About 30-Year Mortgage Payment Calculator
The 30-year fixed is America's default mortgage for a reason: the payment never moves for three decades, and inflation quietly shrinks its real weight every year. The defaults — a $400,000 home, 20% down, 6.6% — produce the PITI figure above: principal & interest plus the escrowed property tax and insurance most servicers collect monthly. Understand the amortization shape before you commit: in year one of the default loan, roughly two-thirds of every P&I dollar is interest; the balance crosses 50/50 only well past the midpoint. That's not a scam — it's arithmetic on a large balance — but it means equity builds slowly early on, and it's why extra principal payments in years 1–10 punch far above their weight. Budget realistically beyond PITI: PMI applies below 20% down (until 20–22% equity), HOA dues are extra, and maintenance runs ~1% of home value yearly. Lenders qualify you to ratios (28/36% rules of thumb); qualify yourself to your actual life — the difference between approved and affordable is where mortgage stress lives.

Frequently asked questions
How much income do I need for this payment?+
Classic guidance caps housing costs at 28% of gross monthly income: the default total above (~$2,600) implies roughly $9,300/month ($112k/year) gross, less if you carry car or student payments (36% total-debt rule). Lenders stretch further; your budget shouldn't have to.
Why is my escrow payment rising every year?+
Property taxes and insurance premiums reprice annually; the servicer recalculates escrow and trues-up shortages — your P&I is fixed, your PITI isn't. In high-insurance states the escrow line can grow faster than wages. Shop insurance at every renewal; it's the one PITI component you control.
Does an extra $200/month really matter on a 30-year loan?+
At the defaults it retires the loan years early and saves a five-figure interest sum — the amortization schedule above shows the baseline to beat. Mark extra payments 'apply to principal'. The earlier the dollars, the bigger the effect: a year-2 prepayment outworks the same amount in year 20 several times over.
Should I buy points to lower the rate?+
One point (1% of loan) typically buys ~0.25% of rate. Break-even = point cost ÷ monthly saving; if you'll hold the loan past that month-count (often 5–7 years) points pay, otherwise skip. Re-run this calculator at the bought-down rate and divide the cost by the payment difference for your exact answer.
