🖥️ Server Cost Calculator
Cloud hosting cost estimate for AWS instances
About this calculator
Cloud servers bill by the hour for compute, storage, and bandwidth, and this calculator totals it up. Enter instance size or vCPU/RAM, hours per month, storage size, and expected data transfer — it estimates the monthly bill and the effective hourly rate, with room to compare on-demand versus reserved pricing.
Monthly cost equals (hourly rate × hours) plus storage gigabytes × per-GB price plus transfer gigabytes × per-GB price. The trap is forgetting the extras — a cheap instance with heavy egress fees often costs more than a pricier all-included one.
Tip: If a server runs 24/7, reserved or committed-use pricing typically cuts 30 to 60 percent off on-demand rates — only pay on-demand for spiky or experimental workloads.
