Frequently Asked Questions

What is the monthly payment on a $400,000 home?
With 20% down ($80,000) on a 30-year mortgage at 7%, your principal and interest payment is $2,129/month. Add property taxes (~$357/mo) and homeowner's insurance (~$167/mo), and your total PITI payment is approximately $2,653/month.
Using the 28% rule, you need a gross income of at least $113,700/year ($9,475/month) to afford the full PITI payment of $2,653/month with 20% down. If you put less down, your payment rises and so does the required income.
A 20% down payment on a $400,000 home is $80,000. A 10% down payment is $40,000, but you'll pay PMI (~$240/mo) until you reach 20% equity. The minimum with a conventional loan is 3% ($12,000), and FHA requires 3.5% ($14,000).
With 20% down and a 7% rate on a 30-year loan, you'll pay approximately $446,440 in total interest over 30 years — nearly as much as the home itself. Making even small extra principal payments each month can shave years off your loan and save tens of thousands in interest.
Rate changes have a big impact. At 6%, the P&I on a $320,000 loan is $1,919/mo. At 7% it's $2,129/mo. At 8% it's $2,348/mo. That's a $429/month swing between 6% and 8% — use the rate slider in the calculator above to model your exact scenario.
