Cost an FSx file system from SSD capacity, throughput capacity, backups, Multi-AZ and deduplication savings.
FSx bills provisioned capacity and provisioned throughput as two independent dials, and throughput capacity also determines the file server's network and cache limits rather than only its bandwidth. Multi-AZ mirrors both dials into a second Availability Zone, so it roughly doubles the compute and storage line before backups are counted. Deduplication is what makes the real cost per logical GB far lower than the sticker rate on general-purpose file shares — and every rate here is a user-supplied list price to confirm on the AWS FSx pricing page for your region. Throughput capacity is usually the surprise on an FSx bill: at a couple of dollars per MBps-month it can outweigh the storage line entirely, and it is the one dial teams over-provision by habit.
FSx Storage
cost = (GB x storage rate + MBps x throughput rate) x Multi-AZ factor + backup GB x backup rate; logical capacity = GB ÷ (1 − dedup ratio).
cost = (GB x storage rate + MBps x throughput rate) x Multi-AZ factor + backup GB x backup rate; logical capacity = GB ÷ (1 − dedup ratio).

This calculator takes 8 inputs: Provisioned storage capacity, SSD storage price, Provisioned throughput capacity, Throughput capacity price, Backup data retained, Backup storage price, Deploy Multi-AZ, Data deduplication and compression savings. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
Yes. It sizes the file server's memory cache and network throughput too, so raising it can improve metadata-heavy workloads even when the raw bandwidth was never the bottleneck.
