Use our free Risk Of Ruin calculator to estimate trading risk. Check your ruin chance with win rate, pay-off ratio, capital, and trade risk.
The Risk Of Ruin calculator helps traders check their chance of losing their trading funds. It uses your win rate, pay-off ratio, and risk size. This can help you make a safer trading plan.
Think of your trading cash like a fuel tank. Each loss uses some fuel. Too many big losses can drain the tank. A good risk plan helps you stay in the game.
Our free tool makes this math quick and easy. You can use it to check your risk before you trade.
The main Risk Of Ruin formula used by this tool is:
Risk Of Ruin = ((1 - A) / (1 + A)) ^ U
Here:
A = (p × R) - q
p = Win rate as a decimal
q = Loss rate as a decimal
R = Pay-off ratio
U = Risk units
For a fixed risk plan:
U = Starting Capital / Risk Per Trade
For a fixed fraction plan:
U = ln(1 - D) / ln(1 - f)
Here:
D = Ruin drawdown level
f = Risk per trade as a decimal
The final result shows your estimated risk of ruin as a percent.
A low score means low risk. A high score means high risk.
You can use our Risk of ruin calculator free tool in a few steps.
The result can help you see how safe your current plan may be. You can then lower your trade risk if the score looks too high.
Let's say you have a $10,000 trading account. You win 55% of your trades. Your pay-off ratio is 1.5.
First, change the win rate to a decimal.
p = 55 / 100 = 0.55
Now find the loss rate.
q = 1 - 0.55 = 0.45
Next, find the edge.
A = (p × R) - q
A = (0.55 × 1.5) - 0.45
A = 0.375
Now, say you risk $100 per trade.
U = 10,000 / 100
U = 100
Now use the Risk Of Ruin formula.
Risk Of Ruin = ((1 - 0.375) / (1 + 0.375)) ^ 100
Risk Of Ruin = (0.625 / 1.375) ^ 100
The result is very close to zero.
This means the model shows an extremely low risk of ruin. Still, no tool can promise zero risk in real trading. Markets can change, and past results may not last.
Some users search for Risk Of Ruin calculator slots when they want a quick way to test risk values. The word "slots" may refer to input slots or tools that show risk data.
For trading, the key inputs are simple. You need your win rate, pay-off ratio, and risk size. For a fixed risk plan, you also need your starting funds. For a fixed fraction plan, you need your drawdown level and risk percent.
Use real trade data when you can. This gives you a better view of your risk.
Trading has risk. Even a good system can face a run of losses. Risk of ruin helps you see how much risk your plan may carry.
It can also help you:
Think of it as a seat belt. You hope you won't need it, but it's smart to have one.

Our Risk of ruin calculator free tool makes the math simple. You can test your plan in seconds.

Smart risk control is key. Protect your funds first. Then focus on growth.
A Risk Of Ruin calculator estimates the chance that a trading plan may lose its set amount of funds. It uses key data such as win rate and pay-off ratio.
The main formula is:
Risk Of Ruin = ((1 - A) / (1 + A)) ^ U
The value of A comes from the win rate, loss rate, and pay-off ratio.
Yes. A lower result means the model sees less risk of ruin. A high result means you may need to cut your trade risk.
The model may show a result that is very close to zero. But real trading always has some risk. No tool can promise zero loss.
You may need your win rate, pay-off ratio, starting capital, risk per trade, drawdown level, or risk percent. The exact inputs depend on the method you choose.
Yes. You can use our Risk of ruin calculator free tool to test your trading risk without doing the math by hand.
This term may refer to the input fields, or "slots," in a calculator. These fields let you enter key data for your risk test.
