Free Trading Calculators & Tools
Use free calculators for position sizing, stop loss planning, risk-reward, ATR-based sizing, partial exits, trading expectancy, drawdown recovery, and risk of ruin. Choose the decision you need to make first, open the matching tool, and move to the next calculator only when it adds something useful.

Start with the decision you are trying to make
Size the trade if you already know your entry and stop. Check risk-reward if you are deciding whether the setup is worth taking. Use the stop calculator when acceptable loss and position size are known but stop placement is not. Use ATR when you want volatility to influence sizing and stop distance.
Match the Calculator to the Decision
You do not need every calculator on every trade. Use this table to start with the tool that answers the question in front of you, then follow the linked next step only if you need it.
| Decision | Start with | What it helps you answer | Useful next tool |
|---|---|---|---|
| Position Sizing How large can this trade be without exceeding my risk limit? | Position Size Calculator | Turns account risk plus entry-to-stop distance into a position-size decision. | Risk Reward Calculator |
| Setup Quality Is the potential reward large enough relative to the planned downside? | Risk Reward Calculator | Compares downside, upside, percentage distances, and the reward-to-risk structure before entry. | Position Size Calculator |
| Stop Placement What stop price fits the loss I am willing to accept? | Stop Loss Calculator | Works backward from acceptable risk and position size to estimate a stop level. | ATR Position Size & Stop Loss |
| Volatility How can ATR influence stop distance and position size? | ATR Position Size & Stop Loss Calculator | Connects volatility, ATR multiple, stop distance, position size, and R-based targets. | Risk Reward Calculator |
| Partial Exits How does scaling out change the total reward captured? | Partial Take Profit Calculator | Models multiple exit targets, assigned percentages, blended reward, and remaining runner size. | Risk Reward Calculator |
| Strategy Edge What does my average win/loss profile imply over many trades? | Trading Expectancy Calculator | Combines win rate and average wins/losses into an expected outcome per trade. | Risk of Ruin Calculator |
| Drawdown How much return is required to recover from a loss? | Drawdown Recovery Calculator | Shows why percentage recovery requirements accelerate as a drawdown becomes deeper. | Risk of Ruin Calculator |
| Survival Risk How aggressive is my combination of edge and risk per trade? | Risk of Ruin Calculator | Estimates long-run account survival risk from the assumptions you provide. | Trading Expectancy Calculator |
Five Calculators for Planning a Trade Before Entry
These tools sit closest to the trade itself. Use them to translate a chart idea into size, risk, stop distance, target structure, volatility-adjusted planning, and partial exits before capital is committed.
Position Size Calculator
Enter account size, risk, entry, stop, optional target, fees, and leverage to estimate position size, actual risk, margin, and potential reward.
Risk Reward Calculator
Compare planned downside with potential upside and check the reward-to-risk structure before deciding whether the setup deserves capital.
Stop Loss Calculator
Work backward from acceptable loss and position size when you need to estimate a stop price instead of choosing one by guesswork.
ATR Position Size & Stop Loss Calculator
Use ATR and an ATR multiple to connect market volatility with stop distance, position size, actual risk, and R-based target levels.
Partial Take Profit Calculator
Model multiple targets, exit percentages, blended reward, weighted average exit, and any position size left open as a runner.
Not Sure Which Three to Use?
For a normal trade plan, start with position size, validate the reward-to-risk structure, then refine stop or exit logic only if the setup needs it.
Three Tools for Looking Beyond a Single Trade
A good-looking setup does not tell you whether the strategy has an edge or whether the account can survive a difficult run. Use these tools after you have enough assumptions or trade data to evaluate the bigger picture.
Trading Expectancy Calculator
Combine win rate, average win, and average loss to estimate what the strategy is expected to produce per trade under the assumptions you enter.
Drawdown Recovery Calculator
See the return required to recover from a drawdown and why avoiding deeper losses matters more than the raw drawdown percentage suggests.
Risk of Ruin Calculator
Pressure-test how edge and risk assumptions affect the estimated probability of severe account damage over a long sequence of trades.
Use the Tools in a Logical Order
A calculator is most useful when it answers the next decision in your process. These three paths cover common planning, volatility, and system-review workflows without forcing every tool into every trade.
Size → Validate → Refine
Size the trade first, check whether the upside justifies the downside, then refine stop placement if necessary.
ATR → Risk/Reward → Scale Out
Let volatility influence size and stop distance, check the trade structure, then model partial exits if your strategy uses them.
Expectancy → Drawdown → Ruin Risk
Estimate edge first, understand the recovery burden of losses, then pressure-test whether the risk assumptions are too aggressive.
When the Math Is Done, Move Back to the Trading Workflow
Calculators should answer a specific question, then get out of the way. Use these broader resources when the next problem is chart setup, discovery, alerts, backtesting, or turning the plan into a repeatable TradingView routine.
TradingView Workflow Tools
Move beyond calculations into chart setup, watchlists, pre-market preparation, alert planning, paper trading, trade plans, and backtest review.
TradingView Tutorials
Go back to the platform guides when the bottleneck is charts, alerts, screeners, Pine Script, Strategy Tester, or another TradingView feature rather than the calculation itself.
Test the Strategy Before Trusting the Numbers
Expectancy and ruin estimates are only as useful as the assumptions behind them. Use Strategy Tester and backtest-review tools when you need a stronger evidence base.
Find the Setup Before You Size It
Use the live dashboard or TradingView screener when you still need market context or candidates before moving into detailed trade planning.
One Decision, One Calculator, Then the Next Step
Start with the question that is unclear right now. If it is trade size, use Position Size Calculator. If it is setup quality, use Risk Reward Calculator. If the math is already clear, move into the TradingView workflow instead of adding another calculator for no reason.
