Proposal Option Profitability Planner methodology

goodContributionPerWin = good price − good cost

betterContributionPerWin = better price − better cost

bestContributionPerWin = best price − best cost

goodExpectedContribution = good contribution × expected wins

betterExpectedContribution = better contribution × expected wins

bestExpectedContribution = best contribution × expected wins

betterVsGoodContribution = better expected − good expected contribution

bestVsBetterContribution = best expected − better expected contribution

bestWinsToMatchGood = good expected contribution ÷ best contribution per win

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.

• Inputs must be finite and remain within the visible boundaries.
• Rates are decimal values and all monetary inputs use one consistent currency and period.
• Whole operational capacity is rounded only where the engine explicitly applies floor or ceiling.

Good option price minimum

goodOptionPrice ≥ 0 currency units/win — A lower value is rejected before calculation.

Good option price maximum

goodOptionPrice ≤ 10,000,000 currency units/win — A higher value is rejected before calculation.

Good option cost minimum

goodOptionCost ≥ 0 currency units/win — A lower value is rejected before calculation.

Good option cost maximum

goodOptionCost ≤ 10,000,000 currency units/win — A higher value is rejected before calculation.

Good expected wins minimum

goodOptionExpectedWins ≥ 0 wins/period — A lower value is rejected before calculation.

• All costs, prices, hours, probabilities and volumes are user-supplied; no market benchmark is inferred.
• Tax is outside these neutral commercial comparisons.
• The engine retains full precision; formatting never feeds back into calculation.

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.

• The model does not predict demand, delivery performance, contract enforceability or customer behaviour.
• It does not replace accounting, tax, legal or financial advice.

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.
