What Is a Cost Performance Report (CPR) in EVM?

<div class="ge-article-wrapper"><article class="ge-article-body"><p>A Cost Performance Report (CPR) is the formal document that presents <a href="/en/earned-value">earned value</a> data, variances, and forecasts to project stakeholders. On US defence contracts, CPR has five standardised formats. On UK construction, it's typically adapted into a monthly commercial report that integrates EVM with NEC4 contract administration.</p><p>This term is part of the <a href="/en/earned-value/definitions">earned value definitions glossary</a>.</p><h2>CPR Structure for UK Construction</h2><pre class="ge-ascii-diagram ge-anim">MONTHLY EVM REPORT STRUCTURE 1. EXECUTIVE SUMMARY CPI: 0.94 SPI: 0.88 EAC: £32.4M (BAC £30M) Key risks and actions 2.

MANAGEMENT ACTIONS Corrective actions underway Recovery plan status Risks and opportunities</pre><h2>NEC4 Integration</h2><p>The CPR should align with the NEC4 assessment cycle (clause 50). Key dates: assessment date, payment due date, next programme submission. The commercial manager typically produces the CPR within one week of the assessment.</p><h2>Common Mistakes</h2><ol><li><strong>Numbers without narrative.</strong> A CPI of 0.91 means nothing without explaining why and what you're doing about it.</li><li><strong>Inconsistent reporting periods.</strong> Use the same cut-off every month.</li><li><strong>Not tailoring for the audience.</strong> The project board needs headlines. The commercial team needs detail.</li></ol><div class="ge-product-note ge-anim"><p><strong>How Gather helps.</strong> Gather generates monthly EVM reports automatically from your site diary data. <a href="https://gatherinsights.com/contact">Book a demo</a>.</p></div><h2>Frequently Asked Questions</h2><h3>How often should CPRs be produced?</h3><p>Monthly, aligned with the NEC4 assessment cycle.
