Building a debt payoff plan from scratch
Before you pick avalanche or snowball, you need the thing most people never make: a complete, honest map of what you owe.
Most people arguing about avalanche versus snowball have skipped the step that actually matters: they've never written down everything they owe in one place. A payoff plan isn't a method — it's a map plus a monthly attack number plus automation. Get those three right and the method is a footnote.
Step one: the full inventory
Put every debt in one list: balance, interest rate, minimum payment, and due date for each. All of it — cards, loans, medical bills, the money you owe a sibling. The act of seeing the complete picture, often for the first time, is worth more than any payoff trick. You can't attack a total you've never actually added up.
| Debt | Balance | APR | Minimum | Due date |
|---|---|---|---|---|
| Store card | $900 | 29.9% | $30 | 5th |
| Credit card A | $6,500 | 24% | $150 | 12th |
| Car loan | $11,000 | 7% | $290 | 20th |
| Medical bill | $1,400 | 0% | $50 | 1st |
Step two: find your attack number
Add up all the minimums — that's your baseline. Your attack number is the fixed extra amount, above total minimums, you'll send every month to one target debt. Even $150 changes the trajectory; $500 transforms it. That number comes from the same three places it always does: cutting expenses, selling things, and adding income. Debt payoff is a cash-flow project in a spreadsheet costume.
Step three: automate the machine
- 1Autopay every minimum
One 30-day late mark costs more than any method saves — never miss a minimum on the 'ignored' debts.
- 2Schedule the attack payment
Send your extra to the target debt the day after payday, before it becomes groceries.
- 3Roll payments forward
When a debt dies, redirect its entire payment — minimum plus attack — to the next target the same month.
- 4Freeze new debt
Stop charging during payoff, or you're bailing a boat while drilling new holes in it.
The bottom line
A debt payoff plan is three things: a complete inventory of every balance, rate, minimum, and due date; a fixed monthly attack number above your minimums; and automation that pays minimums, fires the attack payment on payday, and rolls each dead debt's payment onto the next. Choose avalanche or snowball last — it's the smallest decision here. The plan that beats a perfect spreadsheet is the boring one you actually automate and finish.
