Keep some cash, then let the interest rate decide

You have some money saved and a debt you want gone. Using the savings to clear it would feel like relief; keeping them feels like safety. People split on this, and what decides it comes down to two numbers you can look up, one question only you can answer, and how much risk you’re willing to carry. If you can’t make the minimum payments, or a debt is already with a collector, start with the section at the end instead.

Keep some cash whatever you decide, then let two things settle the rest: how high the debt’s interest rate is, and how steady your income is.

How people weigh it, in short:

• A high-rate card and steady pay: the people who argue it say this usually favours a small cushion, with the rest going on the card.
• A low-rate loan, or pay that could stop: they say this might favour a bigger cushion first.
• A job that matches retirement savings: one person pointed out that the match comes before either — it is money added the day you contribute.
• You can’t make the minimums: the section at the end is for you.

Two numbers and one question

The first number is the interest rate on the debt. The second is what your savings earn. Some people say high-interest debt, credit cards above all, should generally be paid before you build large savings, because interest you stop paying is a guaranteed return that savings rarely match, and some add that lower-interest debt can wait. One person’s rule of thumb: at around 6 percent or less, keep the savings and pay the minimum; at a rate like 19 percent, paying it off is urgent. Another thought a loan at close to 0 percent may be worth keeping while the cash sits in the bank. This advice comes from 2011 to 2020, when savings accounts paid around 1 percent. Rates on both sides have moved since, which is why this page gives you the comparison and not the answer.

Two things to check before you compare. One person pointed out that a car loan is not always the cheap one: with poor credit, car loan rates can run to 10 percent or more. And a tax deduction on loan interest gives back only your tax rate’s share of that interest, so it never makes a loan free and rarely justifies keeping one you could clear.

The question is how steady your income is. One way people weigh it is job security: with stable jobs and a reliable car, pay down the debt; if things are shaky, keep cash. They disagree about what two incomes mean. One person says a household with two incomes is less likely to collapse if one job goes, so it can put more toward the debt. Another says two incomes mean more chances that one of them stops, and that looking for work itself costs money, for travel, clothes and certifications. Both are describing the same household from different ends. In the United States, federal job-protected leave does not cover every worker, for example at small employers, and the US Department of Labor says the leave it does give is unpaid, so a health problem can also be an income problem.

If your job matches retirement contributions, one person’s correction comes before either number: take the match first, because it is money added the day you contribute, whatever the loan’s rate. That money is for retirement, not an emergency fund. The page here called Take the match first has the rest.

Keep some cash whichever way you go

Some people advise keeping a small starter fund before attacking debt, so that the next car repair or medical bill doesn’t land straight on a card. One person’s version is to make sure food, transport and housing are covered first; another suggests keeping at least enough to meet your health insurance deductible. The dollar figures people used, a thousand or two, are years old, so size yours by what a common emergency would cost you now. One person’s middle way is to split the cash: about half onto the debt, the higher-rate one first, and the other half kept as the buffer.

People who argue for the cushion explain why it matters more than the interest it costs. Without it, one person says, a small shock can cascade; another, that a repair you can’t cover goes onto a card, the expensive debt you were trying to escape. A third says the cash does a job the arithmetic misses: it prevents the stress, and the slide back into borrowing, that a crisis brings. In one case people discussed, putting the savings on the debt would have saved about $25 a month in interest, small enough that keeping the cash looked reasonable; the real rates were never given, so treat that as an illustration.

One person’s step isn’t a number at all: agree in writing, in advance, what you would cut and what you would sell if the income stopped. A plan made before the crisis saves arguing during it. Another points out that the fund is there to cover necessary costs, not to replace a wage. Others suggest splitting the cushion by how fast you might need it: some in instant-access checking, some in savings a day or two away, and the rest somewhere slower. The page here called Move the money that’s just sitting there is about where that cash can sit.

A credit limit is not a cushion

People who count an unused credit card or a line of credit as their emergency fund have a case: one argued that paying all the cash into high-interest debt, and borrowing for a crisis later, ends in the same place and saves interest in between. Others answer that the maths only works if the credit is still there when you need it. People warn that banks can lower or cancel a limit when your income changes, which is exactly when you would reach for it, and others say theirs was cut after they paid the debt off. The warning is plain: don’t rely on cards as your only emergency money unless you can pay the balance in full each month.

One person’s route was to refinance a home and pay off the cards with it. The warnings people raised are real: it needs genuine equity, it is risky if property values fall, and it fails if the cards fill up again. They miss one more: this puts the card debt on your house, so falling behind puts the home at risk.

If you pay extra, make sure it lands

People warn that an extra payment doesn’t always reduce what you owe. Some loan servicers apply it to your next due dates instead of the balance, so you have simply paid next month early and the loan runs just as long. One person’s fix is to make the extra payment separately, by hand, rather than through the automatic one; another’s is to check the next statement and see whether the principal went down. One person found that even choosing the option not to move the due date left part of the extra going to interest, and never got a clear answer from the servicer. Keep checking.

If you have more than one debt, one person swears by paying the smallest balance first, for the lift of watching debts disappear; others say the highest rate first saves the most, if you can keep your spending in check. What decides it, they say, is whether you need quick wins to keep going. Whether a loan can be paused in a crisis depends on the loan and its rules, so ask the lender before you count on it. And some people warn that paying off a loan can dip your credit score, because an account closes or your total available credit shrinks. That is about a loan that closes; it is not a reason to stop paying down a card, and the page here called Pay the card off and keep it open is about that.

If you’ve just paid off the last debt and are asking what now, some people say keep sending the old payment somewhere, into savings or investments, before it quietly turns into spending. Past that, people split between saving or investing it and enjoying some of it. The pages on taking the match and on idle cash are written for you.

Who this page is not for

If you can’t make the minimum payments, or a debt has already gone to a collector, the question on this page is not your question yet. Start with a nonprofit credit counselor, and if the debt is a card, with the page about calling your card company for a lower rate.

And outside the United States, the account names on this page won’t match yours, but the comparison does: what the debt costs, what the savings earn, and how steady the money coming in is.

Debt is paid down by months of payments, and a cushion is what keeps a bad week from undoing them.
