vs. minimum payment
The honest tradeoff
Extended plans lower the monthly — but more than double lifetime interest. Graduated plans help in the first 5 years when your income is lowest, but cost more overall. Even small extra monthly payments ($100–$200) shave years off the loan at 6-7% rates.
How we model each plan
Standard plan is fixed-rate amortization
Same 10 years, same monthly, same formula as any mortgage. Most borrowers default to this — it's usually the cheapest option.
Extended stretches to 25 years
Halves the monthly but more than doubles lifetime interest. Useful if you're drowning, catastrophic if you keep it forever. Refinance when you can.
Extra payments attack principal directly
Every extra dollar reduces principal immediately, shrinking the interest base. At 6-7% rates, $100/mo extra can shave 3+ years off a standard plan.
