Industrial Calculators
OEE, uptime and downtime, throughput, production capacity, rolled throughput yield and maintenance intervals.
Industrial
Downtime & Uptime Calculator
Uptime and downtime percentages, availability, and downtime cost — with the equivalent “nines”.
Uptime % = (period − downtime) ÷ period ×…
Also called uptime calculator · availability percentage
Industrial
Production Capacity Calculator
Maximum production capacity from machine hours and cycle time, and the capacity needed for a demand target.
Capacity = machines × hours × days × 60 ÷…
Also called plant capacity · capacity planning
Industrial
Machine Utilization Calculator
Machine (or resource) utilization: run time as a percentage of available time.
Utilization = Run time (hours) ÷ Availabl…
Also called equipment utilization · asset utilization
Industrial
Throughput Calculator
Throughput rate from work in progress and flow time using Little’s Law, and the WIP needed for a target rate.
Little's Law: WIP = throughput × flow time
Also called littles law calculator · flow rate
Industrial
Rolled Throughput Yield Calculator
Rolled throughput yield (RTY) across a multi-step process — the probability a unit passes every step defect-free.
RTY = Y₁ × Y₂ × … × Yₙ
Also called rty calculator · process yield multi step
Industrial
Scrap Rate Calculator
Scrap (reject) rate: scrapped units as a percentage of total units produced, and the cost of scrap.
Scrap rate = Scrapped units ÷ Total units…
Also called reject rate · waste rate
Industrial
MTBF & MTTR Calculator
Mean time between failures (MTBF), mean time to repair (MTTR) and availability from operating data.
MTBF = operating hours ÷ failures
Also called mean time between failures · mttr calculator
Industrial
Efficiency Calculator
Efficiency as output ÷ input × 100 — for machines, energy conversion, processes or work.
Efficiency = Useful output ÷ Total input …
Also called efficiency formula · machine efficiency
Key industrial formulas
| OEE | OEE = availability × performance × quality |
|---|---|
| Downtime & Uptime | Uptime % = (period − downtime) ÷ period × 100 |
| Production Capacity | Capacity = machines × hours × days × 60 ÷ cycle time × efficiency |
| Machine Utilization | Utilization = Run time (hours) ÷ Available time (hours) × 100 |
| Throughput | Little's Law: WIP = throughput × flow time |
| Rolled Throughput Yield | RTY = Y₁ × Y₂ × … × Yₙ |
| Scrap Rate | Scrap rate = Scrapped units ÷ Total units produced × 100 |
| MTBF & MTTR | MTBF = operating hours ÷ failures · Availability = MTBF ÷ (MTBF + MTTR) |
| Efficiency | Efficiency = Useful output ÷ Total input × 100 |
