## Formula

Capacity = ((Machines × Hours per shift × Shifts per day × Days in period) − Planned downtime) × Units per running hour

- Capacity = ((Machines × Hours per shift × Shifts per day × Days in period) − Planned downtime) × Units per running hour.
- Inputs used: Machines or lines running, Hours per shift, Shifts per day, Days in the period, Units one machine makes per running hour, Planned downtime in the period (optional).
- Edge handling: Machines or lines running is required.; Machines or lines running cannot be negative.; Machines or lines running must be no more than 1000000000000.; Hours per shift is required.; Hours per shift cannot be negative..

## Inputs

- Machines or lines running
- Hours per shift
- Shifts per day
- Days in the period
- Units one machine makes per running hour
- Planned downtime in the period (optional)

## Worked example: Four machines, two shifts, twenty days

Planned downtime is deducted only because it was entered; nothing is assumed.
1. Start with Machines or lines running: 4, Hours per shift: 8, Shifts per day: 2, Days in the period: 20, Units one machine makes per running hour: 30, Planned downtime in the period (optional): 40.
2. Apply the method: Capacity = ((Machines × Hours per shift × Shifts per day × Days in period) − Planned downtime) × Units per running hour.
3. Planned downtime is deducted only because it was entered; nothing is assumed.

## Common questions

### Where does this formula come from?

IMA Statements on Management Accounting, measuring the cost of capacity — capacity is the output the resources could produce in the period, and utilisation is the output actually achieved as a share of it. See the source link on this page.

### What kind of calculation is this?

Scheduled machine hours, less the planned downtime entered, multiplied by the demonstrated rate per running hour. 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. This is nominal capacity from the schedule; it is not a forecast of what the line will actually make.

### How do I use the Production Capacity Calculator?

Enter the required values for Machines or lines running, Hours per shift, Shifts per day, Days in the period, Units one machine makes per running hour, 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 Capacity Calculator use?

Capacity = ((Machines × Hours per shift × Shifts per day × Days in period) − Planned downtime) × Units per running hour 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 Capacity 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 capacity calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
