The snowball method pays off your smallest debt first while making minimum payments on the rest. When a debt is gone, its payment 'rolls over' onto the next smallest balance — building momentum and motivation.
Mathematically, the avalanche method (highest APR first) almost always saves the most interest. The snowball method usually finishes a month or two later but delivers faster psychological wins, which helps most people stick with the plan.
Even an extra $50–$100 a month can shave years off your payoff. Start with whatever you can sustain, then increase it whenever you free up cash — a raise, a side hustle, or a paid-off debt rolling forward.
Most planners suggest building a starter emergency fund of $1,000–$2,000 first, then attacking high-interest debt aggressively while continuing to save. Our Emergency Fund Calculator can size your safety net.
