What does it cost?

Confluence price: $7.15 per user per month (Standard plan, monthly billing). Standard $7.15/user/mo, monthly billing, 1-100 users (after the 2026-10-13 price rise; was $6.70); Premium $14.10. Corroborated; the vendor page timed out on our fetch. Source: vendor pricing page, checked 2026-11-10. Vendor site: Confluence site. Put your plan's price into the estimator below if it differs.

Example values: replace every number with your own. SaaS price prefilled from Confluence pricing, checked 2026-11-10; the other numbers are examples.

Self-hosting saves about $96 a year for 20 seats: SaaS $1,716 vs self-host $1,620 (server $144, backups $36, admin time $1,440). Break-even at about 19 seats at these numbers.

Functions differ: an open-source tool rarely matches every Confluence feature. Self-hosting means you handle updates, backups and security. Sponsored plate: none yet. Advertise.
