Everything beyond the loan itself adds $562.50 a month — 47% of what you actually pay, and about 87%on top of the loan payment alone. It's the gap between the figure a rate quote shows you and the one that leaves your account.

PMI isn't permanent: on this schedule it drops off automatically around year 14, once the balance reaches 78% of the purchase price — and you can ask to cancel earlier. See exactly when PMI ends and how to remove it sooner.

How much income do you need for a $100,000 mortgage?

Lenders commonly apply the 28% rule— your housing payment shouldn't exceed 28% of gross monthly income. Run backwards from a $100,000 loan at 6.67%, the $643.29 payment implies about $2,297 a month, or roughly $27,570 a year.

That's a floor, not a target: it covers principal and interest only, so adding property tax and insurance pushes the same rule higher. Lenders also apply a 36% back-end ratio counting your other debts, which usually binds first if you carry a car loan or student loans. The home affordability calculator runs both tests together.

$100,000 mortgage payment on a 15-year term

The same $100,000 on a 15-year loan costs about $841.70a month at today's 15-year average of 5.96%, against $643.29 over 30 years. That's roughly $198.41 more each month.

What you buy with it is interest: about $51,506 over the 15-year loan against $131,584 over 30, a saving of roughly $80,079 on the same $100,000borrowed. Two things drive it — half the years of interest, and short-term mortgages price lower, so the rate is better too. The trade is flexibility: that higher payment is committed every month, where a 30-year lets you overpay when you can and stop when you can't. Compare both terms side by side.

How it works

Your principal & interest payment is calculated with the standard amortization formula: M = P × [r(1+r)n] / [(1+r)n − 1], where P is your loan amount, r is your monthly interest rate, and n is the number of monthly payments.

Example: a $100,000 loan at 6.67% for 30 years has a monthly principal & interest payment of about $643.29. Add estimated property tax, homeowners insurance, and any HOA dues to get your total monthly housing payment — the calculator above includes those.
