At 6.5%, interest alone on $875,000 runs about $4,739.58 per month — roughly $155.82 every day. That's the number amortization slowly kills: each payment shrinks the balance, so each month a little less goes to interest and a little more to principal. See the month-by-month schedule, or try our daily interest calculator for per-diem closing math.
Principal and interest is the floor, not the payment. A realistic budget adds property taxes, homeowners insurance, HOA dues, and — under 20% down — mortgage insurance, which our full calculator prices the way a lender does: FHA and USDA from the official tables, VA's funding fee, and conventional PMI by credit score.
A common guideline caps total housing costs near 28–36% of gross income, but real qualifying depends on your full debt picture, credit and loan program. Build the complete payment in the calculator, then ask a licensed professional — Phil answers questions free.
