Should you pay down debt or invest? The original version of this article, from 2014, said the answer comes down to rates, and that is still the right frame. What has changed is the rates. Credit card interest is far higher than it was, safe savings finally pay something real, and the retirement-match rules make one particular dollar worth more than any other. Here is the 2026 version of the game, with the numbers filled in.

The rates on the board

Every debt you hold is a guaranteed return waiting to be collected: pay off a balance at 22% and you have earned 22%, risk-free and tax-free. Every investment is a hoped-for return. Line them up:

  • Credit cards: 22.15% average APR on accounts that carry a balance as of the second quarter of 2026, with many new offers above 25% and store cards averaging over 31% in the CFPB’s 2024 data.
  • Personal loans: about 13.4% for a three-year loan in 2026, plus origination fees of 1% to 8%.
  • Auto loans: 6.35% average for new cars and 11.19% for used in mid-2026, per Experian.
  • Federal student loans: 6.52% for undergraduate Direct loans disbursed in 2026-27; 9.07% for Parent PLUS.
  • Mortgages: mid-6s for a 30-year fixed through 2026; HELOCs around 7.25%.
  • Stocks: roughly 10% a year compounded over the last century before inflation, per NYU Stern professor Aswath Damodaran’s data. That is a long-run average, not a promise; individual years swing wildly in both directions.
  • Cash: about 4% APY in the best high-yield savings accounts and 4.3% to 4.5% in top CDs in 2026, while many big-bank savings accounts still pay under 1%.

The old rule of thumb assumed a narrower gap between what cards charge and what markets return, and a cash yield of essentially zero. Neither assumption holds in 2026, and the order of operations below follows from that.

Step 1: Take the full 401(k) match

If your employer matches contributions, the match is the highest return available to you anywhere, and it beats paying off any debt. A dollar-for-dollar match is an instant 100% return on the matched dollars; a 50-cent match is an instant 50% return. No card charges that much. Contribute enough to capture every matching dollar before you do anything else, even while carrying card debt. The 2026 contribution ceilings are in our guide to this year’s limits.

Step 2: Kill anything above 20%

Card debt is the emergency. At 22.15%, a $3,500 balance costs about $64.60 a month in interest alone; a $10,000 balance at 22% paid at $250 a month takes about six years to clear and costs roughly $8,200 in interest. No realistic investment return beats a guaranteed 22%, and the stock market’s long-run 10% is not guaranteed at all. Every dollar beyond the 401(k) match goes here until the balance is gone. The payoff order, the balance-transfer math and the hardship options are laid out in our credit card escape plan for 2026.

Step 3: Build the emergency fund, in an account that pays

Once the 20%-plus debt is gone, build a cash cushion before investing further. This used to feel like a sacrifice because savings paid nothing. In 2026 a high-yield savings account pays about 4%, so the cushion earns a real, insured return while it waits. How much you really need, and where to keep it, is covered separately. The short version: enough that a job loss or a car repair does not send you back to the card.

Step 4: The middle debts are a judgment call

Personal loans near 13%, used-car loans near 11%, Parent PLUS loans at 9%: these sit well above what cash pays and near or above what stocks have delivered on average. Paying them down is a strong, guaranteed return, and the general rule is to attack anything in the double digits before investing beyond the match. For debt between roughly 6% and 9%, the math is close and the tie-breakers are personal: how secure your income is, how much the debt bothers you, and whether the interest is tax-deductible (mortgage interest is, but only if you itemize).

Step 5: Invest ahead of the cheap debt

A mortgage in the mid-6s, a new-car loan in the mid-6s, an undergraduate student loan at 6.52%: these are the debts you can reasonably carry while you invest. The expected return from a diversified stock portfolio over decades is higher, tax-advantaged accounts amplify the difference, and compounding only works if the money goes in early. Prepaying a 6.5% mortgage is a fine use of surplus, but not before the retirement accounts are funded. Two tests: if a debt’s rate is below what a high-yield savings account pays, never prepay it, because cash beats it risk-free. If it is above cash but below the long-run stock return, invest first and prepay with what is left.

Can you do both?

Yes, and most people should. The order above is about priority, not exclusivity: the match always comes first, the 20%-plus debt gets every spare dollar until it is gone, and after that you can split the surplus between prepaying middle-rate debt and investing in whatever proportion lets you sleep. The only real mistake is the one the original article warned against: investing at a hoped-for 10% while paying a guaranteed 22%.
