How to use Black Polish Labor Budget Calculator and understand its results

  1. Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
  2. Enter contingencyPercent, laborRatePerHour, partCount, quotedHoursPerPart, setupHours using the field table and calculation rules, then run the tool.
  3. Read baseHours, budgetedHours, budgetedLaborCost. The explanation below defines the units, signs, ordering and any flags or placeholder values.
  4. If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
Input fieldMeaningValue type; see rules belowRequirement

Enter positive safe integer parts and nonnegative time, hourly rate and contingency. Return base/budgeted hours and budgeted labor cost.

baseHours=parts×hoursPerPart+setup; budgetHours=baseHours(1+contingency/100)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Limitations and assumptions

No finish quality, actual labor time or supplier quote is estimated.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Anglage Labor Budget Calculator: Calculate an anglage labor budget from maker- or supplier-quoted hours; it does not invent a universal hours-per-part estimate. For a complementary task, use Guilloché Dial Artisan Process Lookup: Return a commission, blank-preparation, machine-setup, finishing, or quality-evidence control for a hand- or machine-guided guilloché dial.
