Slack ($6.25–$12.50/user/mo) vs Microsoft Teams ($6–$12.50/user/mo via Microsoft 365) — see which team communication tool is cheaper and better for your organization.
| Tool | Free Tier | Standard Tier | Premium Tier | Pricing Model |
|---|---|---|---|---|
| Slack | Free | $6.25/user/mo | $12.50/user/mo | Per user per month |
| Microsoft Teams | Free | $6/user/mo | $12.50/user/mo | Per user/month (via Microsoft 365) |
Pricing current as of April 2026. Slack and Teams have nearly identical pricing. The real difference is bundling: Teams is bundled with Microsoft 365, while Slack is standalone.
| Plan | Per User/Month | Cost for 10 Users | Best For |
|---|---|---|---|
| Free | $0 | $0/month | Small teams, testing, side projects |
| Pro | $6.25/mo | $62.50/month | Growing teams, message search, unlimited integrations |
| Business+ | $12.50/mo | $125/month | Large teams, advanced admin controls, full message history |
| Enterprise Grid | Custom | Custom | Enterprise, custom security, SSO, compliance |
| Plan | Per User/Month | Cost for 10 Users | Includes |
|---|---|---|---|
| Teams Free | $0 | $0/month | Teams only (60 min meeting limit, 100 message search history) |
| Microsoft 365 Business Basic | $6/mo | $60/month | Teams + Word, Excel, PowerPoint online + 1 TB OneDrive |
| Microsoft 365 Business Standard | $12.50/mo | $125/month | Above + Outlook + full desktop Office apps |
| Microsoft 365 Business Premium | $20/mo | $200/month | Above + advanced security, device management |
Key difference: Slack prices are for Slack alone. Microsoft Teams pricing includes Office apps (Word, Excel, PowerPoint, Outlook) bundled with Teams, making it better value if you need productivity apps.

10 users × $12.50/mo = $125/month ($1,500/year)
Teams + Word, Excel, PowerPoint, Outlook, 1 TB OneDrive per person. You get email, docs, spreadsheets, storage all included.
Same price, but Microsoft gives you more: Both $1,500/year at the top tier.
The real question isn't price — it's whether you already use Microsoft 365 (in which case Teams is included) or prefer Slack's ecosystem and integrations. If you don't use Microsoft 365, Teams ends up cheaper due to bundling. If you're Slack-committed, Teams might feel expensive for the same chat-only cost.
Choose Slack if: You want best-in-class team chat. You rely on integrations (Zapier, GitHub, Salesforce, etc.). You already use non-Microsoft tools. You prefer a dedicated communication platform. You want the largest app ecosystem.
Choose Microsoft Teams if: You already use Microsoft 365 (Word, Excel, Outlook). Teams is included, so you get it free with your subscription. You need seamless Office app integration. You want email, chat, and docs in one ecosystem. You're in an enterprise locked into Microsoft.
Key insight: Pricing is identical at $12.50/user. The decision comes down to ecosystem: if you're in Microsoft 365, Teams is unbeatable value (it's free). If you're not, Slack offers superior integrations and UX for the same price. Most startups prefer Slack for its flexibility; enterprises often prefer Teams because Microsoft 365 is already there.

Slack Free: Unlimited channels, direct messages, 90 days message history, basic integrations. No time limit on calls.
Teams Free: Teams + limited calls (60 min per call), limited message search, limited meeting duration. More restrictions than Slack.
Slack, by a wide margin. Slack has 2,000+ integrations via Zapier and native apps. Teams has 500+ native integrations but fewer third-party options. If integrations matter to you, Slack wins.
Teams. Slack's native video calling is limited on the free tier. Teams offers full-featured video conferencing (up to 300 participants) across all tiers, matching Zoom quality.
Yes, some companies use both. Slack for community/culture, Teams for formal meetings + Office collaboration. But it adds cost and complexity. Most pick one for the entire organization.
