Calculating A Break Even Point in Excel

The break even point is the level of sales at which total revenue equals total costs, resulting in zero profit. Calculating this in Excel helps businesses determine when they'll start making money.

What is a Break Even Point?

The break even point is the sales volume at which a business's total revenue equals its total costs. At this point, the company neither makes a profit nor incurs a loss. Understanding this concept is crucial for financial planning and budgeting.

Key factors that affect the break even point include:

Fixed costs (expenses that don't change with production volume)
Variable costs (expenses that vary with production volume)
Selling price per unit

Note: The break even point assumes all costs are covered by sales. In reality, businesses often need to sell beyond the break even point to achieve profitability.

Break Even Formula

The basic break even formula is:

Break Even Point (units) = Fixed Costs / (Selling Price per Unit - Variable Cost per Unit)

Where:

Fixed Costs = Total fixed costs (rent, salaries, etc.)
Selling Price per Unit = Price at which each unit is sold
Variable Cost per Unit = Cost to produce each unit

For monetary break even point (in dollars), use:

Break Even Point (dollars) = Fixed Costs / (1 - (Variable Cost per Unit / Selling Price per Unit))

Calculating in Excel

To calculate the break even point in Excel:

Enter your fixed costs in cell A1
Enter your selling price per unit in cell B1
Enter your variable cost per unit in cell C1
Use the formula in cell D1: =A1/(B1-C1) for unit break even
For monetary break even: =A1/(1-(C1/B1))

You can then create a chart to visualize how sales need to grow to reach break even.

Excel Calculation Example
Fixed Costs	Selling Price	Variable Cost	Break Even (Units)	Break Even ($)
$10,000	$50	$30	=A2/(B2-C2)	=A2/(1-(C2/B2))

Worked Example

Let's calculate the break even point for a company with:

Fixed costs: $10,000
Selling price per unit: $50
Variable cost per unit: $30

Using the unit formula:

Break Even Point = $10,000 / ($50 - $30) = $10,000 / $20 = 500 units

Using the monetary formula:

Break Even Point = $10,000 / (1 - ($30/$50)) = $10,000 / (1 - 0.6) = $10,000 / 0.4 = $25,000

This means the company needs to sell 500 units or $25,000 in revenue to cover all costs.

FAQ

What if my variable cost is higher than my selling price?: If your variable cost per unit is higher than your selling price, you'll never reach a break even point. This means you're losing money on every unit sold.
How do I calculate break even with multiple products?: For multiple products, calculate the break even point for each product separately, then sum the fixed costs and use the weighted average of variable costs and selling prices.
What's the difference between unit and monetary break even?: The unit break even shows how many units you need to sell, while the monetary break even shows the total revenue needed to cover costs. Both are useful depending on your business model.
How often should I recalculate my break even point?: You should review your break even point whenever there are significant changes in costs, prices, or market conditions. At minimum, do this annually.
Can I use this formula for services instead of products?: Yes, the same principles apply. Fixed costs might include office rent and salaries, while variable costs would be materials or time spent on each service.
