A clearer budget for your next container.

Enter your measured memory needs, keep a reserve, and see what remains. No sign-in, upload or server connection.

Example inputs are prefilled. Replace them with measurements for your host and workload. MiB and decimal MB are different units; use MiB consistently here.

Calculating

New service budgets—

Existing workloads + headroom—

Share allocated—

This is subtraction, not an automatic capacity assessment. CPU, storage, traffic spikes, container limits and recovery behavior need separate checks. Your inputs stay in this page.

How to choose the inputs

Measure existing workloads while they do their ordinary work. Give each new service an allowance based on a typical task and a larger task. Leave a reserve for overlap and the operating system. The default numbers are examples, not recommended allocations for named software.

Formula: remaining = total − existing workloads − headroom − new services. Negative means your chosen allowances exceed the total. A positive result does not prove your workload is safe under load.
