Student loan payoff, refinance and payment math

Sketch months to payoff, refinance break-even with your rates, monthly payments, and how extra payments change the timeline. Free, private — we are not studentaid.gov, not a servicer and not a lender.

Payoff calculator Refinance break-even

Educational arithmetic only. KeywordSpy (fetched 2026-11-01) shows strong commercial intent for “student loan calculator” (~49,500/mo, CPC ~$7.13) and “student loan refinance” (~14,800/mo, CPC ~$6.50). FAFSA 2027–28 is live; SAVE enrollment is closed; repayment options and RAP rules are changing. GradClear never invents official IDR quotes or forgiveness decisions — use studentaid.gov.
