Preventive Maintenance vs Reactive Repairs: Which Costs More?

The Reactive Trap

"If it is not broken, do not fix it" sounds like fiscal responsibility. In IT maintenance, it is the opposite. Reactive repairs — fixing things after they break — cost 3-5x more than scheduled preventive maintenance in the long run. Here is why.

The Real Costs of Reactive Repairs

When a server goes down at 2 PM on a Tuesday, the costs go beyond the repair bill: lost employee productivity (50 people x 2 hours x ₹500/hr = ₹50,000), emergency technician call-out charges (₹2,000-₹5,000 premium over scheduled visit), rush-delivery of spare parts (₹1,000-₹10,000 premium), and damaged customer trust if the outage affects client-facing systems.

The Math of Preventive Maintenance

A scheduled quarterly maintenance visit for a server room costs ₹3,000-₹5,000. An emergency server repair costs ₹15,000-₹25,000 plus productivity losses. If preventive maintenance catches a failing power supply before it fails, you saved ₹20,000+ on that one component alone.

For a company with 50 laptops, 3 servers, and 10 networking devices: annual preventive maintenance cost is approximately ₹60,000-₹80,000 (quarterly visits + parts). Estimated annual reactive repair cost without PM is ₹2,00,000-₹3,50,000 (emergency repairs + productivity loss).

Beyond Direct Costs: The Hidden Benefits

• Extended asset life: Properly maintained equipment lasts 20-40% longer. A ₹80,000 laptop that lasts 5 years instead of 3 saves ₹32,000 in replacement costs.
• Fewer emergency situations: Fewer late-night calls, less weekend work, lower team burnout.
• Predictable budgeting: You know your annual maintenance cost vs unpredictable emergency expenses.
• Better compliance: ISO 27001 and audit frameworks expect documented maintenance schedules and records.

What to Preventive-Maintain vs What to Run to Failure

Preventive maintenance is worth it for: servers and critical infrastructure, UPS and power systems, network equipment (switches, routers, firewalls), air conditioning in server rooms, and any equipment where downtime costs > PM cost. Run-to-failure is acceptable for: mice and keyboards, monitors (unless specialized), and low-cost peripherals where replacement is cheaper than repair.
