This FHA loan calculator is very accurate:
You can go to that site and play with the loan amounts, interest rates, etc. and it will give you the various fees including the monthly MIP.
I have an excellent FHA lender that I've worked with for several years; if you'd like her contact info, just send me a quick email.
Thanks for the question!
