Important Considerations:
- Federal Consolidation: Can simplify payments and potentially lower them by extending the term, but may increase total interest paid. It preserves access to federal borrower benefits (like IDR plans, forgiveness). The interest rate is a weighted average rounded up.
- Private Refinancing: May offer a lower interest rate if you have good credit, potentially saving money. However, refinancing federal loans into a private loan means you lose all federal benefits and protections. This is a critical trade-off.
- Extending your loan term generally lowers monthly payments but increases the total interest you'll pay over the life of the loan.
- This calculator provides estimates. Verify all terms with lenders.
