What these numbers mean for you
Over 30 years, you'll pay $480583 in interest - that's 133% of your loan amount.
Principal & interest is only 80% of your true monthly cost. The rest is taxes, insurance, and fees.
Your true monthly housing cost is $2,935, not the $2,335 that most calculators show. Over 30 years, you'll pay a total of $1,056,583 — that's $480,583 in interest alone.
