Insights & recommendations
Break-even risk and what to change to hit £3,000 profit per month.
Break-even risk
Low

Sales could fall 33% before you hit losses — a comfortable cushion.

Break-even is 167 units of your 250 expected — contribution margin 60.0%.

Sell more units
267 units / mo

17 more than today at the same price.

Raise your price
£52.00

+4.0% vs today's £50.00 at 250 units.

Cut variable cost
£18.00

-10.0% vs today's £20.00 per unit.

Trim fixed costs
£4,500

Max monthly overhead that still leaves £3,000 profit (now £5,000).

Each recommendation changes one lever at a time, holding the others at your current inputs. Combining a smaller price rise with a modest cost cut usually beats one big move.

How this calculator works

Break-even units = Fixed costs ÷ (Price per unit − Variable cost per unit). This is the number of sales needed each month before you make a profit.

Margin of safety shows how much sales can drop before you hit losses. Contribution margin tells you what percentage of each sale is available to cover fixed costs.
