Debt Avalanche Payoff Planner

Why this is epic

Debt avalanche (highest-interest first) is math-optimal — saves more than debt snowball (smallest-first) across realistic scenarios. Research: typically $500-2000 saved on $20-50K debt.

Avalanche needs patience (first debt may take longer). Snowball gives psychological wins sooner. Both valid; avalanche wins on pure math.

Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.

📝 Input

<debts>
Card A: $5000 at 22%, min $100/mo
Card B: $3000 at 18%, min $60/mo
Student loan: $45000 at 6.5%, min $450/mo
Auto loan: $8000 at 4%, min $200/mo
</debts>
<extra-monthly-available>$400 beyond minimums</extra-monthly-available>
<income-monthly-post-tax>$6200</income-monthly-post-tax>

🤖 Output

Debt Prioritization (avalanche order)

1. Card A — 22% → attack first

2. Card B — 18% → second

3. Student loan — 6.5% → third

4. Auto loan — 4% → fourth (lowest rate)

Monthly Allocation

Card A: $500 ($100 min + $400 extra)
Card B: $60 (min only)
Student loan: $450 (min only)
Auto loan: $200 (min only)

Total: $1210/month debt service (19% of post-tax income — manageable)

Payoff Timeline

Month 1-11 (Card A payoff): $500/mo on Card A ($5000 balance + $550 interest over period = 11 months)

Month 12 (Card A gone): Card B now gets $560/mo ($60 + $500 rolled from Card A)

Month 12-18 (Card B payoff): $560/mo pays off $3000 + interest in ~6 months

Month 18 (Card B gone): Student loan now gets $1010/mo ($450 + $560 rolled)

Month 18-60 (Student loan payoff): $1010/mo pays off $45K at 6.5% in ~48 months from month 18 start = total ~5.5 years from today

Month 60+ (Student loan gone): Auto loan at minimums finishes around same time; extra $1210/mo available for investing

Comparison vs. Minimums-Only

Minimums-only total interest over life of debts: ~$28,000

Avalanche + $400 extra total interest: ~$14,000

Savings: ~$14,000 over payoff period

Time to total debt freedom:

Minimums only: ~10-12 years
Avalanche + $400: ~5.5 years

Milestones

Month 11: Card A gone — celebrate (small). Major psychological win.
Month 18: Card B gone — credit cards fully eliminated. Significant.
Month 60: Student loans gone — biggest debt eliminated. Life-changing for future optionality.
Month 60+: Auto finishes, $1210/mo → investing. Wealth-building begins.

Assumes income stable, extra $400/mo maintained. Any increases in income should accelerate timeline further.

Common use cases

Post-snowball graduates wanting optimization

Pro tips

List all debts with: balance, interest rate, minimum payment.
Put every extra dollar on highest-rate. Minimums on everything else.
Once top debt paid, ROLL that payment into next-highest.
Snowball method: smallest-first. Different pro-con; both valid.

Customization tips

For balance transfer opportunities: 0% APR intro transfer can accelerate avalanche. Watch fees (3-5% typical). Math out break-even.
For variable income (freelance): use 'base floor' for minimums + additional when available. Don't over-commit base.
For people struggling psychologically with avalanche: switch to snowball temporarily. Any payoff progress beats stuck.
For debts in collections: different conversation. Negotiate settlement amount first; avalanche AFTER negotiation complete.
For student loan specifically at 6.5%: above market returns but below panic. Some argue parallel investing makes sense; depends on tolerance.

Variants

Default Avalanche

Standard highest-rate-first

Avalanche + Emergency Fund Parallel

Build emergency + debt simultaneously

After Credit-Card (Student Loan Focus)

Post-CC payoff; student loan optimization
