  • Forgetting taxes, insurance and HOA.

FAQ

Does the payment include taxes and insurance?

They are shown separately here; lenders often escrow them, so the actual payment is higher.

How much difference does 15 vs 30 years make?

A 15-year loan has a higher payment but less total interest; change the term in the same calculator to compare.

Should I calculate the down payment percentage?

Down payment divided by price is the percentage; below 20 percent may add PMI, which this tool does not include.
