Minimum Initial Deposit
The minimum initial deposit for online stock brokers ranges from as little as $500 to over $10,000. For those with less initial trading capital, lower minimum deposits are usually the deciding factor.
If your account balance falls below this minimum, your broker may charge you a fee every month or every quarter. These fees often range between $10 to $20 per month or per quarter, but can be higher. Read the fine print if you plan on depositing the absolute minimum capital in to your account. Chances are you will fall below that minimum when you initially begin to trade.
