Outputs

Warning

Primary outputs

Base case profit$5,343.00

Profit under the central operating assumption.

Conservative case profit-$15,520.00

Profit under the downside case.

Supporting outputs

Aggressive case profit$53,475.00

Profit under the upside case.

Break-even revenue$100,000.00

Revenue required to cover fixed and variable cost assumptions.

Margin of safety15.1%

Distance between modeled revenue and break-even revenue.

Downside risk$20,863.00

Profit reduction from base case to conservative case.

Upside potential$48,132.00

Profit increase from base case to aggressive case.

Recommended next move

Warning

Conservative case falls below break-even

The base plan is profitable, but a downside move makes it unprofitable. Build a buffer before committing fixed spend.

Assumptions are fragile

A small adverse move can erase the profit buffer. Tighten the most sensitive assumption before treating the plan as durable.

Gross margin is the highest-leverage assumption

Gross margin movement creates the largest downside impact. Protect delivery efficiency, pricing discipline, and mix quality.

Operator context

Use this when

  • Use before committing budget, headcount, or operational capacity.
  • Use when one forecast has too much false precision.
  • Use to expose downside, base, and upside economics.

Interpretation rules

Fragile base caseWarning

If the conservative case is near break-even or negative, delay fixed commitments or add contingency.

Wide scenario bandNeutral

A wide gap between downside and upside means the decision depends on assumption quality.

Operator notes

  • Treat the most sensitive assumption as the first validation target.
  • Prefer scenarios tied to controllable drivers: price, volume, cost, and acquisition spend.

Watch for

  • Changing many assumptions at once can hide the real driver.
  • Using arbitrary downside percentages can create false confidence.
