Mortgage Loan Qualification Calculator

Introduction: The Mortgage Loan Qualification Calculator is a valuable tool for individuals looking to assess their eligibility for a mortgage loan. By inputting key financial details such as monthly income, monthly debt payments, loan term, and interest rate, users can estimate the mortgage loan amount they may qualify for.

Formula: The calculator considers two key ratios to determine loan qualification:

  1. Front-end ratio: Monthly mortgage payment should not exceed 28% of gross monthly income.
  2. Back-end ratio: Total debt payments (including the mortgage) should not exceed 36% of gross monthly income.

If the front-end ratio is met and the back-end ratio is not exceeded, the calculator estimates the qualifying loan amount. Otherwise, it indicates that the user is not qualified.

How to Use:

  1. Enter your monthly income.
  2. Input your monthly debt payments.
  3. Specify the loan term in years.
  4. Enter the interest rate offered.
  5. Click the “Calculate” button to obtain an estimate of the qualifying mortgage loan amount.

Example: Suppose you have a monthly income of $5,000, monthly debt payments of $1,200, a loan term of 30 years, and an interest rate of 4%. After clicking “Calculate,” the result will display the estimated qualifying mortgage loan amount.
