$900,000 mortgage payments by rate and term
| Rate | 30-year P&I | 20-year P&I | 15-year P&I | Total interest (30-yr) |
|---|---|---|---|---|
| 5.5% | $5,110.10 | $6,190.99 | $7,353.75 | $939,636 |
| 6.0% | $5,395.95 | $6,447.88 | $7,594.71 | $1,042,544 |
| 6.5% | $5,688.61 | $6,710.16 | $7,839.97 | $1,147,900 |
| 7.0% | $5,987.72 | $6,977.69 | $8,089.45 | $1,255,580 |
| 7.5% | $6,292.93 | $7,250.34 | $8,343.11 | $1,365,455 |
Two lessons hide in that table. First, the rate matters enormously: the spread between 5.5% and 7.5% on $900,000 is $1,182.83 every month. Second, the term is the biggest interest lever you control — the 15-year column pays the loan off in half the time for a fraction of the interest. Compare the two structures in depth with the 15 vs 30 year calculator.
What a $900,000 loan really costs per month
Principal and interest at 6.5%/30yr are $5,688.61. Add property taxes and insurance for a typical property at this price (roughly $1,012.50 a month combined, varying hugely by state — check yours in the state cluster) and the realistic bill lands near $6,701.11. Budget from that number, not the headline P&I.
