The number one reason women say they don't invest is not having enough money. According to research from Ellevest and others, around 35% of women cite this as the blocker. The good news is it's almost entirely a knowledge gap, not a money gap. You can open a retirement account today with $1 and start building wealth this month.
The minimum to open an investment account is $1
The biggest US brokerages all have $0 account minimums and support fractional shares — meaning you can buy a slice of any stock or fund for as little as $1, instead of paying for one whole share.
- Fidelity — $0 minimum, fractional shares from $1, no account fees. Strong default for a first Roth IRA.
- Charles Schwab — $0 minimum, fractional shares from $5, no fees. Good if you might want a checking account in the same place.
- Vanguard — $0 minimum to open, $1 minimum for many index funds. The original low-cost index fund provider; great long-term home.
All three are SIPC-insured (your money is protected up to $500,000 if the brokerage fails) and free to use. Pick one and move on — the difference between them matters far less than actually starting.
Where to put your first $50
One broad index fund. That's it. A broad index fund holds hundreds or thousands of companies at once, which means you're not betting on any single stock going up — you're betting on the US (or global) economy growing over decades, which it historically has, by about 7% per year on average after inflation.
The two most common picks:
- S&P 500 index fund — tracks the 500 largest US companies. Tickers: FXAIX (Fidelity), VOO (Vanguard ETF), SWPPX (Schwab).
- Total US stock market fund — like the S&P 500 but includes thousands of smaller companies too. Tickers: FZROX (Fidelity, zero-fee), VTI (Vanguard ETF), SWTSX (Schwab).
For your first $50, either one is fine. Don't agonize over which — the long-term returns are nearly identical.
Why not individual stocks, crypto, or "hot tips"
Picking individual winners is hard. Most professional fund managers underperform a plain S&P 500 index fund over any 10-year period — so the realistic odds of you doing better by stock-picking your first $50 are low. Crypto is volatile in a way that's emotionally hard to hold through when you're new. Start with the boring, statistically winning option. Get bored if you must. Boring works.
What $25/month actually becomes
The whole reason starting small still works is compounding. Each year, your returns earn returns of their own. Over decades, that snowballs in a way that's hard to intuit until you see it.
Here's what $25/month becomes at a historical-average 7% annual return, depending on when you start:
| Start age | Monthly | Total contributed by 65 | Value at 65 |
|---|---|---|---|
| 25 | $25 | $12,000 | ~$66,000 |
| 35 | $25 | $9,000 | ~$30,000 |
| 45 | $25 | $6,000 | ~$13,000 |
The 25-year-old contributes only $3,000 more than the 45-year-old, but ends up with five times more. That's compounding doing the heavy lifting. The lesson: the cheapest way to invest more is to start earlier, not to find more money.
Bump $25 to $100/month and the 25-year-old's ending balance jumps to roughly $264,000. Bump to $250/month and it's about $660,000. The leverage is enormous and it costs you nothing except time.
The 3-step setup (do this once, then ignore it)
The whole point of this is to set it up and walk away. Trying to time the market or check your balance weekly is one of the fastest ways to lose money emotionally. Do this once:
- Open a Roth IRA at Fidelity (or Schwab, or Vanguard). Roth means you pay tax now and never again — withdrawals in retirement are tax-free. Takes about 15 minutes online. You'll need your Social Security number and a bank account to link.
- Set up an automatic monthly transfer from your checking account on the day after payday. $25, $50, whatever you can spare. Automating it removes the monthly decision — and the monthly decision is where good intentions die.
- Set the contributions to auto-invest into one index fund. FXAIX or FZROX at Fidelity. Done. Don't check it every day. Don't check it every week. Look at it once a year, increase the transfer by $10 when you get a raise, and otherwise leave it alone.
If your employer offers a 401(k) with matching, contribute at least enough to get the full match before funding the Roth IRA — the match is free money and usually a 50–100% instant return.
Common mistakes when starting small
The mistakes that quietly cost people the most aren't about picking the wrong fund. They're about behavior.
- Waiting for "enough money." The 35-year-old who waited 10 years to start lost roughly $36,000 of future value to that wait. Starting with $25 today beats starting with $500 a decade from now.
- Picking high-fee funds. A 1% annual fee sounds small but compounds away nearly a third of your long-term returns. Stick to broad index funds with expense ratios under 0.10%. The ones listed above all qualify.
- Panic-selling when the market drops. Markets drop 10–20% somewhere in the average year. Selling during a drop locks in the loss and means you miss the rebound. Your auto-transfer doesn't care — it just keeps buying at the lower price, which is exactly what you want.
- Stopping when life gets complicated. A bad month, a job change, a wedding, a baby. The temptation is to pause the transfer and "restart later." The transfer is small enough that you almost certainly don't need to — leave it running.
- Investing money you'll need in the next 2 years. Anything you'll spend soon (emergency fund, near-term savings) belongs in a high-yield savings account, not the market. Investing is for money you can leave alone for 5+ years.
A note for women specifically. Investing $25/month is the easy part. The harder, more important work is planning around career breaks, longer life expectancy, and the gender wealth gap — the structural reasons women end up with less even when they earn the same. Demi is built around exactly that. Coming soon: the FAQ covers this in more depth, and a dedicated guide on financial planning for women is on the way.
What to do this week
If you take one action from this guide, make it the Roth IRA. Open it tonight while you're thinking about it. Set the auto-transfer for $25 on the next payday. Pick FXAIX (or FZROX, or VTI). Close the tab.
That's the entire job. You don't need another book, another podcast, or another "best beginner stocks" listicle. You need fifteen minutes and an account.
