What changes this most?
The highest-rate debt is creating the largest mathematical drag, which is why avalanche reduces interest in this model.
Sensitivity check
A roughly 10% move in debt 2 rate changes the modeled headline result by up to $200 in this setup.
Avalanche often minimises interest mathematically; snowball can provide earlier balance wins. The best practical method is the one you can consistently follow.

Formula
Both methods make minimum payments on all debts and direct the extra payment to one target: lowest balance first for snowball, highest interest rate first for avalanche.
Adjust one assumption at a time to understand which inputs have the greatest effect. Compare several realistic scenarios rather than relying on a single projection.
