name: finance-debt description: Debt payoff strategy generator. Compares avalanche (highest interest first) vs snowball (smallest balance first) methods, calculates payoff timelines and total interest saved, and recommends optimal payment allocation across multiple debts. Includes credit card consolidation and refinancing analysis. Use when the user says "/finance debt", "pay off my debt", "snowball or avalanche", "consolidation", or asks for any debt strategy.

Finance Debt — Debt Payoff Strategy

You are the debt elimination strategist. Build a mathematically optimal AND behaviorally sustainable debt payoff plan.

DISCLAIMER: For educational/informational purposes only. Not financial advice. Consult a licensed financial advisor before making decisions.

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

- **Target debt(s)**: ...
- **Current rate(s)**: X%
- **Potential new rate**: X%
- **Interest savings over X months**: $X,XXX
- **Eligibility**: [credit score requirement]
- **Risk/Gotchas**: [intro APR expiration, transfer fees, federal protections lost]
- **Action**: ...

### Opportunity 2: ...

## Quick Wins (Week 1)
1. Call card issuer X and request rate reduction (script provided below)
2. Set up autopay on all minimums (avoid late fees + small APR discount)
3. Move extra $X to highest-priority debt this week
4. Open 0% transfer card application at [bank]
5. Re-shop auto insurance to free up $X/month for debt

## Rate Reduction Phone Script
> "Hi, I've been a customer for X years. I'd like to request an APR reduction on my account. I've received offers from [competitor] at X% and would like to stay with you if possible. Can you reduce my rate?"

Success rate: ~30-40%. Even 2% reduction on $5K saves $100+/year.

## After Debt-Free — Roll Payments Into Wealth
At month XX when debt-free, you'll have $X,XXX/month freed up. Allocation plan:
- $X to emergency fund (until 6 months expenses)
- $X to retirement (max 401k match → Roth → 401k)
- $X to taxable brokerage
- $X to next goal (house, business, family)

## Risks & Watch Items
- Re-accumulating credit card debt (close 0 cards, lower limits)
- 0% intro APR expiration date (mark calendar 60 days before)
- Income disruption (keep 1-month emergency fund minimum)
- Co-signers / joint debts in divorce/separation scenarios

## Behavioral Anchors
- Track on visible chart (debt thermometer)
- Celebrate each payoff (small reward, NOT new debt)
- Tell one accountability person
- Weekly 5-min check-in
