How the Income Mortgage Calculator Determines Affordability
The tool uses a Debt-to-Income (DTI) ratio method — a key metric lenders use to decide how much you can borrow.
Typical DTI limits:
- Conventional loans: ≤ 43%
- FHA loans: ≤ 50%
- VA loans: ≤ 41%
Formula: Maximum Mortgage Payment=Income×(DTI Limit)−Other Debts\text{Maximum Mortgage Payment} = \text{Income} \times (\text{DTI Limit}) – \text{Other Debts}Maximum Mortgage Payment=Income×(DTI Limit)−Other Debts
Then, using your loan term and interest rate, it estimates the loan principal that fits within that payment.
Pro Tips for Accurate Results
✅ Use gross (before-tax) income for accurate calculations.
✅ Keep your DTI ratio below 43% for best approval odds.
✅ Try multiple interest rates to see how they affect your maximum home price.
✅ Increase your down payment to reduce your loan amount and monthly payments.
✅ Include all monthly obligations to avoid overestimation.
