Microsoft Planner vs Smartsheet 2026: M365 Native vs Spreadsheet Platform

TL;DR: Microsoft Planner vs Smartsheet in 2026

Microsoft Planner is better when your organization is already paying for Microsoft 365 and wants task management embedded natively in Teams, SharePoint, and Outlook — accepting the Plan 1 upgrade at $10/user/month for Gantt and basic dependencies. Smartsheet is better when your team thinks in spreadsheet grids, needs flexible automation across complex data models, and wants cross-sheet reporting and formula-based rollups at $9/user/month Pro — without requiring an underlying Microsoft subscription. GanttFather is the third option when you need Gantt-first scheduling with free critical path and dependencies — without per-seat pricing or an ecosystem lock-in.

When Microsoft Planner is the better choice

For organizations already subscribed to Microsoft 365 Business Basic or higher ($6/user/month), Planner is available at no additional cost in its base form. Planner Plan 1 at $10/user/month adds Timeline (Gantt), task dependencies, project goals, sprints, and backlogs — bringing the effective per-user cost to $16/user/month including M365. Smartsheet Pro at $9/user/month is nominally cheaper on the plan price alone, but for M365 organizations, Planner Plan 1 delivers Gantt and dependencies inside a platform the team already uses, without the procurement overhead of a new vendor.

Planner’s Teams integration is its clearest advantage over Smartsheet. Tasks assigned in Planner appear in Teams activity feeds, Microsoft To Do, and project plan tabs within Teams channels — all within the same identity boundary the organization uses for everything else. Smartsheet has a Teams connector, but it is a third-party integration rather than a native embedding. For organizations where Teams is the single hub for communication and collaboration, Planner keeps project tasks in the same window as all other work.

Planner also suits iterative software teams better than Smartsheet. Planner Plan 1 includes sprints, backlogs, and task history — features aimed at Scrum and agile workflows that Smartsheet’s grid-first model was not built for. If your team runs sprints alongside traditional project tracks, Planner handles both within a single M365 context.

Pick Microsoft Planner if: your organization is deeply embedded in Microsoft 365, you communicate through Teams, and you need lightweight sprint management or Gantt at a plan price that bundles into existing M365 spending.

When Smartsheet is the better choice

Smartsheet’s grid view is its defining strength. The interface mirrors Excel closely enough that operations managers, finance leads, and business analysts can navigate it without project management training — and cross-sheet formulas, conditional formatting, and cell-level data validation work in ways that feel native to spreadsheet users. Microsoft Planner’s interface is clean and modern but is built around a task card model, not a grid — business users who live in spreadsheets will find Smartsheet’s layout more familiar.

Automation is Smartsheet’s second major advantage. The Pro plan at $9/user/month includes 250 automated actions per month — approval requests, conditional alerts, status-based row moves, and deadline notifications, all without writing code or configuring a separate workflow tool. Microsoft Planner has no native automation at any plan tier; teams that need automation in the Microsoft stack must configure Power Automate separately, adding complexity and a distinct licensing consideration. For operations or compliance teams that need workflow automation without involving IT, Smartsheet Pro’s included automations are a practical advantage over Planner’s complete absence of them.

Smartsheet Business at $32/user/month adds cross-sheet reporting, Timeline view (the fuller Gantt experience), workload tracking, and unlimited automations. For project management offices running multiple overlapping projects, the consolidated reporting across sheets is a capability Planner cannot match at any tier — Planner’s reporting stays within a single plan rather than aggregating across projects.

Pick Smartsheet if: your team works in spreadsheet-style grids, needs automation included in the base plan, and values cross-sheet formula reporting for operational data that spans multiple projects or departments.

Pricing reality check

For a 10-person team needing Gantt and dependencies, here is the annual cost:

• Microsoft Planner Plan 1: $10 × 10 users × 12 months = $1,200/year (plus required M365 subscription; M365 Business Basic at $6/user/month adds $720/year for non-M365 organizations, total $1,920/year). No automation layer at any Planner tier.
• Smartsheet Pro: $9 × 10 users × 12 months = $1,080/year. Includes Gantt and dependencies, 250 automations/month. No critical path, no Timeline view (that requires Business+ at $32/user/month).
• Smartsheet Business: $32 × 10 users × 12 months = $3,840/year. Adds Timeline view, workload tracking, and unlimited automations. Still no critical path.

On plan price alone, Smartsheet Pro ($1,080/year) is slightly cheaper than Planner Plan 1 ($1,200/year) for basic Gantt and dependencies. However, Planner requires M365 underneath, so for non-M365 organizations the effective Planner cost is $1,920/year. Planner’s key advantage for M365-native teams is bundled cost; Smartsheet’s key advantage is 250 automations per month included without a separate tool. Critically, neither Planner nor Smartsheet offers native critical path calculation at any price — a capability that must come from a different product entirely.

Where Planner and Smartsheet both fall short — the Gantt-first gap

Both tools treat the Gantt chart as a paid tier feature and neither offers critical path at any price point. Microsoft Planner withholds Gantt and dependencies from its bundled M365 tier, requiring a Plan 1 upgrade — and critical path is simply absent across all Planner tiers. Smartsheet Pro includes Gantt but lacks the fuller Timeline view (available only at Business, $32/user/month) and has no critical path calculation at any tier. Both platforms charge per seat, meaning a 20-person team pays twice as much as a 10-person team even if only three people are active project planners. Teams that plan primarily by Gantt chart and need critical path as a standard scheduling tool — not a premium feature or a separate product — will find both Planner and Smartsheet require either meaningful compromise or a move up to a more expensive tier.

The third option: GanttFather

GanttFather treats Gantt, dependencies, and critical path as baseline features, not upsell tiers. The free tier includes your first project with 2 editor seats and unlimited free viewers and guests — plus all four dependency link types (FS, SS, FF, SF with lag), critical path, Kanban, Excel round-trip import/export, and a native MCP server so AI agents like Claude and Cursor can read and update schedules directly. There is no per-seat fee and no Microsoft 365 prerequisite — extra projects you own are $5/month each ($30/year, 50% off) and every feature stays included, so pricing grows with the projects you own, never with headcount. Viewers and guests are always free, and editing a project someone else owns costs nothing. For teams that want Gantt-first planning with critical path at no additional cost, GanttFather removes the per-seat and ecosystem barriers that both Planner and Smartsheet impose.

FAQ

Does Smartsheet have a free plan?

No. Smartsheet has no free tier — only a 30-day trial with no credit card required. After the trial, the minimum paid plan is Pro at $9/user/month (annual). Microsoft Planner is included in Microsoft 365 subscriptions at no extra charge, but only for organizations already paying for M365. Neither tool is free for an organization starting fresh with no existing subscriptions.

Does Microsoft Planner have automations?

No. Microsoft Planner has no native automation or rules engine at any plan tier. Teams that need workflow automation in the Microsoft 365 stack must configure Microsoft Power Automate separately — a distinct tool with its own interface and licensing. Smartsheet Pro at $9/user/month includes 250 automated actions per month natively, covering approval requests, conditional alerts, and status-based row moves without a separate tool.

Does either Planner or Smartsheet have critical path?

No — neither tool offers native critical path calculation. Microsoft Planner does not list critical path as a feature at any tier. Smartsheet also does not offer critical path analysis at any plan tier. For critical path within the Microsoft ecosystem, the feature appears in Microsoft Project at Plan 3 ($30/user/month annual). Outside the Microsoft stack, GanttFather includes critical path on the free tier.

How much does Smartsheet cost vs Microsoft Planner for a 10-person team?

Smartsheet Pro: $9 × 10 × 12 = $1,080/year (Gantt + dependencies + 250 automations/month). Planner Plan 1: $10 × 10 × 12 = $1,200/year plus M365 subscription. For M365-native teams, the effective Planner Plan 1 add-on cost is $1,200/year versus Smartsheet Pro at $1,080/year — Smartsheet is slightly cheaper while also including automations. For non-M365 teams, adding M365 Business Basic brings the total Planner stack to $1,920/year versus Smartsheet’s $1,080/year.

Can Smartsheet connect to Microsoft Teams?

Yes. Smartsheet has a Microsoft Teams integration that lets users view and update sheets inside a Teams channel tab. However, it is a third-party connector — Smartsheet rows do not appear in Teams activity notifications or Microsoft To Do the way Planner tasks do. For a deeper Teams-native experience, Planner is the stronger choice. For broad integration with non-Microsoft tools (Jira, Salesforce, Slack), Smartsheet’s 200+ integrations give it more flexibility than Planner’s Microsoft-centric ecosystem.

Which is easier to learn — Microsoft Planner or Smartsheet?

Both are accessible, but for different user types. Microsoft Planner’s Board and Grid views are intuitive for anyone familiar with Kanban or basic task lists. Smartsheet’s grid view is easier for users who already work in Excel — formulas, row structures, and column types feel familiar. Users who don’t work in spreadsheets may find Smartsheet’s data model slightly more complex than Planner’s task card approach. For teams with a mix of both profiles, Planner’s integration with Teams may provide more contextual guidance during onboarding.
