## Formula

Line balance efficiency = Total work content ÷ (Number of stations × Longest station time) × 100; Balance delay = 100 − Efficiency

- Line balance efficiency = Total work content ÷ (Number of stations × Longest station time) × 100; Balance delay = 100 − Efficiency.
- Inputs used: Station 1 work content, Station 2 work content, Station 3 work content (optional), Station 4 work content (optional), Station 5 work content (optional), Station 6 work content (optional), Station 7 work content (optional), Station 8 work content (optional), and other shown inputs.
- Edge handling: Station 1 work content is required.; Station 1 work content cannot be negative.; Station 1 work content must be no more than 1000000000000.; Station 2 work content is required.; Station 2 work content cannot be negative..

## Inputs

- Station 1 work content
- Station 2 work content
- Station 3 work content (optional)
- Station 4 work content (optional)
- Station 5 work content (optional)
- Station 6 work content (optional)
- Station 7 work content (optional)
- Station 8 work content (optional)
- Your takt time (optional)

## Worked example: A five-station line

Efficiency compares the work content with the time the longest station forces on every station.
1. Start with Station 1 work content: 1.2, Station 2 work content: 0.9, Station 3 work content (optional): 1.4, Station 4 work content (optional): 1.1, Station 5 work content (optional): 0.8, Station 6 work content (optional): 0.
2. Apply the method: Line balance efficiency = Total work content ÷ (Number of stations × Longest station time) × 100; Balance delay = 100 − Efficiency.
3. Efficiency compares the work content with the time the longest station forces on every station.

## Common questions

### Where does this formula come from?

MIT OpenCourseWare 2.854 Introduction to Manufacturing Systems — throughput is output per unit of time, cycle time is run time divided by the units produced, line capacity is set by the slowest station, and balance efficiency compares total work content with the number of stations multiplied by the longest station time. See the source link on this page.

### What kind of calculation is this?

Total task time compared with the time every station is forced to take by the slowest one. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the measurements behind them are right. A measured result, an industry benchmark and an organisation's target are three different things; only the entered figures are used. The theoretical minimum station count ignores precedence between tasks, so a real line often needs more stations than it shows.

### How do I use the Line Balance Calculator?

Enter the required values for Station 1 work content, Station 2 work content, Station 3 work content (optional), Station 4 work content (optional), Station 5 work content (optional), and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Line Balance Calculator use?

Line balance efficiency = Total work content ÷ (Number of stations × Longest station time) × 100; Balance delay = 100 − Efficiency The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### Can the Line Balance Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this line balance calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
