How the math works

Avalanche (highest rate first):  18 months, $832.97 total interest
Snowball  (smallest balance first): 21 months, $1,074.22 total interest

Avalanche directs every extra dollar to whichever debt has the highest interest rate; snowball directs it to whichever debt has the smallest balance. Avalanche usually saves more in total interest — here, $241.25 less — but snowball clears individual debts sooner, which can matter more in practice than the math alone.
