Usage and Costs

Track current-period usage before it becomes a finalized invoice.

Compute usage

Compute is billed from resource-hours across the billing window:

• CPU in core-hours
• memory in GiB-hours
• storage in GiB-hours

In practice, that means billing follows the resources your clusters are allocated over time. Unused plan headroom is not billed.

Compute formula

resource quantity x hours x hourly rate

Current compute rates:

Resource	Rate	Monthly equivalent
CPU	£0.030/vCPU/hour	£21.90/vCPU
Memory	£0.006/GiB/hour	£4.38/GiB
Storage	£0.000116/GiB/hour	£0.085/GiB

Example

If a cluster is allocated 4 vCPU, 16 GiB memory, and 100 GiB storage for a full hour:

(4 x 0.030) + (16 x 0.006) + (100 x 0.000116) = £0.2276/hour

Observability usage

Each plan includes an observability allowance. Kupe tracks two things for billing:

• metrics usage by active-series P95 over the billing period
• logs usage by total ingest volume over the billing period, measured as uncompressed bytes received

Usage within the included allowance is covered by the plan.

If overage remains enforced, the allowance acts as a hard limit and no overage charge is added.

If a tenant admin allows overage, usage above the included amount is billed at the flat overage rates.

Overage rates

Resource	Rate
Metrics active series	£0.003/series/month
Log ingest	£0.30/GB/month

Overage formula

max(0, actual usage - included allowance) x unit rate

High Availability

Clusters with High Availability enabled run a replicated control plane, billed per hour while HA is enabled:

Resource	Rate	Monthly equivalent
HA control plane	£0.0205/cluster/hour	≈ £15.00/cluster

HA hours are metered like compute: you pay only for the hours HA was actually enabled, and disabling HA or deleting the cluster stops the meter. Hours accrued before a mid-period deletion are still included on your next invoice.

What you see in the console

The console splits this across two views:

• Usage shows your current pool usage, included observability allowance, and whether overage is allowed
• Billing shows the current-period estimate, breakdown by cost category, and completed invoices

If your plan changes during the billing period, the current-period estimate reflects the prorated result across the affected plan windows.

What the current estimate includes

The current-period estimate can include:

• compute charges accrued so far
• metrics overage accrued so far
• logs overage accrued so far
• High Availability hours accrued so far
• estimated credits applied so far

It is an estimate until the billing period closes and the invoice is issued.
