Standard Cost Calculator
Build a standard cost card from your own standards, never a benchmark.
In short
Build a standard cost card from your own standards, never a benchmark.
Formula: Standard cost = (Standard quantity × Standard price) + (Standard hours × Standard rate) + (Standard hours × Standard overhead rate)
What this calculator does
Each standard element priced separately and added. A standard is the organisation's own expectation; it is not a benchmark and not a target, and none is supplied.
Use it to turn Currency, Standard material quantity per unit, Standard material price, Standard labour hours per unit, 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..
- Standard material quantity per unit
- — number value.
- Standard material price
- — Your own standard price, not a market or benchmark price..
- Standard labour hours per unit
- — number value.
- Standard labour rate per hour
- — number value.
- Standard overhead rate per labour hour (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Units planned (optional)
- — Optional component. Leave at 0 to exclude it from the result. Used to show the total standard cost..
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
Standard cost = (Standard quantity × Standard price) + (Standard hours × Standard rate) + (Standard hours × Standard overhead rate).
Inputs used: Currency, Standard material quantity per unit, Standard material price, Standard labour hours per unit, Standard labour rate per hour, Standard overhead rate per labour hour (optional), Units planned (optional).
Edge handling: Standard material quantity per unit is required.; Standard material quantity per unit cannot be negative.; Standard material quantity per unit must be no more than 1000000000000.; Standard material price is required.; Standard material price cannot be negative..
Worked example
A standard cost card for one unit
- Start with Currency: USD, Standard material quantity per unit: 2.5, Standard material price: 3.20, Standard labour hours per unit: 0.75, Standard labour rate per hour: 28.50, Standard overhead rate per labour hour (optional): 0.
- Apply the method: Standard cost = (Standard quantity × Standard price) + (Standard hours × Standard rate) + (Standard hours × Standard overhead rate).
- Your own standards for quantity, price, hours and rate — never an industry benchmark or a target.
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 standard cost 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) — a standard cost is the expected quantity at the expected price; price and quantity (or rate and efficiency) variances separate the two causes of a difference from standard. See the source link on this page.
What kind of calculation is this?
The expected cost of one unit at the organisation's own standard quantities, prices, hours and rates. 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. A standard cost is an expectation; the actual cost calculator and variance analysis show what really happened.
How do I use the Standard Cost Calculator?
Enter the required values for Currency, Standard material quantity per unit, Standard material price, Standard labour hours per unit, Standard labour rate per 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 Standard Cost Calculator use?
Standard cost = (Standard quantity × Standard price) + (Standard hours × Standard rate) + (Standard hours × Standard overhead rate) 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 Standard Cost 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
The expected cost of one unit at the organisation's own standard quantities, prices, hours and rates.
The question it answers: We came in over cost — was it price, usage, wage rates or time?
The formula
Standard cost = (Standard quantity × Standard price) + (Standard hours × Standard rate) + (Standard hours × Standard overhead rate)
- Sq — Standard quantity per unit
- (material unit). The organisation's own standard.
- Sp — Standard material price
- (currency). The organisation's own standard price, not a market price.
- Sh — Standard hours per unit
- (hour). The organisation's own standard.
- Sr — Standard labour rate
- (currency). The organisation's own standard rate.
- So — Standard overhead rate
- (currency). Optional. Applied per standard labour hour.
- u — Units planned
- (count). Optional. Used to show the total standard cost.
Units: Currency; material units; hours; counts.
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
Each standard element priced separately and added. A standard is the organisation's own expectation; it is not a benchmark and not a target, and none is supplied.
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.
- No standard quantity, price, rate or overhead rate is supplied; all are the user's own.
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.
- A standard cost is an expectation; the actual cost calculator and variance analysis show what really happened.
