Azure Monitor Cost Calculator

Price Log Analytics ingestion across pay-as-you-go and commitment tiers, with basic logs and extended retention.

About Azure Monitor Cost Calculator

A commitment tier is a daily minimum, not a cap: you pay for the full tier every day even if you ingest less, and anything above it bills at the same discounted rate. Routing verbose, rarely-queried tables to the basic logs plan cuts their ingestion price substantially, and retention beyond the included 31 days is charged per GB-month on everything you keep. Log Analytics ingestion is frequently the second- or third-largest Azure line item, and the two levers that actually work are table-level plan selection and a commitment tier sized just below your steady-state volume — verify the current per-GB prices and tier discounts in the Azure pricing calculator for your region.

Formula

Azure Monitor Cost

tier rate: Discounted per-GB price unlocked by the commitment level

Assumptions and limits

The result is derived only from the 8 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

How is Azure Monitor Cost calculated?

commitment tiers bill the whole tier every day at a discounted rate and charge overage at that same rate: cost = (tier GB × tier rate + overage GB × tier rate + basic GB × basic rate) × days + retention beyond 31 days. A commitment tier is a daily minimum, not a cap: you pay for the full tier every day even if you ingest less, and anything above it bills at the same discounted rate. Routing verbose, rarely-queried tables to the basic logs plan cuts their ingestion price substantially, and retention beyond the included 31 days is charged per GB-month on everything you keep.

Why does Azure Monitor Cost matter?

Log Analytics ingestion is frequently the second- or third-largest Azure line item, and the two levers that actually work are table-level plan selection and a commitment tier sized just below your steady-state volume — verify the current per-GB prices and tier discounts in the Azure pricing calculator for your region.
