Trello Pricing in 2026: Plans, Per-User Math, and the 1,000-Run Automation Cap

How much does Trello cost? The short answer

As of October 11, 2026, Trello costs $0 on Free, $5 per user a month on Standard and $10 on Premium when billed annually ($6 and $12.50 billed monthly), and $17.50 per user a month on Enterprise, billed annually. Free is capped at 10 collaborators per Workspace. For anyone automating a board, the number to watch is not the seat price but the automation quota: 250 runs a month on Free, 1,000 on Standard and unlimited runs on Premium.

Prices and plan features come from Trello's pricing page, and the automation quotas from Atlassian's Trello support article on automation quotas and limits, both read October 11, 2026. The API limits come from Atlassian's Trello developer documentation, read the same day. Where we assume how a workload maps to runs, we say so.

Trello's four plans at a glance

Free includes unlimited cards, up to 10 boards per Workspace, unlimited Power-Ups and 10 MB per file. Standard adds unlimited boards, Trello's AI features, card mirroring, custom fields, advanced checklists, 250 MB per file and single-board guests. Premium adds Calendar, Timeline, Table, Dashboard and Map views, Workspace-level templates, admin and security features, observers and simple data export. Enterprise adds unlimited Workspaces, organization-wide permissions, multi-board guests, Power-Up administration and Atlassian Guard Standard for SSO. The Enterprise price shown is per user on the page's default estimate; Trello's estimator changes it with the number of users, so get a quote at your real headcount.

Runs vs operations: the two automation meters

Trello's built-in automation (the feature formerly sold as Butler) uses two quotas, and they are easy to confuse:

• An automation run is one trigger firing or one button press. "When a card is added to Inbound" counts as one run every time a card lands there.
• An operation is each action that run takes. A rule that sets a label and a due date uses two operations per run. Most actions use one; some, such as sorting a list, use several.

Both quotas are pooled across every board in the Workspace and reset on the first day of each month at midnight GMT. A single run can perform at most 20 actions and operations on every plan, and each automation email counts once per recipient, so emailing all six board members uses six of the email quota. Atlassian also limits runs per minute and the number of cards a single run can touch, without publishing those numbers.

Worked example: a 12-person service team on Standard

Trello lists quotas, not workloads, so here is one. A 12-person home services office tracks every job as a card. About 15 jobs a day come in, which is roughly 330 cards a month over 22 working days. The board runs four rules per card:

1. Card created: add the job checklist, assign the coordinator, set a due date (1 run, 3 operations).
2. Card moved to Scheduled: email the customer a confirmation (1 run, 1 operation, 1 email).
3. Card moved to Done: move it to the billing list and post a comment (1 run, 2 operations).
4. Due date reminder the day before (1 run, 1 operation).

The finding most Trello price lists miss: on Standard, the meter that breaks is runs, not operations. This team uses 12% of its operations but runs out of runs around the fourth week, and from then until the 1st the rules simply stop. There are two ways out. Pay $60 a month more for Premium (on annual billing, 12 users), which removes the run cap. Or cut one rule per card: three rules on 330 cards is 990 runs, which fits Standard with 10 to spare. That is free, but it leaves no room for a busy month, so if volume is growing, budget Premium.

Free is not an option for this team at all: it caps a Workspace at 10 collaborators, and its 250 runs would be gone in about four working days.

How Trello bills seats and guests

• Every Workspace member is billable, including admins.
• Guests on one board are free on Standard and up. A guest on more than one board in the Workspace becomes a multi-board guest and is billed at the member rate. If you invite clients to their own board, keep each client on one board.
• Downgrading keeps paid features until the end of the prepaid period; the Workspace then becomes a Free Workspace that can hold 10 boards.
• SSO costs extra below Enterprise. SAML single sign-on comes through Atlassian Guard, a separate subscription that starts at $4 per user a month. Enterprise includes Guard Standard.
• Discounts exist for nonprofits and education, and every Workspace can trial Premium free.

How Trello connects to AI and other software

Trello has four doors for automation, and a real build often uses more than one:

• Built-in automation for rules inside the board, metered by the quotas above.
• Power-Ups, unlimited on every plan, which link boards to Slack, Google Drive, Salesforce and 200+ other tools. Trello notes that some partner Power-Ups charge their own subscription.
• AI features on Standard and up: AI quick capture from email, Slack and Microsoft Teams, AI summaries and writing help, AI-generated checklists and boards. Trello's pricing page does not list a separate AI charge.
• The REST API and Trello's MCP server, which Trello describes as a way to connect Trello to any AI tool. This is the route for automation platforms, web forms and custom AI agents.

The API has its own ceiling, separate from the automation quota: 300 requests per 10 seconds per API key and 100 requests per 10 seconds per token, with a much tighter 100 requests per 900 seconds on the /1/members route. Over the limit, Trello returns a 429 error, and if one key collects more than 200 of those in a window, every request on that key is refused for the rest of the 10 seconds. A sync that checks 12 boards once a minute uses 12 requests a minute, nowhere near the limit. An AI agent that loops through every card on every board and looks up each member is the pattern that hits it, which is why builds should page through cards in bulk and cache member lookups.

Outside tools that act on Trello do not use your automation quota, but they bring their own meters. A Zapier task or a Make operation is billed by that platform, so before you move rules out of Trello to dodge the run cap, check how much Zapier costs at the same volume.

Trello or monday.com for an automated board?

Teams that outgrow Trello's Standard plan usually price monday.com next. The two meter automation differently: Trello counts runs and operations with an unlimited-runs Premium tier at $10 a user, while monday counts automation actions and integration actions per month and caps Standard at 250 of each. For the same 12 people, Trello Premium is $120 a month on annual billing; our monday.com pricing breakdown shows where monday's limits land for a similar intake workload. Both are usually one piece of a larger business process automation software stack, where the board sits between intake, scheduling, invoicing and customer messaging.

When does a team outgrow Trello?

Not at a seat count. These are the signals we see:

• The same job is typed into Trello, then again into the scheduling tool, then again into the invoice.
• Rules have grown past what one person understands, or a single process needs more than the 20 actions one run can perform.
• An AI step needs to read the job, decide something and write back, every time, without a person pressing a button.
• Customers or field staff need their own view, and multi-board guests are starting to cost as much as employees.

At that point Trello can stay as the board people look at while the work moves through a system built around it.

Who can build automations around Trello for a small business?

Start with Trello's own rules and Power-Ups; they are included and they cover a lot of a small team's work. Bring in a builder when the workflow has to leave the board: web forms and phone calls that create cards, an AI step that triages or drafts replies, or jobs that must flow into scheduling and accounting without retyping. SuperDupr builds that layer and leaves your Trello account as it is; we do not resell Trello seats. A Trello-centered workflow is an AI workflow automation project for us, published at $10,000 to $25,000, with most AI systems live in 2 to 4 weeks and ongoing support at $200 to $2,000 a month depending on volume. You own what we build. The first step is a free 30-minute strategy session. If you are still comparing what builders charge, our guide to AI automation pricing lays out the common pricing models.
