How the payment is worked out
A level payment loan has a neat rule behind it. Each month the interest is the balance times 0.4167 percent. The payment is set so that after 120 months the balance lands exactly at zero. Solving for it on $400,000 gives the loan times the monthly rate, divided by one minus one over one plus the monthly rate raised to the power of 120.

After 5 years of payments you would still owe $224,819. Total interest over the whole loan is $109,114.
