How we calculate this
Each month, interest accrues on every debt, minimum payments are made across the board, and any leftover budget — your overpayment plus whatever minimums have freed up from debts you've already cleared — goes entirely to the target debt: highest APR first for avalanche, smallest balance first for snowball.
Avalanche almost always saves more in total interest since it attacks the most expensive debt first. Snowball can still be worth it if clearing a small balance quickly matters more to you for motivation than the extra pounds saved.
