Example payoff
How avalanche works
Debt stack
Avalanche attacks the 18% credit card first
Even though the personal loan is bigger, the 18% APR costs more in interest per month. Pay it first.
Result
Lowest total interest, fast payoff
vs. Snowball: save ~$800–$1,200 in interest
Why It Works
The math is simple: high interest costs more each month.
Every dollar you don't pay toward a high-rate debt is a dollar that gets charged interest next month. Avalanche eliminates expensive debt faster, saving you money you can use to pay down the rest.
Maximize Interest Savings
Pay down high-APR debt first to minimize total interest paid over the payoff timeline.
Mathematical Optimization
Avalanche is the mathematically optimal strategy when you want the lowest total cost.
Clear Prioritization
No guessing—attack debts with the highest interest rates first, every single month.
Faster Overall Timeline
Less interest means more principal paydown per payment, shortening your total payoff time.
