Worked out from 34 CFR 685.208 - Repayment plans (Direct Loan Program) and 4 other sources.

An estimate, not a servicer statement or an eligibility determination. Income-driven plan parameters, forgiveness horizons and the tax treatment of cancelled debt are set by regulation and change; confirm your plan terms with your loan servicer.

How this is worked out

3 steps

Monthly rate = 6.53% / 12 = 0.544167%
Payment = P i / (1 - (1+i)^-n) on 30000 over 120 months = 341.1
Paying 100 extra clears the loan in 86 months and saves 3365.36 of interest.
