The SAVE (Standard vs. Alternate Valuation Estimate) plan is actually a term used in estate planning rather than for federal student loans. It refers to the valuation method used for estate tax purposes when someone passes away.
For federal student loans, there are various repayment plans available, such as the Standard Repayment Plan, Income-Driven Repayment Plans (like Income-Based Repayment, Pay As You Earn, Revised Pay As You Earn, and Income-Contingent Repayment), as well as options for loan forgiveness, like Public Service Loan Forgiveness (PSLF) and Teacher Loan Forgiveness.
