The search bar assumes you have more money than you do. You have fifty dollars. Or a hundred. Or five hundred, sitting in a checking account that pays almost nothing. The question as you actually ask it is not “where should I invest.” It is: can I start investing with $50? With $100? Does the $500 count?
I worked twelve years on the floor of bank branches, and that was the question I heard more than any other. Not which stock, not which fund. Where does the small number go?
The short answer, for 2026, is yes to all three. And the rest of this article counts it: the account minimums and fees as of September 28, 2026, platform by platform; the first purchase, costed to the cent; what the number becomes over thirty years at the dated return; and where the next $500 goes.
The $50, the $100, the $500
You do not wait for enough. That is the trap, and it has a mechanism: every answer you have seen assumes a starting point you do not have, so the answer never fits, so the money waits, and the waiting costs more than the number could ever have made.
The two hundred dollars is a real number. So is the fifty. A real number is any number that is actually in your account, as of this week. The size of it does not change what investing is. It only changes the scale.
So here is the 2026 scale, counted. Not the scale a listicle wrote in 2019. The dated one.
The 2026 account table, dated
This is the table the question is actually about. What an account costs to open and to use, as of September 28, 2026, named per platform.
| Platform (2026) | Account minimum, Sept 28, 2026 | Cost of the first purchase | Source, dated |
|---|---|---|---|
| Charles Schwab (Schwab Account, IRA) | $0; no opening or maintenance fee | $0 online US stocks and ETFs; $0 on OneSource mutual funds; $0.65 per options contract | Schwab Pricing Guide, April 2026 |
| E*TRADE from Morgan Stanley | $0 (fund within 30 days) | $0 online US-listed stocks, ETFs, mutual funds and options | E*TRADE account page, 2026 |
| Fidelity | $0; no account fees | $0 US stocks, ETFs and options ($0.65 per contract); no-transaction-fee mutual funds; $1 entry to most of its own funds | Fidelity, 2026 |
| Robinhood | $0 ($1 for the fractional share; $2,000 for margin) | $0 stocks, ETFs, options, crypto; no mutual funds; Gold is optional at $5/month | Robinhood, 2026 |
| Webull | $0 | $0 US stocks and ETFs; fractional shares | Webull fees page, Sept 28, 2026 |
| SoFi Invest | $0 ($1 for automated investing) | $0 stocks and ETFs; $5 fractional; $0 automated-investing fee | SoFi, 2026 |
| Vanguard (online brokerage) | $5,000 | $0 US stocks, ETFs and mutual funds | Vanguard account page, Sept 28, 2026 |
| Acorns (micro-investing app) | $5 | $3 to $12 a month, by plan | Acorns, 2026 |
Read the minimums first. Seven of the eight rows open at $0. The $500 clears every one of them, and so do the $100 and the $50, through the fractional share, which is the part of the table that changed the answer. Before the fractional share, a $50 reader could not buy a share priced above $50; now the purchase is by the dollar, not by the share.
Then read the one row that still gates. The Vanguard online brokerage account wants $5,000 before it opens, and it is the only true gate left in the 2026 table. That is a fact about one platform, not a fact about investing.
Read the fee rows second, because the minimum is only half of “where the money goes.” The commission is $0 in 2026 across the table for the first purchase of a US stock or ETF, and the fee that remains is not in this table at all. It is in the fund. The index fund the first purchase goes into costs 0.03% a year in the 2026 fund data this site runs on — the figure counted fund by fund in the index fund vs ETF comparison.
One fee the table does show, because a small account should see it: the transfer-out. Moving the account somewhere else is an ACATS transfer — the formal name for the move — and it is $75 at Robinhood and $75 at SoFi as of 2026. On a $500 account, a $75 exit is a sixteenth of the money. The no-minimum door opens both ways, and the small account should price it.
Two more dated notes, so the table is honest. E*TRADE’s $0 account must be funded within 30 days to stay open. And the last row is the app tier: no commission, but a monthly fee instead, $3 to $12 a month. On $500, a $3 monthly fee is 0.72% a year, twenty-four times the fund’s fee. The monthly fee is the one number in 2026 that still taxes the small account.
The first purchase, counted
Here is the purchase, end to end. This is the part the checking account was waiting for.
You open the account. Any no-minimum row in the table works for the $500. The opening costs $0 and the monthly fee is $0 at every one of them.
You buy the index fund. One fund, the total market or the S&P 500 — the 0.03% fund from the 2026 data above. You do not pick a stock, and you do not pick a manager. You buy $500 of the index, and the fractional share is what makes that possible: the purchase is $500 by the dollar, whatever the share price is on the day.
Now the count, because “the cost” is the number the question keeps asking for.
- Commission on the purchase: $0 (the 2026 fee row, every no-minimum platform).
- The fund’s fee on the $500: 0.03% of $500 is $0.15 a year.
- Total cost of the first purchase, in 2026: $0.15.
That is the whole fee. Fifteen cents a year on the $500, one cent and a half on the $100, and a little over a cent on the $50. The index fund makes the small number count — including the fee, which is now small in the same way.
What the $500 holds after the purchase is a slice of the index. No name, no manager, no story to follow. The first contribution is the whole point, and the first contribution is done.

What the $500 becomes in thirty years
The trace. The dated set this site runs on, from the long-run record of the US equity market since 1926: about 9.8% a year with dividends, 6% after inflation, as the center case — and 3% real as the planning floor, the end of the range the plan should survive. The record is dated, and it is the same dated set the site counted on in the wrapper comparison and the 3-fund build.
One hundred dollars, five hundred, fifty — invested once, no contributions added, thirty years, the fee deducted from growth the way a fee works:
| Starting, Sept 2026 | After 30 years, 6% real | Fee over the 30 years | After 30 years, 3% real | Fee over the 30 years |
|---|---|---|---|---|
| $50 | $287 | $2 | $121 | $1 |
| $100 | $574 | $5 | $243 | $2 |
| $500 | $2,872 | $24 | $1,214 | $11 |
The fee column is the one to read. The fund’s 0.03% over thirty years costs $2 on the $50 and $24 on the $500. The fee compounds, yes — the same way the money does, against you — but on a first contribution, it compounds from a rounding error.
The honest note, dated too: the same record that averages 6% after inflation has years where the index falls more than 30%. The $2,872 is what thirty years of the record does to $500, not a promise, and that is why the table carries the 3% floor as a column of its own. At the floor, the $500 is $1,214. Still five times what the checking account paid it. Still a real number, doing the one job a checking account cannot do.

This is not a retirement plan, and it is not an allocation. It is what the first contribution becomes when it is not stopped at the door. The allocation and the retirement number are the next lanes, and they get their own articles on this site.
The next $500
The $500 that comes after this one has an order, and the order is the site’s sequence, not a preference.
The spend plan first. Then the emergency fund, sized and counted here, because the small account that gets spent on the first broken thing is not an account at all. If you carry debt at the card’s rate, the next $500 goes there before it goes here — the debt lane does the paying in that article, and this lane only names the order.
Then the next $500 goes back into the same fund, and the best version of it is the automatic one: the contribution set on payday, before the money is spendable. The automatic first dollar is the whole point of the sequence, because the decision stops being a decision.
When the first contribution becomes a habit, the room is the 2026 limit: $7,500 to an IRA, $24,500 to a 401(k), each from the IRS notice dated November 13, 2025 — every 2026 limit in one table here, with the Canadian room beside it, the $7,000 TFSA and the $33,810 RRSP cap. Which vehicle takes the money is a different question with its own answer: the 401(k) vs. Roth IRA, counted at three 2026 incomes. This article does not pick; it gets the $500 invested first.
You do not wait for enough. You start with what is real — the fifty, the hundred, the five hundred — and the index fund makes the small number count.
The first contribution, made. The small number is now a real, compounding number.
