How do you calculate security awareness coverage?

Divide users who completed required training by total in-scope users and multiply by 100. With 940 of 1,020 users complete, coverage is 92.16%, leaving a 5.84-point gap to a 98% target.

What is a good security awareness completion rate?

Mature programs target 95% or higher, with many aiming for 98% before an audit. The example's 92.16% is solid but short of the 98% target, so roughly 60 more completions are needed to close the gap.

What does the gap-to-target tell me?

It's the number of percentage points between current coverage and your goal. Here the 5.84-point gap, against 1,020 users, translates to about 60 people who still need to complete training.

Who should be in the awareness scope?

Everyone with access that an attacker could exploit: full-time staff, shift operators, and often contractors. The 1,020 total here should include every user the policy requires to train, or coverage will look artificially high.

How often should awareness training be refreshed?

Most programs require annual completion with periodic phishing simulations in between. Track coverage continuously through the cycle rather than only at year-end, so you can close the gap before the deadline.

Coverage vs phishing click rate, which matters more?

They measure different things. Coverage shows who completed training; click rate shows whether it worked. A high coverage with a high click rate means the training exists but isn't changing behavior.

Security Awareness Coverage Calculator

Security awareness coverage measures the share of your in-scope workforce that has completed required security training, and how far that sits below your target. Manufacturing security and compliance teams track it because the plant floor, contractors, and shift workers are exactly the population that phishing and social-engineering attacks aim at, yet they are the hardest to get through training. A single percentage makes coverage auditable against frameworks and easy to report to leadership, while the gap-to-target shows precisely how many more completions you need. It turns a vague we should train people into a concrete, trackable program metric you can drive to closure.

What this calculator does

Calculate security awareness coverage for manufacturing and OT support users against a target completion rate.
Use it when tracking training for operators, engineers, maintenance, supervisors, vendors, and IT or OT support roles.
It computes the percentage of in-scope users who have completed required awareness training and the point gap to your target rate.

Formula used

Security awareness coverage = users completing required awareness ÷ total users in awareness scope × 100
Security awareness coverage gap to target = security awareness coverage - target awareness completion rate

Inputs explained

Users completing required awareness:
Total users in awareness scope:
Target awareness completion rate:

How to use the result

Use it to report training compliance and to track a campaign mid-cycle so you can close the gap before an audit deadline.
Coverage only measures completion, not behavior change, so high coverage does not by itself prove the workforce is phishing-resistant.
