This is an illustrative composite based on typical debt situations — every number below comes from an actual payoff simulation. Names and details are fictional.
The starting line
Dana and Marcus weren't in crisis. They made their payments every month. That was exactly the problem — the payments were all they made, and the balances barely moved. Their picture:
| Debt | Balance | APR | Payment |
|---|---|---|---|
| Card A (store card) | $4,200 | 26.9% | $110 |
| Card B | $7,800 | 23.4% | $200 |
| Car loan | $11,400 | 7.2% | $340 |
| Total | $23,400 | $650 |
Running those exact numbers: keeping the same $650 in payments, they'd be debt-free in 54 months — four and a half years — and pay about $11,000 in interest along the way.
The plan: snowball + $350
They chose the snowball (smallest balance first) over the avalanche, deliberately. Dana had quit two payoff attempts before, and they knew a fast first win mattered more to them than optimal math. Then they went hunting for extra money and found $350/month: $180 from a grocery overhaul, $110 from canceling and renegotiating subscriptions and insurance, and $60 from Marcus selling on eBay a couple weekends a month.
Every month: minimums on everything, $350 extra to the target debt, and each paid-off debt's payment rolled into the next — the snowball.
The timeline, month by month
- Month 9: Card A gone. The $110 payment plus the $350 extra ($460 total) rolls to Card B. The fridge chart gets its first big X — and the plan survives its first hard month because the win came early.
- Month 12 checkpoint: a $1,100 tax refund goes straight in (they'd pre-committed 90% of any windfall). Card B's projected payoff jumps two months closer — seeing that jump in the calculator was, in their words, better than spending the refund.
- Month 21: Card B gone. Now $660/month plus the car's $340 all point at the car loan — over $1,000/month against a 7.2% balance.
- Month 28: car loan finished. Debt-free — 26 months ahead of schedule.
The final scoreboard
| Minimums only | Their plan | |
|---|---|---|
| Time to debt-free | 54 months | 28 months |
| Total interest paid | ~$11,000 | ~$4,300 |
| Interest saved | ~$6,700 | |
And the part nobody talks about: on month 29, they kept the habit but flipped the target — the same $1,000/month started filling a freedom account and an emergency fund. Eight months later they had a full buffer and every irregular expense funded. The machine that got them out of debt is the same machine that keeps them out.
