Bid / No-bid Economics Planner methodology

contributionIfWonExTax = contract price − delivery cost − capacity opportunity cost

expectedBidValueExTax = win probability × contribution if won − bid preparation cost

breakEvenWinProbability = bid preparation cost ÷ contribution if won when contribution is positive

Money inputs and outputs use the currency selected in the scenario without changing the canonical methodology. Rates, margins, utilisation and buffers are entered as percentages and converted to decimal values for calculation.

• All values must be finite and remain inside the visible input boundaries.
• All money values use one consistent ex-tax basis and period.
• Rates must remain inside their engine-owned boundaries.
• Break-even win probability is unavailable when contribution if won is not positive.
• The economic threshold clears only when raw expected bid value is zero or positive.

Contract price minimum

contractPriceExTax ≥ 0 currency units/won bid, ex tax — A lower value is rejected before calculation.

Contract price maximum

contractPriceExTax ≤ 10,000,000 currency units/won bid, ex tax — A higher value is rejected before calculation.

Delivery cost minimum

deliveryCostExTax ≥ 0 currency units/won bid, ex tax — A lower value is rejected before calculation.

Delivery cost maximum

deliveryCostExTax ≤ 10,000,000 currency units/won bid, ex tax — A higher value is rejected before calculation.

Bid preparation cost minimum

bidPreparationCostExTax ≥ 0 currency units/bid submission, ex tax — A lower value is rejected before calculation.

Bid preparation cost maximum

bidPreparationCostExTax ≤ 10,000,000 currency units/bid submission, ex tax — A higher value is rejected before calculation.

Capacity opportunity cost minimum

capacityOpportunityCostExTax ≥ 0 currency units/bid opportunity, ex tax — A lower value is rejected before calculation.

Capacity opportunity cost maximum

capacityOpportunityCostExTax ≤ 10,000,000 currency units/bid opportunity, ex tax — A higher value is rejected before calculation.

Win probability minimum

winProbability ≥ 0 decimal probability of the submitted bid winning — A lower value is rejected before calculation.

Win probability maximum

winProbability ≤ 1 decimal probability of the submitted bid winning — A higher value is rejected before calculation.

• All hours, utilisation, costs, rates and recovery targets are supplied by the user.
• Money values use one consistent ex-tax basis.
• No provider fee, jurisdiction, benchmark or demand forecast is embedded.
• Raw engine precision is retained until display.

This planner has no current policy-data dependency. Its commercial assumptions are user supplied. Registered family-level regression suites exercise the shared business-logic engine and worked-result reconciliation.

• Results depend on the completeness and classification of the entered business records.
• The planner does not forecast demand, utilisation, supplier terms or project outcomes.
• This is educational business decision support rather than accounting, tax, legal or financial advice.
• Win probability and capacity opportunity cost are user scenarios rather than market forecasts.
• The result does not assess tender terms, legal obligations, strategic value or delivery risk outside the entered costs.

This is educational decision support, not tax, accounting, legal or financial advice. Check the treatment of your actual transactions under the rules that apply to your business and seek qualified advice where appropriate.

Registered family-level suites test formula invariants and example reconciliation; the release ledger records that coverage without claiming a separate oracle for every line of public copy. There is no official threshold or benchmark to refresh for this planner. Commercial inputs remain user-supplied because they vary by business and contract.
