Debt Avalanche — A Step‑by‑Step 90‑Day Plan
Implement the avalanche method in 90 days. Prioritize highest APRs, automate payments, and track interest saved.
Your 90‑Day Avalanche Plan (2025 Edition)
The avalanche method attacks the highest APR first to minimize total interest and shorten your payoff timeline. This 90‑day plan gives you weekly actions, templates, and checkpoints. Pair it with our calculators to measure results in real time.
Tools you’ll use:
- Avalanche Calculator: /calculator/debt-avalanche-calculator
- Snowball vs. Avalanche (compare): /calculator/snowball-vs-avalanche-calculator
- Budget Calculator (free cash): /calculator/budget-calculator
- Net Worth Tracker: /calculator/net-worth-calculator
Phase 1: Set Up (Week 1–2)
- List every debt: balance, APR, minimum, due date, autopay status
- Order by APR high → low (ties go to smaller balance)
- Automate minimums on all accounts to avoid late fees
- Pick your avalanche target (the top APR)
- Calculate your monthly “extra” payoff amount from the budget
Quick wins in Week 1:
- Call two creditors to request APR reductions or hardship options
- Move due dates to cluster around payday
- Stop new charges; set cards to “auto freeze” after payment where possible
Phase 2: Build Cash Flow (Week 3–4)
- Cut three recurring expenses (streaming, subscriptions, insurance shop)
- Sell one item or gig for a quick $100–$300 boost
- Set an automatic extra payment to the avalanche target on payday
- Create mini sinking funds (e.g., annual insurance) to avoid card reuse
Checkpoint: Update the calculator with your new extra amount; note the new payoff date.
Phase 3: Execution (Week 5–10)
Weekly rhythm:
- Monday: glance at balances and confirm autopay
- Payday: extra payment to the top APR account
- Friday: track interest saved and days shaved off in the calculator
Tactics:
- If a low‑balance loan is within one month of payoff, clear it to free the minimum, then resume avalanche
- If you can qualify for a 0% transfer with a modest fee, run the math; only transfer what you can finish in promo
Mindset:
- No skipped weeks—small extra payments still compound
- Celebrate each $1,000 reduction with a free reward (walk, library day, park picnic)
Phase 4: Roll‑Up and Re‑Forecast (Week 11–12)
- When the top APR debt is gone, roll its entire payment onto the next highest APR (the snowball effect)
- Re‑run the calculator with the new payment to get your updated payoff date
- If motivation is lagging, consider one tiny “snowball” win on a small balance, then return to avalanche
Example Timeline (Illustrative)
- Month 1: $6,500 at 26.99% (target), $3,200 at 19.99%, $2,800 at 17.49%
- Extra: $300/mo → $450/mo after budget cuts
- Result: Target card gone in 6–7 months; roll payment to 19.99%; overall payoff 4–6 months faster vs. minimums
Consolidation and Balance Transfers (Use Carefully)
- Consolidation loan: One payment, fixed rate; only do it if APR truly drops and term isn’t too long
- 0% balance transfer: Pay fee, finish before reversion APR, avoid purchases on transfer card
Avoid These Common Avalanche Pitfalls
- Letting one emergency wipe out momentum—use a small emergency fund (even $500–$1,000)
- Overly long consolidation terms that lower payment but raise total interest
- Missing autopay and triggering late fees that erase progress
- Ignoring annual fees or deferred interest clauses
FAQs
Is avalanche always best?
It’s best for minimizing interest. If you struggle to stay motivated, start with one tiny snowball win, then return to avalanche.
Can I combine avalanche with 0% transfers?
Yes. Transfer only what you can finish in time and keep the rest in avalanche order.
How big should my emergency fund be while paying off debt?
Enough to prevent reusing cards for predictable expenses—often $500–$1,000 to start, then grow as balances fall.
