Understanding this calculator

The payment a lender quotes is usually just principal and interest; the payment that hits your bank account includes property taxes, homeowners insurance, possibly HOA dues, and PMI if you put down less than 20%. Budgeting on the full number — PITI — is the difference between a comfortable house and a house-poor one.

Two structural facts about amortized loans surprise people. Early payments are mostly interest — on a 30-year loan at 6–7%, roughly two-thirds of the first years' payments go to interest, with equity building slowly. And the lifetime interest is enormous: often 80–120% of the amount borrowed at today's rates. That's why the payoff calculator next door, showing what extra payments do, pairs well with this one.

Heading into retirement, the calculus shifts from "how much house can I afford" to "does carrying this payment into fixed-income years make sense" — a question of cash flow, not just interest math.

Assumptions and methodology

  • Principal & interest uses the standard amortization formula on the loan amount (price − down payment).
  • PMI applies when the down payment is under 20%, at your chosen annual rate on the loan amount, and drops when the balance amortizes to 80% of the price (a simplification of lender rules).
  • Taxes, insurance, and HOA are passed through from your inputs — they don't amortize and typically rise over time.
  • The amortization summary is annual; escrow changes, rate adjustments (ARMs), and closing costs are not modeled.

Common questions

What's PMI and how do I avoid it?

Private mortgage insurance protects the lender when you put down less than 20%. It typically runs 0.3–1.5% of the loan per year and can be removed once you reach 20–22% equity.

15-year or 30-year?

A 15-year loan carries a lower rate and a fraction of the lifetime interest, but a much higher required payment. Some buyers take the 30 for flexibility and pay it like a 15 — the payoff calculator shows what that does.
