Kos ini akan meningkat sedikit kerana aktiviti senggaraan berkala yang dilakukan & akibat peningkatan usia mesin yang digunakan. Walaubagaimanapun kos bagi senggaraan tidak berperancangan menunjukkan kos operasi akan meningkat dengan banyaknya akibat daripada terdapat banyak aktiviti sengaaraan yang tidak terancang yang mana mengakibatkan kehilangan kos yang lebih seperti kos buruh, masa dan sebagainya.
