Amortization schedule ($350,000 at 7.5%)
Each year's split between interest and principal, and the remaining balance. Early years are interest-heavy; the principal share grows every year.

The formula behind the payment
P&I = loan × r ÷ (1 − (1 + r)^−n)
r = 7.5% ÷ 12, n = 30 × 12 = 360 payments

Frequently asked questions
4 answers, no funnel.
What is the monthly payment on a 30-year mortgage at 7.5%?
On a $350,000 loan, principal and interest is $2,447 a month. Scale it linearly for other loan amounts: $1,748 on $250k, or $3,496 on $500k, all at 7.5% over 30 years.
How much interest do you pay on a 30-year loan at 7.5%?
A $350,000 loan at 7.5% for 30 years pays about $531,010 in total interest. A shorter term cuts that sharply, because less time at interest is the whole point.
Is 7.5% a good mortgage rate?
A rate is only good relative to what you can get today and what the payment does to your budget. At 7.5%, every $100,000 borrowed costs about $699 a month; compare that against competing quotes and a shorter term before you commit.
Why does a 30-year term change the total cost?
A longer term lowers the monthly payment by spreading principal over more months, but it keeps the balance outstanding longer, so total interest rises. This page's amortization table shows how much of each year goes to interest versus principal.
