Capacity planning

How database growth is estimated

01

Calculate daily ingestion

New records per day are multiplied by the average stored record size.

02

Project the selected period

Daily ingestion is converted to monthly growth and multiplied by the number of months.

03

Account for backups

The backup multiplier is applied to new growth, then added to the current database size.

Storage context

What else consumes database storage

✓

Indexes and overhead

Indexes, page fill, metadata, and storage-engine structures can add significant overhead.

✓

Logs and replicas

Transaction logs, read replicas, snapshots, and point-in-time recovery need separate capacity.

✓

Retention and headroom

Keep operational headroom for bursts, migrations, maintenance, and longer retention windows.

Common questions

Database storage growth FAQ

All calculators →
How is daily database growth calculated?

Multiply new records per day by the average record size, then convert the result into MB or GB.

Does the backup multiplier include the current database?

In this calculator it applies to projected new growth, while the current database is added once. This matches the displayed example.

Should I add storage headroom?

Yes. Production databases commonly need extra room for indexes, logs, replicas, maintenance, and unexpected growth.
