Educational only: Business decision support, not accounting, tax or legal advice.

Privacy: Calculations run locally; Margin101 does not receive your commercial inputs.

Update policy: Reviewed when formulas or official dependencies change.

Scope: Market-neutral small-business planning using your own assumptions.

1. Formulas and units

Contribution Per Unit Ex Tax
contributionPerUnitExTax = unit price − unit variable cost

Where

unitPriceExTax
Unit price (currency units/unit, ex tax)Source: Business record
unitVariableCostExTax
Unit variable cost (currency units/unit, ex tax)Source: Business record
contributionPerUnitExTax
Contribution Per Unit Ex Tax (currency units, ex tax)Source: Calculated output
Recovery Target Ex Tax
recoveryTargetExTax = launch cost + period fixed costs + target profit

Where

launchCostExTax
Launch cost (currency units/planning period, ex tax)Source: Business record
periodFixedCostsExTax
Period fixed costs (currency units/planning period, ex tax)Source: Business record
targetProfitExTax
Target profit (currency units/planning period, ex tax)Source: User assumption
recoveryTargetExTax
Recovery Target Ex Tax (currency units, ex tax)Source: Calculated output
Launch Break Even Units
launchBreakEvenUnits = ceil(recovery target / contribution per unit)

Where

contributionPerUnitExTax
Contribution Per Unit Ex Tax (currency units, ex tax)Source: Calculated output
recoveryTargetExTax
Recovery Target Ex Tax (currency units, ex tax)Source: Calculated output
launchBreakEvenUnits
Launch Break Even Units (whole units)Source: Calculated output
Launch Break Even Revenue Ex Tax
launchBreakEvenRevenueExTax = launch units × unit price

Where

unitPriceExTax
Unit price (currency units/unit, ex tax)Source: Business record
launchBreakEvenUnits
Launch Break Even Units (whole units)Source: Calculated output
launchBreakEvenRevenueExTax
Launch Break Even Revenue Ex Tax (currency units, ex tax)Source: Calculated output
Launch Recovery Months
launchRecoveryMonths = launch break-even units / expected monthly units

Where

expectedMonthlyUnits
Expected monthly units (units/month)Source: User assumption
launchBreakEvenUnits
Launch Break Even Units (whole units)Source: Calculated output
launchRecoveryMonths
Launch Recovery Months (months)Source: Calculated output

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.

Calculation and outputs

Example

The worked rows below come directly from the registered engine and visible default fixture.

Contribution Per Unit Ex Tax
65 currency units
Recovery Target Ex Tax
80,000 currency units
Launch Break Even Units
1,231 units
Launch Break Even Revenue Ex Tax
147,720 currency units
Launch Recovery Months
6.2 months

The exact engine-derived outputs are shown in the labelled rows below.

Interpretation

Launch break-even units covers launch cost, period fixed cost and the entered target profit at the planned unit contribution.

3. Validation and boundary checks

  • All inputs must be finite and within the visible boundaries.
  • Costs, revenue and contribution use one consistent ex-tax basis and planning period.
  • Whole-unit thresholds round upward only where the named engine formula requires it.

4. Assumptions and source classification

  • All prices, costs, demand limits and capacity values are user-supplied records or explicit scenarios.
  • Allocated costs remain visible and separate from avoidable costs.
  • The global workflow infers no market benchmark, policy threshold or future demand.

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.

5. Limitations

  • The model does not forecast demand, implementation timing, service quality or strategic fit.
  • 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.

6. Update and evidence policy

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.
