How Auth0 prices by monthly active users, why the B2B model costs nearly four times B2C at the same volume, and the add-ons that stack on top.
The short answer
Auth0 starts at USD 35 a month for B2C Essentials and USD 150 for B2B Essentials, both at 500 monthly active users, with a free plan up to 25,000. At 5,000 B2C users, Essentials is USD 350 a month, or USD 3,850 a year billed yearly at eleven times the monthly price.

Auth0 charges by monthly active users, and the plan you pick is only half the price. The other half is which user tier you land in and whether your app is B2C or B2B. The same 5,000 users cost USD 350 a month on B2C Essentials and USD 1,300 on B2B Essentials.
This guide uses the price tables Auth0 publishes, shows how the tiers step, and flags the add-ons that make a bill larger than the plan price.
Prices below were recorded on 17 October 2026. The headline figure is the lowest price you can get for that plan. Check the official page before you buy, because vendors change prices without notice.

How billing works
Auth0 charges by monthly active users, and tiers are stepped and not metered, so crossing from 5,000 to 7,500 users is a fixed jump. B2B pricing assumes organizations, enterprise SSO and domain verification. Above 20,000 to 30,000 users, several plan and model combinations become contact-sales only. Yearly billing is charged at 11 times the monthly price, which Auth0 describes as one month free, so about 8% off. Add-ons are real money: B2B enterprise SSO connections cost USD 100 a month each beyond the 3 included on Essentials or 5 on Professional, Enterprise MFA is USD 100 a month on B2B Essentials, machine-to-machine tokens are priced by tier, and Auth0 for AI Agents adds 50% to the base price.
The tier trap
The expensive upgrade is not a feature but the B2C to B2B switch. Add business customers who need their own organizations and enterprise SSO and the same 5,000 users go from USD 350 to USD 1,300 a month on Essentials, a 271% increase for identical volume. Enhanced attack protection and custom database connections are the feature trap, both starting on Professional.
Read this first. The auth0.com/pricing page could not be fetched directly. The full price tables (B2C and B2B base prices by user tier, free plan limits, add-on prices and the 11x yearly rule) were read on 17 October 2026 from Auth0's own llms-full.txt file, so spot-check a few figures on the pricing page. Plan prices shown are the B2C price at 5,000 monthly active users and not a per-unit rate, and the yearly figure is the monthly price times 11 divided by 12. The calculator shows only the 500 and 5,000 user tiers captured from the tables and monthly list prices. No 2026 buyer-paid Auth0 dataset was found, so no benchmark is shown. Auth0 has a blog post about upcoming pricing changes for the Customer Identity Cloud that is not summarized here. FusionAuth's USD 0 self-hosted price and WorkOS AuthKit being free are from vendor pages and third-party sources.

Five thousand users shows the cost of attack protection and of the B2B model at the same volume.
| Scenario | Cost per year | Against the headline |
|---|---|---|
| B2C Essentials, 5,000 monthly active users, billed yearly at 11 times monthly | USD3,850 | Headline price |
| Enhanced attack protection required, so B2C Professional at 5,000 users, billed yearly | USD11,000 | +USD 7,150 |
| Same 5,000 users but a B2B app, so B2B Essentials, billed yearly | USD14,300 | +USD 10,450 |
Compare the plans side by side. Where a cell says Check page, the vendor's pricing page was not specific enough for us to fill it in.
| Feature | Free | Essentials | Professional | Enterprise |
|---|---|---|---|---|
| Monthly active users | Up to 25,000 | Priced by tier from 500 | Priced by tier from 500 | Custom tiers |
| Starting price a month (B2C) | USD 0 | USD 35 | USD 240 | Custom |
| Starting price a month (B2B) | USD 0 | USD 150 | USD 800 | Custom |
| Enterprise SSO connections | 1 | 3 on B2B, USD 100 a month each extra | 5 on B2B, USD 100 a month each extra | Custom tiers |

Features we could not place by plan: Pro MFA and role-based access control, Enhanced attack protection, Custom database connections, 99.99% SLA and enterprise rate limits. Check the official page for which plan includes each one.
Pick it for prototypes and early products under 25,000 monthly active users.

Pick it if you need custom user and SSO tiers, a 99.99% SLA and enterprise rate limits.
Our view
Auth0 is a strong choice when identity is a hard requirement and you want it maintained by someone else. The free plan is unusually generous, and the cost comes from stepped tiers, the B2B model and add-ons. Check the model and the tier before you build a forecast.
You may be overpaying if
You are on the B2B model without using organizations, test accounts and bots push you up a user tier, or you bought the AI agents add-on before any team shipped something that needs it.
Yearly billing is charged at 11 times the monthly price, about 8% off. On B2B Essentials at 5,000 users that is USD 1,300 a year for a decision that costs nothing operationally.
B2C Essentials at 5,000 users is USD 350 a month against USD 1,300 on B2B. If your organizations feature is unused, you pay a 271% premium for a model you do not need.
Tiers step and do not meter, so test accounts, bots and seasonal traffic can push you a whole tier up. Keep development traffic in the development tenant that Essentials includes.
Each connection past the included 3 on B2B Essentials or 5 on Professional is USD 100 a month, up to 30. A promise of SAML for ten customers is USD 700 a month on Essentials.
Clerk publishes Pro at USD 25 a month including 50,000 monthly retained users. WorkOS AuthKit is reported as free, with SSO and SCIM charged separately.
Auth0 for AI Agents adds 50% to the base price. Keep it out of the initial contract until a team has shipped something that needs it.

If this vendor does not fit, these are the closest options and what they charge.
| Alternative | Starting price | Pick it when |

| Clerk Pro | USD25 per month, including 50,000 monthly retained users | Your volume is large but your identity needs are standard |
| WorkOS AuthKit | Free, with SSO and SCIM charged separately | You mainly need enterprise SSO for B2B customers |
| FusionAuth Community | USD0 self-hosted | You are willing to run and patch identity infrastructure yourself |
Identity cost follows product decisions. Selling to businesses changes the model, and the invoice changes before anyone in finance hears about it.
Bottom line. Start on the free plan, move to Essentials when you need MFA and roles, and check the B2C or B2B model before you forecast. Clean the user count and keep add-ons out of the first contract.
B2C Essentials starts at USD 35 a month and B2C Professional at USD 240, both at 500 monthly active users. B2B starts higher, at USD 150 and USD 800. Price rises with the user tier: at 5,000 users B2C Essentials is USD 350 a month and B2B Essentials is USD 1,300.
Yes, and it is generous. The Free plan covers up to 25,000 monthly active users with 1 tenant, 1 custom domain, 5 organizations, 1 enterprise connection, 3 admins, 1,000 machine-to-machine tokens, 1-day log retention and community support. No credit card is needed to sign up.
Auth0 does not publish an Enterprise price and quotes it through sales. Enterprise adds custom user and SSO tiers, a 99.99% SLA, enterprise rate limits and enterprise administration and support. Published plans also become contact-sales above 30,000 B2C users and 20,000 B2B users.
Auth0 publishes one standing discount: yearly billing at 11 times the monthly price, about 8% off. Beyond that the savings are structural: moving to the correct B2C or B2B model, cleaning test traffic out of the user count, and negotiating Enterprise tiers instead of buying add-ons one by one.
Yes, by about 8%. Yearly billing is charged at 11 times the monthly price, which Auth0 describes as one month free. At 5,000 B2C monthly active users, Essentials is USD 3,850 a year instead of USD 4,200, and B2B Essentials is USD 14,300 instead of USD 15,600.
FusionAuth's community edition is USD 0 if you self-host, which suits teams willing to run identity infrastructure. Clerk publishes Pro at USD 25 a month including 50,000 monthly retained users with graduated overage from USD 0.02. WorkOS AuthKit is reported as free, with SSO and SCIM priced separately.
