How Much Money Do You Need to Start Investing?
Short answer: at most major brokers you can start investing with $0 to open an account and about $1 to buy your first fractional share. The barrier that used to exist is gone. The more useful question is not how little you can start with, but how much you need to invest effectively, so that fees, diversification and execution actually work in your favour. That number depends entirely on what you are investing in.
This guide walks through the real minimums by account type, the difference between a technical start and a productive one, where to put your first dollars, and how much you need to run a systematic crypto strategy properly. No hype, just the mechanics.

How much you can start with today
A decade ago, opening a brokerage account often required $1,000 to $3,000. Getting started meant saving up a lump sum first, and every trade came with a commission that made small orders uneconomic. That world is gone. In 2019 the major US brokers moved to zero commissions in quick succession, and over the following years most of them dropped account minimums to zero and added fractional shares.
The practical result is that the entry point is now measured in single dollars. You can open a standard brokerage account or an individual retirement account with nothing, fund it with any amount, and buy a slice of an S&P 500 fund or a high-priced stock for a few dollars. A $230 share can be bought in $1 pieces. Fractional buying is available at brokers such as Fidelity, Schwab, Robinhood and Vanguard, with per-order minimums that are usually between $1 and $5.
So the honest answer to "how much money do you need to start investing" is: very little to begin, but a steady habit to make it matter. Starting with $100 and adding to it consistently beats waiting until you have $10,000 sitting in cash. For a beginner, the amount of time your money spends invested does far more work than the size of the first deposit.
Minimums by account type
"Minimum" means different things depending on the account and the product inside it. Opening the account is one number. Buying a specific fund inside it can be another. Here is the current picture for common US options.
| Account or product | Typical minimum | Notes |
|---|---|---|
| Standard brokerage / IRA | $0 | Open with nothing, fund with any amount. |
| Fractional shares | $1 to $5 | Buy a slice of a share instead of the full price. |
| Index ETFs | $1 to 1 share | No fund minimum beyond the share price, or $1 with fractional. |
| Index mutual funds | $0 to $3,000 | Some are $0 or $1, others still require $500 to $3,000. |
| Robo-advisors | $0 to $1,000 | Managed, hands-off. Minimum varies by provider. |
| Margin account | $2,000 | A FINRA rule, not a broker choice. Only if you borrow to invest. |
Standard brokerage and retirement accounts. These are the base layer, and at most large brokers they cost nothing to open and carry no ongoing balance requirement. For plain stock and ETF investing, the minimum is effectively whatever you decide to deposit.
Mutual funds are the exception that still trips people up. Even inside a $0-minimum brokerage, a specific mutual fund can carry its own minimum, often $500 to $3,000. There is usually a simple workaround: the ETF version of the same index has no minimum beyond the share price, and can be bought fractionally. If a fund's minimum is higher than you want to commit, the equivalent ETF is normally the answer.
Robo-advisors hand the day-to-day management to an algorithm for an annual fee, typically a fraction of a percent. Their minimums range from $0 to around $1,000 depending on the provider. They suit people who want a diversified, hands-off portfolio and are willing to pay a small fee for it.
Margin accounts let you borrow against your holdings to invest more than you deposited. US regulation requires a minimum equity of $2,000 to maintain one. Margin amplifies both gains and losses, so it is not a beginner's starting point and is out of scope for most people asking this question.
The gap between "can start" and "should start"
Being able to start with $1 does not mean $1 will do much. Three things separate a technical start from a productive one.
Diversification. A single fractional share is not a portfolio. Broad exposure, through an index fund or a diversified strategy, is what smooths out the ride when any one holding falls. The good news is that even very small balances can buy a diversified fund, which is why index products are the usual on-ramp.
Costs relative to size. Flat fees, bid-ask spreads and minimum order sizes matter far more when the balance is tiny. A fixed cost is trivial on $5,000 and painful on $50. This is the core reason a product or strategy carries a minimum: below it, the mechanics stop working cleanly and costs eat a disproportionate share of returns.
Meaningful compounding. Growth is proportional to the balance. As an illustration, and not a prediction, US large-cap stocks have returned roughly 10% a year on average over the long run before inflation. At an average like that, adding $200 a month for twenty years would contribute $48,000 of your own money, and compounding would be expected to grow it to well beyond that over time. Past averages are not a promise of future results, and any single year can be sharply negative. The point is the mechanism: the early habit of adding regularly is what turns a small start into a balance where returns are worth noticing.
Where to put it: account types and order of priority
How much you need is only half the question. Where you put the money changes how much of your return you keep. A common order of priority for US investors looks like this.
1. Employer 401(k) match first. If your employer matches contributions, that match is an immediate return on the money you put in, before any market movement. Contributing at least enough to capture the full match is usually the first move.
2. Roth IRA. A Roth individual retirement account is funded with after-tax money and grows tax-free, which makes it a strong second stop. Most brokers open one with $0 and the same fractional-share access as a taxable account. The 2026 contribution limit is $7,000, or $8,000 if you are 50 or older, so even small regular deposits keep you well within bounds.
3. Back to the 401(k), up to the annual limit, if you want to invest more in tax-advantaged space.
4. Taxable brokerage account. Once tax-advantaged accounts are handled, a standard brokerage account has no contribution limit and no waiting period to access your money. You owe tax on gains in the year you sell, but broad index funds are relatively tax-efficient. This is also the account most people use for anything outside traditional retirement investing, including crypto.
None of these require a large starting balance. They differ in tax treatment and access, not in how much it takes to begin.
How much to start investing in crypto
Buying a bit of Bitcoin or Ether works the same way as buying a fractional share: you can start with a few dollars on most exchanges. Running a systematic strategy is a different problem. A strategy that rebalances a basket of assets, or trades a set of perpetual contracts on a schedule, needs enough capital to place each position at the exchange's minimum order size and to hold the intended mix without large rounding errors.
Every exchange enforces a minimum notional order size and a lot step, the smallest increment by which a position can change. On a large balance these are invisible. On a small balance they dominate. If a strategy wants to hold twenty positions but the balance only allows a handful to meet the minimum order size, the portfolio you actually hold is not the portfolio the strategy designed. That is why a well-built strategy states a minimum. It is not a marketing threshold. It is the point below which the exchange's mechanics start distorting what the strategy is trying to do.
This is also why "how much to start with in crypto" has two answers. For simply buying and holding, almost any amount works. For running a strategy correctly, the answer is the strategy's stated minimum, and starting below it means accepting worse execution.
Stoic minimums, now lower
We recently reworked how Stoic executes on several exchanges. The main change is a shift toward limit orders and other efficiency improvements, which reduce slippage and let the strategies build their positions more precisely. The upside for you is direct: strategies now execute accurately at smaller balances. As of today, the minimum for most strategies has dropped from $1,000 to $500.
| Exchange | Fixed Income | Stoic AI Crypto Index | Meta | BTC Yield | Trading cycle |
|---|---|---|---|---|---|
| Binance | $500 | $500 | $1,000 | $1,000 | Hourly |
| Binance.US | — | $500 | — | — | Once daily |
| Bybit | — | $500 | $500 | — | Hourly |
| Coinbase | — | $500 | — | — | Once daily |
| Crypto.com | — | $500 | — | — | Once daily |
| KuCoin | — | $500 | — | — | Hourly |
| Hyperliquid | — | — | $1,000 | — | Hourly |
The minimum is $500 for most strategies. The exceptions are $1,000: Meta on Binance and Hyperliquid, and BTC Yield on Binance. Meta on Bybit runs from $500. The Superforecaster strategy is not available in the app; it is offered through individual connection support, with a minimum of $5,000.
Stoic pricing is a subscription that scales with the size of the portfolio you connect, so a smaller start also means a smaller subscription. You keep custody of your funds on your own exchange account throughout; Stoic connects through the exchange and executes the strategy, it does not hold your money.
Why going below the minimum hurts results
These minimums are the floor for correct execution, not a suggestion. If your connected balance sits below the stated value, the strategy cannot place every position at the size it intends. Exchange minimum order sizes and lot steps force rounding, some positions get skipped entirely, and the portfolio you actually hold drifts away from the one the strategy designed.
The Meta strategy is the clearest example. It is market-neutral and trades a wide set of crypto perpetuals, more than forty of them, with each leg sized to a specific weight. On a $1,000 balance those legs can be built to size. Well below the minimum, several legs fall under the exchange's minimum order size and cannot be opened at all, so the intended balance between long and short exposure breaks. The strategy is no longer doing what it was built to do, and your results diverge from its intended behaviour. Starting at or above the minimum is what keeps execution accurate and keeps your outcome in line with the strategy's design.
Common mistakes when starting small
Waiting for a "big enough" amount. The most expensive mistake is not starting. Time in the market is the one input you cannot buy back later.
Over-trading a tiny balance. Frequent manual trades on a small account let spreads and fees quietly erode returns. Small balances reward patience and low turnover.
Ignoring the product's minimum. Running a strategy below its stated minimum feels like a clever shortcut and produces worse, harder-to-explain results. If you cannot meet a strategy's minimum, choose one whose minimum you can meet rather than under-funding it.
Confusing volatility with risk of ruin. Prices move, especially in crypto. The amount you commit should be money you can leave invested through a drawdown without being forced to sell at the wrong time.
A simple way to decide your number
Work from three questions rather than a single figure.
What are you investing in? Plain index investing can start at almost any amount. A systematic strategy should start at or above its stated minimum so it executes cleanly.
Can you add to it regularly? A modest start plus consistent contributions usually beats a larger one-off deposit you never build on. Automating a small monthly amount is often more effective than trying to time a lump sum.
Is it money you can leave invested? Markets move. The amount you commit should be capital you will not need to pull out at a bad moment. Nothing here is a promise of returns, and crypto in particular is volatile.
Answer those three and the right starting number tends to become obvious: enough to be diversified, enough to clear the minimum of whatever you are using, and no more than you can leave alone.
FAQ
How much money do you need to start investing?
At most major US brokers, $0 to open an account and about $1 to buy a fractional share. For plain stock and ETF investing there is effectively no minimum. Specific products, such as some mutual funds or managed robo-advisors, may require $500 to $3,000.
Can I start investing with $100?
Yes. $100 is enough to buy fractional shares of a diversified index fund at a $0-minimum broker. The bigger lever at this size is adding to it regularly rather than the starting amount itself.
Is it worth investing small amounts of money?
Yes, mainly because of time and habit. Small, regular contributions compound, and starting early matters more for a beginner than the size of the first deposit. The key is keeping costs low relative to the balance.
Where should a beginner put their first money?
A common order is: capture any employer 401(k) match first, then a Roth IRA, then more 401(k) if you want, then a taxable brokerage account. Each opens with little or nothing; they differ in tax treatment and access, not in the amount needed to start.
What is the minimum to start investing with Stoic?
$500 for most strategies. The exceptions are $1,000: Meta on Binance and Hyperliquid, and BTC Yield on Binance. Meta on Bybit starts at $500.
Why did Stoic lower its minimum from $1,000 to $500?
We improved execution on several exchanges, including a shift toward limit orders and other efficiency work. That lets the strategies execute accurately at smaller balances, so we lowered the minimum for most strategies from $1,000 to $500.
What happens if my balance is below the strategy minimum?
Execution accuracy drops. Exchange minimum order sizes and lot steps force rounding, some positions may be skipped, and the portfolio you hold drifts from the strategy's design. Starting at or above the minimum keeps execution accurate.
How much do I need for the Meta strategy?
$1,000 on Binance and Hyperliquid, and $500 on Bybit. Meta trades a wide set of perpetual contracts, so each position needs enough capital to be sized correctly.
Do I need $5,000 for Superforecaster?
Superforecaster is not available in the app. It is offered through individual connection support, with a minimum of $5,000.
Is a larger starting balance always better?
Not necessarily. Above the minimum for correct execution, what matters more is choosing a strategy that fits your goals and adding to your balance consistently over time.
