highest rate first; minimum elsewhere (avalanche)= 3038.38
Note
This schedule applies the standard amortization formula to the figures you entered. It assumes a fixed rate, payments made on time, and no fees, insurance or rate changes; a real lender's statement will differ.

How does the avalanche method decide which loan to pay off first?+
It directs all extra payment capacity toward whichever of the two loans has the higher interest rate, while paying only the minimum on the other, because that minimizes total interest paid across both debts.
Is avalanche always better than paying loans in the order I feel like?+
Mathematically yes — avalanche always produces the least total interest for a given extra payment amount, though the 'snowball' method (smallest balance first) can be more motivating psychologically even if it costs slightly more.
What happens once the higher-rate loan is paid off?+
All the money that was going to that loan — its old minimum plus any extra — gets redirected to the remaining loan, which accelerates its payoff significantly compared to paying both loans independently.
Does the interest rate difference need to be large to matter?+
Even a modest rate gap compounds over time, so prioritizing the higher-rate loan saves money whenever rates differ at all — the savings just scale with how large the gap is and how much extra you're putting toward debt.
Can I apply avalanche logic to more than two loans?+
Yes, the same principle extends to any number of debts: always send extra payments to the highest-rate balance first, then roll payments down the list in order of rate once each is cleared.
