Paid plans start at $7.25/mo. There's also a free plan.
Slack pricing runs from Free to Enterprise+. The pricing page lists Pro at $7.25 per user/month with annual billing, or $8.75 monthly. Business+ is $15 annually or $18 monthly, while Enterprise+ lists an annual rate of $45 per user/month and no monthly rate. Free includes 90-day message history and up to 10 apps. The main trade-off: advanced AI starts on Business+, and the Frontline teams add-on has no published price.

02What the plan grid doesn't tell you
Annual rates are equivalents
Pro and Business+ show annual prices as per-user monthly equivalents alongside monthly rates. Enterprise+ lists only an annual rate.
Free has usage caps
Free includes 90-day message history, up to 10 apps, 1:1 huddles and 1:1 external messages—not the unlimited history and integrations listed on paid plans.
Advanced AI costs more
Pro includes Basic AI; Advanced AI is listed on Business+. The pricing details do not state a separate AI add-on price.
Frontline price not published
Slack lists a Frontline teams add-on, but the price is not published on the vendor's site.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Teams testing basic chat | Free | It costs nothing, but caps history at 90 days and apps at 10, with 1:1 huddles and external messages. |
| Teams needing full history | Pro | It adds unlimited message history and app integrations, group meetings and Basic AI, from $7.25 per user/month annually. |
| Teams needing advanced AI | Business+ | It includes Advanced AI and 12 SSO options; the listed annual rate is $15 per user/month. |
04Is Slack worth the money?
Slack is worth the price when a team will use its channels, integrations, external messaging and built-in meeting tools in one workspace. Free is a useful entry point, but its history and app limits are real constraints. Pro removes those caps; Business+ costs more for Advanced AI and additional SSO options. We would compare those specific needs against other team communication products before choosing—these pricing details do not establish that Slack is better than competitors.
