Computing the Monthly Payment for Principal and Interest

Sara Wilson bought a home for $160,000. She made a $20,000 down payment. The mortgage is for 30 years and has a rate of 8%. What are the monthly payment and total cost of interest?

15-8

Step 2. Look up the rate (8%) and the term (30 years) in the amortization chart. At the intersection is the table factor. ($7.34)

Step 3. Multiply Step 1 by the factor in Step 2

$140 x $7.34 = $1,027.60

Step 1. Divide the amount of the mortgage by $1,000

$140,000 = $140 $1,000

Hidden Cost in Purchasing a Home

Closing Costs - Cost associated with the passing of property from the seller to buyer. Include: lawyer’s fees, title search, points, etc. A point is a one-time charge that is a percent of the mortgage.

Escrow Amount - A special interest bearing account in which the buyer is required to deposit 1/12 of the insurance cost and 1/12 of the real estate taxes each month

Repairs and Maintenance - The cost of keeping the property up. Includes: paint, wallpaper, landscaping, etc.

15-13

Step 2. Calculate the amount used to reduce the principal: Principal reduction = Monthly payment - Interest (Step 1.) $1,027.60-$933.33 = $94.27

Step 3. Calculate the new principal: Current principal - Reduction of principal (Step 2) = New Principal $140,000 - $94.27 = $139,905.73

Step 1. Calculate the interest for a month (use current principal): Interest = Principal x Rate x Time

$140,000 x.08 x 1/12 = $933.33

Calculating Interest, Principal, and New Balance of Monthly Payment

15-14

Step 2. Principal reduction = Monthly payment - Interest (Step 1.)

$1,027.60 - $932.70 = $94.90

Step 3. Current Principal - Reduction of principal (Step 2) = New Principal

$139,905.73 - $94.90 = $139,810.83

Step 1. Interest = Principal x Rate x Time

$139,905.73 x.08 x 1/12 = $932.70
