MK-061 | Break-even revenue calculation
For a regular chat, upload packs/mk-061.md. It includes the shared rules, this method, and required references
Purpose
This skill delivers: A break-even table based on fixed expenses and contribution margin ratio
Recalculability does not mean the data is complete; break-even points and cost ceilings apply only under the stated assumptions
Required inputs
Provide: Fixed costs and contribution rate for the same period, or net revenue and variable costs needed to derive that rate
For method questions, provide the formula, variables and an example directly; for a calculation, ask only for missing operands
Method
- Break-even revenue = fixed costs ÷ contribution margin ratio
- Assuming a contribution margin ratio of approximately 30–40%, the course material offers roughly three times fixed costs as a quick estimate; use the actual contribution margin ratio for a formal calculation
- When the contribution margin ratio is too low, reduce costs/adjust prices first instead of forcing traffic growth at an extremely low contribution ratio
Calculations and interpretation
Break-even revenue = fixed costs ÷ contribution margin ratio
Retain original values, units, periods, and substituted formulas. The formula is not an unconditional guarantee of results
Define gross profit, contribution margin, cost denominators, and periods explicitly; do not copy classroom example numbers as universal thresholds
Required output fields
| Order | Field | How to complete |
|---|---|---|
| 1 | Input variable | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 2 | Value | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 3 | Unit and definition | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 4 | Source | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 5 | Formula | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 6 | Result | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 7 | Limitations | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
Verification cases
MK-061-C05 | A required denominator is zero
Expected: Report that the formula is undefined; do not output a zero cost or an infinite target
MK-061-C06 | Only some costs are supplied
Expected: Retain the partial result and excluded items; do not call it complete profitability
