How to calculate Return on Investment (ROI)

  ROI is a standard metric used worldwide, with the following basic formula:

ROI (%) = ( Net Profit ÷ Investment Cost) × 100

example

• Advertising budget : 100,000 baht
• Generated sales of 350,000 baht.
• Cost of goods: 150,000 baht
• Net profit of 100,000 baht.

so

ROI = (100,000 ÷ 100,000) × 100

ROI = 100%

  1 baht invested can generate a profit of 1 baht. However, in real business operations, calculating ROI is often more complex than the basic formula because it must include costs from many different areas, such as:

• Advertising costs
• Employee wages
• Software costs
• Agency fee
• Design fee
• Website costs
• Hosting costs
• Data analysis tool costs
• Customer care expenses.

  For this reason, the use of... Expert Return on Investment (ROI) services help ensure accurate, comprehensive calculations that better reflect business results.

 

Key KPIs in ROI analysis.

  While ROI is the primary measure of return on investment, accurate analysis requires considering other KPIs to gain a comprehensive overview of business performance.

1. Conversion Rate

  The rate at which website visitors or interested parties are converted into customers. A high conversion rate indicates that the marketing strategy and website are effectively persuading customers to make a purchase or register.

2. Customer Acquisition Cost (CAC)

  The average cost of acquiring one new customer. If the Cost-Acceptance (CAC) is low but sales are high, it indicates that the business is acquiring customers efficiently, resulting in a better Return on Investment (ROI).

3. Customer Lifetime Value (CLV)

  The total value that a single customer creates for a business over the duration of their customer relationship. Businesses with a high CLV ( Clear Value ) tend to generate better returns on investment than businesses that focus on one-time sales.

4. Return on Ad Spend (ROAS)

  A specific indicator of return on advertising spending. Although ROAS is similar to ROI , ROAS focuses only on revenue generated from advertising, while ROI considers all costs of the business as well.

5. Revenue Growth

  Revenue growth over different periods. If revenue continues to increase after the marketing campaign is completed, it signals that the plan is effective and has a positive impact on ROI.
