It would depend on how often you are making the repayments. Let's assume you are making the repayments monthly.
This is a present value of an ordinary annuity question.

PV = present value = $19699.20
C = monthly payment
i = interest rate per compounding period = 0.0386/12 = 0.003216666666
n = 12*10 = 120 months
19699.20 = C ((1-(1.00321666666666^-120))/0.0032166666666)
C = 19699.20 / ((1-(1.00321666666666^-120))/0.0032166666666)
19699.20/((1-(1.00321666666666^-120))/0.0032166666666)
So the monthly payment will be $198.14
Total repaid over 10 years = 198.14*120
198.14*120
Interest = 23776.80-19699.20
23776.80-19699.20
[size=150]Total Interest = $4077.60[/size] That is assuming that I haven't made any stupid mistakes.
