M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
- M = Monthly payment
- P = Principal
- i = Monthly interest rate
- n = Payments (term × 12)
Example:
$30,000 at 5.5% for 10 years = $326/month
2. Income-Driven Repayment (SAVE Plan)

Payment = (AGI - 225% Poverty Line) × 5-10%
Example:
$50,000 income – $32,805 (225% line) = $71/month
3. Loan Forgiveness Projections
- PSLF: 120 qualifying payments
- IDR Forgiveness: 20-25 years
