Frequently Asked Questions

Common questions about mortgage comparison and calculation

What is a mortgage comparison calculator?

A mortgage comparison calculator helps you compare different mortgage scenarios side by side, including different interest rates, loan terms, and down payments to see which option saves you the most money.

How do I compare different mortgage rates?

Enter your home price, down payment, and property costs once, then input different interest rates and loan terms for each scenario. The calculator will show you the monthly payment difference and total savings.

Should I choose a 15-year or 30-year mortgage?

Use the comparison calculator to see the difference. 15-year mortgages have higher monthly payments but significantly lower total interest costs. 30-year mortgages have lower payments but much higher total interest.

How much can I save by getting a lower interest rate?

Even a 0.25% rate reduction can save thousands in interest over the life of your loan. Use the comparison calculator to see the exact savings for your specific situation.

Does this include all mortgage costs?

This calculator includes principal, interest, taxes, and insurance (PITI). It doesn't include PMI, closing costs, or other fees that should be considered separately.

How accurate are these comparison calculations?

The calculations are very accurate for comparing mortgage scenarios. However, actual rates and terms may vary based on your credit score, lender requirements, and market conditions.

Can I compare different down payments?

Yes, you can enter different down payment amounts for each scenario to see how it affects your monthly payments and total loan costs.

How do property taxes affect the comparison?

Property taxes are the same for both scenarios since they depend on the home's assessed value, not the mortgage terms. The calculator includes them in the total monthly payment.
