You’re three weeks into a major product launch when the finance team drops the news: you’re 30% over budget. The work is getting done, deadlines are being met, but somehow the money disappeared faster than anyone expected. Sound familiar?<\/p>\n
This happens everywhere because teams track progress and spending separately \u2014 never connecting the two until it’s too late. Cost variance closes that gap. It measures the financial difference between planned spending and actual spending for completed work. It’s more than expense tracking. It shows whether your projects deliver value efficiently \u2014 or just burn cash.<\/p>\n
In this helpful article, you’ll learn the cost variance formula and see how to calculate it in practice. We\u2019ll explore why both positive and negative variances matter and what causes budget deviations. You\u2019ll also discover how the right work management platform can turn spreadsheet tracking into real-time financial intelligence.<\/p>\n"}]},{"main_heading":"Key takeaways","content_block":[{"acf_fc_layout":"text","content":"
Cost variance (CV) shows the financial gap between planned spending and actual spending at any point in your project. NASA’s official definition states that “Cost variance (CV) = Earned Value \u2013 Actual Cost”<\/a>, providing the foundational formula used across government and industry projects. It tells you whether you’re over or under budget \u2014 plain and simple.<\/p>\n Think of it this way: you established a project budget<\/a> of $50,000 for a marketing campaign. Halfway through, you’ve spent $30,000 but only completed 40% of the work. That gap between planned and actual spending reveals your cost variance \u2014 and signals you’re heading for trouble.<\/p>\n Cost variance does more than track expenses. It connects spending to progress, showing whether your project’s financially healthy or heading for trouble.<\/p>\n Track cost variance consistently and you’ll stop firefighting \u2014 you’ll manage proactively instead. Here’s what changes:<\/p>\nWhy tracking cost variance matters<\/h3>\n
