How the payment is worked out

Here is the formula in plain words. The payment equals the loan times the monthly rate over one minus a discount factor. The discount factor is one divided by one plus the monthly rate, multiplied out 120 times. With 5 percent a year the monthly rate is 0.4167 percent. The loan here is $450,000.

Questions about this calculator

Is 10 years the right length for a $450,000 mortgage?

It depends on the monthly payment you can carry. At 5 percent this term costs $4,772.95 a month. A 30-year term would cost $2,415.70 a month and $419,651 in interest, compared with $122,754 over 10 years.

Does the $4,772.95 payment cover property tax and insurance?

No. The $4,772.95 covers principal and interest only. Tax, insurance and any mortgage insurance would sit on top of it.

Is it better to put extra money toward a $450,000 mortgage over 10 years or save it elsewhere?

The calculator can only show what extra payments do. On this loan an extra $480 a month saves $14,964 of interest and ends the loan 1 year 1 month sooner. Whether that beats saving or investing the money depends on your other goals and on what you could earn elsewhere.

What if the rate on a $450,000 mortgage over 10 years were one point higher?

The payment would rise from $4,772.95 to $4,995.92, which is $222.97 more each month. One point lower would give $4,556.03.
