Understanding Your Results
Your estimated monthly mortgage payment reflects the minimum amount you will owe each month to service the loan and carry the property.
- Principal & Interest: The core loan payment based on your interest rate and loan term.
- Property Taxes: Local taxes spread across monthly payments; often underestimated by buyers.
- Insurance: A necessary operating cost that varies by location and property type.
A mortgage payment that appears affordable on paper can still strain cash flow once operating expenses and vacancies are considered.
Next step (optional):
If this is a rental or investment property, continue to the Cash Flow Calculator to see how this payment affects monthly income.
How This Calculator Works
This mortgage estimator uses a standard amortization formula to calculate monthly principal and interest payments, then adds estimated monthly property taxes and insurance.
Key assumptions:
- Interest rate remains fixed for the full loan term
- Taxes and insurance are estimated evenly across the year
- PMI and special assessments are not included
This tool provides a realistic baseline—but not a full investment analysis.
When to Use This Calculator
Use the Mortgage Estimator when:
- Evaluating whether a property fits your budget
- Comparing different loan terms or interest rates
- Estimating payments before speaking with a lender
- Stress-testing affordability at higher interest rates
Common Mistakes This Tool Helps Avoid
- Underestimating the impact of property taxes and insurance
- Focusing only on purchase price instead of monthly cost
- Comparing properties without standardizing loan assumptions
- Assuming lender estimates reflect true ownership costs
