5 calculators available
IP Subnet Calculator
Calculate subnet mask, network address, broadcast address, first/last usable host IP, and total usable hosts from CIDR notation (e.g., 192.168.1.0/24) for IPv4 network planning and subnetting.
Use CalculatorData Transfer Speed Calculator
Calculate file transfer time based on file size and connection speed with automatic unit conversion (KB/MB/GB/TB and Mbps/Gbps). Includes overhead adjustment and 2026 typical connection speeds.
Use CalculatorServer Cost of Ownership Calculator
Compare on-premises server total cost of ownership (hardware, colocation, power, cooling, maintenance) vs. cloud IaaS over 3 to 5 years with 2026 AWS/Azure/GCP pricing benchmarks.
Use CalculatorIT Ticketing Backlog Burn-Down Calculator
Calculate days to clear IT support ticket backlog based on current queue size, daily ticket arrival rate, team resolution capacity, and target resolution SLA for help desk planning.
Use CalculatorCloud Infrastructure Cost Estimator
Compare AWS, Azure, and Google Cloud compute instance costs by region, instance type, and workload characteristics with 2026 on-demand and reserved pricing for multi-cloud cost optimization.
Use CalculatorIT professionals, system administrators, and network engineers manage infrastructure where IP addressing, data transfer, and server costs require precise calculations. From calculating subnet ranges and data transfer times to estimating server TCO and cloud costs, technical math underlies infrastructure decisions. Our tech and IT calculators help professionals plan networks, size systems, and optimize IT spending.
Why Use Our Tech & IT Calculators
IT infrastructure calculations require understanding binary math, network protocols, and capacity planning. IP subnetting uses CIDR notation and binary AND operations. Data transfer times depend on bandwidth and file sizes. Server TCO includes hardware, software, power, cooling, and admin costs over 3-5 years. Cloud costs vary by instance type, storage, and data transfer. Our calculators apply networking and IT standards.
Who Are These Calculators For?

How to Choose the Right Calculator
For network design, use the IP Subnet Calculator to plan CIDR ranges and calculate subnet masks. The Data Transfer Calculator estimates upload/download times for migration planning. System administrators need the Server TCO Calculator for hardware refresh cycles. For cloud decisions, the Cloud Cost Calculator compares providers and instance types.
Frequently Asked Questions
How do you calculate IP subnets?
CIDR notation (e.g., /24) determines host bits. /24 = 256 addresses (254 usable). /16 = 65,536 addresses. Formula: 2^(32-CIDR) = total addresses. Subtract 2 for network/broadcast (IPv4). Our calculator shows subnet ranges, broadcast addresses, and available hosts.
How do you calculate data transfer time?
Time = File size / Bandwidth. Account for overhead: TCP/IP adds ~10%, real-world throughput is 70-90% of line rate. Example: 1 TB over 1 Gbps = ~2.5 hours theoretical, ~3 hours real-world. Our calculator includes protocol overhead and efficiency factors.
Do you store network or infrastructure data?
No. All calculations run entirely in your browser. We do not collect, transmit, or store any IP addresses, network configurations, or infrastructure details. Your IT data remains private.
Disclaimer
Tech and IT calculators provide estimates based on networking standards and the inputs you provide. Actual network performance, transfer times, and costs vary by equipment, topology, provider, and conditions. IP addressing must comply with organizational and internet standards (RFC 1918 for private, registered for public). These tools are for planning and estimation purposes. Consult with network engineers, systems architects, and IT vendors for infrastructure design.
