Website Bandwidth Calculator

This calculator helps you cut through the confusion. By entering your site's average monthly traffic, page size, and a safety buffer, you can get a clear, data-driven estimate of your needs. Use this number to confidently select a hosting plan that's both cost-effective and powerful enough to handle your visitors.

This section should appear after the calculator widget to explain the inputs to users who need more detail.

To get the most accurate estimate, follow these simple steps:

1. Monthly Page Views - This is the total number of times pages on your site are viewed each month. You can find this in your website analytics platform (like Google Analytics, Matomo, or Plausible) or your current hosting provider's dashboard.
2. Average Page Size (KB) - This is the average size of a single page on your site, including all images, scripts, and stylesheets. If you don't know this, 500 KB is a very conservative guess for a simple blog, while 2,000-3,000 KB (2-3 MB) is more common for modern sites with high-quality images.
   
   
   Pro Tip: For the best results, use a tool like GTmetrix or Google PageSpeed Insights to test several of your most popular pages. Note the "Total Page Size" for each and find the average.
   
   
3. Redundancy Factor - This is your crucial safety buffer. Website traffic is never stable; you'll have unexpected spikes from social media, email campaigns, or search engine crawlers.

• 1: No buffer. This is risky and leaves no room for growth or traffic spikes.
• 2 (Recommended): A healthy buffer that plans for double your average traffic. This is ideal for most businesses.
• 3+: Use this if you expect rapid growth or run mission-critical sites where downtime is not an option.

This section should follow the "How to Use" section, explaining what to do with the calculated numbers.
The calculator provides three key estimates. Here's how to interpret them:

Monthly Bandwidth (GB)

This is the most important number for choosing a hosting plan. When you compare plans, they will list a "Data Transfer" or "Bandwidth" limit (e.g., "100 GB/month" or "Unmetered"). Your calculated Monthly Bandwidth should be comfortably below this limit. This is the total amount of data your site will serve to all visitors in a month.

Yearly Bandwidth (GB)

This figure simply shows your monthly data transfer over a full year. It's useful for high-level budgeting or comparing hosting plans that are billed annually.

Required Speed (Mbps)

This is not the same as your total data transfer. This number estimates the connection speed (megabits per second) your server needs to handle your average traffic load without slowing down. Most modern hosting plans (even shared hosting) provide a connection speed (e.g., 100 Mbps or 1 Gbps) far higher than this, so it's rarely a bottleneck. The Monthly Bandwidth (GB) is the limit you are much more likely to hit.
