How to Build a Social Media Cost Calculator with HTML, CSS, and JavaScript

If you're managing social media campaigns, you know how important it is to estimate costs effectively. Today, we'll create a simple Social Media Cost Calculator using HTML, CSS, and JavaScript. This tool will help you or your clients calculate ad spend, content creation costs, and management fees—all in real-time!

Why Build a Social Media Cost Calculator?

Whether you're a digital marketer or a business owner, a cost calculator:

• Saves time in budgeting.
• Provides clear insights into campaign expenses.
• Simplifies communication with clients or stakeholders.

Features of the Calculator

• Ad Spend Input: Budget allocated for ads on platforms like Facebook or Instagram.
• Content Creation Input: Cost for creating graphics, videos, or blog posts.
• Management Fees Input: Payment for social media account management.
• Real-Time Cost Calculation: Instantly calculates the total.

Step 1: HTML Structure

The HTML defines the layout of our calculator. Here's the code:

  
  
  


  

    
Social Media Cost Calculator
    

      

        Ad Spend (₹):
        
      
      

        Content Creation (₹):
        
      
      

        Management Fees (₹):
        
      
      
    
    
Total Cost: ₹0
  

Step 2: Styling with CSS

Add a clean, responsive design using CSS:

body {
  font-family: Arial, sans-serif;
  background-color: #f4f4f9;
  margin: 0;
  padding: 20px;
}

.calculator {
  max-width: 400px;
  margin: auto;
  background: #ffffff;
  padding: 20px;
  border-radius: 10px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}

h1 {
  text-align: center;
  font-size: 24px;
  color: #333;
}

.form-group {
  margin-bottom: 15px;
}

label {
  display: block;
  font-size: 16px;
  color: #555;
  margin-bottom: 5px;
}

input {
  width: 100%;
  padding: 10px;
  border: 1px solid #ddd;
  border-radius: 5px;
  font-size: 14px;
}

button {
  width: 100%;
  padding: 10px;
  background-color: #007bff;
  border: none;
  color: white;
  font-size: 16px;
  border-radius: 5px;
  cursor: pointer;
}

button:hover {
  background-color: #0056b3;
}

.result {
  margin-top: 20px;
  font-size: 18px;
  color: #333;
  text-align: center;
}

Step 3: Adding JavaScript

Implement logic to calculate the total cost dynamically:

document.getElementById("calculateBtn").addEventListener("click", function () {
  const adSpend = parseFloat(document.getElementById("adSpend").value) || 0;
  const contentCreation = parseFloat(document.getElementById("contentCreation").value) || 0;
  const managementFees = parseFloat(document.getElementById("managementFees").value) || 0;

  const totalCost = adSpend + contentCreation + managementFees;

  document.getElementById("totalCost").textContent = `Total Cost: ₹${totalCost.toFixed(2)}`;
});

Testing the Calculator

1. Copy and paste the code into three files: index.html, styles.css, and script.js.
2. Open index.html in your browser.
3. Enter different values to see the total cost update instantly.
