Annual Cost by Team Size

Team Size Slack Pro ($8.75/user) Teams Essentials ($4/user) Discord (Free)
5 users $525/year $240/year $0/year
10 users $1,050/year $480/year $0/year
25 users $2,625/year $1,200/year $0/year
50 users $5,250/year $2,400/year $0/year
100 users $10,500/year $4,800/year $0/year
⚠️ Discord's Hidden Costs: While Discord is free, it lacks business-critical features. You'll need separate tools for SSO ($3-8/user/mo), compliance auditing, file management (limited to 25MB uploads), and professional integrations. For many teams, the "free" Discord ends up costing more in workarounds than a paid Slack or Teams plan.

Verdict: Which Should You Choose?

Choose Slack If:

  • Your team uses many SaaS tools and needs deep integrations
  • You need Workflow Builder for automation
  • Budget is less important than functionality
  • You're a tech/startup company where Slack is the standard

Choose Microsoft Teams If:

  • You already pay for Microsoft 365
  • Your team uses Office apps daily (Word, Excel, PowerPoint)
  • You need large video meetings (100-300 people)
  • Budget is a primary concern

Choose Discord If:

  • You're a small startup (< 10 people) with zero budget
  • Your team is young and comfortable with Discord
  • You don't need SSO, compliance, or enterprise features
  • You value always-on voice channels for quick collaboration
💡 Our Recommendation: For most professional teams, Microsoft Teams offers the best value at $4/user/month (or free with Microsoft 365). Slack is worth the premium if you need its extensive integrations. Discord is great for bootstrapped startups but becomes a liability as you scale and need business features.
