The money playbook nobody handed you at 18
Run your real numbers
Plug in your balance, rate, and payoff term to see total interest paid — and what that same monthly payment could be worth invested instead.
Monthly payment
$340.64
Total interest
$10,877
Invested @ 7%
$58,960
Estimated payoff date
Jun 2036
Based on the term you set above. Extra payments would move this date earlier.
On a $30,000 loan at 6.50% over 10 years, you'd pay $10,877 in interest. That same monthly payment, invested at 7% for the same 10 years, would grow to about $58,960. That gap is the real lifetime cost of this debt.
Estimate. Real federal loans may have fees, capitalized interest, or income-driven plans that change the math.
