What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A 1-OCPU, 6-GB Oracle Cloud Infrastructure (OCI) Ampere A1 VM running continuously for 30 days uses 720 OCPU-hours and 4,320 GB-hours. Both figures are below Oracle’s published monthly A1 allowances of 3,000 OCPU-hours and 18,000 GB-hours, respectively; a single stream at typical bitrates would also be well below the listed first 10 TB/month of outbound data transfer. That does not guarantee a zero bill: eligibility and other A1 usage affect allowance availability, and boot-volume or additional storage is billed separately. A precise paid total depends on region, configuration, storage, bitrate and account terms.
What the 30-day example costs in compute and traffic
The arithmetic gives a useful starting point, not a universal quote. Oracle’s public Cloud Price List, accessed October 3, 2026, lists monthly Ampere A1 allowances of 3,000 OCPU-hours and 18,000 GB-hours, plus a first 10 TB/month outbound-transfer tier at no charge in the listed regions. Whether an allowance applies to a particular tenancy depends on its account terms and other usage. Check Oracle’s Cloud Price List for current terms and regional rates.
| Resource or usage | 30-day example | Oracle-listed allowance |
|---|---|---|
| Compute: 1 OCPU × 24 hours × 30 days | 720 OCPU-hours | 3,000 OCPU-hours/month for Ampere A1 |
| Memory: 6 GB × 24 hours × 30 days | 4,320 GB-hours | 18,000 GB-hours/month for Ampere A1 |
| Outbound data at 1 Mbps continuously | About 0.324 TB, before protocol overhead | First 10 TB/month outbound tier listed as free |
| Outbound data at 3 Mbps continuously | About 0.972 TB, before protocol overhead | First 10 TB/month outbound tier listed as free |
| Boot volume and additional storage | Depends on volume configuration and use | Standard Block Volume pricing applies separately |
Traffic estimates use decimal terabytes and the calculation bitrate × seconds ÷ 8. A 30-day month has 2,592,000 seconds. Real transfer can differ because the stream’s bitrate varies and protocols add overhead. The 10-TB figure is Oracle’s listed first-tier allowance for outbound data transfer, not a promise that every account, region or related service is free.
Why there is no single monthly VM price
OCI Ampere A1 Flex is priced by selected OCPUs and memory as separate resources, and rates depend on region. For each resource, multiply the applicable regional hourly rate by its metered hours, account for any allowance that actually applies, and add storage and other paid services. Oracle bills flexible-shape use per second with a one-minute minimum. Use Oracle’s Cost Estimator or the regional price list with your actual configuration; a generic monthly dollar figure would hide important differences.

VM shape and region
A 1-OCPU, 6-GB VM is only an example. A1 lets you choose OCPUs and memory, and network bandwidth scales with OCPU count. Oracle notes that A1 capacity may be limited, so the shape may not be available in every region or at the moment you try to provision it. Consult Oracle’s compute shapes documentation for shape details and availability considerations.
Do not treat OCPU counts as interchangeable across architectures: A1 has one vCPU per OCPU, while OCI x86 shapes have two vCPUs per OCPU. Compare the selected resources and workload, not just the OCPU label.

Storage is a separate cost
A VM requires a boot volume, and boot volumes and additional block storage use standard Block Volume pricing in addition to compute. Choose the volume size and performance appropriate to the operating system, encoder and media files, then include them in the estimator. The A1 compute allowance does not eliminate this separate storage line item.
How to estimate your own nonstop stream
- Choose a region and VM shape. Select an available A1 Flex configuration or another shape that can run your chosen encoder and media. Do not assume a particular workload fits without testing it.
- Calculate monthly resource hours. For continuous operation over 30 days, multiply OCPUs by 720 to get OCPU-hours and GB of memory by 720 to get GB-hours. For example, 1 OCPU and 6 GB produce 720 OCPU-hours and 4,320 GB-hours.
- Check applicable allowances. Compare those totals with Oracle’s published monthly A1 allowances, but confirm eligibility and account-specific terms and account for other usage in the tenancy before assuming any resource is covered.
- Estimate outbound transfer. Multiply the actual sustained encoded bitrate in bits per second by the runtime in seconds, then divide by 8. Compare the result with Oracle’s applicable outbound-transfer tier. Bitrate, resolution and frame rate should suit the source video and YouTube’s current live encoder settings guidance.
- Add storage and other services. Include the boot volume, extra block volumes and any other OCI services required. Their costs are not included in the compute allowance calculation.
- Price the full configuration. Enter your region, resource amounts, runtime and storage in the estimator or use the regional rate card. Rates and public allowances can change, so check them when planning the deployment.
What can make the actual bill differ
- Other A1 use: The example’s resources fit within the published monthly allowances individually, but other A1 instances or usage in the same tenancy can consume those allowances.
- Account eligibility: Public price-list figures do not establish that every account receives the same allowance. Confirm the terms for your tenancy.
- Region and availability: Resource rates are regional, and A1 capacity may be constrained.
- Storage and related services: Boot volumes are required; storage and other services can add charges even when compute usage is within an allowance.
- Stream bitrate: Outbound traffic scales with the encoder’s sustained bitrate and runtime. Variable bitrate, protocol overhead and interruptions affect the actual total.
- Workload fit: The arithmetic does not prove the VM can encode a specific video reliably. Test the chosen configuration and monitor resource use before relying on it for a continuous broadcast.
Or let it run in the cloud
If your goal is a continuous prerecorded YouTube stream rather than managing a VM, StreamNeo runs the uploaded video or playlist from the cloud. Upload the recording or build a playlist, add your YouTube stream key, and go live. Nothing has to stay on at home; the video streams as uploaded, up to 4K 60fps, at one price per slot, and StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card, one free day per account. Monthly access is $9.99 per month. See StreamNeo, or start your free day.
