Example Calculation
Let’s understand how it works with a simple example:
- Annual Income: $60,000
- Monthly Debt: $500
- Down Payment: $20,000
- Interest Rate: 6%
- Loan Term: 30 years
Results:

- Maximum Loan Amount: ~$150,000
- Maximum Home Price: ~$170,000
This gives you a clear idea of what you can afford before contacting lenders.
How the Calculator Works
The calculator uses a standard affordability rule:
- 28% Rule: No more than 28% of your monthly income should go toward housing
- It subtracts your existing debts from this amount
- Then calculates how much loan you can afford based on interest and loan term
This ensures your estimated payments stay within a safe financial range.
Key Factors That Affect Preapproval
Several factors influence your results:
1. Income
Higher income increases your borrowing capacity.
2. Debt-to-Income Ratio (DTI)
Lower debt improves your chances of approval.
3. Interest Rate
Higher rates reduce affordability.
4. Loan Term
Longer terms lower monthly payments but increase total interest.
5. Down Payment
A larger down payment reduces the loan amount and improves approval chances.
Tips to Improve Your Preapproval Amount
If your estimated amount is lower than expected, try these strategies:
- Pay off existing debts
- Increase your income (side jobs, bonuses)
- Save for a larger down payment
- Improve your credit score
- Choose a longer loan term
These changes can significantly boost your borrowing power.
