$300,000 Mortgage Over 30 Years
Here is a $300,000 mortgage laid out over 30 years. The rate starts at 6.25 percent. Change the amount, the rate or the term to see a different loan.
At the start the monthly bill is $1,847.15. All 360 payments together come to $664,975.
How the payment is worked out
Start by turning the yearly rate into a monthly one. 6.25 percent a year is 0.5208 percent a month. Next count the payments, which is 360 for 30 years. The payment is then the loan of $300,000 times the monthly rate, divided by one minus one over the growth factor. The growth factor is one plus the monthly rate multiplied by itself 360 times.

Questions about this calculator
Is 30 years the right length for a $300,000 mortgage?
It depends on the monthly payment you can carry. At 6.25 percent this term costs $1,847.15 a month. A 15-year term would cost $2,572.27 a month and $163,008 in interest, compared with $364,975 over 30 years.
Does the $1,847.15 payment cover property tax and insurance?
No. The $1,847.15 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 $300,000 mortgage over 30 years or save it elsewhere?
The calculator can only show what extra payments do. On this loan an extra $180 a month saves $90,132 of interest and ends the loan 6 years 4 months 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 $300,000 mortgage over 30 years were one point higher?
The payment would rise from $1,847.15 to $2,046.53, which is $199.38 more each month. One point lower would give $1,656.61.
