CMRP Formulas – Complete Guide
1.1 RATIO OF REPLACEMENT ASSET VALUE (RAV) TO CRAFT-WAGE
HEADCOUNT - ✔️ RAV ($) / Craft-Wage Headcount

1.3 MAINTENANCE UNIT COST - ✔️ Total Maintenance Cost / Standard
Units Produced

1.4 STOCKED MAINTENANCE, REPAIR AND OPERATING MATERIALS (MRO)
INVENTORY VALUE AS A PERCENT OF REPLACEMENT ASSET VALUE (RAV)
- ✔️ [Stocked MRO Value ($) × 100] / Replacement Asset Value ($)

1.5 TOTAL MAINTENANCE COST AS A PERCENT OF REPLACEMENT ASSET
VALUE (RAV) - ✔️ [Total Maintenance Cost ($) × 100] / Replacement Asset
Value ($)

2.1.1 OVERALL EQUIPMENT EFFECTIVENESS (OEE) - ✔️ Availability (%) ×
Performance Efficiency (%) × Quality Rate (%)

2.1.1 (OEE) - Availability - ✔️ (Uptime Hrs × 100) / (Total Available Time
Hrs - Idle Time Hrs)

2.1.1 (OEE) - Uptime - ✔️ Total Available Time Hrs - [Idle Time Hrs + Total
Downtime Hrs]

2.1.1 (OEE) - Total Downtime - ✔️ (Hrs) = Scheduled Downtime Hrs +
Unscheduled Downtime Hrs

2.1.1 (OEE) - Performance Efficiency - ✔️ (%) = [Actual Production Rate
(units per hour) / Best Production Rate (units per hour)] × 100

2.1.1 (OEE) - Quality Rate - ✔️ (%) = [(Total Units Produced - Defective
Units Produced) / Total Units Produced] × 100

2.1.2 TOTAL EFFECTIVE EQUIPMENT PERFORMANCE (TEEP) - ✔️ TEEP
(%) = Utilization Time % × Availability % × Performance Efficiency % ×
Quality Rate %

, 2.1.2 (TEEP) - Utilization Time - ✔️ (%) = [Total Available Time Hrs - Idle
Time Hrs] / Total Available Time Hrs

2.1.2 (TEEP) - Availability - ✔️ (%) = Uptime Hrs / [(Total Available Time
Hrs - Idle Time Hrs)] × 100

2.1.2 (TEEP) - Uptime - ✔️ (Hrs) = Total Available Time Hrs - (Idle Time Hrs
+ Downtime Hrs)

2.1.2 (TEEP) - Downtime - ✔️ (Hrs) = Scheduled Downtime Hrs +
Unscheduled Downtime Hrs

2.1.2 (TEEP) - Performance Efficiency - ✔️ (%) = [Actual Production Rate
(units per hour) / Best Production Rate (units per hour)] × 100

2.1.2 (TEEP) - Quality Rate - ✔️ (%) = [(Total Units Produced - Defective
Units Produced) / Total Units Produced] × 100

2.2 AVAILABILITY - ✔️ (%) = {Uptime Hrs / [Total Available Time Hrs - Idle
Time Hrs]} x 100

2.2 AVAILABILITY - Uptime - ✔️ Total Available Time - (Idle Time +
Downtime)

2.2 AVAILABILITY - Downtime - ✔️ Scheduled Downtime + Unscheduled
Downtime

2.3 UPTIME - ✔️ Total Available Time - (Idle Time + Total Downtime)

2.4 IDLE TIME - ✔️ (Hrs) = No Demand (ND) + Administrative Idle Time
(AIT) = IT = ND + AIT

2.4 IDLE TIME - Percentage - ✔️ (%) = Idle Time Hrs / Total Available Time
Hrs = IT / TAT

2.5 UTILIZATION TIME - ✔️ (%) = [(Total Available Time Hrs - Idle Time
Hrs) / Total Available Time Hrs] × 100
