Machine Hour Rate Calculator
Work out what one hour on a machine costs to run.
In short
Work out what one hour on a machine costs to run.
Formula: Machine hour rate = Total machine cost for the period ÷ Machine hours in the period
What this calculator does
Machine-related costs pooled and divided by running hours, with running and ownership costs shown separately.
Use it to turn Currency, Depreciation for the period (optional), Power and fuel (optional), Maintenance and spares (optional), and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Depreciation for the period (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Power and fuel (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Maintenance and spares (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Tooling and consumables (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Floor space and insurance (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Other machine cost (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Machine hours in the period
- — The hours the machine actually runs, not the hours it is available..
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
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..
Worked example
A machine costing its own share of the factory
- 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.
- Apply the method: Machine hour rate = Total machine cost for the period ÷ Machine hours in the period.
- Everything the machine costs for the period, divided by the hours it runs.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
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.

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.
Formula, source and verification
Everything the machine costs for a period divided by the hours it actually runs.
The question it answers: What does the material, the labour, the overhead and an hour on the machine cost us?
The formula
Machine hour rate = Total machine cost for the period ÷ Machine hours in the period
- D — Depreciation
- (currency). Optional component.
- P — Power and fuel
- (currency). Optional component.
- M — Maintenance and spares
- (currency). Optional component.
- C — Tooling and consumables
- (currency). Optional component.
- S — Floor space and insurance
- (currency). Optional component.
- O — Other machine cost
- (currency). Optional component.
- h — Machine hours
- (hour). Hours the machine runs in the period.
Units: Currency; hours.
What kind of calculation this is
Deterministic formula. The same inputs always give the same answer. The maths is fixed and does not depend on judgement.
Method
Machine-related costs pooled and divided by running hours, with running and ownership costs shown separately.
Assumptions built into the result
- Industry: Every cost, rate and standard is the figure the user entered, in the currency they chose; no exchange rate is applied.
- Mathematical: Costs and output cover the same period or the same job.
Figures this calculator will never guess for you
- No industry average, benchmark or target cost is supplied.
- No standard rate, wage or material price is assumed on the user's behalf.
- Optional components are excluded from the result when left at zero.
Limitations
- 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.
