The profit impact

Scenario vs baseline
Monthly operating profit$17,513

+$2,513 vs $15,000 baseline

Net revenue
$94,763
Baseline $95,000
Operating margin
18.5%
Baseline 15.8%
Break-even units
559
At 950 planned units
Contribution per unit
$44.75
Net price less variable cost
Profit improves under these assumptions.

You need at least 894 units at the scenario economics to match baseline profit, versus 950 planned.

Volume could fall 41.2% from the scenario level before reaching break-even.

FROM ASSUMPTION TO OUTCOME

What drives the change?

+$2,513 total

Each step changes one assumption. Positive values add profit; negative values reduce it.

Sales volume-$2,000
List price+$4,513
Discount$0
Variable cost$0
Fixed costs$0

Bridge order: volume → list price → discount → variable cost → fixed costs. Contributions depend on this order; the total profit change does not. Values shown are rounded.

How the model works and where it stops

Operating profit = units × [list price × (1 − discount / 100) − variable cost per unit] − fixed costs. Operating margin is profit divided by net revenue; it is undefined when revenue is zero.

Break-even units = fixed costs ÷ contribution per unit, rounded up. With positive fixed costs and non-positive contribution, break-even is impossible. When fixed costs are zero, zero units breaks even; selling at negative contribution still creates a loss.

Scope: one product or stable product mix, USD, one month. Unit costs stay constant and fixed costs stay fixed within the relevant capacity range. Demand, capacity constraints, taxes, interest, inventory timing and cash flow are not modeled. These are planning scenarios, not forecasts or verified client outcomes.
