How to Use This Break Even Point Calculator

Five steps to calculate your break‑even point in units and revenue

1
Enter your fixed costs. These are expenses that stay the same regardless of sales volume — rent, salaries, insurance, software subscriptions, and other overhead.
2
Choose your input mode. Use Price + Variable Cost mode to enter the selling price and variable cost per unit, or switch to Margin Ratio mode to enter the contribution margin ratio as a percentage of the selling price.
3
Enter expected unit sales and optional target profit. Set how many units you plan to sell to see your projected profit or loss. Optionally add a target profit to find how many units you need to hit that goal.
4
Review exact and rounded break‑even results. The calculator shows both the exact formula result (which may be fractional) and the minimum whole units you must sell to fully cover all costs.
5
Use the chart to compare revenue, cost, profit, and loss zones. The break‑even chart shows where the revenue line (green) crosses the total cost line (red) — that intersection is your break‑even point.

What is Break Even Analysis?

Understanding the fundamentals of break even point calculation

Break even analysis determines the point at which your total revenue equals your total costs — meaning you neither make a profit nor incur a loss. The break even point (BEP) tells you exactly how many units you need to sell or how much revenue you need to generate to cover all your fixed and variable expenses.

Product Launches

Find the minimum sales volume needed to make a new product profitable before you invest.

Pricing Decisions

Model how price changes affect your break‑even volume and contribution margin.

Profit Planning

Set target profit goals and see exactly how many units you must sell to reach them.

Break Even Formulas

Key formulas used to calculate the break even point

The calculator returns both the exact break‑even point (which may be fractional) and the rounded break‑even point (the minimum whole units needed to cover all costs). In practice, always round up — partial units don't pay bills.

Break Even Point (Units)

BEP = Fixed Costs ÷ (Price − Variable Cost)

Round up fractional results to the next whole unit.

Break Even Point (Revenue)

BEP = Fixed Costs ÷ Contribution Margin Ratio

Multiply rounded units by price for the revenue needed.

Contribution Margin

CM = Price per Unit − Variable Cost per Unit

The amount each sale contributes toward covering fixed costs.

Units for Target Profit

Units = (Fixed Costs + Target Profit) ÷ CM

Extends the BEP formula by adding your desired profit to fixed costs.

Fixed Costs vs. Variable Costs

Understanding the two types of costs in break even analysis

Fixed Costs

Costs that remain constant regardless of how many units you produce or sell.

Rent and lease payments
Salaries of permanent staff
Insurance premiums
Equipment depreciation
Loan payments

Variable Costs

Costs that change proportionally with the number of units produced or sold.

Raw materials
Direct labor (per unit)
Packaging and shipping
Sales commissions
Transaction fees

Break Even Point Example

A practical example of break even analysis for a small business

Candle-Making Business

200 candles/mo

A home candle business has $2,000/month in fixed costs (workshop rent, equipment lease). Each candle costs $4 in wax, wick, and fragrance. They sell for $14 each.

Contribution Margin

$14 − $4 = $10/candle

Break Even Point

$2,000 ÷ $10 = 200 candles

At 200 candles, total revenue ($2,800) exactly covers total costs ($2,000 fixed + $800 variable). Every candle sold beyond 200 generates $10 in pure profit.

How to Read the Break Even Chart

Understanding the visual break even analysis chart

The break even chart plots revenue and total cost against the number of units sold. The break even point is where the revenue line (green) crosses the total cost line (red).

Revenue line

Starts at zero and rises with each unit sold at the selling price. Steeper slope = higher price per unit.

Total cost line

Starts at fixed costs and rises with variable costs per unit. The gap to revenue determines profit or loss.

Fixed cost baseline

A dashed horizontal line showing overhead that stays constant regardless of sales volume.

Break even point marker

The intersection where revenue equals total cost. Left = loss zone, right = profit zone.

Common Break Even Mistakes

Avoid these common errors when performing break even analysis

Forgetting hidden fixed costs

Include marketing budgets, software subscriptions, accounting fees, and other overhead.

Ignoring variable cost changes at scale

Bulk discounts can lower variable costs, but increased demand may raise shipping costs.

Using revenue instead of contribution margin

The BEP formula requires contribution margin (price minus variable cost), not just price.

Not accounting for taxes

Break even analysis typically shows pre-tax break even. Factor in tax obligations for a complete picture.

Assuming a single product

For multiple products, use a weighted average contribution margin based on your expected sales mix.

Treating all costs as either fixed or variable

Some costs are semi-variable (e.g., utilities). Split them into fixed and variable portions for more accurate analysis.

Frequently Asked Questions

Common questions about break even analysis and calculation

To calculate the break even point, divide your total fixed costs by the contribution margin per unit (selling price minus variable cost per unit).

For example, if your fixed costs are $10,000, your selling price is $50 per unit, and your variable cost is $30 per unit, the contribution margin is $20. The break even point = $10,000 ÷ $20 = 500 units. You need to sell 500 units to cover all costs — every unit beyond that generates profit.

The formula is: BEP = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). For the break even point in sales dollars, divide fixed costs by the contribution margin ratio instead. Use this calculator to compute both instantly.

Divide your total fixed costs by the contribution margin per unit (selling price minus variable cost per unit).

For example, if your fixed costs are $10,000, your selling price is $50 per unit, and your variable cost is $30 per unit, the break even point = $10,000 ÷ ($50 − $30) = 500 units. Since you cannot sell a fraction of a unit, always round up fractional results to the next whole unit — the calculator does this automatically.

The formula is: BEP (units) = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit).

There are two key formulas:

Break Even Point in Units: BEP = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit)

Break Even Point in Revenue: BEP = Fixed Costs ÷ Contribution Margin Ratio, where the contribution margin ratio = (Price − Variable Cost) ÷ Price.

Both formulas are built into this calculator. If you use the Margin Ratio input mode, you can enter the contribution margin ratio directly as a percentage instead of computing it from price and variable cost.

To find the break even point in sales dollars (revenue), divide your total fixed costs by the contribution margin ratio.

The contribution margin ratio equals (Price − Variable Cost) ÷ Price. For example, if your price is $50, variable cost is $30, the ratio is ($50 − $30) ÷ $50 = 0.40 or 40%. With $10,000 in fixed costs, BEP in revenue = $10,000 ÷ 0.40 = $25,000.

You can verify this: 500 units × $50 = $25,000 — the same result as the unit-based formula, just expressed in dollars.

Contribution margin is the amount each unit sale contributes toward covering fixed costs and generating profit. It equals the selling price per unit minus the variable cost per unit.

The contribution margin ratio is the contribution margin divided by the selling price, expressed as a percentage. For example, if you sell a product for $50 and it costs $30 to make, the contribution margin is $20 (40% of price). This means every unit sold contributes $20 toward paying your fixed costs, and once those are covered, the full $20 becomes profit.

A higher contribution margin means you break even faster with fewer unit sales.

Fixed costs remain constant regardless of production volume — examples include rent, salaries, insurance, and equipment depreciation. Variable costs change with each unit produced — examples include raw materials, packaging, shipping, and sales commissions.

Understanding this distinction is crucial for break even analysis because the formula depends on separating these two cost types. If you mistakenly classify a variable cost as fixed (or vice versa), your break even calculation will be wrong.

Some costs are semi-variable (e.g., utilities that have a base charge plus usage fees). For accurate analysis, split these into their fixed and variable components.

A break even chart plots revenue and total cost against the number of units sold. The break even point is where the revenue line (green) crosses the total cost line (red).

To the left of this intersection is the loss zone — total costs exceed revenue. To the right is the profit zone — revenue exceeds total costs. The chart also shows the fixed cost baseline as a dashed horizontal line, which is the starting point of the total cost curve.

The steeper the revenue line relative to the cost line, the faster you reach break even. This is why products with high contribution margins require fewer unit sales to become profitable.

Yes, break even analysis works for service businesses too. Fixed costs might include office rent, software subscriptions, and administrative salaries. Variable costs could be labor hours per client, materials used per job, or payment processing fees.

The ‘unit’ can be a service hour, a completed project, a client served, or any other measurable output. Use the unit label field in this calculator to customize it to your business — for example, set it to ‘hours’ for a consulting firm or ‘clients’ for a salon.

For service businesses with different price tiers or service types, calculate break even separately for each tier or use a weighted average based on your expected mix of service types.

If the variable cost per unit is higher than the selling price, the contribution margin is negative, meaning every unit sold increases your losses. In this case, break even cannot be achieved — the calculator will show an invalid state.

You have three options: (1) raise your selling price, (2) reduce variable costs (find cheaper materials, improve efficiency, negotiate supplier discounts), or (3) reconsider whether the product is viable at all.

Some businesses intentionally sell at a loss (loss leader strategy) to acquire customers who will buy higher-margin products later. Break even analysis helps quantify exactly how much you are losing per unit so you can plan accordingly.

Break even analysis shows how many units you need to sell at different price points. Raising the price increases contribution margin and lowers the break even point, but may reduce demand. Lowering the price may increase volume but requires more sales to break even.

Use this calculator to model different scenarios: What if you raise your price from $50 to $60? The contribution margin increases from $20 to $30, and your break even drops from 500 to 334 units — but can you still sell 334 units at the higher price?

The calculator helps you find the optimal balance between price, volume, and profitability. Pair it with the Contribution Margin Calculator and Margin Calculator for deeper pricing analysis.

To calculate units needed for a target profit, use: Units = (Fixed Costs + Target Profit) ÷ Contribution Margin per Unit.

This extends the break even formula by adding your desired profit to the numerator. For example, if fixed costs are $10,000, contribution margin is $20/unit, and you want $5,000 in profit: units = ($10,000 + $5,000) ÷ $20 = 750 units.

The calculator shows both the exact formula result and the rounded whole-unit result. It also shows the revenue you need to generate at that unit count, so you can set both unit-based and revenue-based targets for your team.
