Azure Log Analytics charges primarily by data ingested and data retained. The main cost drivers are daily data volume, query frequency, and the chosen retention period. This guide presents cost estimates, per-unit pricing, and practical budgeting tips.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Data Ingestion | $1.50/GB | $2.50/GB | $3.50/GB | Recorded daily ingestion depending on logs and telemetry |
| Data Retention Beyond 90 Days | $0.07/GB/mo | $0.10/GB/mo | $0.15/GB/mo | Retained data incurs ongoing storage fees |
| Data Export & Retention | $0.00/GB | $0.01/GB | $0.05/GB | Export or long-term archiving may add costs |
Overview Of Costs
Azure Log Analytics pricing focuses on data ingestion and retention. In the U.S., expect a per-GB ingestion charge and additional monthly retention fees for data kept beyond the default period. Assumptions: standard workspace, US region, no special commitments, and typical telemetry from servers and applications.
Cost Breakdown
Exact pricing varies by region and commitment level. The table below shows common cost components and typical ranges to help forecast monthly bills.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $0.00 | $0.00 | $0.00 | Logs themselves are priced by ingestion, not a materials fee |
| Labor | $0 | $0 | $0 | Administrative labor for monitoring only; not a direct Azure charge |
| Laboratory/Testing Time | $0 | $0 | $0 | Included in internal IT costs, not Azure |
| Permits | $0 | $0 | $0 | Not applicable for cloud logs |
| Delivery/Disposal | $0 | $0 | $0 | Data egress charges possible if exporting outside Azure |
| Taxes | $0 | $0 | $0 | Depends on state/local tax rules |
| Retention (per GB/mo after baseline) | $0.07 | $0.10 | $0.15 | Baseline retention included in some plans; extended retention costs apply |
Assumptions: region, data sources, retention needs, and possible data filters.
What Drives Price
Data volume and retention are the primary price levers. Larger log volumes from multi-server environments increase ingestion costs quickly, while longer retention periods add ongoing storage fees. Other drivers include data filtering rules, log source types, and whether samples are rolled up before ingestion.
Ways To Save
Apply data filtering and retention controls to lower costs. Techniques include sampling noncritical logs, setting shorter retention for nonessential data, and using price-aware data export strategies. Automating data roll-up and using summaries can reduce daily ingestion without losing critical insights.
Regional Price Differences
Prices vary by U.S. region due to data center costs. In major metros, ingestion may trend toward the higher end of the range, while rural regions can see slightly lower effective prices due to data locality. Typical delta ranges are +/-10% between urban, suburban, and rural deployments.
Real-World Pricing Examples
Three scenario cards illustrate common configurations and costs.
Basic Scenario
Specs: 50 GB/month ingestion, 90-day retention, minimal exports. Hours: 4-6 per month for maintenance.
Estimates: Ingestion $100-$175/mo; Retention $3.50-$7.50/mo; Total $103-$182/mo.
Assumptions: standard logs, no special data processing.
Mid-Range Scenario
Specs: 200 GB/month ingestion, 120-day retention, regular exports for analytics.
Estimates: Ingestion $400-$700/mo; Retention $20-$40/mo; Exports $0-$10/mo; Total $420-$750/mo.
Assumptions: mixed server and application logs; moderate export activity.
Premium Scenario
Specs: 600 GB/month ingestion, 365-day retention, scheduled long-term archives.
Estimates: Ingestion $900-$2,100/mo; Retention $60-$90/mo; Exports $20-$50/mo; Total $980-$2,240/mo.
Assumptions: broad telemetry, frequent data exports, archival needs.
Maintenance & Ownership Costs
Ownership costs include ongoing storage and potential export/archiving fees. Regular reviews of data sources, retention policies, and export requirements help keep total cost predictable. Budget for periodic policy updates as workloads change.
Pricing FAQ
Common price questions center on how to estimate monthly costs and what affects spikes. Use your current ingestion rate and retention plan to project costs, then adjust by applying filters, reducing sources, or shortening retention where feasible.
