Slack pricing: what each plan costs

How much does Slack cost?

Slack has four plans: Free, Pro, Business+ and Enterprise+. You pay per user, per month, and the rate is lower when you pay for a year up front. These are the prices on Slack's own pricing page, checked on 7 November 2026.

Plan	Paid annually	Paid monthly	Main thing it adds
Free	$0	$0	90 days of message history, up to 10 apps
Pro	$7.25 per user a month	$8.75 per user a month	Unlimited message history and apps, group huddles
Business+	$15 per user a month	$18 per user a month	Advanced AI, single sign-on
Enterprise+	Price on request	Price on request	Enterprise search, extra security controls

Slack bills for each person on the plan, so the total moves with your headcount.

What does Slack cost for a team of 5, 10 or 25?

Multiply the per-user rate by your headcount. A team of 5 on Pro pays $36.25 a month when paying annually, and a team of 10 pays $72.50.

Team size	Pro, paid annually	Pro, paid monthly	Business+, paid annually	Business+, paid monthly
5 people	$36.25	$43.75	$75	$90
10 people	$72.50	$87.50	$150	$180
25 people	$181.25	$218.75	$375	$450

Every figure is a monthly cost. The annual columns need a commitment for the year, and the monthly columns can change with your team from one month to the next.

What do you get on Slack's Free plan?

Enough to try Slack properly, with three limits that most growing teams hit.

• Message history stops at 90 days. Slack's Free plan card says to upgrade to see the previous 12 months.
• Up to 10 apps. A team that connects its calendar, files, help desk and a few alerts can reach that quickly.
• Huddles are one to one. Group audio and video calls need a paid plan. The same goes for messaging people outside your company: one person at a time on Free.

The Free plan also includes Slack's Basic AI: conversation summaries, Slackbot and AI workflow generation.

Is Slack Pro worth paying for?

For most small teams that rely on Slack, yes, and the reason is history. On Free, a decision made four months ago is out of reach. Pro makes every message searchable for good.

Pro also removes the 10-app limit, opens huddles to groups and lets you work with up to 250 outside organisations in shared channels. It keeps the same Basic AI as Free.

If you only chat now and then and never look back further than a few weeks, Free may be all you need.

When does a small team need Business+?

When it wants Slack's fuller AI or company-wide sign-in. Business+ costs about twice as much as Pro and adds two things a small team might care about:

1. Advanced AI. Slack's plan card lists summaries, Slackbot, workflow generation, AI search, daily recaps and file summaries.
2. Single sign-on. People sign in to Slack through your company's identity provider, such as Okta or Google.

A team of 5 pays $75 a month for Business+ on annual billing, against $36.25 for Pro. If neither item matters to you yet, Pro does the job.

How can you pay less for Slack?

Three ways, all from Slack's own pricing page.

• Pay annually. Pro drops from $8.75 to $7.25 per user a month, and Business+ from $18 to $15.
• Use the introductory offer. Slack lists 50% off for 3 months on Pro and Business+ when you buy online within 7 days of creating a team, on monthly plans only.
• Stay on Free until history hurts. The 90-day limit is the usual reason to upgrade. Until you miss an old message, you aren't losing much.

What does Slack's price leave out?

Everything that isn't chat. Slack is the place a team talks, so most teams pay separately for email, a calendar, a task manager, a CRM and a help desk, then connect them to Slack with apps. The Slack bill is one line in a longer list, which a worked software budget for five people adds up.

If chat is all you want, Slack Pro is hard to beat on price, and its marketplace lists over 2,600 apps, far more than a small suite connects.

How does Mojobase compare on price?

Mojobase costs more than Slack alone and less than Slack plus the tools around it. It's $50 a month for the first person and $25 for each person after, so $150 a month for 5 people. That covers Email, Team chat, Calendar, Tasks, Files, Handbook, Customers and Numbers, with AI included.

Pick Slack if you're happy with your other tools and only need a place to talk. Look at Mojobase's Team chat if you'd rather have chat, email and customers in one place, where the AI can read all of it. The two are set out fact by fact in Mojobase vs Slack, and other options are in Slack alternatives.
