Payoff order (avalanche)

1. Credit card$6,000 · 21% rate

2. Line of credit$8,000 · 9.5% rate

3. Car loan$15,000 · 7.5% rate

ASSUMPTIONS — Both plans use the same fixed monthly budget (your minimums plus the extra payment); as each debt clears, its payment rolls onto the next target. Interest accrues monthly on each balance and rates are assumed fixed. Real cards and lines of credit may charge fees or change rates. Payoff order is set once from today's balances and rates.
