## Formula

Machine hours = quantity ÷ (output × working minutes ÷ 60). Duration = machine hours ÷ number of machines.

- The job efficiency factor (e.g. 50 min/h) is a standard estimating method; you enter the value.
- Output comes from manufacturer data or your records.
- Result feeds the construction cost calculator.
- Machine hours = quantity ÷ (output × working minutes ÷ 60). Duration = machine hours ÷ number of machines.
- Inputs used: Quantity to move or process, Equipment output, Job efficiency (working minutes per hour), Number of machines.

## Inputs

- Quantity to move or process
- Equipment output
- Job efficiency (working minutes per hour)
- Number of machines

## Worked example: 500 m³ with an excavator at 60 m³/h

50 working min/h, one machine.
1. Effective = 60 × 50/60 = 50 m³/h.
2. Hours = 500 ÷ 50 = 10 machine-hours.

## Common questions

### Why working minutes per hour?

Machines rarely work 60 minutes an hour because of positioning, waiting and operator breaks.

### Are mobilization and idle hours included?

No. Add delivery, setup and standby hours separately if they are charged.

### Can several machines share the work?

Yes — duration falls, but total machine hours stay the same if they are equally productive.

### How do I use the Equipment Hours Calculator?

Enter the required values for Quantity to move or process, Equipment output, Job efficiency (working minutes per hour), Number of machines. 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 Equipment Hours Calculator use?

Machine hours = quantity ÷ (output × working minutes ÷ 60). Duration = machine hours ÷ number of machines. 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.

### Can the Equipment Hours 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

- Steady output.
- No mobilization or standby time.
- User-entered output figures.
- Results are estimates for planning and learning. Real designs, installations and bids must be checked by a qualified, licensed professional against the codes that apply where you work.
- The result depends on the values you enter for this equipment hours calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
