Compliance Gap Score Calculator

Work out compliance gap score instantly with clear inputs, formula shown and shareable results.

About Compliance Gap Score Calculator

A gap assessment counts requirements at three implementation states, and giving partial implementations half credit avoids both the optimism of counting them as done and the pessimism of counting them as absent. Multiplying the remaining work by an average effort per gap converts the percentage into a schedule, which is what determines whether an audit date is realistic.

Formula

Compliance and effort

compliance = (full + 0.5 x partial) / total; effort = (not implemented + 0.5 x partial) x days per gap

Worked example

With the default values below, Compliance Gap Score Calculator returns Weighted compliance of 73.7%. Change any input above and every figure here is recalculated in your browser.

Inputs used

Requirements in the frameworkminimum 1: 114
Fully implementedminimum 0: 72
Partially implementedminimum 0: 24
Effort per remaining gapminimum 0.1 days: 4 days

Results

Weighted compliance: 73.7%
Requirements not implemented at all: 18
Effort to close the gaps: 120.0 days
Audit readiness: Substantial work remaining

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, fees or charges or compounding frequency 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

Do all requirements carry equal weight?

No. Certification usually hinges on a subset of mandatory clauses, so a weighted assessment that reflects auditor emphasis is more predictive than a flat count.

Is documentation enough to count a requirement as implemented?

No. Auditors test evidence of operation over a period, so a written policy with no records of execution will be assessed as partial at best.
