After five years you would still owe about $567,138, and after ten years about $519,616. The amortization calculator shows the full schedule, and the early payoff calculator shows what extra payments save.

    Income and home price

    Keeping principal and interest to 28% of gross pay takes an income of about $178,041. Property tax, insurance and PMI come on top, so the real figure is higher. With 20% down, a $600,000 loan buys a $750,000 home; with 10% down, about $666,667. To work backward from your income, try the home affordability calculator.
