Running an online store is a highly competitive business, especially in the ever-growing e-commerce industry. To stay ahead of your competitors and grow your business, you need to have a thorough understanding of your profits and expenses. This is where Return on Investment (ROI) comes in handy. In this article, we'll discuss everything you need to know to calculate ROI for your PrestaShop store.

Understanding Return on Investment (ROI)

ROI is a performance measurement that indicates the profitability of an investment and how much return you are receiving on the money invested. It helps online store owners to evaluate the performance of specific investments in the business. By calculating ROI correctly, you can determine which investments are generating a profit and which are not. This allows you to make informed decisions to maximize revenue and streamline your business operations.

Calculating ROI involves taking into account all the costs associated with the investment, including the initial investment, ongoing expenses, and any revenue generated. By subtracting the total expenses from the total revenue generated, you can determine the net profit or loss generated from the investment. This net profit or loss is then divided by the initial investment to calculate the ROI as a percentage.

What is ROI?

ROI is a financial ratio that expresses the net profit or loss generated from a particular investment. It is calculated as a percentage of the investment cost. A high ROI indicates the profitability of your investment, while a low ROI indicates a loss.

For example, if you invested $1,000 in a marketing campaign and generated $2,000 in revenue, your net profit would be $1,000. Dividing this by the initial investment of $1,000 would give you an ROI of 100%. This means that for every dollar invested, you generated an additional dollar in profit.

Why is ROI Important for Your PrestaShop Store?

If you manage an online store on PrestaShop, calculating your ROI provides crucial information to help you improve the profitability of your business. With this information, you can determine which parts of your online store are most beneficial and which parts generate the most revenue. Ultimately, ROI helps you understand your profitability and identify opportunities for growth.

For example, if you invest in a new product line and calculate the ROI, you can determine whether this investment was profitable or not. If the ROI is high, you may decide to expand the product line or invest more in marketing to increase sales. On the other hand, if the ROI is low, you may decide to discontinue the product line or adjust your marketing strategy to improve sales.

ROI can also help you make informed decisions about your business operations. For example, if you calculate the ROI for your shipping and fulfillment process, you may identify areas where you can reduce costs or streamline the process to improve efficiency and profitability.

In conclusion, understanding ROI is essential for any PrestaShop store owner who wants to maximize revenue and grow their business. By calculating ROI correctly and using this information to make informed decisions, you can identify opportunities for growth and improve the profitability of your online store.

Setting Up Your PrestaShop Store for ROI Calculation

Running a successful e-commerce business requires careful planning and analysis. One of the most important metrics that you need to track is your return on investment (ROI). ROI is a key performance indicator that measures the profitability of your business and helps you make informed decisions about your marketing and advertising campaigns.

Installing Necessary Modules

Before you start calculating ROI, you need to make sure you have necessary modules installed on your PrestaShop store. These modules will help you gather the data you need to calculate ROI accurately and efficiently.

One important module is the sales tracking module. This module will help you track your sales and revenue over time, and identify trends and patterns in your sales data. Another important module is the profitability monitoring module. This module will help you track your expenses and calculate your profit margins, so you can identify areas where you can cut costs and increase profitability.

You should also consider installing modules for advertising campaign analysis and marketing performance tracking. These modules will help you track the effectiveness of your marketing campaigns, and identify which campaigns are generating the most revenue and ROI.

Configuring Your Store's Settings

Once you have installed the necessary modules, you need to configure your store's settings to make sure they reflect the best practices of calculating ROI.

First, make sure you track all sales and expenses, including discounts, taxes, shipping fees, and other direct expenses. This will help you get a complete picture of your revenue and expenses, and calculate your net profit accurately.

You should also categorize each transaction accurately under different revenue streams. This will help you understand which revenue streams are performing well, and which ones need improvement.

Another important setting to configure is your store's shipping and handling fees. Make sure you charge a fair and reasonable shipping fee, and consider offering free shipping for orders over a certain amount. This can help increase your average order value and improve your ROI.

Finally, make sure you track your website traffic and user behavior. This will help you identify areas where your website can be improved, and optimize your website for better conversion rates and ROI.

By following these best practices and setting up your PrestaShop store for ROI calculation, you can make informed decisions about your business and improve your profitability over time.

Gathering Data for ROI Calculation

Identifying Key Metrics

The first step in calculating ROI is to identify the metrics that will be used to measure your profitability. These metrics typically include the cost of goods sold (COGS), your revenue streams, and your net profit. You need to track these metrics regularly to get the most accurate ROI calculations possible.

Tracking Sales and Revenue

The next step is to track your sales and revenue streams. This means tracking every sale you make, including the value of the sale and any related expenses. You should also keep track of revenue streams, such as advertising, affiliates, and other sources of income related to your online store. This data will provide a clear picture of how your store is performing overall.

Analyzing Marketing and Advertising Costs

Analyzing your marketing and advertising expenses is crucial to calculate ROI accurately. You need to track all the expenses related to promotions, such as advertising, email marketing, social media marketing, and other promotions to understand which ones are generating profits. This analysis should also help you identify underperforming promotions. By cutting down on low performing promotions, you can increase your ROI.

Calculating ROI for Your PrestaShop Store

The ROI Formula

The most common formula used to calculate ROI is to divide the net profit by the total investment cost. The formula is as follows:

ROI= (Gains from Investment - Cost of Investment) / Cost of Investment)* 100

Applying the Formula to Your Store's Data

Now that you have gathered all the necessary data, it's time to apply the ROI formula. Calculate the net income by subtracting all the expenses from the revenue. This should give you a clear understanding of the profits and losses from your store. Once you have these figures, you can easily calculate ROI using the formula.

Interpreting Your ROI Results

After calculating your ROI, it's essential to interpret the results correctly. A positive ROI means that you are earning a profit, while a negative ROI means you are making a loss. Keep in mind that ROI is always expressed in percentages. The higher the percentage, the more profitable your store is. You should always compare your ROI to previous periods to get a sense of your progress.

Strategies to Improve ROI in PrestaShop

Optimizing Your Store's Conversion Rate

One way to increase your ROI is to optimize your store's conversion rate. This involves optimizing the buying process, including providing an excellent user experience, promoting products more effectively, and reducing the number of abandoned carts.

Reducing Costs and Increasing Efficiency

Another strategy to improve ROI is to find ways to reduce costs and increase efficiency. Some ways to do this include reducing inventory costs, finding new suppliers, automating processes, and streamlining fulfillment.

Targeting High-ROI Marketing Channels

Last but not least, you should target high-ROI marketing channels to maximize your revenue. Identify the channels that are performing the best, such as social media or paid advertising, and allocate more resources to them to increase ROI.


Calculating ROI is vital to the success of any online store on PrestaShop. By understanding the formula and key metrics, evaluating your expenses, and implementing the strategies discussed in this article, you can make informed decisions to improve your store's profitability. With careful analysis and continuous optimization of your store's operations, you can increase ROI and stay ahead of the competition.
