How we calculate
📐

The Three-Part Formula

Gross Monthly = P&I + property tax + insurance + HOA + maintenance.
Cash out-of-pocket = Gross − tax savings.
True cost = Cash out − equity built. Equity isn't a "cost" — it's wealth you're building. The true cost is what homeownership actually takes from your net worth each month.

⚖️

Marginal Tax Savings Only

We only count the extra federal benefit from buying. If you'd take the $30k standard deduction (MFJ) without a home, we subtract that first — so you see savings you gain from homeownership, not savings you'd already have. If someone already itemizes due to high state taxes, we account for that baseline too.

🏛️

SALT Cap ($40k) + $750k Limit

Mortgage interest on the first $750,000 of your loan is federally deductible. Your state and local taxes (property + income) are deductible as SALT, capped at $40,000/year under current law. This cap significantly expands savings vs. the prior $10k limit.

The 30-Year Chart

In early years, most of your payment is "true cost." Over time, two things shift: tax savings shrink (less interest to deduct), while equity building grows dramatically. By year 20–30, the majority of your monthly payment is wealth building — not spending.

🔧

Maintenance Reserve

Budget 1–2% of home value per year for repairs and upkeep. Newer homes need ~1%; older or high-wear homes need ~2%. This is real cash — not a tax deduction — and is commonly underestimated. Select "None" if you prefer not to include it in the estimate.

📈

Appreciation Not Included

This calculator does not account for home price appreciation. If your home gains value over time, your true economic cost could be significantly lower — or even negative. U.S. home prices have historically appreciated ~3–5% per year on average, though this varies widely by market and is never guaranteed.

Estimates only — not tax advice. Savings depend on your full tax picture: other itemized deductions, AMT exposure, income phaseouts, and state-specific rules not captured here. Standard deductions are 2025 figures. The SALT cap ($40,000) reflects the One Big Beautiful Bill (2025) and applies below certain income thresholds — verify with your tax advisor.

State savings are approximate. Always consult a qualified tax professional before making financial decisions.
