Example Calculation
Let’s walk through an example to understand how it works in practice.
Scenario:
- Monthly income: $6,000
- Monthly debts: $1,000
- Interest rate: 6%
- Loan term: 30 years
Step 1: The calculator first determines your available income after debts:
$6,000 - $1,000 = $5,000
Step 2: It applies a Debt-to-Income (DTI) ratio limit of 43%, meaning only 43% of your available income should go toward your mortgage payment.
$5,000 × 0.43 = $2,150 (maximum monthly payment)
Step 3: Using the interest rate and loan term, the calculator estimates how much you could borrow to keep that $2,150 monthly payment over 30 years at 6%.
The result might be an estimated loan amount of around $359,000 and a monthly mortgage payment of $2,150.
This gives you a realistic picture of what price range to look at when house hunting.
Understanding the Key Factors
1. Monthly Income
Your income determines how much you can afford. The higher your income, the larger the potential loan — but lenders also consider consistency and stability.
2. Monthly Debts
Your existing financial obligations directly affect your prequalification. Lower debts mean a higher available income for mortgage payments.
3. Interest Rate
Even a small difference in interest rate can change your loan eligibility by thousands of dollars. It’s always smart to compare rates from multiple lenders.
4. Loan Term
Longer loan terms (e.g., 30 years) reduce monthly payments but increase total interest paid. Shorter terms (e.g., 15 years) increase payments but save interest overall.
