Access Review Effort Calculator

Work out access review effort instantly with clear inputs, formula shown and shareable results.

About Access Review Effort Calculator

User access review effort is users times entitlements times seconds per decision, and the numbers get large fast: 3,000 users with 14 entitlements each is 42,000 decisions per cycle, over 230 hours at 20 seconds each. That arithmetic is why quarterly reviews degenerate into bulk approvals, and why role-based grouping and risk-based scoping matter more than reviewer diligence.

Formula

Review effort

decisions = users x entitlements; hours per cycle = decisions x seconds / 3600; annual = hours x cycles

Worked example

With the default values below, Access Review Effort Calculator returns Annual review effort of 933. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How can the decision count be reduced?

Review roles rather than individual entitlements, auto-approve unchanged low-risk access, and focus manual attention on privileged and segregation-of-duties conflicts.

What makes reviews ineffective?

Reviewer fatigue leading to blanket approval. If the average decision takes two seconds in practice, the control exists on paper only.
