What does it cost?

Notion price: $10 per user per month (Plus plan, billed annually). Plus $10/user/mo billed annually ($12 monthly); Business $20/user/mo billed annually ($24 monthly). Corroborated from third-party reads of the vendor page; the vendor page did not render prices as text. Source: vendor pricing page, checked 2026-11-10. Vendor site: Notion 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 Notion pricing, checked 2026-11-10; the other numbers are examples.

Self-hosting saves about $780 a year for 20 seats: SaaS $2,400 vs self-host $1,620 (server $144, backups $36, admin time $1,440). Break-even at about 14 seats at these numbers.

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