An amortization chart is provided below that will help you estimate loan repayment at various interest rates, or you can use an online loan repayment calculator.

The chart shows interest rates for five- through thirty-year repayments. Federal loans generally have a repayment period of ten years, while private loans and consolidated loans may have longer periods.

The table shows the monthly payment per thousand dollars of principal. Multiply your total loans (in thousands) by the figure provided below. Remember that loans which are not subsidized have interest which will accrue while you are in school, and thus the principal amount at repayment will be higher than when the loans were originally borrowed.

# of Years 7.66% 8.25% 8% 8.5% 9% 9.5% 10% 10.5%
5 20.11 20.28 20.40 20.52 20.76 21.00 21.25 21.50
10 11.95 12.14 12.27 12.40 12.67 12.94 13.22 13.50
15 9.36 9.56 9.70 9.85 10.15 10.44 10.75 11.06
20 8.15 8.37 8.52 8.68 9.00 9.32 9.65 9.99
25 7.49 7.72 7.89 8.06 8.40 8.74 9.09 9.45
30 7.10 7.34 7.51 7.69 8.05 8.41 8.78 9.15

 

 

For example:

Federal Stafford Loan principal for 3 years of $55,500
Beginning balance with accrued unsubsidized interest is approximately $61,000
Interest rate at 8.25% for ten years would be calculated as follows:
61 x 12.14 = $740.54 per month for ten years
