How to Build a Simple Crypto Risk Calculator in Google Sheets

Managing risk before entering a trade is easier when the numbers are visible.

In this project, I’ll show how to build a simple crypto risk calculator in Google Sheets. The calculator will use your account balance, risk percentage, entry price, stop-loss price, and target price to estimate how much capital should be allocated to a trade and what the potential risk/reward looks like.

This tool is not designed to predict the market or tell you when to trade. Its purpose is to make position sizing and trade risk easier to understand before an order is placed.

You only need a Google account and access to Google Sheets. No coding experience is required.

Open a new Google Sheet and create a simple input section for the values the calculator will need.

Add rows for Account Balance, Risk per Trade (%), Entry Price, Stop Price, and Target Price.

Keeping these values in one section makes it easier to change the trade assumptions later without editing the formulas.

For example, you could place the labels in column A and the values in column B.

A2: Account Balance

A3: Risk per Trade (%)

A4: Entry Price

A5: Stop Price

A6: Target Price

At this stage, do not worry about formulas yet. The goal is simply to create a clean input area.

The first calculation is the maximum amount of money you are willing to lose if the trade reaches the stop-loss level.

If your account balance is in cell B2 and your risk percentage is in B3, the formula can be based on:

Account Balance × Risk Percentage

For example, if the account balance is $5,000 and the risk per trade is 1%, the maximum dollar risk would be $50.

This value becomes the foundation for the position-size calculation.

Next, calculate the distance between the entry price and the stop price.

For a long position, this is the difference between the entry price and the stop price. You can also convert that difference into a percentage of the entry price.

For example, if the entry is $80,000 and the stop is $78,400, the stop distance is $1,600, or 2% of the entry price.

This tells the calculator how much the asset can move against the position before the planned loss is reached.

Once you know the maximum dollar risk and the stop distance, you can estimate the position size.

The basic idea is to divide the amount you are willing to lose by the percentage distance to the stop.

If your maximum risk is $50 and the stop is 2% away from the entry price, the estimated position value would be $2,500.

This keeps the monetary risk similar even when different trades use different stop distances.

A wider stop results in a smaller position, while a tighter stop allows a larger position for the same account risk.

Now add a simple calculation comparing the distance from Entry to Stop with the distance from Entry to Target.

For a long trade, the potential reward is the difference between the target price and the entry price. The risk is the difference between the entry price and the stop price.

If the potential gain is twice the planned loss, the trade has a 2:1 reward-to-risk ratio.

This does not tell you whether the trade is good, but it makes the relationship between potential loss and potential gain much easier to see.

Enter a few hypothetical trades and change one variable at a time.

Try making the stop wider and watch how the suggested position size becomes smaller. Then make the stop tighter and see how the position size increases.

You can also change the account balance or risk percentage to see how the calculator reacts.

The goal is to confirm that the spreadsheet responds logically before you use it as part of a real trading workflow.

The calculator becomes more useful when it is part of a consistent process rather than something used occasionally.

Before placing a trade, enter the planned entry, stop, target, account balance, and risk percentage. Review the resulting position size and risk-to-reward ratio before deciding whether the setup fits your plan.

This kind of workflow can be used alongside different trading platforms, including Binance, Bybit, OKX, and BYDFi. The spreadsheet handles the risk calculation, while the trading platform is used for market monitoring and execution.

This helps separate the trading idea from the position-sizing decision and makes risk easier to compare across different setups.
