Affordability Calculator

This calculator is used to determine, from a lender's point of view, the amount of money that a prospective homeowner can comfortably borrow, based on factors like such as income, existing debt, etc. This can be a very helpful and insightful tool for the borrower.

The default entries provided in the calculator show a loan of undetermined value with a 4.75% interest rate, a 30-year term and a down payment of 10%. Some of the Financial Analysis results calculated are as follows: the actual front ratio is 25%; actual back ratio is 37%; a maximum affordable home value of $328,100.00; maximum monthly debt payments of $910; the maximum loan that borrower can afford is $295,300; a monthly principal and interest (P&I) payment of $1540.80 and the down payment is $32,800.

The front ratio (or housing payment ratio) compares the total mortgage payment to monthly income; back ratio (or total debt ratio) compares the sum of all monthly debts, including mortgage payment and all other monthly obligations, to the monthly income.
