Mortgage Calculations - Fixed Monthly Payments 

Intro:

The following formula is used to calculate the fixed monthly payment, P, required to fully amortize a loan of L dollars over a term of n months at a monthly interest rate of c.  NOTE: If the quoted rate for the loan is 6%, c is calculated as 0.06/12 or .005

For more information about how this works, check out the Mortgage Professor's website.

The Formula:

P = L[c(1 + c)n] / [(1 + c)n - 1]

LEGEND:

P = Your fixed monthly payment.
L = The total loan amount in dollars.
c = The interest rate.  NOTE: If the quoted interest rate is 6%, c is calculated as (0.06 / 12) ==> 0.005
n = The term (number of months) for the loan.

Example Scenario:

Let's say your loan amount is $121,200 (L = 121,200), your interest rate is: 2.875% (c = 0.02875/12), and the term of your loan is 180 months or 15 years (L = 180), then your fixed monthly payment, P, will be: $829.72
