Slack Pricing in 2026: Every Plan, Real Cost Per User
Slack has four plans: a free tier, Pro at $7.25 per user per month (billed annually) or $8.75 billed monthly, Business+ at $15 per user per month annually or $18 monthly, and a custom-quoted Enterprise+ tier. Those advertised prices are the annual-billing rates — the numbers Slack puts in the largest font — so the monthly-billed price is always higher.
Prices change and Slack frequently runs introductory discounts (currently 50% off for three months on Pro and Business+), so confirm the current numbers on the official Slack pricing page before you commit. The rates below reflect Slack’s published pricing as of July 2026.
Slack plans at a glance
| Plan | Price (annual / monthly per user) | Best for |
|---|---|---|
| Free | $0 | Small teams testing Slack, short-lived projects |
| Pro | $7.25 / $8.75 | Growing teams that need full message history |
| Business+ | $15 / $18 | Companies needing SSO, compliance, advanced AI |
| Enterprise+ | Custom (contact sales) | Large orgs with multiple workspaces |
Enterprise+ is the tier Slack used to call Enterprise Grid; the “Grid” name is being phased out in favor of Enterprise+.
Free
The free plan costs nothing and never expires, but it exists to push you toward Pro. The hard limit is history: you only see the most recent 90 days of messages and files, huddles are 1:1 only, and you can connect up to 10 apps (Slack pricing). It’s genuinely fine for a small team or a short project, and it now includes a basic set of AI features like search and recaps. It stops working the moment your history matters or you want group huddles.
Pro
Pro is the real starting point for most teams: $7.25/user/month billed annually, $8.75 billed monthly. You get unlimited message history, unlimited apps, group huddles, and the ability to collaborate with outside organizations through Slack Connect. For a team that lives in Slack, this is the tier that removes the free plan’s friction.
Business+
Business+ runs $15/user/month annually or $18 monthly — roughly double Pro. You’re paying for the administrative and compliance layer: SAML-based SSO, SCIM provisioning, data-residency options, a 99.99% uptime guarantee, and more advanced Slack AI capabilities. If your IT or security team has requirements, this is usually where you land, not Pro.
Enterprise+
Enterprise+ has no published price — you talk to sales. It’s built for large organizations that need multiple connected workspaces, enterprise key management, DLP, HIPAA support, and 24/7 priority support. Verified purchase data from procurement platform Vendr puts real-world Enterprise deals at a median around $26 per user per month, so the “contact sales” tier lands well above the list-price plans.
The costs Slack doesn’t put in big type
The advertised price is the annual-billing rate. Every headline number on the pricing page assumes you pay for a full year up front. Choose month-to-month flexibility and you pay about 20% more per seat — $8.75 instead of $7.25 on Pro, $18 instead of $15 on Business+.
Slack AI is now bundled, not a $20 add-on. Slack used to sell Slack AI as a separate add-on at roughly $20 per user per month. That standalone add-on is no longer sold to new customers; AI features are now included in each tier and get more capable as you move up (Slack fair billing and AI). That’s good news if you wanted AI, but it also means the AI cost is baked into the per-seat price rather than optional.
You’re billed per active user, not per account — which cuts both ways. Under Slack’s Fair Billing Policy, you’re only charged for members who actually do something (send a message, react, open a file) within a rolling 28-day window, and inactive members generate a prorated credit on your next statement. It’s genuinely fairer than seat-based licensing, but it also means a burst of activity from dormant accounts can nudge your bill up without you adding anyone.
The 90-day history cap is an upgrade lever. The free plan’s biggest limitation isn’t a feature you’re missing — it’s that your own past conversations disappear from view after 90 days. Once your team has real history worth searching, the free plan effectively forces the move to Pro. We break down exactly what’s capped in Slack free plan limits.
Is Slack free?
Yes, permanently, but with real limits. The free plan gives you 90 days of message history, 1:1 huddles only, and a cap of 10 connected apps. There’s no time-limited trial that expires — the free tier just stays free with those constraints in place. For a small team or a short-lived workspace it works well; for anything where searchable history, group calls, or more than ten integrations matter, you’ll hit the ceiling fast. The full breakdown lives in Slack free plan limits.

When Slack isn’t worth it
Slack’s per-seat pricing scales with headcount, so a 50-person team on Business+ is looking at $9,000/year annually, or $10,800 month-to-month. If most of your team only reads occasional messages, or you mainly need one or two channels and a few integrations, you may be over-paying for a collaboration platform. Free alternatives and cheaper tools can cover lightweight use, and the trade-offs are worth weighing before you commit budget — see Slack alternatives, or compare Slack head-to-head in Slack vs Discord and Slack vs Microsoft Teams.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
