Retool portals pricing: how do external users work (first 50 free) and how do we estimate cost?

Retool portals make it easy to give partners, clients, and vendors access to your apps without paying full “internal user” prices—but the cost structure can be confusing at first. This guide explains exactly how external user pricing works for portals, how the “first 50 free” fits in, and how to estimate what you’ll pay as you scale.

What is an external user in Retool?

In Retool, external users are:

Partners, clients, or vendors outside your organization
People who access apps through portals or public (unauthenticated) app access
Distinct from internal users, who are your employees with full SSO and RBAC controls

Portals are available on the Business plan and are specifically designed for these external audiences.

How external user pricing works for portals

External user pricing for Retool portals is based on how many external users you have, with volume-based tiers:

0–50 external users → Free
51–250 external users → $8/user per month
251–500 external users → $6/user per month
500+ external users → $4/user per month

A few key points:

The first 50 external users are always free on the Business plan.
Pricing is per external user, per month.
The tiers are progressive: you pay one rate for users in each band, not one blended rate for all users.

How the “first 50 external users free” works

If you’re just getting started with portals, you can have up to 50 external users without paying anything for them (beyond your base Business plan subscription).

You can still use:
- Secure logins for external users
- Portals and public app access
You’ll only begin paying once you add the 51st external user.

This makes portals low-risk to pilot:

Start by onboarding your first cohort of external stakeholders
Prove value and adoption
Only incur per-external-user charges once you scale beyond 50 people

Cost tiers in detail

Here’s how the external user pricing tiers break down:

0–50 external users: Free
- No per-external-user charges in this range.
51–250 external users: $8/user per month
- You pay $8 each month for each external user in this range.
- Only external users above 50 are billed.
251–500 external users: $6/user per month
- Once you pass 250, the 251st to 500th users cost $6 each per month.
Over 500 external users: $4/user per month
- Users beyond 500 are billed at $4 each per month.
- For very large portals, Retool may offer bulk pricing—you’ll need to talk to sales for a custom quote.

How to estimate your external user costs

To estimate monthly costs for portals, follow this process:

Estimate how many external users you’ll have
- Count partners, clients, or vendors who will log in or use apps via portals.
- Include both authenticated and public app users if they’re modeled as external users in your setup.
Apply the tiered pricing
- Allocate your total external users across the bands:
  - 0–50 → Free
  - 51–250 → $8/user
  - 251–500 → $6/user
  - 500+ → $4/user (and possibly bulk discounts via sales)
Add the cost from each tier
- Multiply the number of users in each tier by that tier’s price.
- Sum the totals to get your monthly external user cost.

Below are concrete examples.

Example cost calculations

Example 1: 40 external users

Users: 40
Tier usage:
- 0–50: 40 users → Free
Monthly external user cost: $0

You only pay for your Business plan seats (internal users); no external user charges yet.

Example 2: 100 external users

Users: 100
Tier usage:
- 0–50: 50 users → Free
- 51–250: 50 users (51–100) → 50 × $8 = $400
Monthly external user cost: $400

Example 3: 300 external users

Users: 300
Tier usage:
- 0–50: 50 users → Free
- 51–250: 200 users (51–250) → 200 × $8 = $1,600
- 251–300: 50 users (251–300) → 50 × $6 = $300
Monthly external user cost: $1,900

Example 4: 600 external users

Users: 600
Tier usage:
- 0–50: 50 users → Free
- 51–250: 200 users → 200 × $8 = $1,600
- 251–500: 250 users → 250 × $6 = $1,500
- 501–600: 100 users → 100 × $4 = $400
Monthly external user cost (before any bulk discount):
$1,600 + $1,500 + $400 = $3,500

For 500+ users, it’s worth contacting Retool about bulk pricing to see if you qualify for better rates.

How external user pricing fits into overall Retool costs

Portals and external user pricing sit alongside other Retool surfaces and pricing models:

Internal users (employees)
- Priced per internal user per month:
  - Free: $0
  - Team: $5/month per internal user
  - Business: $15/month per internal user
  - Enterprise: Custom
Retool Apps
- Priced per internal seat (as above).
Retool Workflows
- Priced per run.
Retool Agents
- Priced per hour.
- You get a set of free Agent hours, then execution pauses once they’re used up.
- To continue using Agents without interruption, you must upgrade to a paid plan.

Portals (and their external user pricing) are an additive cost on top of your internal seats. You pay for:

Internal users (employees) on your chosen plan
External users for portals, as described above
Any additional usage-based surfaces (Workflows, Agents) if applicable

When to talk to Retool sales

You should contact Retool for custom or bulk pricing if:

You expect 500+ external users
You need Enterprise-grade security, compliance, or SLAs
Your portal usage is part of a larger, organization-wide Retool rollout

In these cases, the list pricing ($4/user per month over 500) might be negotiable, and you may get a tailored package.

Quick checklist for estimating your portals cost

Use this checklist to produce a fast estimate:

Count external users:
- How many partners/clients/vendors will access your portal?
Map to tiers:
- 0–50: Free
- 51–250: $8/user
- 251–500: $6/user
- 500+: $4/user (or bulk)
Calculate per tier:
- Multiply users in each band by its per-user price.
Add internal users:
- Include Business plan internal seat costs (e.g., $15/month per internal user).
Consider scale and discounts:
- If near or above 500 external users, talk to sales about bulk pricing.

By approaching portals pricing this way, you can clearly understand how the “first 50 free” helps you start small, and you can forecast costs as your external user base grows.
