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

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.

Interpretation

Break-even billable hours shows the billed delivery needed to recover first-year loaded and one-off hiring cost.

Scenario study: threshold, sensitivity and feasibility

Compare recovery hours with genuinely productive capacity

Loaded first-year cost divided by positive contribution per billable hour gives the recovery threshold. Attendance hours are not automatically productive or billable hours.

Input basis

  • Annual loaded cost: 72,000 CU; one-off hiring cost: 6,000 CU.
  • Contribution per billable hour: 65 CU.
  • Available productive capacity: 95 hours per month for 12 months.
RowIntermediate calculationResult
First-year cost72,000 + 6,00078,000 CU
Break-even billed hours78,000 ÷ 651,200 hours
Available productive capacity95 × 121,140 hours
Capacity gap1,140 − 1,200−60 hours

Interpretation

The entered capacity falls 60 billable hours short of the recovery threshold. Lower contribution or a slower ramp widens that gap.

Boundaries and next step

  • No salary benchmark, utilisation target or hiring recommendation is supplied.
  • Employment classification, tax, labour law and service-quality effects remain outside this calculation.

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.
