I became a CPA in 1981, spent a decade on Wall Street, and I’ve been writing about money ever since.
In all that time, the mistake that’s bugged me most isn’t overspending or picking bad investments. It’s watching people walk right past cash that’s theirs for the taking.
So here are the five best sources of free money out there, ranked by how much they’re worth. Grab them in order.
1. Your employer’s 401(k) match
This one’s first because nothing else comes close. If your employer matches your contributions, that’s an instant 50% to 100% return on your money. No investment on earth reliably does that.
And people skip it anyway.
A landmark study by the Society for Human Resource Management found that one in four workers fails to grab their full match. The average miss? About $1,336 a year. Collectively, Americans leave roughly $24 billion on the table annually.
Log in to your plan today. Find out what your employer matches, then contribute at least enough to capture every dollar. If you want the full math on what skipping it really costs, I’ve laid it out. It’s ugly.
2. The health savings account triple play
An HSA is the only account I know that’s tax-free coming and going. Your contributions go in pre-tax, the money grows tax-free, and withdrawals for medical costs are tax-free too. That’s three tax breaks in one account.
Here’s the free-money part. Many employers seed your HSA with a few hundred dollars just for having one. That’s cash you didn’t earn, sitting there waiting.
For 2026, the IRS lets you contribute up to $4,400 with self-only coverage or $8,750 for a family. If you’re 55 or older, you can add another $1,000. You’ll need a qualifying high-deductible health plan to play.
In fact, I’d argue it’s the best retirement account out there — money you park young can compound tax-free for decades.
3. Bank and brokerage sign-up bonuses
Banks and brokerages hand out real cash to win your business. Open an account, meet the terms, and they’ll drop a bonus straight into your balance. I’ve seen offers run from $100 to several hundred dollars.
The catch isn’t a catch — it’s fine print. Read it.
Most bonuses require a direct deposit, a minimum balance, or that you leave the money parked for a few months. Meet the conditions, collect the cash, and don’t let the account start charging fees once the bonus clears.

4. Money you’re already owed
Some free money isn’t a reward. It’s just yours, and you’ve lost track of it.
Roughly one in seven Americans has unclaimed property sitting with a state — an old paycheck, a forgotten deposit, an insurance payout. State programs returned about $4.49 billion to people in a single year, according to the National Association of Unclaimed Property Administrators.
Start at MissingMoney.com or your state’s official site. It’s free to search, and it takes just minutes.
While you’re at it, hunt down any old retirement accounts. Here’s how to find a lost or forgotten 401(k), plus other freebies the government already owes you.
5. The interest your bank isn’t paying you
This one’s technically opportunity cost, but the effect is the same — money you could have for zero effort, going uncollected.
The FDIC pegs the national average savings rate at just 0.38% as of June. The biggest banks are stingier still, paying as little as 0.01%. Meanwhile, online banks are handing out close to 4% or more on the exact same federally insured dollars.
Park $10,000 at 0.01% and you earn a dollar a year. Move it to 4% and you earn $400. Same money, same safety, 400 times the return. The only thing between you and that cash is an afternoon of paperwork.
One example: SoFi offers a combined checking-and-savings account with no account fees. With eligible direct deposit or $5,000+ in qualifying deposits every 31 days, you can earn a competitive APY on savings — many times the national average — plus interest on checking. New members may also qualify for a limited-time APY boost for up to six months. (APYs are variable and can change at any time.)
New members who set up qualifying direct deposit may also be eligible for a cash bonus of up to $400, based on the amount deposited. Terms apply — see details.
Earn up to 4.40% Annual Percentage Yield (APY) on one SoFi Savings account with a 1.10% APY Boost (added to the 3.30% APY as of 10/20/26) for up to 6 months. Open your first SoFi Checking and Savings account between 10/20/26 and 12/31/27, then within 60 days of account opening receive an eligible direct deposit OR $5,000 or more in qualifying deposits. You must maintain eligible direct deposit or $5,000 in qualifying deposits every 31 days to keep the Boost, for up to 6 months. Rates variable, subject to change.
Terms apply at sofi.com/banking. SoFi Bank, N.A. Member FDIC.
And the interest is just the start — a fat savings balance gives you a cash cushion that helps you pay your bills on time, which lowers your insurance premiums, your loan rates, and your stress.
Bottom line? None of this takes a finance degree. It just takes a little attention. Go through this list in order, and you’ll pocket more free money this year than most people see in a decade.
