Free Manufacturing Production Efficiency & OEE Calculator

See Where Your Factory Is Losing Time, Capacity and Good Output.

For manufacturers, plant managers, production managers, supervisors, QA teams and maintenance teams. Measure OEE, downtime, capacity utilisation, plan adherence, first-pass yield, scrap, rework and labour productivity.

Manufacturing performance toolkit

From Production Time to Good Saleable Output.

Production Dashboard

OEE, plan adherence, first-pass yield, scrap, rework, downtime and lost contribution in one model.

OEE Calculator

Availability × Performance × Quality.

Plan vs Actual

Production variance, adherence and recovery rate needed to meet plan.

Capacity Utilisation

Compare actual output with practical available production capacity.

Downtime & Lost Output

Convert breakdowns, waiting, changeovers and stoppages into lost output and GHS impact.

First-Pass Yield

Measure output that passed without rework and track operator-stage defect detection.

Scrap & Rework

Calculate scrap rate, rework rate and indicative cost of poor quality.

Labour Productivity

Measure good output per labour hour and direct labour cost per good unit.

Changeover Efficiency

Compare planned and actual changeover time and estimate lost output.

MTBF & MTTR

Measure breakdown frequency, repair time, PM compliance and repeat failures.

Manufacturing Production Efficiency & OEE Toolkit

See Where Production Time, Capacity and Good Output Are Being Lost.

For factories and manufacturing teams that need to measure OEE, downtime, plan adherence, capacity utilisation, first-pass yield, scrap, rework, labour productivity and maintenance performance.

Current production context

My Production Line

Set line, product, output unit and planning period once.

Complete production view

Measure the shift, day, week or month in one place.

Enter planned production time, actual run time, output and quality. The dashboard converts them into operational KPIs that management can act on.

Time & production plan

Planned production time hours Actual run time hours Ideal production rate good output units per hour at target speed Planned output units Total actual output good + scrap + rework Good output first time units that passed without rework Final good output good output after permitted rework

Losses

Scrap / rejected output units Reworked output units Changeover / setup time hours Breakdown downtime hours Material shortage / waiting hours Power / utility stoppage hours Other production stoppage hours

Commercial impact

Contribution per good unit GHS, optional Direct production cost per unit GHS, optional

Overall Equipment Effectiveness

Calculate OEE from availability, performance and quality.

OEE shows how much of the planned production opportunity became good output at the expected production rate.

Planned production time hours Actual run time hours Ideal production rate units per hour Total output units Good output units

Production plan vs actual

See how closely actual production followed the approved plan.

Planned output Actual output Time remaining in period hours, optional Current production rate units per hour, optional

Capacity utilisation

Measure how much of available practical production capacity is actually being used.

Number of machines / lines Available shifts Hours per shift Rated output per machine-hour Planned downtime / maintenance hours Actual output

Downtime & lost output

Translate production stoppages into lost capacity and lost contribution.

Planned production time hours Breakdown downtime hours Changeover / setup hours Material / labour waiting hours Power / utility stoppage hours Other stoppage hours Expected production rate units per hour Contribution per unit GHS

First-pass yield

Measure how much output was right the first time.

Total units produced Units good first time Units reworked Units scrapped / rejected Defects caught by operator Defects caught later by QA

Scrap & rework

See the operational and financial cost of poor quality.

Total output Scrap / rejected units Reworked units Material cost per unit GHS Labour + machine cost per unit GHS Average additional rework cost per reworked unit GHS

Labour productivity

Measure output created from the labour hours used.

Number of production employees Hours worked per employee Good output produced Total direct labour cost GHS, optional

Changeover efficiency

See what excess setup and changeover time costs production.

Planned changeover time minutes Actual changeover time minutes Normal production rate units per hour Contribution per good unit GHS

Maintenance performance

Calculate MTBF, MTTR and maintenance response performance.

Total operating time hours Number of breakdowns Total repair downtime hours Preventive maintenance tasks due Preventive maintenance tasks completed on time Repeated failures of same cause

Why this matters

High Output Does Not Always Mean High Production Efficiency.

A factory can produce a large quantity and still lose money through downtime, slow running, changeovers, scrap and rework. OEE helps separate those losses into availability, performance and quality.

The toolkit also converts operational losses into output and financial impact, which makes production performance easier for both operations teams and management to understand.
