Website Bandwidth Calculator

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

Follow these steps for the most accurate result:

1. Enter your Monthly Page Views

Use your website analytics (for example, Google Analytics, Matomo, or Plausible) or your hosting dashboard to find how many times pages on your site are viewed in a month.

2. Enter the Average Page Size (in KB)

This should include everything on a typical page: images, scripts, stylesheets, etc. If you don’t know the precise number:

• A simple blog might average around 500 KB.

• A modern website with high-quality images might average 2,000-3,000 KB (2-3 MB).

3. Select a Redundancy Factor

This gives you a buffer for growth and unexpected traffic:

• 1: No buffer - you are planning exactly for average traffic only (risky).

• 2 (recommended): Double your average traffic - a healthy buffer for most businesses.

• 3 or more: Use this if you expect rapid growth or operate mission-critical sites where downtime is not an option.

Once you’ve entered your values, the calculator will provide three key estimates. Here’s how to interpret them:

Monthly Bandwidth (GB)

This is the most important figure when choosing a hosting plan. Hosting plans often state a “Data Transfer” or “Bandwidth” limit (e.g., “100 GB/month” or “Unmetered”). Your calculated monthly bandwidth should sit well under that plan’s limit. This number represents the total amount of data your site will serve to all visitors in a month.

Yearly Bandwidth (GB)

This figure shows what your monthly data transfer would amount to over a full year. It’s useful for budgeting or comparing hosting plans that are billed annually.

Required Speed (Mbps)

This estimate tells you the connection speed your server requires to handle your averaged traffic load without slowing down. Note that most modern hosting plans (even shared hosting) provide far higher connection speeds (such as 100 Mbps or 1 Gbps), so this is rarely the bottleneck; the Monthly Bandwidth (GB) limit is far more likely to be the constraint.
