment, we can rely on a relatively simple equation. The monthly payment equation can be represented as follows: M=Pr(1+r)n(1+r)n−1{\displaystyle M=P{\frac {r(1+r)^{n}}{(1+r)^{n}-1}}}. These variables represent the following inputs:  M is your monthly payment. P is your principal. r is your monthly interest rate, calculated by dividing your annual interest rate by 12. n is your number of payments (the number of months you will be paying the loan) You will need to input your principal, monthly interest rate, and number of payments in order to find your monthly payment. This information can be easily found in your loan agreement or from a quoted loan estimate. Check the information again to be sure of its accuracy before using it in calculations.  For example, imagine you have a $100,000 mortgage loan with 6 percent annual interest over 15 years. Your input for "P" would be $100,000. For "r," you would use your monthly interest rate, which would be 0.06 (6 percent) divided by 12, or 0.005 (0.5 percent). For "n" you would use your total number of payments, one for each month in fifteen years, which would be 12*15, or 180. In this example, your complete equation would look like this:M=$100,0000.005(1+0.005)180(1+0.005)180−1{\displaystyle M=\$100,000{\frac {0.005(1+0.005)^{180}}{(1+0.005)^{180}-1}}} " Simplify your terms by doing the first step in the order of operations, which is adding the 1 and "r" inside the parentheses on the top and bottom of the equation. This is a simple step that will make your equation look much less complicated. After this step, your sample equation would look like this:M=$100,0000.005(1.005)180(1.005)180−1{\displaystyle M=\$100,000{\frac {0.005(1.005)^{180}}{(1.005)^{180}-1}}} The results inside the parentheses, (1+ r), from the previous step must now be raised to the power of "n." Again, this "n" represents the total number of payments. This step requires a calculator with an exponent function, which is usually represented like this: xy{\displaystyle...
