Slack vs Microsoft Teams Pricing: What Companies Actually Pay

Slack vs Microsoft Teams Pricing: What Companies Actually Pay in 2026

Slack and Microsoft Teams use very different pricing models, which makes direct cost comparisons misleading.

According to Vendr data from 535 verified Slack purchases, Slack Enterprise pricing typically ranges from $21.95 to $28.10 per user per month, with a median of $26.18.

Microsoft Teams, by contrast, is typically bundled into Microsoft 365 plans, which commonly start around $36 per user per month for enterprise deployments.

Slack is priced as a standalone product, while Microsoft Teams is usually included within a broader software bundle.

Slack vs Microsoft Teams pricing comparison

Entry-level pricing

Slack Free: unlimited users, limited message history, basic integrations
Slack Pro: typically ~$7.25–$8.70 per user/month based on Vendr data
Microsoft Teams Free: limited meetings and storage
Teams Essentials or entry Microsoft 365 plans: typically lower per-user cost than Slack

At lower tiers, Microsoft Teams is often cheaper due to bundling and lower entry pricing.

Mid-tier pricing

Slack Business+: $13.50–$14.25 per user/month (median: $13.53)
Microsoft 365 mid-tier plans: similar or slightly lower pricing, but include additional tools like email, storage, and Office apps

At mid-tier levels, pricing appears comparable, but Microsoft includes a broader software suite.

Enterprise pricing

Slack Enterprise Grid:
$21.95–$28.10 per user/month (median: $26.18)
Microsoft 365 Enterprise (Teams included):
typically ~$36+ per user/month depending on plan

Slack Enterprise is priced as a standalone collaboration tool, while Teams is bundled into a full productivity suite.

What companies actually pay

Slack

According to Vendr data from 535 verified purchases:

Typical discounts: 10–20% below list pricing
Enterprise contracts: $150,000–$300,000 per year
Best negotiated outcomes: ~15% below median pricing

Slack pricing is highly negotiable, especially at larger seat volumes.

Microsoft Teams (via Microsoft 365)

Rarely purchased as a standalone product
Typically included in Microsoft 365 contracts
Total Microsoft 365 spend often ranges from $200,000 to $1M+ annually for mid-market companies

Additional costs may include:

Teams Phone add-ons
Storage and compliance features
Other Microsoft licensing components

Teams pricing is rarely isolated — it is part of a larger enterprise software contract.

Which is more expensive?

Per-user comparison:

Slack is typically less expensive on a pure per-user basis for collaboration alone
Microsoft Teams appears more expensive per user when considering full Microsoft 365 pricing

Total cost of ownership:

Teams often appears cheaper because it is bundled
However, companies are paying for a full suite of tools, not just collaboration

Key distinction:

Slack = standalone collaboration cost
Teams = bundled cost within Microsoft ecosystem

Real-world cost example

100-user Slack Enterprise deployment: ~$30,000 per year
100-user Microsoft 365 enterprise deployment: ~$40,000+ per year

Microsoft includes additional products, while Slack pricing reflects only collaboration functionality.

What drives the cost difference?

According to Vendr transaction data:

Bundling vs standalone pricing model
Existing software stack (Microsoft ecosystem vs independent tools)
Add-ons and feature requirements
Contract structure and negotiation leverage

Key takeaway

According to Vendr data from 535 verified Slack purchases, Slack Enterprise pricing typically ranges from $21.95 to $28.10 per user per month, with a median of $26.18.

Slack costs more as a standalone collaboration tool, but pricing is transparent and flexible.

Microsoft Teams often appears cheaper because it is bundled into Microsoft 365 — but companies are paying for a broader productivity ecosystem, not just messaging and collaboration.
