Please see attached for my repayment calculation of USC's fixed-costs (tuition + fees only).
The crux of the spreadsheet:
5-year repayment schedule
Monthly Repayment = $7,236
Yearly Repayment = $86,836
Total Interest = $71,557
Total Repayment = $434,178
10-year repayment schedule
Monthly Repayment = $4,272
Yearly Repayment = $51,263
Total Interest = $150,006
Total Repayment = $512,627
20-year repayment schedule
Monthly Repayment = $2,884
Yearly Repayment = $34,603
Total Interest = $329,448
Total Repayment = $692,069
