How to Use the Mortgage Qualifying Calculator (Step-by-Step)
Using our calculator is incredibly straightforward. Just follow these steps:
1. Enter Your Monthly Gross Income
This is your total income before taxes and other deductions. It includes salaries, bonuses, rental income, and any other sources of regular income.
Example: If you earn $75,000 per year, your gross monthly income would be approximately $6,250.
2. Enter Your Monthly Debt Payments
Include all recurring monthly debts such as:
- Credit card minimum payments
- Student loans
- Car payments
- Personal loans
- Any other fixed obligations
Do not include utilities, groceries, or other non-debt expenses.
3. Enter the Interest Rate
This is the annual mortgage interest rate offered by lenders. Make sure to use the percentage format (e.g., enter 6.5 for a 6.5% rate).
Tip: Check with your lender or use a recent mortgage rate quote online.
4. Enter the Loan Term (in Years)
Most mortgages have loan terms of 15, 20, or 30 years. Select the one you expect to use.
5. Click "Calculate"
Once all fields are completed, click the Calculate button. The calculator will instantly display:
- Maximum Monthly Mortgage Payment: How much you can afford to pay each month toward your mortgage.
- Estimated Loan Amount: The approximate loan value you qualify for based on your data.
6. Reset if Needed
Click Reset to clear all fields and start over.
Practical Example
Let’s walk through an example to illustrate how this tool works in a real-world scenario.
Scenario:
- Monthly Gross Income: $7,000
- Monthly Debt Payments: $1,000
- Interest Rate: 6%
- Loan Term: 30 years
Result:
- Maximum Monthly Mortgage: $2,010
- Estimated Loan Amount: $335,000 (approximately)
This means, with the given inputs, you may qualify for a mortgage loan of around $335,000. The actual approval will depend on lender-specific underwriting, but this gives you a powerful pre-check.
Why Debt-to-Income Ratio Matters
This calculator is based on a standard Debt-to-Income (DTI) threshold of 43%, commonly used by lenders to determine mortgage eligibility.
DTI Formula: DTI=Monthly Debt Payments + Mortgage PaymentGross Monthly Income\text{DTI} = \frac{\text{Monthly Debt Payments + Mortgage Payment}}{\text{Gross Monthly Income}}DTI=Gross Monthly IncomeMonthly Debt Payments + Mortgage Payment
Lenders prefer borrowers with a DTI ratio below 43%, as this indicates a healthy balance between income and obligations. Our calculator uses this rule to reverse-engineer how much you can safely borrow.

2. Is this calculator accurate?
It provides a close approximation using standard DTI guidelines, but your actual mortgage eligibility will depend on lender policies.
3. What is a good DTI ratio?
Most lenders prefer a DTI ratio under 43%. Lower ratios (like 36% or below) are even better.
4. Does it include taxes and insurance?
No, this tool estimates principal and interest only. Property taxes and homeowners insurance should be added separately when budgeting.

Include only fixed monthly debt payments: loans, credit cards, etc. Not utilities or groceries.

Yes. Add the combined gross monthly income and debts of all borrowers.

Higher rates reduce the loan amount you can qualify for; lower rates increase it.
9. What loan term should I choose?
Use the term you plan to apply for—15, 20, or 30 years. Longer terms mean lower monthly payments but more interest over time.
