Estimated principal & interest: / month

Illustrative only. Not a commitment to lend. APR and payment depend on credit approval, points, and program.

ARM vs fixed rate mortgage comparison
ARM payments can change after the fixed introductory period—model worst-case caps with your banker.

How to use the result

Compare the payment to 28% or less of gross monthly income as a starting guardrail, then refine with actual taxes and insurance quotes for your property.

If you plan to itemize deductions, consult a tax advisor on how mortgage interest treatment may affect your net housing cost.
