About this calculator
The tax benefit calculator runs the full itemize-vs-standard deduction comparison and will tell you when you're better off taking the standard deduction — no inflated "savings" numbers.
Disclaimers
- Not financial or tax advice. This is an educational tool. Talk to a licensed mortgage professional and a tax advisor before making decisions.
- State-level estimates. Property tax and insurance numbers are state averages from the Tax Foundation and NAIC — your county, neighborhood, and insurer will quote differently.
- 2026 tax constants (standard deductions and brackets) are based on IRS Rev. Proc. 2025-32.
- Default rate is not a quote. The default 30-year rate is the most recent Freddie Mac PMMS value; lenders quote individual rates based on your credit and loan profile.
