Online Marketing Conversion Calculator

This online marketing conversion calculator helps you calculate and measure the success of your internet marketing and sales, from ad impressions and views to actual sales and return on investment (ROI).

You can use this calculator to simulate your marketing funnel and decide whether the marketing campaigns and programs you are planning or just set up will be profitable.

Return on investment (ROI)

Is this campaign working and driving enough revenue to cover the marketing costs? The third section of the digital marketing conversion  & ROI calculator helps you understand that.  To get the answers, type in the revenue you made in total on your sales and you can then calculate all of the other metrics.
  • Revenue: Total (gross) amount of money from all sales driven by the campaign. 
  • ROI: Return on investment, a percentage value that tells you how profitable your business is. The higher the ROI, the better. If the ROI is a negative value, you are currently losing money. 
  • Revenue per click / per lead / per customer: these values are self-explanatory. They are a good measure of how profitable this business is compared to others.
You can open the advanced mode to forecast revenue using some assumptions or predictions.
  • Number of orders per customer: Total number of orders that one customer makes with your business during their lifetime
  • Customer LTV (Lifetime Value): Total amount of money that one customer spends with your business during their lifetime
  • Total revenue: Total money your business makes. (Note: This includes the assumption that each of your customers will make the specified number of orders per customer.)

Costs of internet marketing

Advertising online is an amazing way to grow your brand and business. In order to maximize the results of your digital advertising campaigns, you can use these calculators to determine what your costs are and how much you are paying at each stage of your marketing funnel, whether that be per click or per customer.


  • Cost: Total cost of your online marketing and advertising. You can use the website ad revenue calculator to help calculate this.
  • CPM: Cost Per Mile, or Cost Per Thousand Impressions. For more details on this statistic, take a look at the CPM calculator.
  • CPC: Cost Per Click, or Cost Per Site Visit.
  • CPA: Cost Per Action or Cost Per Acquistion. The total cost of advertising required to get a user to complete some action or behavior like a purchase, download, form completion.
  • CPL: Cost per lead. The total cost of advertising required to get one lead.
  • Cost per customer: Total cost of advetising required to get one customer.

Marketing funnel

Even with the best and most compelling advertisement ever, most customers will leave a website without completing an action or buying anything and never come back. 

Some will become potential customers that return because they are interested in your product but are not yet ready to complete a transaction or become a customer. 

This drop off through each stage of the customer journey is typical and when measured can be a valuable KPI (key performance indicator) along with the conversion rate in optimizing your digital advetising campaigns and landing pages.

This calculator helps you determine the amount of people at each stage of the marketing funnel based on some benchmarks or assumptions.

  • Impressions: Total number of views of your ad. Every time a website with your ad is loaded, you get one impression.
  • CTR (click-through-rate): Percentage of impressions that lead to a click. For example, if your CTR is 5%, then that means that 1 of every 20 people who see this ad clicks on it and visit your website.
  • Visits: Total number of visits to your website
  • Visits to Leads: Percentage of visits that result in leads. For example, a visits to leads ratio of 10% means that one in every ten website visitors is interested in your product.
  • Leads: Total number of leads.
  • Leads to Customers: Percentage of leads that result in someone purchasing your product or becoming a customer.
  • Customers: Total number of website visitors who purchase something or become a customer.
