Calculate Break Even Point When There's Tax

The break even point is the level of sales at which total revenue equals total costs, including taxes. Calculating this accurately requires accounting for tax impacts on both revenue and expenses.

What is Break Even Point?

The break even point is the sales volume at which a business covers all its costs and starts generating profit. For taxable businesses, this calculation becomes more complex because taxes affect both revenue and expenses differently.

Understanding the break even point helps businesses determine how much revenue they need to generate to cover all costs, including taxes, and start making a profit. This is particularly important for businesses in tax-heavy industries or those with significant tax liabilities.

How to Calculate Break Even with Tax

Calculating the break even point with tax involves several steps. First, you need to determine your fixed and variable costs. Fixed costs are those that do not change with the level of production, such as rent and salaries. Variable costs are those that vary with production, such as materials and labor.

Next, you need to account for taxes. Taxes can affect both revenue and expenses. For example, sales tax is typically added to the price of goods or services, increasing revenue. Income tax, on the other hand, reduces after-tax profit.

To calculate the break even point with tax, you need to adjust your total costs to account for the impact of taxes. This involves subtracting the expected tax liability from your after-tax profit.

Formula

Break Even Point Formula with Tax

The formula to calculate the break even point with tax is:

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

Where:

Fixed Costs are the costs that do not change with the level of production.
Taxable Income is the income before taxes.
Selling Price per Unit is the price at which each unit is sold.
Variable Cost per Unit is the cost of producing each unit.

This formula accounts for the impact of taxes on both revenue and expenses. By including the taxable income in the numerator, you ensure that the break even point calculation reflects the actual after-tax profit.

Example Calculation

Let's consider a business with the following details:

Fixed Costs: $10,000
Variable Cost per Unit: $50
Selling Price per Unit: $100
Tax Rate: 20%

First, calculate the contribution margin per unit:

Contribution Margin per Unit = Selling Price per Unit - Variable Cost per Unit = $100 - $50 = $50

Next, calculate the taxable income. For this example, we'll assume the taxable income is $20,000.

Now, calculate the break even point:

Break Even Point = (Fixed Costs + Taxable Income) / Contribution Margin per Unit = ($10,000 + $20,000) / $50 = $30,000 / $50 = 600 units

This means the business needs to sell 600 units to cover all costs, including taxes, and start generating profit.

FAQ

What is the difference between break even point and contribution margin?: The break even point is the level of sales at which total revenue equals total costs. The contribution margin is the amount of revenue that remains after covering variable costs. The contribution margin is used to calculate the break even point.
How does tax affect the break even point?: Tax affects the break even point by reducing after-tax profit. Taxes on income reduce the amount of profit available for reinvestment or distribution to shareholders. Therefore, businesses need to account for taxes when calculating the break even point.
Can the break even point be negative?: No, the break even point cannot be negative. It represents the point at which total revenue equals total costs. If the break even point is negative, it means the business is operating at a loss and not covering its costs.
How often should I recalculate the break even point?: You should recalculate the break even point whenever there are significant changes in costs, prices, or tax rates. This ensures that the break even point remains accurate and reflects the current business conditions.
What if my business has multiple products?: If your business has multiple products, you need to calculate the contribution margin for each product and then combine them to determine the overall break even point. This involves calculating the weighted average contribution margin and using it in the break even point formula.
