Key Takeaways

  • The profit factor measures the ratio of total profit to total loss over a period of trading. A ratio above 1 indicates a profitable system.
  • A profit factor between 1.25-2 is considered “good”. Between 2-5 is “very good”. Above 5 is “excellent”. However, profit factor alone doesn’t show maximum drawdown.
  • To improve profit factor, increase average profit per trade, cut losses quicker, avoid overtrading, and use stop losses.
  • Look at profit factor along with other metrics like Sharpe ratio, Sortino ratio, risk-reward ratio, and expectancy to get a comprehensive view of performance.
  • No single metric provides a complete picture. Use a combination of profit factor and other key ratios for a balanced assessment of a trading strategy’s viability.

What is Profit Factor?

Profit factor measures the ratio of profit to loss over a designated trading period. It’s derived by dividing the total profit by the total loss. While it can be computed both before and after trading commissions, it’s more realistic to calculate it after factoring in these commissions. Essentially, the profit factor indicates the profit earned per unit of risk. A profit factor exceeding 1 suggests that the trading system is profitable.

To understand this better, let’s break it down further into the profit factors’ components:

Gross Profit vs Gross Loss: These are two significant components in computing the profit factor. Gross profit is the total gains from successful trades, and gross loss is the total from unsuccessful trades in a set period. By comparing these two figures, (or dividing them in the case of the profit factor), we can gauge whether more money was made or lost. And now you know why a profit factor exceeding 1 means a profitable system – the higher the better!

But now let’s run through a few examples to make this crystal clear, and check your math with the below profit factor calculator.

How to Calculate Profit Factor

Trader pondering with trading terminal in background

There are three simple steps to follow when calculating your profit factor. To illustrate this, let's consider a scenario where you've made ten trades over a month.

Step 1: Calculate Gross Profit

Let's say seven out of these ten trades were successful. If each successful trade earned $100, then your gross profit for the month would be 7 (successful trades) x $100 = $700.

Step 2: Calculate Gross Loss

Now consider the remaining three trades that weren't so successful. If each unsuccessful trade lost $50, then your gross loss for the month would be 3 (unsuccessful trades) x $50 = $150.

Step 3: Calculate Profit Factor

Finally, divide your gross profit by your gross loss to find out your profit factor.

So in our example here, it’s going to look something like this:
Profit factor = Gross Profit ÷ Gross Loss
=   $700 ÷ $150
=   ~4.67

This figure tells us that for every dollar risked over this trading period; we made approximately four dollars and sixty-seven cents – also known as the payoff ratio, which is when we convert the profit factor to units of dollars risked.

Remember, a high-profit factor seems great but doesn’t always predict future success in trading systems! Always combine different metrics and analysis methods when examining performance data; don’t rely solely on one number and make sure you have a large sample size!

Alternative Ways to Calculate Profit Factor

There are a few variants to the Profit Factor formula that we can use to compare various scenarios. One such is:

ProfitFactorAltenative = (WinRate * AverageWin) / (LossRate * AverageLoss)

  • Average win is calculated by taking all winning trades and dividing them by the number of winning trades. It is the expected value of an average winning trade.
  • Average loss: This is calculated by taking the sum of all losing trades and dividing it by the number of losing trades. It is the expected value of an average losing trade.

Let's understand this with an example with five entry signals in a week. There is 1 winner (5000) and 4 losers (1500+ $1000+500+200). Thus, the profit factor is:

$5000/ ($1500+$1000+$500+$200) = 1.56

The result shows that the system is profitable, but the metric fails to show a low win rate and a high drawdown rate. It's going to be challenging to sustain multiple losses in a row, and that one trade alone cannot vouch for the entire trading system to be profitable.

Speaking of good…

What is a Good Profit Factor?

A ratio over one means we earn more than we lose. So, technically:

  • A factor higher than 1 denotes a winning system.
  • A factor lower than 1 denotes a losing system.

Trading strategies with a profit factor just over 1 are not worth it.

This is because you would like to trade these trading strategies first since even a tiny change in the market can render the trading strategy fruitless.

As a trader, we would always want to select a strategy with a high margin of safety. Anything in the range of 1.25 and 1.75 indicates a minimal safety margin.

Also, you will need to bear particular out-of-pocket expenses like trading platform fees, broker commissions, bank commissions, market data expenses, taxes, etc. These expenses are an integral part of the trading business, which you need to pay from your trading profits.

I don't trade any system below a 2.00 profit factor unless it's a hedge.

As general guidelines:

  • A profit factor below 1.25 is poor.
  • A profit factor between 1.25 and 2.0 is considered 'good.' This means that for every dollar risked in the market, you're bringing back between $1.50 to $2 in returns.
  • A profit factor between 2 to 5 is deemed 'very good.'
  • An 'excellent' grade is awarded when the system has an extraordinary PF above five; meaning for each buck put into play there are at least five coming out.

The best profit factor target depends on your risk tolerance and strategy goals, despite general guidelines.

And in table form:

Profit Factor RangePerformance Rating
Below 1.25Poor
1.25 - 2.0Good
2 - 5Very Good
Above 5Excellent

However impressive these numbers may sound though; they should not be viewed in isolation. For instance, I always pair the profit factor with the maximum drawdown.

Why? Because of losses…

The profit factor doesn't show back-to-back losses or the biggest drop in value. So, it's important to look at the biggest drop (maximum drawdown) to see how much you might lose before things improve. By looking at the profit factor in conjunction with other metrics like maximum drawdown, you can get a better picture of your trading strategy helping you make smarter trading choices.

What are Profit Factor Drawbacks?

Trader looking up with concerned look on his face

Imagine your trading system has a Profit Factor of 2. This means that for every dollar lost, two dollars are gained. On the surface, this seems like an excellent performance. However, if we dig deeper, it's not as straightforward as it first appears.

For instance, let's say this profitable factor came from one super successful trade among several losing ones. Does that mean your system is reliable? Probably not because it relies heavily on one huge win while overlooking multiple losses.

Now consider another aspect – time. You held onto some stocks for six months before they turned profitable while others were short-term trades lasting only days or weeks but incurred losses. The profit factor doesn't take into account the time element which can significantly impact investment decisions.

Let's delve into yet another scenario where volatility comes into play: Your trading strategy involves high-risk investments in volatile markets that swing wildly between profits and losses. In this case, using just the profit factor to judge performance can be misleading since it concentrates more on gross profit/loss and ignores net profit after taking expenses into account.

In each of these instances - whether dealing with inconsistent wins or ignoring time factors or risky strategies - viewing only the Profit Factor without considering other vital ratios would give you an incomplete picture of your trading performance.

To get a comprehensive view:

  • Look at how many transactions had been made by the system.
  • Check if any significant drop (maximum drawdown) exceeds your risk tolerance.
  • Determine variability (dispersion) in outcomes produced by the system.
  • Calculate winning trade ratio.
  • Find out average earnings per transaction.
  • Examine the equity curve and analyze periods growth versus drawdown.

Together with Profit Factor, these metrics will provide you with a more accurate analysis of your trading system’s effectiveness rather than relying solely on one metric like Profit Factor alone. 

Improving Profit Factor

To boost your profit factor, one of the most straightforward methods is to increase your average profit per trade. This can be achieved by setting higher target prices for your trades or holding onto profitable positions a bit longer. However, this should always be done within reason and in line with market conditions.

For instance, if you typically aim for a $2 gain per share traded and raise that to $3 without adjusting other factors like stop loss levels or total risk exposure, you may end up losing more than gaining.

1. Cut Your Losing Trades Faster

In trading, the only thing you really can control is your losses. If a trade isn't going as expected, don’t let hope dictate your decisions; instead, cut your losses quickly. It's essential to have an exit strategy even before entering into any trade.

For example, if you buy shares at $50 each with an expectation they will rise to $55 but drop to $48 instead; rather than waiting and hoping they'll rebound, sell them off immediately to limit further loss.

2. Avoid Overtrading 

Overtrading occurs when traders execute too many trades based on insignificant market movements or out of sheer boredom when there are no suitable trading opportunities. This leads to reduced profitability due to taking poor setups. Instead, take this time to study the market. This will improve your trading and save your pocketbook.

3. Use Stop Losses

Stop losses are tools used by traders that automatically close positions once prices reach certain predefined levels showing unfavorable movement against the trader’s expectations thereby limiting their potential losses.

Let's say you purchased stock at $100 per share expecting it would go up but decided that if it fell down below $95 then you would want out - setting a stop loss at $95 would automatically sell your stock if the price dropped to that level, limiting the amount you could lose. 

You should set a stop loss on every trade unless you have data to back it up why you shouldn’t. (Mean reversion strategies often perform better without stop losses with position sizing standing at the forefront to manage risk)

Profit Factor vs. Other Performance Metrics

Let's look at profit factor and how it compares to other popular performance metrics:

  • Gain-to-Pain ratio
  • Sharpe ratio
  • Sortino ratio
  • Risk-reward ratio
  • Expectancy

Gain-to-Pain Ratio

The Gain-to-Pain ratio compares monthly profits to monthly losses, highlighting effective risk management with a higher ratio. On the other hand, the Profit Factor measures the absolute relationship between gross profit and gross loss. Utilizing both metrics allows traders to view both relative and absolute performance, enhancing their insight into the profitability and risk of their trading strategy. 

Gain-to-Pain Ratio Pros

  • Takes into consideration all trading periods, not just profitable ones
  • Useful measure for determining long-term sustainability

Gain-to-Pain Ratio Cons

  • May be skewed if there are large gains or losses

This combination helps to ensure neither consistent small gains nor occasional large losses are overlooked, providing a fuller picture of financial performance and strategy robustness.

Sharpe Ratio

The Sharpe Ratio helps traders understand how much additional return they earn for taking on extra risk, by comparing the investment's excess return to its volatility.

Sharpe Ratio Pros

  • Takes into account both potential rewards and risks
  • Widely recognized standard in the finance industry

Sharpe Ratio Cons

  • Assumes normal distribution of returns which may not always hold true.

Blending profit factor with the Sharpe ratio provides traders a deeper insight into the strategy's overall performance, blending the perspective on risk-adjusted returns with absolute profitability, and enhancing decision-making.

Sortino Ratio

The Sortino Ratio measures the return to "bad" volatility (downside risk), showing how much additional return an investment provides relative to its harmful fluctuations.

Sortino Ratio Pros

  • Makes a distinction between good (upside) and bad (downside) volatility
  • More accurate representation when there's an asymmetry in upward/downward price movements

Sortino Ratio Cons

  • More complex to calculate compared to others

When used alongside the profit factor, it enriches traders' perspective by jointly examining the strategy’s performance concerning both negative volatility and overall profitability, facilitating a more nuanced investment analysis and decision-making.

Risk-Reward Ratio

The Risk-Reward Ratio compares the potential loss (risk) to the potential profit (reward) of a trade, helping traders understand how much they stand to lose versus gain. 

Risk-Reward Ratio Pros

  • Helps decide whether a trade is worth entering based on potential gain/loss scenario

 Risk-Reward Ratio Cons

  • Does not take frequency or magnitude of wins/losses into consideration.

Coupling this with the profit, traders obtain a balanced view of individual trade risk alongside overarching strategy effectiveness. Together, these metrics provide a clearer strategy assessment, aiding sounder trading decisions.


Expectancy provides traders with an average value of each trade, indicating whether a strategy is generally profitable or loss-making over numerous trades.

Expectancy Pros

  • Comprehensive, as it considers both profitability and risk
  • Takes frequency of wins/losses into account

Expectancy Cons

  • Can be misleading if used in isolation without considering other metrics.

When combined with the profit factor, traders gain a rounded view: understanding not only generalized per-trade performance via expectancy but also assessing overall strategy viability with the profit factor.

As you can see, there’s no perfect metric. Each metric has its nuances, and it’s important to view your strategies through the lens of multiple metrics to gain a full understanding.

The Bottom Line

We've now covered the core concepts around profit factor - how to calculate it, interpret the ratios, and techniques to boost it. Profit factor alone doesn't tell the whole story, so be sure to use complementary metrics too for a balanced view.
