**drwls**, Wednesday, March 12, 2008 at 3:00pmThis looks like an exercise in Table reading, but the table is hard to read.

The 25-yr load entry in the 9.5% interest row is $8.73. That would be the monthly payment. 25 years is 300 months, so the total amount repaid would be $8.73 times that, or $2619.00

Of that amount, $1619.00 would be interest charges over the life of the loan. The rest is the return of the $1000 principal.

**Jen**, Wednesday, March 12, 2008 at 4:59pmWhat is the monthly payment on a 25-year loan of $125,000 if the

annual interest is 9.5%

So for the 125,000 loan

monthly payment will be 8.73*125000/1000 = 1091.25

What are the total interest charges over the life of the loan?

1091.25*300 = 327375

Total Interest = 327375-12500 = 202375

Is this correct
