# How do you calculate fha monthly mortgage insurance

How do you calculate fha monthly mortgage insurance

The formula for calculating the monthly mortgage insurance premium became effective May 1, 1998 (see attached Mortgagee Letter 98-22).

Below is the monthly mortgage insurance premium (mip) calculation with examples and pseudocode using the current initial and annual mip rates for mortgages assigned an fha case number prior to 4 October 2010. See FHA Single Family Home Policy Manual 4000.1 Exhibit 1.0 Mortgage Insurance Premiums [pdf] for current upfront and annual mip rates.

### calculation of the annual average outstanding balance

To start, use the original loan amount as the previous balance. repeat the following steps for the remaining months of the year (11 iterations). the computation of the following years is the same. the second year will start with the last result of the first year.

1. multiply the previous balance by the annual interest rate of the contract. round the result to two (2) decimal places based on the value in the third decimal place.

2. Divide the result by 1200. Round the result to two (2) decimal places based on the value in 3rd decimal place.

4. subtract p&i payment. note: for an arm, use original interest rate and original p&i for all years. for gem/gpm calculate the current p&i based on the amortization schedule. see the table below.

when calculating the last year, add the 12 results from that year and divide the total by 12.

the new monthly p&i for gem/gpm is not calculated if the twelfth month of the case has not been reached or if the payment number is greater than the maximum number of months.

*based on the original amortization schedule.
