Estimate Your Home Loan Approval
Enter your income, debt, and estimated housing costs to see a quick approval estimate based on debt-to-income (DTI) rules commonly used by lenders.
What this home loan approval calculator does
This calculator gives you a practical estimate of how much mortgage you may qualify for by using your gross income, monthly debts, loan terms, and a lender-style debt-to-income (DTI) limit. It is built to answer two common questions quickly:
- How large of a home loan might I be approved for?
- Is my target home price realistic based on my current finances?
How the estimate is calculated
1) Gross monthly income
We add borrower and co-borrower annual income, then divide by 12. This is your gross monthly income before taxes.
2) Maximum monthly debt allowed
Lenders commonly cap your total monthly obligations at a DTI threshold (often around 36% to 45%, depending on loan type). The calculator multiplies your gross monthly income by your selected DTI cap.
3) Housing payment budget
We subtract your current monthly debts (car loans, student loans, credit cards, personal loans, etc.) from your maximum allowed debt. The remaining amount is your housing budget.
4) Mortgage principal estimate
From your housing budget, we subtract estimated taxes, insurance, and HOA dues. The remaining amount is used for principal and interest, then converted into an estimated maximum loan amount using standard mortgage amortization math.
Understanding the inputs
- Annual Gross Income: Use pre-tax income documented by pay stubs/W-2/returns.
- Monthly Debt Payments: Include minimum required debt payments shown on your credit report.
- Max DTI Ratio: Conventional underwriting often targets up to 43%, but approvals vary.
- Taxes + Insurance + HOA: Don’t ignore these—high carrying costs can reduce approval power significantly.
- Interest Rate: Higher rates lower your borrowing power, even with the same income.
Ways to improve your approval amount
- Pay down revolving debt to lower monthly obligations and improve DTI.
- Increase your down payment to reduce the loan amount needed.
- Shop interest rates across multiple lenders.
- Avoid new debt before applying for a mortgage.
- Include stable co-borrower income if appropriate.
Important limitations
This is an educational estimate, not a formal loan commitment. Real approvals also depend on credit score, employment history, reserves, property type, loan program rules, and lender overlays. Use this tool to prepare, then confirm with a licensed lender.
Quick FAQ
What DTI should I use?
Start with 43% for a realistic baseline. If your credit is strong and loan program allows it, some approvals may be possible above that.
Does this include PMI?
Not directly. If you plan to put less than 20% down, add an estimated PMI amount into the monthly taxes/insurance/HOA field for better accuracy.
Is gross or net income used?
Most mortgage qualification models use gross income, which is why this calculator does too.
