Preventive vs. Predictive Maintenance: Which One Saves You More Money?

Every business with equipment or facilities needs a maintenance strategy, but not all strategies are created equal. The two most common approaches are Preventive Maintenance (PM) and Predictive Maintenance (PdM)—but which one actually saves you more money?

At MARS, we specialize in optimizing maintenance strategies to reduce downtime, cut costs, and improve reliability. In this post, we’ll break down the key differences between PM and PdM, their pros and cons, and which approach is best for your business.

🔍 Preventive Maintenance (PM): The Basics

Definition: PM is a scheduled maintenance approach where inspections, repairs, and replacements are done at regular intervals, regardless of actual equipment condition.

✅ Pros:

✔ Reduces unexpected failures

✔ Helps with regulatory compliance

✔ Easy to implement and manage

❌ Cons:

✖ Can lead to over-maintenance, increasing costs

✖ Doesn’t detect unexpected failures early

✖ Requires manual scheduling & tracking

Example: Changing oil in a machine every 3 months whether it needs it or not.

🧠 Predictive Maintenance (PdM): The Future of Maintenance

Definition: PdM uses real-time data, sensors, and AI-driven analytics to predict failures before they happen. Maintenance is performed only when needed based on equipment condition.

✅ Pros:

✔ Minimizes downtime by predicting failures early

✔ Reduces unnecessary maintenance costs

✔ Extends equipment lifespan

❌ Cons:

✖ Requires technology investment (sensors, software)

✖ Needs skilled professionals to analyze data

✖ Best suited for companies with critical assets

Example: Using vibration sensors to detect early signs of a failing motor and servicing it before it breaks down.

💰 Cost Comparison: Which Saves More Money?

🔹 Preventive Maintenance:

  • Good for low-tech operations

  • Reduces unexpected breakdowns but may lead to unnecessary costs

🔹 Predictive Maintenance:

  • Higher upfront cost but long-term savings

  • Studies show PdM can reduce maintenance costs by 25-30% and cut downtime by up to 50%!

🔹 Hybrid Approach:

  • Many businesses combine PM & PdM for the best results

  • High-value equipment gets predictive maintenance, while low-risk assets follow preventive schedules
