Paying off federal and private student loans
Student loan debt is unusual in that it's common to be paying off several loans at once — a mix of federal Direct or subsidized/unsubsidized loans and, for some borrowers, private loans from a bank or credit union. This calculator lets you list every loan together, tag each as federal or private, and see one combined payoff timeline using either the avalanche or snowball method.
Federal vs. private: what stays different
Tracking loans together here doesn't erase the real differences between them. Federal loans qualify for income-driven repayment plans and programs like Public Service Loan Forgiveness (PSLF); private loans generally don't. If you refinance federal loans with a private lender to get a lower rate, you give up access to those federal protections — worth weighing carefully before refinancing.

Frequently asked questions
You can track them together here to see one combined payoff date, but federal and private loans behave differently for refinancing, forgiveness, and income-driven repayment — keep that distinction in mind before consolidating or refinancing across both.
No — this models a straightforward fixed payoff (minimum payments plus any extra you add), the same way avalanche/snowball payoff works for any debt. Income-driven plans, PSLF, and other forgiveness programs follow different rules and aren't modeled here.
Refinancing can lower your rate if your credit and income qualify, but federal loans lose access to income-driven repayment and federal forgiveness programs once refinanced with a private lender. Refinancing purely private loans has no such downside.
