When to Use
Trigger when the user says:
/finance debt- "Pay off my debt"
- "Avalanche or snowball"
- "Debt consolidation"
- "Refinance my loans"
- "Get out of debt"
- "Credit card payoff"
Data Collection
For each debt, collect:
- Type (credit card, student loan [federal/private], auto, personal, medical, HELOC, mortgage)
- Balance (current)
- APR (interest rate)
- Minimum payment
- Optional: original balance, term remaining, autopay discount
Then ask:
- Total monthly payment budget for debt (minimums + extra)
- Credit score (for refi/consolidation eligibility)
- Any windfalls expected (tax refund, bonus, inheritance)
- Goal: fastest payoff / lowest interest / lowest monthly payment / psychological wins
Strategy Comparison
Avalanche Method (Mathematically Optimal)
- Pay minimums on all debts
- Send ALL extra to highest-interest debt
- When paid off, roll that payment to next highest-rate debt
- Pro: Lowest total interest paid, shortest payoff
- Con: Slower psychological wins if highest-rate has biggest balance
Snowball Method (Behaviorally Optimal)
- Pay minimums on all debts
- Send ALL extra to SMALLEST balance
- When paid off, roll payment to next smallest
- Pro: Quick wins, momentum, behavioral success rate
- Con: Higher total interest paid
Hybrid Method (Best for Most)
- Pay off any debt <$1,000 first (1-2 quick wins)
- Then switch to Avalanche
- Or: Avalanche but knock out any debt that finishes within 6 months first
Calculation Engine
Step 1: Payoff Timeline per Debt
For each debt, calculate:
Months to payoff = -log(1 - (Balance × monthly_rate)/payment) / log(1 + monthly_rate) Where monthly_rate = APR / 12 Total interest = (payment × months) - balance
Step 2: Run Both Strategies
For Avalanche:
- Sort debts by APR descending
- Apply extra to debt #1 until paid off
- Roll its payment to debt #2
- Calculate cumulative months and total interest
For Snowball:
- Sort debts by balance ascending
- Apply extra to debt #1 until paid off
- Roll its payment to debt #2
- Calculate cumulative months and total interest
Step 3: Show the Delta
- Avalanche saves $X in interest vs Snowball
- Snowball pays off first debt X months sooner
- Recommendation based on user's goal preference
Consolidation Analysis
Option A: Balance Transfer Credit Card
- Target: high-interest cards (>18%)
- Look for: 0% intro APR 15-21 months, 3-5% transfer fee
- Math: Compare (transfer fee + remaining balance after intro) vs (interest paid keeping current cards)
- Requires: 670+ credit score typically
Option B: Personal Loan Consolidation
- Target: 3+ cards or mixed unsecured debt
- Rates: 7-15% depending on credit
- Pro: Fixed payment, fixed term, lower rate than cards
- Con: Doesn't fix spending behavior
Option C: Student Loan Refinancing
- Federal loans: WARNING — refinancing forfeits PSLF, IDR, deferment
- Private loans: nearly always worth shopping
- Target: rates 1%+ below current
Option D: Mortgage Refinancing
- Rule of thumb: refinance if new rate is 0.75%+ below current AND you'll stay 3+ years
- Calculate breakeven: closing costs ÷ monthly savings = months to breakeven
Option E: HELOC for High-Interest Debt
- Use sparingly: converts unsecured to secured (home at risk)
- Only if disciplined enough not to re-rack up cards
