Variables: Gross Monthly Income: Your total income before taxes and deductions. Total Monthly Debt Payments: Sum of all recurring monthly debt obligations like car loans, student loans, and credit card minimums. MIN: Represents the minimum value between the two calculated figures.
Worked Example: Assume a gross monthly income of $7,000 and total monthly debt payments of $800. First, calculate 28% of income: 0.28 * $7,000 = $1,960. Then, calculate 36% of income minus debts: (0.36 * $7,000) - $800 = $2,520 - $800 = $1,720. Then, the maximum monthly housing payment is the lesser of these two, which is $1,720.
This calculator's methodology is based on widely accepted lending guidelines, specifically the 28/36 rule, which is a common standard used by mortgage lenders to assess borrower capacity. These ratios are frequently referenced by financial institutions and regulatory bodies like the Consumer Financial Protection Bureau (CFPB) in evaluating mortgage eligibility.
