CRO calculator for measuring business revenue potential

Is Conversion Rate Optimization (CRO) a strategic investment in your business growth, or just an additional expense? To help you answer this question, we’ve created a CRO calculator that allows business owners to quickly assess how they can boost their profits through UX/UI optimization.

Conversion rate optimization: key concepts and value for online business

Before considering the principles and benefits of the mentioned calculator, let's first look at what the acronym CRO stands for.

Conversion rate optimization (CRO) — a set of specific steps aimed at turning your website visitors into customers. The better customer experience you offer, the higher the chances that customers will perform the desired action, like buying your products or services.

For that reason, the main CRO goal is to identify and eliminate all obstacles that prevent website visitors from completing a purchase.

Due to severe competition in online business, CRO is a critical tool for brand growth and scaling. After all, even the most effective advertising won't reward you with great results if people get stuck when trying to buy from your website.

A well-thought-out CRO strategy allows you to make your website more client-oriented, intuitive, and engaging, leading to increased sales without extra investments in advertisement. 

Conversion calculator: instruction manual

For those who still doubt if investing in CRO is worth doing, Turum-burum offers to use a conversion rate optimization calculator as long as this tool will help you:

• Forecast how you can boost your profit via increased conversion;
• Determine whether investing in CRO is a worthwhile decision for your business.

The calculator has a clear, easy-to-use interface that takes less than two minutes to fill in. It consists of two colored blocks: a purple one for displaying information about the current website performance and a green one for assessing the business potential.

How to use a CRO calculator? 

1. Purple block

The work with the CRO calculator starts with the purple block. You need to fill in only the first three boxes and specify the website’s: current conversion rate, average number of sessions per month, and average check. The rest will be automatically calculated and filled in by the system.

In case you don't know your business conversion, we recommend focusing on the average market rates. For example, the average conversion of the websites in the fashion niche is currently 1.5%. For electronics stores, this figure is about 1.6% — that’s the percentage of users who complete a purchase on the site.

To find the average number of sessions per month open: Google Analytics → Audience → Overview. 

While determining the current average check, take into account the average figures within the last few months.

2. Green block  

Here we go to the next step — the green section of the CRO calculator — where you have to specify the desired conversion rate increase. Then the system will automatically calculate all related metrics, including the potential growth of your e-commerce revenue.

And since after Turum-burum redesign our clients usually get a conversion rate increase between 14-55% depending on the project, you can focus on these indicators.

CRO investments: what is the pay-off period? 

There are many companies today that help online business owners increase their profits by improving the user experience of their web products. 

Thus, Turum-burum provides an extensive list of services that allow you to boost your business revenue just in a few weeks or months:

• UX audit of the current website version — an expert usability assessment of the key website pages;
• Visual presentation of the most critical interface issues with detailed explanations;
• Development of design layouts in Figma and their testing;
• Preparation of pages’ design and their testing;
• Implementation of the developed design by our partners or your in-house team under our supervision;
• A detailed plan on how to boost your business income with expert recommendations and clear explanations, which the business owner can use at his/her discretion. 

P.S.: The list of services varies based on the customer's needs and business specifics to maximize the achievement of project goals.

Our professional team handles everything from website analysis to implementing UX/UI improvements, ensuring a smooth process and reduced risks for business owners.

But how long does it take to see the benefits of a CRO investment? To answer this, let’s look at a potential case example.

Imagine we assess the growth opportunities of an online women's clothing store. As we already know, the average conversion for the fashion niche is currently 1.5%, and the average check for a dress or trousers is around $50. 

As for the number of sessions per month, let's consider the case of a medium-sized business with approximately 30,000 users per month.

When it comes to the desired conversion rate increase, let’s consider a scenario where we achieved a 14% conversion rate increase — typically the minimum result for our studio's cases. 

What do we have?

As you see, with the given parameters and a 14% conversion rate increase, a business can generate an additional $3,150 in revenue the next month after implementing the CRO strategy.

A full conversion rate optimization package offered by the Turum-burum team costs $3,400, meaning a company will need just around 1 month to pay off its investments in CRO. Everything earned after that is the company's net profit.

But what if we increase conversion not by 14% but by 22%, as we did for the glo™ website?

In this case, we will generate an additional $4,950 for business and get a payoff period of less than 3 weeks.

But it is not the maximum you can get by investing in CRO. For example, for Intertop we increased conversion by 55%.

If we achieve similar results in this case, we’ll generate over $12,000 in additional revenue next month, recovering our investment within just one week.

Still doubt whether CRO is a smart investment for your business? Check it out with our conversion calculator!

Important: The price of a CRO should be calculated individually for each project, as it depends on many factors: project size, business niche, and the list of required services. Therefore, the payback period usually varies from several weeks to several months (averagely 2.5–3 months).

CRO strategy: investment or not?

In a highly competitive online business environment, smooth and client-oriented UX/UI is a key to retaining loyal customers and ensuring stable business profits. That’s why regular interface improvements are crucial for the success of any web product in 2025.

And as the conversion calculator and real data demonstrate, even a slight increase in conversion rates can significantly impact the brand's profits.

That's why CRO strategy shouldn’t be viewed as an expense but as a smart investment that can quickly pay off and ensure stable business growth in the future.
