Student loan payoff example
This worked example compares a current student loan payment with an accelerated version that adds extra principal each month.
Calculated answer
On a $40,000 balance at 5.5% interest, the baseline payment is $225 per month. Adding $50 extra changes the payoff path to 241 months and an estimated interest cost of $26,068.

The shared debt-payoff simulation compares the existing payment with an accelerated payment to estimate whether the extra amount meaningfully changes the timeline.
