Get an indicative estimate of the auditor effort for your SOC 2 Type 1 and Type 2 examination — based on the people in scope and the Trust Services Categories you include.
Security always included · 33 criteria
Estimates scale with the number of Trust Services Criteria in scope: Security is always included (33 common criteria); Availability adds 3, Confidentiality 2, Processing Integrity 5 and Privacy 18. A Type 2 report also requires an observation period — longer periods mean larger evidence samples, so 12-month reviews take a little more audit time than 3-month ones. Type 1 is point-in-time and unaffected.

Indicative only. SOC 2 has no fixed audit-time table — final effort is confirmed by Cianaa through scoping (systems, locations, subservice organisations, evidence maturity). Type 2 reports are typically renewed annually.
Unlike ISO certifications, SOC 2 has no international audit-time table. Effort is driven by three things: how many controls must be tested, how large and complex the in-scope system is, and whether the auditor tests design only (Type 1) or operating effectiveness over a period (Type 2).
People in scope
Everyone who operates, develops or supports the in-scope system — a practical proxy for how many processes, teams and control owners the auditor must cover.
Trust Services Categories
Security (the 33 common criteria) is mandatory. Each added category — Availability, Confidentiality, Processing Integrity, Privacy — adds criteria, controls and evidence to test.
Type 1 vs Type 2
Type 1 examines control design at a point in time. Type 2 also tests operating effectiveness across a 3–12 month observation period — more sampling, more evidence, more effort.
Please note: this calculator gives a planning guide, not a quote. SOC 2 effort varies with the number of in-scope systems and locations, use of subservice organisations (carve-out vs inclusive), and how audit-ready your evidence is. Contact us and we’ll confirm scope and a fixed-fee proposal.
Type 1 vs Type 2 at a glance
Type 1
Design, at a point in time
Opinion on whether controls are suitably designed as at a specific date
Faster to obtain — often the first report a growing company issues
Good for urgent customer or deal requirements
No observation period required
Type 2
Operating effectiveness, over a period
Opinion on whether controls operated effectively across an observation period (typically 3–12 months)
The report most enterprise customers ask for
Includes the auditor’s tests and results for each criterion
Usually renewed annually with a fresh period
SOC 2 duration — common questions
How long does a SOC 2 audit take end to end?
For a Type 1: mostly the auditor’s fieldwork and reporting — typically a few weeks elapsed. For a Type 2: add the observation period (3–12 months of your controls operating) before the audit and report can conclude. Many first-time companies choose a 3-month period, then move to annual 12-month periods.
Do we need all five Trust Services Categories?
No. Only Security is required. Add categories your customers actually rely on — Availability is common for SaaS; Confidentiality where sensitive business data is held; Processing Integrity for transaction processing; Privacy where you commit to handling personal information under your own notice.
Should we start with Type 1 or go straight to Type 2?
If a customer needs evidence quickly, a Type 1 gets a report in hand while your Type 2 observation period runs. If you have time, going straight to a Type 2 (often with a 3-month first period) avoids paying for two examinations.
Is this calculator’s estimate official?
No — there is no official SOC 2 audit-time standard. This is Cianaa’s indicative model: a base effort scaled by the people in scope, multiplied by the proportion of Trust Services Criteria you include, with Type 1 estimated at roughly 60% of Type 2 effort. Your formal proposal is confirmed through scoping. Also see our ISO audit duration calculator.
