How Much is Mortgage on $300k, $400k, $500k House?
$300k house, 20% down ($60k), 6.5% 30yr = $1,967/mo – Total interest $306k
$400k house, 20% down ($80k), 6.5% 30yr = $2,622/mo
$500k house, 12% down, 6.5% 30yr = $3,597/mo with PMI $367/mo
What is PITI? Formula Explained
Formula: M = P [r(1+r)^n] / [(1+r)^n -1] where M=monthly payment, P=loan amount $240k, r=monthly rate 0.0054, n=360 months. Example: $300k price – $60k down = $240k loan at 6.5% = $1,517 P&I + $300 tax + $150 insurance = $1,967/mo total.
Why 20% Down Payment Avoids PMI?
If you put less than 20% down, lenders charge PMI ~1% of loan/year. For $240k loan = $200/mo extra until you reach 20% equity. Our calculator adds it automatically!
