How this calculation works

agreement revenue-scheduled costs-expected incident cost.

Each incident row is an expected cost component; do not overlap the same loss across rows. Probabilities are assumptions. Scheduled costs exclude those incident losses.

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
  • Annual agreement revenue (selected currency): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for annual agreement revenue. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
  • Annual scheduled visit labor travel and other costs: One row per distinct annual scheduled visit labor travel and other costs, on the stated row and period basis. Do not enter both components and their total.
    • Cost amount (selected currency): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for cost amount. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
  • Assumed annual incident scenarios: One row per distinct assumed annual incident scenarios, on the stated row and period basis. Do not enter both components and their total.
    • Probability of scenario (%): Owner’s explicit comparable-period probability assumption; observed history can inform but not certify it.
    • Annual cost if this scenario occurs (selected currency): Loss if this annual scenario occurs; avoid overlapping the same loss in multiple rows.

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: Expected annual contribution is $600.00 for the illustrative inputs below.

Example inputs
  • Annual agreement revenue: $1,500.00
  • Annual scheduled visit labor travel and other costs
      • Cost amount: $600.00
      • Cost amount: $100.00
  • Assumed annual incident scenarios
      • Probability of scenario: 20.00 %
      • Annual cost if this scenario occurs: $1,000.00

Use the result well

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.
