It depends on how many points you buy and how long the loan is for.
Here is a website for a loan calculator that will give you monthly payments after you input amount, interest rate, and the length of the loan.

Your loan amount will obviously vary depending on how many points and price/point.
The interest rate is generally 9.75%, or 10.75% if you don't use an automatic payment.
Loan lengths are up to 10 years but can be paid off early without penalty.
Then the annual maintenance fees ($3.83/point for SSR) can be setup on a monthly basis also.
