Position Size Calculator
Figure out exactly how much to invest in a trade based on your risk tolerance. Never risk more than you can afford to lose.
- Enter your account balance. This is the total amount in your trading account.
- Set your risk percentage. Most traders risk 1-2% per trade. If you have $5,000 and risk 2%, you're okay losing $100 on this trade.
- Add the entry and stop loss prices. Entry is where you buy, stop loss is where you sell if it goes wrong. The gap between them determines your position size.
- Optional: set a take profit. This shows your potential reward and whether the trade is worth the risk.
Calculator
Risk Amount is the maximum you'd lose if your stop loss gets hit. It's your account balance multiplied by your risk percentage.
Position Size is the total dollar amount you should put into the trade. This is calculated so that if the price drops to your stop loss, you only lose your risk amount.
Coins to Buy is your position size divided by the entry price. This is the exact number of coins to purchase.

Frequently asked questions
What is position sizing in crypto trading?
Position sizing is the process of determining how much of your capital to allocate to a single trade. It is based on your total account balance, the percentage you are willing to risk, and the distance between your entry price and stop loss. Proper position sizing helps you survive losing streaks and stay in the market long term.
How much should I risk per trade?
Most experienced traders risk between 1% and 3% of their account balance on any single trade. Beginners should start at 1% or lower. This means if you have a $10,000 account and risk 2%, the maximum you would lose on one trade is $200. This approach protects your capital even during a string of losses.
What is a good risk/reward ratio?
A risk/reward ratio of at least 1:2 is commonly recommended. This means for every $1 you risk, you aim to make at least $2. With a 1:2 ratio, you only need to win 34% of your trades to break even. Higher ratios like 1:3 give you an even bigger edge, but the trade-off is that your take profit target is farther away, so fewer trades will reach it.
