Welcome to Network Calculators — a collection of free, interactive tools designed for IT professionals, network engineers, and students. Our calculators are built to make complex networking and system administration tasks faster, easier, and more accurate.
From IP Subnet and VLSM planning to RAID capacity estimation and bandwidth simulation, our goal is to provide intuitive, visual calculators that turn technical concepts into simple, hands-on tools.
Every calculator is built using clean PHP, HTML, and JavaScript — with an emphasis on speed and accuracy. We continuously improve and add new utilities, so you can rely on this platform for all your network and infrastructure calculations.
