$600,000 Mortgage Over 30 Years
A 30-year mortgage of $600,000 means 360 equal payments. Start with a rate of 6.25 percent and adjust it as you like.
That makes $3,694.30 a month at the start. The interest over the whole loan comes to $729,949.
How the payment is worked out
Lenders use the standard loan formula. The yearly rate of 6.25 percent becomes a monthly rate of 0.5208 percent. The term of 30 years becomes 360 payments. The payment is the loan of $600,000 times the monthly rate, divided by one minus one over the growth factor, where the growth factor is one plus the monthly rate, multiplied by itself 360 times.
Worked example
Say you borrow $600,000 at 6.25 percent for 30 years. The payment is $3,694.30 a month. In month one, $3,125.00 pays interest and $569.30 reduces the balance.
Part of the way through, after 15 years, the balance is still $430,861. That is 72 percent of the original loan. Early payments mostly cover interest.
