This chart will help you calculate your monthly
principal and interest payments for both fixed and adjustable
rate loans at various interest rates over 15 and 30 year terms.
Start by finding the appropriate interest rate,
and then look across to the column indicating the desired term
of the loan. That number is the interest rate factor. This is
the dollar amount required each month to amortize $1,000 over
the specified term. To calculate your principal and interest payment,
multiply the interest rate factor by the total loan amount in
$1,000s.
Here’s an example: Interest rate: 8%
Term: 30 years
Factor per $1,000: 7.34
Total mortgage: $152,600
7.34 X 152.6 = $1,120
This is a calculation of principal and interest
only. It does not include property taxes, insurance, association
dues, or other charges.
