It's the monthly report that answers the only question that actually matters: are we making money? A CVR compares three numbers, what you've earned from the client (value), what you've spent delivering the work (cost), and what you expected to spend (budget). The gap between those three tells you everything about the project's commercial health.</p><p>Every commercial manager in UK construction produces one. Most call it a CVR. Some call it a CVS (cost value summary), a commercial report, or a margin report. Whatever the label, the structure is the same: income on one side, cost on the other, margin in the middle, and a forecast that determines whether the project director sleeps well this month.</p><p>CVR is part of the <a href="/en/earned-value/definitions">earned value definitions glossary</a>. For how CVR connects to formal <a href="/en/earned-value/definitions/earned-value-management">EVM</a> metrics, see the <a href="/en/earned-value/definitions">earned value formulas page</a>.</p><h2 id="the-cvr-structure">The CVR Structure</h2><p>A CVR isn't complicated. It's a table that tracks three columns of numbers from start to finish.</p><pre class="ge-ascii-diagram ge-anim"> ┌──────────────────────────────────────────────────────────────┐ │ COST VALUE RECONCILIATION │ │ Period 6 – September 2025 │ ├──────────────────────────────────────────────────────────────┤ │ │ │ INCOME SIDE │ COST SIDE │ │ (What we've earned) │ (What we've spent) │ │ │ │ │ Contract value £14.0M │ Labour £2.1M │ │ + Variations £0.8M │ Materials £3.4M │ │ + CEs approved £0.4M │ Subcontractors £4.2M │ │ + Claims £0.0M │ Plant £0.9M │ │ ─────────────────────── │ Prelims £1.6M │ │ Total value £15.2M│ ──────────────────────── │ │ │ Total cost £12.2M │ │ │ │ ├──────────────────────────────────────────────────────────────┤ │ │ │ MARGIN │ │ Value - Cost = £15.2M - £12.2M = £3.0M │ │ Margin % = £3.0M / £15.2M = 19.7% │ │ │ │ FORECAST │ │ Forecast final value £15.8M │ │ Forecast final cost £12.9M │ │ Forecast final margin £2.9M (18.4%) │ │ Budget margin £2.5M (17.9%) │ │ Variance to budget +£0.4M │ │ │ └──────────────────────────────────────────────────────────────┘ </pre><p>The income side captures everything the client owes you, contract sum, approved variations, implemented compensation events, and pending claims. The cost side captures everything you've spent. The difference is your margin. Compare that margin against your tender budget and you know whether the project is winning or losing.</p><h2 id="how-cvr-and-earned-value-connect">How CVR and Earned Value Connect</h2><p>Here's something that took me years to articulate properly. CVR and <a href="/en/earned-value">earned value management</a> aren't competing frameworks. They're looking at the same project from different angles.</p><p>CVR asks: "Are we making money?" That's a commercial question.</p><p>EVM asks: "Are we delivering efficiently?" That's a performance question.</p><p>The data overlaps significantly:</p><div class="ge-table-wrap ge-anim"><table class="ge-table"><thead><tr><th>CVR Element</th><th>EVM Equivalent</th><th>Notes</th></tr></thead><tbody><tr><td>Value (earned to date)</td><td><a href="/en/earned-value/definitions/earned-value">Earned Value (EV)</a></td><td>CVR value = what client owes you. EV = what work is worth against budget. Similar but not identical.</td></tr><tr><td>Cost (spent to date)</td><td><a href="/en/earned-value/definitions/actual-cost">Actual Cost (AC)</a></td><td>Direct mapping. CVR cost = AC in EVM terms.</td></tr><tr><td>Budget</td><td><a href="/en/earned-value/definitions/planned-value">Planned Value (PV)</a></td><td>CVR budget = what you planned to spend. PV = what you planned to earn. Different viewpoints.</td></tr><tr><td>Margin</td><td>No direct equivalent</td><td>EVM doesn't track margin. It tracks efficiency.</td></tr><tr><td>Forecast final cost</td><td><a href="/en/earned-value/definitions/estimate-at-completion">EAC</a></td><td>CVR forecast = bottom-up estimate. EAC can be formula-driven or bottom-up.</td></tr></tbody></table></div><p>The real power comes from overlaying EVM metrics onto your CVR. A CVR tells you margin is eroding. <a href="/en/earned-value/definitions/cost-performance-index">CPI</a> tells you by exactly how much per pound. A CVR tells you the forecast is slipping. <a href="/en/earned-value/definitions/schedule-performance-index">SPI</a> tells you the rate of slippage and when it started.</p><p>I've worked with commercial teams who treat CVR and EVM as separate exercises, the QS does the CVR, the planner does the earned value. That's a waste. The data comes from the same source. Integrate them and you get a single report that shows margin, efficiency, and forecast in one place.</p><h2 id="worked-example-14m-nec4-option-a-monthly-cvr-with-evm-overlay">Worked Example: £14M NEC4 Option A Monthly CVR With EVM Overlay</h2><span class="ge-worked-label">Worked Example</span><div class="ge-callout ge-anim"><p><strong>Scenario:</strong> A £14M NEC4 Option A highway maintenance term contract in Yorkshire.

Either way, it's a conversation worth having at the monthly commercial review.</p></div><h2 id="the-cvr-as-a-commercial-weapon">The CVR as a Commercial Weapon</h2><p>A good CVR doesn't just report the past. It predicts the future.</p><p>The forecast section is where commercial managers earn their money. Forecasting final value means assessing every CE in the pipeline, implemented, quoted, notified, and anticipated. Forecasting final cost means knowing what's left to build and how much it'll actually cost, not how much you hoped it would cost six months ago.</p><p>On NEC4 Option C contracts, CVR becomes even more critical because of the pain/gain mechanism. The Contractor's share depends on the difference between final <a href="/en/earned-value/definitions/defined-cost">Defined Cost</a> (plus fee) and the target total of the Prices. Your CVR forecast is your best estimate of where that share calculation will land. Get it wrong and you're either overcommitting resources to a losing position or leaving money on the table.</p><h2 id="common-mistakes">Common Mistakes</h2><ol><li><strong>Overstating value, understating cost.</strong> The classic. Project directors want to see green numbers, so the CVR shows optimistic value recovery and conservative cost forecasts. By month 18, the gap between the CVR forecast and reality is £2M and nobody's surprised except the board. Be honest in your CVR or it's useless as a management tool.</li><li><strong>Not reconciling to the accounts.</strong> Your CVR cost figure should agree with the project's financial accounts. If the finance team says you've spent £8.2M and your CVR says £7.9M, one of you is wrong. That £300K gap is usually timing differences on accruals, but sometimes it's a cost you've forgotten to include. Reconcile monthly.</li><li><strong>Ignoring anticipated CEs.</strong> Some commercial managers only include implemented CEs in the forecast value. That's leaving money off the table. A good CVR includes a pipeline of CEs at various stages, implemented, quoted, notified, anticipated, each with a probability weighting. On NEC4, this is where disciplined <a href="/en/nec4/compensation-events">compensation event</a> tracking pays off.</li><li><strong>Static forecasts.</strong> A forecast that hasn't changed in three months is a forecast nobody's updating. Costs change. Scope changes. Risk profiles shift. If your CVR forecast final margin is identical to last month's, either you're incredibly lucky or you're not doing the work.</li></ol><div class="ge-product-note ge-anim"><p><strong>How Gather helps.</strong> Gather's AI reads your site diaries daily and maps progress against your cost-loaded programme, giving you accurate earned value data without manual spreadsheet updates. <a href="https://gatherinsights.com/contact">Book a demo</a> to see it working on a live NEC4 project.</p></div><h2 id="frequently-asked-questions">Frequently Asked Questions</h2><h3>What does CVR stand for in construction?</h3><p>CVR stands for Cost Value Reconciliation. It's the standard monthly commercial report on UK construction projects that compares the value earned from the client against the cost of delivering the work. The difference is the project margin. Some contractors use CVS (Cost Value Summary) or simply "the commercial report", the content is the same.</p><h3>How is CVR different from earned value management?</h3><p>CVR is primarily a commercial tool that tracks margin (value minus cost). <a href="/en/earned-value">Earned value management</a> is a performance measurement tool that tracks efficiency (how much value you're delivering per pound spent). CVR asks "are we making money?" while EVM asks "are we delivering efficiently?" The data overlaps substantially, and the best commercial teams integrate both into a single monthly report.</p><h3>How often should a CVR be produced?</h3><p>Monthly is the industry standard on most UK construction projects. The CVR typically aligns with the monthly payment assessment under the contract, on NEC4, that's the assessment day defined in Contract Data part one. Some fast-paced projects do four-weekly CVRs to match the NEC4 assessment cycle. Whatever the frequency, consistency matters more than precision.</p><h3>What should a good CVR forecast include?</h3><p>A good forecast covers both value and cost. On the value side: implemented variations and CEs, submitted quotations with probability weightings, anticipated CEs not yet notified, and any claims in progress. On the cost side: committed costs (subcontracts, material orders), forecast remaining costs by package, and a realistic assessment of risk allowances. The forecast should change every month as new information emerges. A static forecast is a dead forecast.</p></article></div>
