Interest accrual is the durable difference from deferment. On a deferment of a Direct Subsidized Loan, the government pays the interest during the pause. There is no equivalent interest subsidy on a forbearance: interest accrues on every loan type during forbearance, including subsidized loans, and the accrued interest is owed and added to what the borrower owes. Whether that interest is then capitalized into principal at the end of the forbearance, so that future interest runs on the higher balance, is genuinely unsettled in the current regulations. 34 CFR 685.205(a) still says forborne interest is capitalized, while the operative capitalization section, 34 CFR 685.202(b), was narrowed in 2022 to leave deferment expiry on an unsubsidized loan as its only listed trigger, and the Department has said it no longer capitalizes in this situation. A borrower should confirm the current treatment with the servicer. Either way, a borrower who takes repeated forbearances watches the debt grow while making no payments.
The 2027 cap on general forbearance is one of the more consequential upcoming changes. For federal student loans made on or after July 1, 2027, 20 USC 1087e(f)(8) caps general discretionary forbearance at nine months in any 24-month period. That reaches only the general forbearance provision at 34 CFR 685.205(a)(1) rather than every category of forbearance. Mandatory forbearances such as those tied to medical or dental residency continue to operate on their own eligibility rules, and the administrative forbearances the Department uses to suspend payments in specific programmatic circumstances are unaffected by the cap.
Most forbearances do not count toward the forgiveness clocks, and the exceptions matter. Public Service Loan Forgiveness counts qualifying monthly payments, not months in which no scheduled payment was due, and forbearance months therefore usually do not count. The generalization has real exceptions written into 34 CFR 685.219(c)(2)(v), which lists specific deferments and forbearances that do count toward Public Service Loan Forgiveness, but a Repayment Assistance Plan borrower cannot rely on those exceptions because the paragraph opens by excluding periods enrolled in that plan. For income-driven repayment forgiveness the general answer is the same, with narrower exceptions built into the specific plan rules.
Forbearance is easy to enter and easy to overuse. Because general forbearance is discretionary, a servicer can and often does offer it as a first-line answer to any borrower who calls about not being able to pay. It is administratively simple, it keeps the account out of delinquency and default, and it costs the servicer nothing. What the borrower gives up in exchange is the interest subsidy, the qualifying-payment count on the forgiveness clocks, and the option of enrolling in an income-driven plan that might have produced a required payment of zero or near zero with all of those benefits intact.
A defaulted loan cannot be placed in forbearance. The default must be cured first, and the routes out of default are their own transactions rather than forbearances.
