Key duplication batch price and blank quantity
Price a supplied duplication order from required usable keys, measured rejection allowance and recorded production cost.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
planned blanks = ceil(required keys/(1-reject share)); cost = blanks × (blank cost + handling minutes × labor/60) + setup; price = cost/(1-margin)
This budgets an already-authorized order with an appropriate blank and process selected separately. No key code, copying method, bypass instruction, key-system design or authorization determination is provided. Rejection allowance gives expected planning yield, not guaranteed usable output. Use your own records for the same scope and period. Example figures are illustrative, not industry benchmarks. Results exclude income taxes and any cost you have not entered. Check the result before pricing work or committing resources.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Usable duplicate keys required (keys): Use the matching measured quantity, time log, schedule or clearly stated estimate. Zero means intentionally none; an unknown amount is not zero.
- Planning share of blanks rejected (%): Enter a percentage from your records or an explicitly chosen scenario. No typical or recommended rate is supplied.
- Purchase cost per blank (selected currency): Use a supplier quote, invoice, payroll record or allocated cost for the exact job or period named here. Include this amount only once.
- Observed handling time per attempted blank (minutes): Use the matching measured quantity, time log, schedule or clearly stated estimate. Zero means intentionally none; an unknown amount is not zero.
- Loaded labor cost per person-hour (selected currency): Use a supplier quote, invoice, payroll record or allocated cost for the exact job or period named here. Include this amount only once.
- Allocated setup and machine expense for order (selected currency): Use a supplier quote, invoice, payroll record or allocated cost for the exact job or period named here. Include this amount only once.
- Target margin on the quoted price (%): Enter a percentage from your records or an explicitly chosen scenario. No typical or recommended rate is supplied.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Modeled quote before sales tax is $72.00 for the illustrative inputs below.
Example inputs
- Usable duplicate keys required: 20 keys
- Planning share of blanks rejected: 5.00 %
- Purchase cost per blank: $1.00
- Observed handling time per attempted blank: 2.00 minutes
- Loaded labor cost per person-hour: $30.00
- Allocated setup and machine expense for order: $10.00
- Target margin on the quoted price: 25.00 %
- Modeled quote before sales tax
- $72.00
- Entered job cost
- $54.00
- Contribution after entered costs
- $18.00
- Planned whole blanks
- 22 blanks
- Modeled price per required usable key
- $3.60
- The example is illustrative. This is not a market quote. Include all relevant costs; omitted costs are not added automatically.
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Price a supplied duplication order from required usable keys, measured rejection allowance and recorded production cost. Inputs come from your own records and stated assumptions; no rates or legal limits are looked up.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
