Attack expensive debt first

“Expensive debt” means any balance with an interest rate high enough that, over a year, the interest charge is a meaningful share of the balance. Credit cards, store cards, and most unsecured personal loans qualify. A 20% APR on a credit-card balance is a guaranteed −20% return on the cash sitting in that balance. Paying it off is the same as earning 20% risk-free. There is no investment a regular person can access that beats it with less effort.

Why “expensive first” is the rule

The reason to attack expensive debt before doing anything else is mechanical. If you have two balances — a credit card at 22% APR and a 0% promotional loan — the financially correct move is to put every spare dollar against the credit card first. The 22% you avoid paying is the same as a 22% risk-free return on the cash you would otherwise have kept.

The list of returns this beats is long:

High-yield savings accounts: ~3–5%.
Long-term index investing: ~5–8% expected, with year-to-year variance.
Real estate, bonds, gold, crypto: each carries risk, fees, and illiquidity.

There is one exception, and it is narrow. If a balance is on a 0% promotional rate that expires in the next 3–6 months, and you cannot pay it off before it expires, that balance is temporarily not the priority — but it becomes the priority the day the promotion ends. Plan for that day now, not when the bill arrives.

Avalanche vs snowball — which order is right?

The “which balance first” debate has two serious answers and a long tail of bad ones. The two serious answers are:

Avalanche. Pay the minimum on every balance, then throw every spare dollar at the balance with the highest interest rate. Total interest paid is minimised. The mathematically optimal answer.
Snowball. Pay the minimum on every balance, then throw every spare dollar at the balance with the smallest total balance. Total interest paid is slightly higher. The psychologically easier answer.

For most people, the avalanche method saves the most money. The argument for snowball is real but narrow: if you have tried and failed to make debt payoff stick, the early win of clearing a small balance produces the momentum that avalanche does not. The right method is the one you will actually run for 18 months.

Method	Strength	Weakness	Total interest paid	Best for
Avalanche	Mathematically optimal	Slow first win	Lowest	People with steady income and one or two balances
Snowball	Early psychological wins	Slightly higher interest	Slightly higher	People with 4+ balances who need momentum

A practical variant: list every balance with its rate and its balance. Mark the highest-rate balance as the primary target. Mark the smallest balance as a “fast win” — once the smallest balance is gone, redirect that payment to the primary target. You get the snowball win without abandoning the avalanche math.

Don’t close paid-off credit cards

Once a credit-card balance is at zero, the instinct is to close the card. Don’t. Closing the oldest card raises your credit utilisation ratio (the share of your total credit limit that you are using), which lowers your credit score. A lower score costs you more on every future loan — mortgage, car, personal — for years.

The right move is to keep the card open, store it somewhere safe, and use it once a year for a small recurring subscription so the issuer does not close it for inactivity. The credit-card balance is gone; the credit history is the asset.

There is one exception. If the card has an annual fee and you cannot get it waived, closing it is fine — the math favours the fee savings over the marginal credit-score impact.

The minimum-payment trap

The single most important number on a credit-card statement is the minimum payment. It is also the most misleading. The minimum is set to be affordable this month, not to make a dent in the balance. A $5,000 balance at 24% APR with a 2% minimum payment takes 30+ years to clear and pays more in interest than the original balance.

Three rules that break the trap:

Set your own payment. A fixed amount above the minimum, ideally 3–5x it, and ideally the same as your old “spending” budget line — the money used to be spent, now it services the debt.
Pay weekly, not monthly. The interest on a credit-card balance compounds daily. A payment mid-cycle reduces the average daily balance, which reduces the next month’s interest. The difference is small per month, large over a year.
Cap the balance, not the payment. If a card charges 24% APR, the rational use of the card is to never carry a balance. Treat the card as a 30-day float. If the balance does not clear every month, the card is being used as a loan at 24% — which is the debt you are trying to escape.

Negotiation is real

Most people do not negotiate credit-card rates because they assume the answer is no. The answer is more often yes than you think. The mechanics:

Call the number on the back of the card.
Say: “I have been a customer for X years. I am considering a balance transfer to a card with a 0% promotional rate. Can you match that?”
If they say no, ask to be transferred to the retention department. Their job is to keep you.
If they offer a rate reduction, ask for it in writing and for the new rate to apply to the existing balance, not just future purchases.

It works. The success rate on a single call is high enough to be worth an hour of your afternoon. If the rate reduction is meaningful — say, from 24% to 14% — the savings on a $5,000 balance is $500 per year, every year, for the life of the balance. A second call in six months with a competitor’s offer is also fine.

Balance-transfer offers are the other real lever. Many cards offer 0% on balance transfers for 12–18 months for a 3–5% transfer fee. The fee is worth it if the alternative is paying 22% APR. The discipline is to clear the balance before the promotion expires — otherwise the rate snaps back to the standard APR, and the discount is paid back as interest.

How does debt fit into a budget?

Expensive debt is a line item in the 50/30/20 check, but it should not live in the same column as your savings. The cleanest framing is:

Needs (50%). Includes the minimum payment on every debt.
Savings/debt (20%). Includes the extra payment on the target balance, on top of the minimum.

That way, the budget is honest: the minimums are a fixed cost, and the extra payment is the discretionary line that actually moves the needle. The 20% line is shared between savings and debt-paydown until the debt is gone — at which point the full 20% flows to building the calm buffer and then to long-term investing.

Where Finanxy fits

Finanxy models every debt as a liability account with a negative balance and every payment as a transfer between accounts. The interest portion of a payment shows up as an expense, the principal portion shows up as a balance reduction — exactly the way an accountant would model it. The monthly report shows how much of every payment went to interest versus principal, and what the effective interest rate was on each balance.

The tagging flow supports a “debt payoff” tag for the extra payment line, separate from the minimum payment that lives under the credit-card account. The two are reported differently, which makes it easy to see whether the avalanche is actually working — or whether the payments are quietly being absorbed back into the balance.
