As a business leader, you’re faced with a critical decision: build an internal IT department or partner with a managed service provider? This calculator gives you the real numbers you need to make an informed choice. Most executives underestimate the true cost of internal IT—it’s not just one person’s salary. To provide reliable, round-the-clock IT support that keeps your business running, you’ll need multiple full-time employees, comprehensive benefits packages, ongoing training, recruitment costs, equipment, and dedicated office space. Factor in the complexity of managing an entire department, staying current with rapidly evolving technology, and ensuring coverage during vacations and sick days, and the total investment often exceeds $400,000-600,000 annually. This calculator reveals these hidden costs using your actual business parameters, then compares them against professional managed services that deliver enterprise-level support, cutting-edge security, and 24×7 monitoring—often at a fraction of the internal cost. Use this tool to see the real financial impact of each option, so you can make the smartest decision for your business’s future growth and operational efficiency.
