## Indicative from-price range

Indicative from-price range for self-hosting HashiCorp Vault Cluster on 3 servers: about $72 to $337 per month (USD), as of 2026-10-19, for the reference workload (Peak secret requests per second: 500; Total secrets/keys stored: 10000; PKI certificates managed: 0). From-price by provider, each the cheapest server in that provider's own shortlist: $72 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $147 on Google Cloud (e2-standard-2, 2 vCPU, 8 GB RAM, us-central1); $190 on Amazon Web Services (c9g.large, 2 vCPU, 4 GB RAM, us-east-1); $192 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $199 on Microsoft Azure (D2as_v7, 2 vCPU, 8 GB RAM, eastus); $199 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $787 on Servers.com (dl-01, 8 vCPU, 64 GB RAM, eu-west).

Reference workload:
- Peak secret requests per second: 500
- Total secrets/keys stored: 10000
- PKI certificates managed: 0

Price snapshot: 2026-10-19. Currency: USD. FX snapshot: 2026-10-19.

Configuration: Low end: 3 x basic-2vcpu-4gb (DigitalOcean, 2 vCPU, 4 GB RAM, about $24 per server per month). High end: 3 x rise-m (OVHcloud, 12 vCPU, 64 GB RAM, about $112 per server per month).

Methodology: This range is generated automatically from public provider price lists. It has not been reviewed by a person, it is not a quote, and it may differ from the total the calculator chooses for your own workload with its AI step. Method: the calculator's offer shortlist for the reference workload (the same ranking it builds before the AI step, up to 12 offers across providers; 12 here) is priced at its monthly list price in USD. The low end is the cheapest of the per-provider from-prices below and the high end is the median server of the combined shortlist, each multiplied by 3, the smallest baseline topology (three-node-raft). The from-price for each provider applies the same method to that provider's own shortlist (the calculator's ranking restricted to that provider), so it is the cheapest server that ranking offers there, not a recommendation. Prices are taken from the price snapshot dated 2026-10-19; prices quoted in EUR are converted with the ECB reference rate dated 2026-10-19. Servers with fewer than 2 vCPU or less than 4 GB RAM are not priced. Only server rental list prices for the product's own servers are counted: dependencies, licences, support, traffic charges, taxes and setup fees are not included.

HashiCorp Vault is a secrets-management system that centralizes storage, dynamic generation, and access control for credentials, encryption keys, and certificates. It brokers short-lived secrets to applications and infrastructure through policy-based authentication instead of long-lived static credentials scattered across config files.

## Baseline topologies

- three-node-raft: 3 nodes minimum; roles: vault-server
- five-node-raft: 5 nodes minimum; roles: vault-server

## What drives the cost

- Peak secret requests per second: Peak rate of secret read/write operations. Drives active node CPU and memory requirements.
- Total secrets/keys stored: Total number of secrets, keys, and configuration entries. Drives integrated storage size.
