What do the 28% and 36% thresholds represent in the calculator?

The 28% front-end ratio limits housing expenses to that percentage of gross monthly income, while the 36% back-end ratio includes all debt obligations; staying within both thresholds is typically preferred by lenders for mortgage approval.

Can I use this calculator if I have irregular income?

The tool requires gross monthly income as input; individuals with variable earnings should use an average monthly figure or consult with a lender about income verification methods.

Does the calculator include down payment amount in its analysis?

No, the 28/36 rule calculator focuses on debt-to-income ratios based on income, debts, and housing costs; down payment size affects loan-to-value ratio but is not part of this specific calculation.

How accurate are the results for different loan types?

The calculator provides a general framework based on standard lending guidelines; specific loan programs (FHA, VA, conventional) may have different debt-to-income ratio requirements that are not reflected in these results.
