What Is Income-Driven Repayment?
Income-driven repayment (IDR) plans are federal programs that calculate your monthly student loan payment as a percentage of your discretionary income — typically 5–20% — rather than based on your total loan balance. After a set repayment period (20–25 years depending on the plan), any remaining balance is forgiven.
IDR plans are only available for federal student loans. Private student loans are not eligible.
The Current IDR Plans
| Plan | Payment Cap | Forgiveness After | Best For |
|---|---|---|---|
| SAVE (Saving on a Valuable Education) | 5% of discretionary income (undergrad loans) | 20–25 years | Most borrowers — typically lowest payments |
| PAYE (Pay As You Earn) | 10% of discretionary income | 20 years | Borrowers who qualify and have high debt relative to income |
| IBR (Income-Based Repayment) | 10–15% of discretionary income | 20–25 years | Older borrowers; widely available |
| ICR (Income-Contingent Repayment) | 20% of discretionary income | 25 years | Parent PLUS loan borrowers (via consolidation) |
IDR plan rules have been subject to legal challenges. Verify current plan availability at studentaid.gov.
How Payments Are Calculated
"Discretionary income" in the IDR context is typically your adjusted gross income minus 150% of the federal poverty level for your family size. For the SAVE plan, the calculation is more generous (225% of the poverty level threshold), resulting in lower payments for many borrowers.
If your income is low enough, your calculated payment could be $0/month — and those $0 months still count toward the forgiveness clock.
Public Service Loan Forgiveness (PSLF)
If you work for a qualifying government or nonprofit employer, PSLF forgives remaining federal loan balances after 10 years (120 payments) of qualifying payments under an IDR plan. This is separate from the 20–25 year standard IDR forgiveness. PSLF forgiveness is currently tax-free at the federal level.
KC employees in manufacturing and corporate roles typically work for a for-profit employer and would not qualify for PSLF. However, family members in government, healthcare, education, or nonprofit sectors may qualify.
The Tax Bomb Warning
Under standard IDR plans (not PSLF), the forgiven amount at year 20–25 is treated as taxable income in the year of forgiveness. If $80,000 in loans is forgiven, you may owe $15,000–$25,000+ in taxes that year. Planning for this is essential — saving in a dedicated account during repayment is one approach.
How to Enroll
You can apply for income-driven repayment at studentaid.gov. Annual income recertification is required to stay on the plan. Missing recertification causes your payment to revert to the standard 10-year payment amount.
