Observability & SRE
Log Retention Sizing Calculator
Log volume compounds with three multipliers nobody wants to think about during an initial deployment: how many days of retention you keep, how many copies the backend stores, and how much indexed-search overhead rides on top of the raw bytes. The multipliers combine inside the calculator below into the storage number the observability backend has to be provisioned against before the first log ships.

About this tool
Log Retention Sizing Calculator
Size log retention storage from daily ingest rate, retention days, replication factor, and index overhead. Browser-only — no data sent.
• Estimate the storage a log backend needs for your retention window
• See how replication, index overhead and compression change the total
• Size storage before the first logs ship
FAQ
What does this tool tell you?
Size log retention storage from daily ingest rate, retention days, replication factor, and index overhead. Browser-only — no data sent.
What affects the result most?
Size log retention storage from daily ingest rate, retention days, replication factor, and index overhead. Browser-only — no data sent.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
