Why the standard deduction matters
Many calculators just multiply your interest by your tax rate — and skip the standard deduction entirely. Since the 2017 tax law roughly doubled the standard deduction, most homeowners today get little or no extra tax benefit from itemizing, because they’d already claim as much or more via the standard deduction. This calculator checks that explicitly.

Itemizing likely beats the standard deduction for your situation.
Your estimated itemized deductions ($27,135) come out above the Single standard deduction ($15,000) — so itemizing likely gives you a real tax benefit from the mortgage interest deduction.
Deduction Breakdown
| Item | Amount |
|---|---|
| Year-one mortgage interest | $22,635 |
| Property tax deduction | $4,500 |
| Total itemized deductions | $27,135 |
| Standard deduction (Single) | $15,000 |
| Benefit from itemizing | $12,135 |
| Est. tax savings (22% bracket) | $2,670 |
This only counts mortgage interest and property tax (capped at $10,000combined with any other state/local taxes, per current SALT rules) as itemized deductions — it doesn’t account for other deductions you may have, like charitable giving or medical expenses, so your real total could be higher. Standard deduction figures are approximate for the current tax year and change annually with inflation. This is an estimate, not tax advice — a tax preparer can confirm your actual numbers.
