it depends: $197,591.00 if you count 52 weeks per year; $198,851.28 if you count 365.25 days per year and 7 days per week.

Step-by-step explanation:

If we consider a year to be 52 weeks, then the total number of payments is ...

25*52 = 1300

The total amount paid is then ...

1300*$315.07 = $409,591.00

The difference between this and the loan amount is the interest paid:

$409,591 - 212000 = $197,591

__

If you take into account the extra days in each year and the leap years, very likely there would be 4 more payments in 25 years. Then the total interest is ...

1304*$315.07 - 212,000.00 = $198,851.28
