How to Use This Calculator
Compare three popular student loan payoff strategies to see which one saves you the most money and gets you debt-free fastest.
Debt Avalanche: Prioritizes loans by highest interest rate. Mathematically optimal - saves the most money.
Debt Snowball: Prioritizes loans by smallest balance. Psychologically motivating - gets quick wins.
Standard: Pays loans in the order you entered them without optimization.
Estimate payoff timeline and interest burden across multiple student loans to prioritize extra payments strategically.
Formula
For each loan: Interest_t = Balance_t * Monthly Rate; New Balance = Balance + Interest - Payment; aggregate until payoff.

Frequently Asked Questions
Should I target highest interest loan first?
Yes for cost minimization. Paying extra toward the highest APR balance typically reduces lifetime interest fastest.
Can refinancing change the outcome?
Often yes. A lower blended interest rate can materially improve payoff speed and total borrowing cost.
