## Formula

Machine hour rate = Total machine cost for the period ÷ Machine hours in the period

- Machine hour rate = Total machine cost for the period ÷ Machine hours in the period.
- Inputs used: Currency, Depreciation for the period (optional), Power and fuel (optional), Maintenance and spares (optional), Tooling and consumables (optional), Floor space and insurance (optional), Other machine cost (optional), Machine hours in the period.
- Edge handling: Depreciation for the period (optional) is required.; Depreciation for the period (optional) cannot be negative.; Depreciation for the period (optional) must be no more than 1000000000000.; Power and fuel (optional) is required.; Power and fuel (optional) cannot be negative..

## Inputs

- Currency
- Depreciation for the period (optional)
- Power and fuel (optional)
- Maintenance and spares (optional)
- Tooling and consumables (optional)
- Floor space and insurance (optional)
- Other machine cost (optional)
- Machine hours in the period

## Worked example: A machine costing its own share of the factory

Everything the machine costs for the period, divided by the hours it runs.
1. Start with Currency: USD, Depreciation for the period (optional): 24000, Power and fuel (optional): 8600, Maintenance and spares (optional): 5400, Tooling and consumables (optional): 3200, Floor space and insurance (optional): 4800.
2. Apply the method: Machine hour rate = Total machine cost for the period ÷ Machine hours in the period.
3. Everything the machine costs for the period, divided by the hours it runs.

## Common questions

### Where does this formula come from?

Principles of Accounting, Volume 2: Managerial Accounting (OpenStax) — job cost is direct materials plus direct labour plus overhead applied at a predetermined rate; unit cost is total production cost divided by the units produced. See the source link on this page.

### What kind of calculation is this?

Everything the machine costs for a period divided by the hours it actually runs. 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 costs, standards or allowances behind them are right. A target cost, an industry benchmark and the organisation's own standard are different things; only the figures entered are used. Running hours, not available hours: idle time raises the rate, which is the intended behaviour.

### How do I use the Machine Hour Rate Calculator?

Enter the required values for Currency, Depreciation for the period (optional), Power and fuel (optional), Maintenance and spares (optional), Tooling and consumables (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 Machine Hour Rate Calculator use?

Machine hour rate = Total machine cost for the period ÷ Machine hours in the period 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 Machine Hour Rate 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 machine hour rate calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
