The planned timeline for replacing aging IT hardware across an organization. A defined refresh cycle keeps devices performant and secure while allowing IT to plan procurement requirements in advance.
Why Refresh Needs to Be Planned
The device refresh cycle is the schedule on which an organization replaces its hardware. Every device has a useful life, typically three to five years, depending on device type, workload, and vendor support timeline. The refresh cycle is the plan for managing that lifecycle predictably rather than reactively.
Organizations without a defined refresh cycle end up replacing devices when they fail, when complaints reach a threshold, or when an application can no longer run on the hardware. That approach is expensive, emergency replacements cost more than planned ones. It's disruptive. And it creates security risk, because older devices running unsupported operating systems stop receiving security patches.
Why Device Age Matters
The performance and security case for refresh is concrete. A four-year-old PC experiences 53% more security incidents than a device in its first year (Wipro). This is partly hardware deterioration and partly the vendor support timeline: once a device's OS reaches end-of-support, patches stop.
The looming Windows 10 end-of-support deadline is a live example at scale. Organizations that haven't tracked device age and planned refresh cycles are facing a scramble to replace devices that will lose security support, with no budget set aside and no procurement timeline established.
Typical Refresh Timelines by Device Type
Laptops and desktops: three to four years for power users (developers, designers, data analysts), four to five years for general office use. Mobile phones: two to three years, aligned to carrier cycles and OS support timelines. Servers: five to seven years, depending on workload. Network equipment: five to seven years for switches and routers.
DaaS and the Refresh Problem
Device-as-a-Service turns refresh into a contractual commitment rather than an ad hoc decision. Organizations that lease devices through a DaaS agreement bake the refresh cycle into the contract: at a defined interval, the provider swaps aging hardware for new devices as part of the subscription. The procurement and logistics burden of refresh moves to the provider, and the budget spike becomes a predictable monthly cost.
Budgeting for Refresh
A planned refresh cycle makes IT hardware costs predictable. If an organization has 400 devices on a four-year cycle, that's 100 replacements per year. At an average cost of $1,200 per device, that's $120,000 annually, a budget line item that can be planned and approved. The same 400 devices replaced reactively when they fail is unpredictable in timing and cost, and typically more expensive.
