Profit Factor In Trading

Profit Factor In Trading: Definition, Calculator, Video and Formula

Profit Factor is a key performance metric used in trading to assess the profitability of a trading system or strategy. It’s calculated by dividing the total profit generated by winning trades by the total loss incurred from losing trades. Essentially, it tells you how much profit you’ve made for every unit of loss.

The Profit Factor represents the relationship between a trading system’s total gross profit and total gross loss within a specified timeframe.

Profit Factor is a financial metric used to evaluate a trading strategy’s or investment portfolio’s profitability. It is calculated by dividing the total profit the strategy or portfolio generates by the total losses incurred. A profit factor greater than 1 indicates that the strategy or portfolio is profitable, with higher values suggesting better performance. It is a popular measure because of its simplicity.

In this article, we explain the Profit Factor and show you what a good Profit Factor is in trading. We also show you how it’s calculated and how you can interpret it. Moreover, we establish what a good profit factor in trading is: a good profit factor in trading has a value of more than 1.75 but preferably not above 4.

How do you evaluate a trading strategy? In hindsight, it’s easy to judge a strategy by its result -the CAGR or the annual return. However, a good strategy can’t be judged solely on the return or the CAGR. The Profit Factor is a handy tool for quantifying the quality of the return and the CAGR.

In trading, you don’t want to become a victim of resulting, as Annie Duke explains in her brilliant book Thinking In Bets. A good decision can lead to a bad outcome, and a bad decision can lead to a good result. When looking at just one decision, the quality of the decision is, of course, not necessarily linked to the outcome. However, the correlation between these two is high in the long run.

What is Profit Factor?

Profit Factor is a metric used in trading to assess the profitability of a trading strategy or system. It is calculated by dividing the gross profits the strategy generates by the gross losses. The formula for Profit Factor is:

Profit Factor = Gross Profit / Gross Loss

Here, “Gross Profit” refers to the total profits generated by winning trades, and “Gross Loss” refers to the total losses incurred from losing trades.

A profit factor greater than 1 indicates that the strategy is profitable, as the gross profits exceed the gross losses. The higher the profit factor, the better the trading strategy is considered to be in terms of profitability.

However, it’s important to note that profit factor alone doesn’t provide a complete picture of a trading strategy’s performance. It doesn’t consider factors such as the number of trades, the size of gains and losses, the risk-adjusted returns, or the consistency of profits. Therefore, it is often used together with other performance metrics to evaluate the overall effectiveness of a trading strategy.

What is a good Profit Factor in trading?

A good Profit Factor in trading (as a rule of thumb), is higher than 1.75, but we are not necessarily happy to see values above 4, either.

We want higher values than 1.75 because a strategy often yields real-time results worse than the backtest. It’s rare for a strategy to perform better in real life than on your screen. There are many reasons for that (something we will not discuss further in this article), and you want to have a “margin of safety” by selecting strategies with a reasonably high Profit Factor.

If the profit ratio is 1.25, you have a minimal safety margin, which is not ideal. Even small negative changes might cause the strategy to lose money. We consider 1.75 a low threshold, but we prefer to trade strategies with a number above 2.

You might think a very high reading is good, but that’s frequently not true. How could that be?

First of all, it might be a sign you have curve-fitted the strategy. Too many variables, too few signals, and too short a backtest period might lead to exceptional results that are unlikely to work on future and unknown data.

In such cases, your real trading might disappoint you. Thus, any numbers above four should make you wary.

You have to find out what kind of thresholds you want to use.

How to Use the Profit Factor Calculator:

  1. Total Profit: Enter the total profit you’ve made from your trades. This includes all gains you’ve realized from winning trades.
  2. Total Loss: Enter the total loss you’ve incurred from your trades. This includes all losses you’ve experienced from losing trades.
  3. Click “Calculate Profit Factor”: Once you’ve entered your total profit and total loss, click the button to calculate your profit factor.

Interpreting the Result from the Profit Factor Calculator:

  • A profit factor greater than 1 indicates that your trading strategy is profitable. The higher the profit factor, the better.
  • A profit factor of 1 means that your trading strategy breaks even, generating as much profit as it does loss.
  • A profit factor less than 1 indicates that your trading strategy is unprofitable. The lower the profit factor, the worse.

Key Considerations:

  • Accuracy of Data: Ensure that you’re inputting accurate figures for total profit and total loss to get an accurate assessment of your profit factor.
  • Risk Management: While a high Profit Factor is desirable, it’s essential to consider risk management. A high Profit Factor doesn’t necessarily mean a low-risk strategy. Always prioritize risk management to protect your capital.

How to calculate the profit factor:

To calculate the profit factor:

The ratio between gross profits and gross losses is the profit factor. If a strategy has accumulated 500 in profits and 250 in losses, the profit factor is two.

In short, the profit factor is a ratio that calculates the risk reward ratio.

The total profits and losses during the backtest period are summarized. If a strategy has 156 trades with losses and 199 with profits, the 199 profits are summarized and divided by the sum of the 156 losses.

How to use Profit Factor with other metrics?

To use Profit Factor with other metrics such as risk-reward ratio, win rate, and average gain-to-average loss ratio, it provides a comprehensive evaluation of the strategy’s performance.

By analyzing Profit Factor alongside these metrics, traders can gain knowledge into their trading approach’s overall profitability, risk management, and consistency.

How to interpret Profit Factor?

Interpreting Profit Factor involves understanding how much profit is generated for every unit of loss incurred. It represents the ratio of gross profits to gross losses. The formula for calculating Profit Factor is:

Profit Factor=Total ProfitsTotal LossesProfit Factor=Total LossesTotal Profits​

Here’s how to interpret Profit Factor:

  1. Values Greater Than 1: A Profit Factor greater than 1 indicates that the trading strategy or system is profitable. This means that for every unit of loss incurred, more than one unit of profit is generated. The higher the Profit Factor, the better the trading strategy’s performance.
  2. Values Equal to 1: A Profit Factor equal to 1 means that the strategy generates equal amounts of profit and loss. While this indicates a break-even scenario, it may not necessarily be desirable since it doesn’t account for trading costs such as commissions and slippage.
  3. Values Less Than 1: A Profit Factor less than 1 signifies the unprofitable trading strategy. In this case, for every unit of profit generated, there are more than one units of loss incurred. This indicates a poor performing strategy.

How to improve Profit Factor?

To improve Profit Factor, focus on maximizing gains while minimizing losses. The better the strategy, the better the Profit Factor.

Which strategies have high Profit Factors?

Mean-reverting strategies tend to have higher profit factors than, for example, trend-following strategies. Likewise, we rarely find many high Profit Factor strategies in FOREX and commodities.

Is the Profit Factor all about risk?

Profit Factor Trading Performance

Yes, the profit factor is all about risk. It measures the ratio of profit generated to the maximum drawdown incurred, reflecting the relationship between profitability and risk in trading or investment activities.

Let’s show you an example of the tradeoff between the number of trades and risk:

Let’s assume you have a strategy with a profit factor of 3, which is pretty high. It has generated 300 trades over the last decade and involves only two variables.

Thus, the chances of curve fitting are reduced (because it’s only two variables) but not eliminated (they never will be). Then, you start fiddling with the two variables by changing their values. When you limit the threshold to generate more trades, you notice a decreased Profit Factor, and the max drawdown worsens.

However, the strategy makes more money overall because of the increased trades. This is always the trade-off between assumed risk and payoff. No pain, no gain.

This trade-off is something you’ll face daily. You want as much profit as possible, but you also want to get the profit with the least amount of stress and headache.

One solution is to embrace automatic and mechanical trading. This allows you to trade many strategies that can smooth your returns.

It would be best if you had a portfolio of quantified strategies. Combining many strategies with only a profit factor of 1.75 (and might not be so attractive) might not be attractive, but the sum of the strategies might give a higher profit factor because of its diversity. The Holy Grail of trading is to trade as many uncorrelated strategies as possible.

You need to trade different markets, different time frames, and different types of strategies. The only limit is your capacity and imagination. The software is unlikely to be the restraint.

How does the profit factor account for risk and volatility?

The Profit Factor accounts for risk and volatility by considering how well profits offset potential losses, providing a measure of a strategy’s robustness.

However, the Profit Factor can indirectly reflect aspects of risk and volatility. For instance, a higher Profit Factor usually indicates that the strategy generates more profits relative to losses, which could suggest that the system effectively manages risk. Similarly, a lower profit factor might imply the strategy is riskier or more volatile, as it may experience larger losses than gains.

To better understand risk and volatility, traders often combine the profit factor with other metrics, such as the Sharpe ratio, which considers the risk-adjusted return, or drawdown analysis, which evaluates the maximum decline in value of a trading account from its peak. By examining these additional measures alongside the Profit Factor, traders might better understand the overall risk and volatility profile of a trading strategy.

How can you measure the profitability of trading opportunities using Profit Factor?

To measure the profitability of trading opportunities using Profit Factor, you calculate the ratio of gross profit to gross loss, where a ratio greater than 1 indicates profitable trading.

Profit Factor is a metric used to measure the profitability of trading opportunities. It’s calculated by dividing the total profit generated from winning trades by the total loss incurred from losing trades. The formula is:

Profit Factor Formula

A Profit Factor greater than 1 indicates that the strategy or trading system is profitable, as the profits outweigh the losses. The higher the Profit Factor, the more profitable the trading opportunities are perceived to be.


The Profit Factor is a mathematical metric that divides gross profits by gross losses. A good profit factor in trading is above 1.75. We would be skeptical if the value is lower than 1.75, but we are also skeptical if it is above 4. A realistic profit factor is around 2.

A low number indicates a less robust strategy, while a high reading might be too good to be true in real life. We aim for the averages in between and reckon our diversity makes for a smooth total return.

Why is the Profit Factor important in evaluating a trading strategy?

The Profit Factor is important in evaluating a trading strategy because it provides a clear measure of its profitability relative to its risk, helping traders assess its effectiveness and potential for success. The Profit Factor measures risk-reward by assessing the relationship between profits and losses. It helps traders gauge the effectiveness and robustness of a trading strategy.

What is considered a good Profit Factor in trading?

A good Profit Factor in trading is typically above 1.75. Values below this threshold may indicate a less robust strategy, while values above 4 could suggest potential curve-fitting.

Why is a Profit Factor of 1.75 chosen as a threshold?

A Profit Factor of 1.75 is considered a reasonable threshold as it provides a margin of safety. Values below this might lead to strategies that are vulnerable to small changes, while values above 4 may indicate potential over-optimization.
