What is the Website Bandwidth Calculator?
Estimate hosting or CDN transfer for a typical month using traffic and page-weight assumptions.
The estimate applies the entered cache reduction before adding the overhead allowance.
Formula and calculation method
transfer = page size × visits × pages per visit × (1 − cache savings) × (1 + overhead).
The calculation runs locally in your browser and uses only the values entered on this page.
Important limitations
Technology estimates simplify real systems. Hardware, software, network conditions, measurement conventions and manufacturer behavior can change actual results.
Planning scope: Use the result as an estimate and confirm critical sizing or configuration with current product documentation.
