The short answer
Brokers will let you open an account with $100 or less. That is a marketing number, not a viable one. The real constraint is position sizing: if you risk a sensible 1% per trade, a $100 account risks $1 per trade — and the smallest position size most brokers offer already risks more than that on any reasonable stop. So the account forces you to over-risk. The honest answer: enough that 1% of it is a tradeable position size, and money whose loss changes nothing about your life.
Why the minimum deposit misleads
"Start trading with $50" is an customer-acquisition number. It answers "what is the least you can deposit?" — a question about the broker's funnel, not about whether you can trade.
The question that matters is: at this account size, can I take a normal trade while risking a small percentage? For very small accounts the answer is usually no, and everything that goes wrong afterwards follows from that.
The arithmetic that decides it
Sensible risk is a small percentage of the account per trade — commonly 1%, sometimes less. Work it through:
— $100 account, 1% risk = $1 per trade. With a 20-pip stop you would need a position where each pip is worth $0.05. Most brokers' smallest size — a micro lot — is around $0.10 per pip. Your minimum possible trade already risks about double your budget. You cannot comply with your own risk rule.
— $1,000 account, 1% = $10 per trade. A 20-pip stop needs $0.50 per pip — about five micro lots. Now the rule is workable.
— $5,000+. You gain flexibility on stop distance, pair choice and volatility without breaking sizing.
Notice what this is not: a claim about how much you will make. It is only about whether you can execute a risk rule at all. Below that threshold you are not trading a strategy — you are forced into oversized positions and one normal losing streak ends the account. That is risk of ruin, arithmetic, not bad luck.
So is $500 enough?
It is enough to learn on with strict discipline, if your broker offers micro lots and you accept tight constraints on stops and pairs. It is not enough to earn from, and treating it as an income source is what causes the over-leveraging that destroys it.
The uncomfortable maths: a $500 account returning a genuinely excellent 5% a month makes $25. Nobody replaces an income with that — but people try, by pushing size until the return looks meaningful. That is the exact mechanism behind why most traders lose. The account size does not cause the loss; the expectation attached to it does.
The test that matters more than the number
Whatever figure you land on, it must pass this: losing all of it should change nothing about your life. Not your rent, not your obligations, not your ability to sleep.
This is not a motivational line — it is a performance requirement. Money you cannot afford to lose makes you cut winners early and hold losers hoping they come back, because each position carries consequences beyond the trade. Under-capitalised and emotionally over-committed is the worst combination in trading, and it is the standard starting position for most retail accounts.
Never fund a trading account with borrowed money, and never with money earmarked for something else.
What to actually do
Start at zero. A demo account costs nothing and teaches mechanics — platform, order types, sizing — without funding anything.
Then fund an amount whose 1% is tradeable, and that you can lose entirely without consequence. For most people that is meaningfully more than the broker's minimum and meaningfully less than they first imagine putting in.
Then trade smaller than feels worthwhile. The first year's job is to survive and build a record, not to earn. If the returns feel too small to matter, that is a sign your expectations need adjusting — not your position size. This is education, not advice.
Frequently Asked Questions
How much money do I need to start trading forex?
Enough that 1% of it is a tradeable position size — for most brokers offering micro lots, that means roughly $1,000 or more to follow a 1% risk rule properly. Equally important: it must be money you can lose entirely without it affecting your life.
Can I trade forex with $100?
You can open an account, but you cannot size properly. At 1% risk that is $1 per trade, while the smallest position most brokers offer already risks around double that on a modest stop. The account forces you to break your own risk rule.
Is $500 enough to trade forex?
It is enough to learn on with micro lots and strict discipline. It is not enough to earn from — an excellent 5% month is $25 — and treating it as income is what drives the over-leveraging that destroys small accounts.
Should I use high leverage on a small account?
No. Leverage does not solve under-capitalisation, it accelerates it. A small account with high leverage reaches risk of ruin faster than the same account traded conservatively.
Should I borrow money to fund a trading account?
No. Never fund a trading account with borrowed money or with money earmarked for something else. Beyond the financial risk, it damages your decision-making — you cut winners early and hold losers because every position carries consequences beyond the trade.
