Based on this information, it calculates:
- Maximum monthly mortgage payment
- Available amount for principal and interest

Understanding Key Mortgage Ratios
🔹 Front-End Ratio (Housing Ratio)
This measures how much of your income goes toward housing expenses.
- Ideal: ≤ 28%
🔹 Back-End Ratio (DTI)
This includes all debts plus housing costs.
- Ideal: ≤ 36%
- Acceptable: ≤ 43%
Lenders use these ratios to determine your risk level.
How the Calculator Works
The calculator uses standard lending guidelines:
1. Front-End Limit
Maximum housing cost = 28% of monthly income
2. Back-End Limit
Total debt (including mortgage) = 43% of income
3. Final Monthly Payment
The lower value between front-end and back-end limits is used.
4. Available Loan Payment
Subtract housing expenses (tax, insurance, HOA) to find what’s left for principal and interest.
