Money Management in Trading: How Much Capital Do You Really Need?
If you want long-term success in trading, understanding money management is essential. Many traders focus on finding the perfect strategy, but forget that how you manage your risk often has a much bigger impact on your results over time. Proper money management helps protect your account from large losses and gives your strategy the best chance to perform.
One powerful approach is to use a variable money management method, where you risk a set percentage of your account balance on each trade. This method means your trade size grows when your account grows, allowing your profits to compound over time. On the flip side, your risk decreases if your account goes through a losing streak, helping protect your capital during tougher periods.
The calculator below is designed to help you estimate exactly how much capital you need to trade an Expert Advisor (EA) or CFD strategy, based on your personal risk settings, broker requirements, and typical trade parameters. Just enter your settings, and you’ll see a step-by-step risk breakdown and a guide to account protection.

Money Management Explained: Key Concepts and Tips
What is Money Management in Trading?
Money management refers to the rules and techniques you use to control risk, set trade sizes, and protect your trading account from major losses. It is the foundation of sustainable trading, no matter your strategy or experience level.
Why Is Risk Per Trade Important?
The percentage of your account that you risk on each trade is a key decision. Most professional traders risk just 1-2 percent of their balance on any single position. This keeps losses small and prevents a few bad trades from wiping out your account. The calculator above lets you test different risk levels so you can see the real impact on your capital.
What Is Variable Money Management?
Variable money management (also called "fixed fractional" or "percent risk" money management) means that each trade is sized to risk the same percentage of your current balance. This approach helps you maximize growth during winning periods and minimize damage during losing streaks.
How Does Compounding Work?
When you use a percentage risk, your position size increases as your account grows. This is called compounding. Over time, compounding can make a huge difference in your total profits because your gains start working for you.
What is a Lot Size?
A lot is the standard unit size for trading instruments like forex, CFDs, metals, and more. For example, in forex, 1.00 lot usually means 100,000 units of the base currency. Your broker may allow smaller lot sizes like 0.10 or 0.01, making it possible to risk small amounts.
What Is a Pip and How Is Risk Calculated?
A pip is the smallest price movement in a trading instrument. Risk per trade is calculated by multiplying your stop loss (in pips), pip value, and lot size. The calculator handles these conversions for you, so you don’t need to do them manually.
Why Can’t I Use Less Than 0.01 Lots?
Most brokers set a minimum lot size of 0.01 for standard accounts. If your account is small, you may not be able to risk as little as you want per trade. The calculator above warns you if your desired risk per trade is lower than the minimum lot size allows.
What Is Drawdown?
Drawdown is a measure of how much your account drops from its peak value after a series of losses. Understanding and planning for drawdowns is essential, as all strategies have losing streaks. The calculator estimates drawdowns based on your risk and your EA’s worst losing streak from backtesting.
Reduce Risk by Trading a Portfolio of Strategies
Many professional algorithmic traders lower their risk and improve consistency by trading a portfolio of strategies, rather than relying on a single system. Diversifying across different EAs or approaches can help smooth your equity curve and protect your capital when one strategy hits a drawdown.
