## Formula

Lead time = Order processing + Queue + Setup + Run + Move + Wait + Shipping time

- Lead time = Order processing + Queue + Setup + Run + Move + Wait + Shipping time.
- Inputs used: Run time, Setup and changeover time (optional), Order processing time (optional), Queue time before the work starts (optional), Move time between operations (optional), Wait time after the work (optional), Shipping time to the customer (optional).
- Edge handling: Run time is required.; Run time cannot be negative.; Run time must be no more than 1000000000000.; Setup and changeover time (optional) is required.; Setup and changeover time (optional) cannot be negative..

## Inputs

- Run time
- Setup and changeover time (optional)
- Order processing time (optional)
- Queue time before the work starts (optional)
- Move time between operations (optional)
- Wait time after the work (optional)
- Shipping time to the customer (optional)

## Worked example: An order from receipt to despatch

Every component is entered by you; nothing is added for queueing or shipping unless you enter it.
1. Start with Run time: 6, Setup and changeover time (optional): 1.5, Order processing time (optional): 2, Queue time before the work starts (optional): 16, Move time between operations (optional): 1, Wait time after the work (optional): 8.
2. Apply the method: Lead time = Order processing + Queue + Setup + Run + Move + Wait + Shipping time.
3. Every component is entered by you; nothing is added for queueing or shipping unless you enter it.

## 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?

Every element of elapsed time the user enters, added together, with the share spent on the work itself shown separately. 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. Elements are assumed not to overlap. Where they do, the total will overstate the elapsed time.

### How do I use the Production Lead Time Calculator?

Enter the required values for Run time, Setup and changeover time (optional), Order processing time (optional), Queue time before the work starts (optional), Move time between operations (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 Production Lead Time Calculator use?

Lead time = Order processing + Queue + Setup + Run + Move + Wait + Shipping time 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 Production Lead Time 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 production lead time calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
