High-Interest Debt Elimination

Every dollar above 6% is working against you

You've protected your income, built a starter cushion, and locked in the match. Now clear the one thing still shrinking your net worth every day: debt charging more than 6%.

Your goal Every debt above 6% paid to $0, typically within 12–36 months.
What & why

Paying it off is a guaranteed return.

Paying off a debt earns you exactly its interest rate — risk-free. At credit-card rates, that's a return the stock market can't reliably match.

24%

The average credit card APR in 2024 — the highest Bankrate has recorded. A $10,000 balance costs about $2,400 a year in interest, every year you carry it.

Why 6%? Below it, expected investing returns beat paying the debt early, so you pay minimums and invest. Above it, payoff wins. Fidelity's research, JL Collins, White Coat Investor, the Bogleheads and Money Guy all land in the same place. Debts below 6% (most mortgages, many student loans) wait for Step 17.

Recommended
Avalanche

Highest interest rate first. Saves the most money.

Alternative
Snowball

Smallest balance first. Quicker wins keep some people going. If you'll stick with it better, use it.

Either way
Roll it over

When one debt hits $0, its whole payment rolls to the next.

Recommended setup

A fixed extra payment, every payday

Minimums on autopay; one extra payment to one target

Treat the extra payment like a bill, not a choice.

Do it

Five moves

List your above-6% debts, highest rate first.
Pull them from your Step 2 snapshot — name, balance, rate, minimum. The calculator can do the sorting for you.
Put every minimum payment on autopay.
Then don't touch them again. Your only decision is where the extra dollar goes.
Automate a fixed extra payment to the top debt.
Even $100/month matters at credit-card rates. When that debt hits $0, roll its whole payment to the next one.
Send every windfall to the balance.
Tax refund, bonus, gift, side income — straight to the top-rate debt.
Try to lower the rate.
Call your card issuer and ask, or use a 0% balance transfer — only if you can clear it before the promo ends.
You're done when

Zero balance, zero drag

Every debt above 6% shows a $0 balance, confirmed in your tracker.
Anything left is below 6% and on autopay minimums — and the money you were sending to creditors is now free for the next step.
Questions

Common questions & mistakes

Avalanche or snowball — which should I use?
Avalanche saves the most interest. Snowball gets finished more often, because quick wins keep people going. A plan you finish beats an optimal one you abandon. Pick one and don't switch.
Why can't I just invest instead?
Paying off a 22% card is a guaranteed 22% return. The market averages roughly 10% and guarantees nothing.
My student loan is 4.5% — should I pay it off faster?
Not in this step. Pay the minimum and decide in Step 17 whether to accelerate it.
What if I can't cover all my minimum payments?
That's a cash-flow problem to fix first. Go back to Step 3 and free up surplus — starting with housing, transportation, and subscriptions.
What are the common mistakes?
Still charging on the cards you're paying down, closing paid-off cards (it can hurt your score), spreading extra payments across every debt, and treating a 0% balance transfer as "solved."
