Profit Scenario Analysis

Frequently Asked Questions

How do I do scenario planning?

Build best/base/worst case projections. Best case: aggressive growth assumptions, low costs. Base: realistic assumptions. Worst: revenue 30% below plan, costs 20% above. Stress test cash flow under worst case - would you survive 6 months? If not, change strategy.

How probable is the "base case"?

Honestly, base case rarely materializes exactly. Plan for outcomes within ±20% of base case ~60% of the time. Outside that range ~40% of the time. The value is preparation, not prediction - you should know what you'll do in each scenario.

How This Calculator Works

You enter best, expected, and worst-case revenue, an average unit price, the variable cost as a percent of revenue, and annual fixed costs. The tool returns profit and margin for each scenario, the breakeven point in units and dollars, the contribution margin, and a sensitivity table around the expected case at −20% to +20%.

Formula

Contribution margin = 1 − variableCost%. Profit at any revenue = revenue × contributionMargin − fixedCosts. Contribution per unit = price × contributionMargin, so breakeven units = fixedCosts ÷ contributionPerUnit and breakeven revenue = breakeven units × price. Each sensitivity row recomputes profit at expected revenue scaled by (1 + step%).

Common Mistakes

Entering variable costs as dollars instead of a percent of revenue.

Leaving fixed costs out of the figure, which understates breakeven.

Setting best, expected, and worst cases too close together to reveal real risk.

Confusing contribution margin with net margin - the former excludes fixed costs.

Forgetting that high fixed costs amplify both profit and loss swings (operating leverage).

Tips & FAQ

Why model three scenarios? A single forecast hides the floor where you lose money and the ceiling that justifies investment.

What is the margin of safety? Expected revenue minus breakeven revenue - the cushion before you turn unprofitable.

What variable-cost ratio is typical? Roughly 15–25% for SaaS and 60–70% for restaurants.
