Your actual housing payment includes more than the loan. Here's a typical monthly breakdown at 7%:
PMI adds $75–$150/month if your down payment is under 20%. Factor in HOA fees where applicable. The mortgage calculator lets you include everything.
At 7% over 30 years, principal and interest comes to about $998/month. With taxes and insurance, plan for $1,200–$1,450/month.
Under the 28% rule, aim for at least $43,000–$48,000/year gross.
With $30,000 down, you borrow $120,000. At 7% for 30 years: $799/month P&I — and no PMI.
Roughly $100/month per percentage point. At 5%: $805. At 7%: $998. At 8%: $1,100. Over 30 years, that 1% difference means $35,000+ in extra interest.
At 7% for 30 years: about $209,260. Total repayment: $359,260. A 15-year term cuts interest to ~$92,600.
15-year: $1,348/month, $92,600 total interest. 30-year: $998/month, $209,260 total interest. You save $116,660 with the shorter term but need $350 more per month. Run both scenarios.
