Usage and Costs

Track current-period usage before it becomes a finalised 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

Billing follows what your clusters are actually 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. By default, the allowance is a hard limit: usage cannot exceed it, so no overage charge applies. If a tenant admin turns overage on, usage above the included amount is billed at the flat rates below instead of being capped.

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.
