The minimum investment in forex is flexible and depends on your broker, account type, and trading style. Many online brokers allow you to start with as little as $10 to $100 using micro or cent accounts. These accounts let beginners trade very small position sizes, which helps limit risk while learning.

That said, starting with the absolute minimum has drawbacks. Small balances can be wiped out quickly by normal market moves, especially if leverage is misused. A more practical starting range for beginners is often $300 to $1,000. This provides better room for risk management and reduces emotional pressure.

Ultimately, the right minimum investment is not about the lowest possible amount. It is about what you can afford to lose while still trading responsibly. Proper risk control, position sizing, and patience matter far more than starting capital.
