Do I need a minimum amount of money to start investing?

No — the major brokers have eliminated account minimums, so you can open an account and start with as little as $1 thanks to fractional shares. The old barriers, like $3,000 minimums on certain index funds, are largely gone or can be sidestepped by buying the ETF version of the same fund for the price of one share or less. What matters far more than your starting amount is consistency: $200 a month invested steadily for 30 years compounds dramatically, while waiting until you have a "big enough" lump sum just costs you time in the market. Start with whatever you can spare into a broad index fund, then automate regular contributions. The habit beats the headline number.
