15-year vs 30-year on $900,000
At 6.5%, the 15-year payment is about $7,840 against $5,689 on the 30-year schedule. The higher payment retires the loan in half the time and cuts total interest from about $1,147,900 to about $511,194, so the choice generally trades monthly flexibility against lifetime cost.
If $900,000 is the home price, not the loan
A 20% down payment of $180,000 on a $900,000 home leaves a $720,000 loan, and the 30-year payment at 6.5% drops to about $4,551. The calculator below adds property tax and insurance to produce the full monthly figure lenders call PITI.
Going the other direction, the house affordability tables start from an income and work toward a price, and the free rent vs buy calculator checks whether buying beats renting over your horizon.

PITI omits HOA dues. The PMI estimate applies while the down payment is under 20% and generally falls away once the balance reaches 80% of the original value; the exact rate depends on credit and loan type.
Common questions
- What is the monthly payment on a $900,000 mortgage?
- At a 6.5% rate, the principal and interest payment on a $900,000 mortgage is about $5,689 per month on a 30-year term and about $7,840 on a 15-year term. Across rates from 5% to 8%, the 30-year payment generally falls between $4,831 and $6,604. Property taxes, homeowners insurance, and any mortgage insurance are added on top of these figures.
- How much income is generally needed for a $900,000 mortgage?
- A common lending guideline caps housing costs at 28% of gross income. On principal and interest alone at 6.5% over 30 years, that guideline points to gross income of about $20,316 per month, roughly $244,000 per year, and taxes, insurance, and other debts raise the requirement from there.
- How much total interest does a $900,000 mortgage cost?
- At 6.5%, total interest comes to about $1,147,900 over a 30-year term. The same rate on a 15-year term reduces total interest to about $511,194, in exchange for the higher monthly payment.
