About This Calculator

What it does
Calculates the break-even point — the minimum sales volume and revenue needed to cover all costs. Also computes contribution margin, margin of safety, and required units to reach a target profit.
Inputs required
Total fixed cost, variable cost per unit, selling price per unit. Optional: expected sales volume, target profit amount.
Outputs shown
BEP in units, BEP in revenue, contribution per unit, contribution margin ratio, profit/loss at expected volume, margin of safety, units required for target profit, break-even line chart, profit & loss table.
Formula used
BEP Units = Fixed Cost ÷ (Selling Price − Variable Cost per Unit). BEP Revenue = Fixed Cost ÷ Contribution Margin Ratio. CM Ratio = (Selling Price − Variable Cost) ÷ Selling Price.
Assumptions
Costs are split into fixed and variable only (no step-fixed costs). Selling price and variable cost per unit are constant across all volumes. Fixed costs do not change within the analysis period. No taxes or financing costs included unless added to fixed cost.

How to Use This Calculator

  1. Select your currency. INR is the default. Choose USD, EUR, GBP, or another currency if needed.
  2. Enter total fixed costs. These are your overhead expenses — rent, staff salaries, insurance, software, equipment depreciation — anything that doesn't change whether you sell 0 or 10,000 units this month.
  3. Enter variable cost per unit. This is the direct cost to produce or deliver one unit: raw materials, packaging, shipping, sales commission, or direct labour per item.
  4. Enter selling price per unit. The price must be higher than the variable cost, otherwise every sale makes a loss regardless of volume.
  5. Optional – expected sales volume. Enter your planned or current sales quantity to see whether you're operating at a profit or loss, and by what margin.
  6. Optional – target profit. Enter a profit goal to see exactly how many units and how much revenue you need to hit it.
  7. Click Calculate. Results appear instantly with a break-even chart and a profit/loss table at different volumes.

What Is Break-Even Point?

The break-even point (BEP) is the level of sales at which your total revenue exactly equals your total costs — leaving zero profit and zero loss. Every unit sold beyond the break-even point adds directly to profit; every unit sold below it means you're still covering costs and running at a loss.

Break-even analysis is a fundamental tool for:

  • New businesses deciding whether a product or service is financially viable.
  • Pricing decisions — understanding how a price change affects the volume you need to sell.
  • Investment decisions — evaluating whether a new product, store location, or campaign can pay for itself.
  • Budget planning — setting minimum sales targets for teams.

Break-Even Formula Explained

BEP in units

BEP (units) = Fixed Cost ÷ (Selling Price per Unit − Variable Cost per Unit)

The denominator — Selling Price minus Variable Cost — is called the contribution per unit. It is the amount each sale contributes toward covering your fixed costs and, eventually, generating profit.

BEP in revenue

BEP (revenue) = Fixed Cost ÷ Contribution Margin Ratio
Contribution Margin Ratio = (Selling Price − Variable Cost) ÷ Selling Price

Units required for a target profit

Required Units = (Fixed Cost + Target Profit) ÷ Contribution per Unit

Variable definitions

  • Fixed Cost: Total costs that do not change with production volume (rent, salaries, insurance).
  • Variable Cost per Unit: Cost that changes with each unit produced (materials, packaging, direct labour).
  • Selling Price per Unit: The price at which you sell one unit to a customer.
  • Contribution per Unit: Selling Price − Variable Cost per Unit.
  • Contribution Margin Ratio (CM%): Contribution per Unit ÷ Selling Price, expressed as a percentage.

Worked Example

Suppose you run a small product business with these numbers:

  • Monthly fixed costs: ₹50,000 (rent ₹20,000, salaries ₹25,000, insurance ₹5,000)
  • Variable cost per unit: ₹300 (materials ₹200, packaging ₹60, shipping ₹40)
  • Selling price per unit: ₹500

Step 1 – Contribution per unit: ₹500 − ₹300 = ₹200

Step 2 – BEP in units: ₹50,000 ÷ ₹200 = 250 units

Step 3 – BEP in revenue: 250 × ₹500 = ₹1,25,000

Step 4 – CM Ratio: ₹200 ÷ ₹500 = 40%

Interpretation: You need to sell exactly 250 units this month, earning ₹1,25,000 in revenue, before you make any profit. If you sell 300 units, your profit is (300 − 250) × ₹200 = ₹10,000. Your margin of safety at 300 units is (300 − 250) ÷ 300 = 16.7%.

How to Interpret Your Results

  • Break-Even Units: The minimum number of units you must sell each period to cover all costs. Treat this as your sales floor, not your target.
  • Break-Even Revenue: Useful if you sell multiple products or services — it tells you the total turnover you need, regardless of mix.
  • Contribution Margin (%): A higher CM% means you reach profitability faster. A CM% below 20% typically means a thin-margin business where volume is critical. Above 50% signals strong pricing power.
  • Profit/Loss at Expected Volume: If this is positive, you're comfortably above break-even. If negative, you need to either increase volume, raise price, or cut variable costs.
  • Margin of Safety: A margin of safety under 10% is a warning sign — a small sales shortfall tips you into a loss. Above 25% is generally considered comfortable. Above 50% means a very resilient business model.

Common Mistakes in Break-Even Analysis

  • Mixing up fixed and variable costs. Staff salaries are usually fixed; sales commissions are variable. Misclassifying them gives you a wrong BEP.
  • Using average selling price without accounting for discounts. If 30% of your sales go at a 20% discount, use the weighted average price in your calculation.
  • Ignoring semi-variable costs. Some costs are partly fixed and partly variable — for example, a delivery service with a base fee plus a per-parcel charge. Separate the two components before entering them.
  • Assuming capacity is unlimited. Break-even analysis assumes you can sell as many units as needed. In practice, you may hit production or staffing limits before reaching a very high BEP.
  • Using cost-plus pricing instead of market pricing. Your selling price should reflect what customers will actually pay, not just what makes the numbers work on paper.
  • Not revisiting BEP when costs change. Rent increases, material cost changes, and new hires all affect your BEP. Re-run the analysis whenever your cost structure changes significantly.

Frequently Asked Questions

The break-even point is the number of units you must sell — or the revenue you must earn — so that your total income exactly covers all your costs, leaving neither a profit nor a loss. Sell less than the BEP and you make a loss; sell more and you make a profit.
BEP (units) = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit). The denominator is the contribution per unit — the portion of each sale that goes toward covering fixed costs. Once fixed costs are fully covered, every additional unit sold generates pure profit.
Contribution margin is the selling price minus the variable cost per unit. It tells you how much each unit sale "contributes" toward covering your fixed costs and eventually generating profit. Contribution margin ratio (%) = (Selling Price − Variable Cost) ÷ Selling Price × 100.
Margin of safety is the percentage by which your current or expected sales volume exceeds the break-even point. A margin of safety of 20% means sales can fall 20% before you start making a loss. It is a key measure of business risk — a higher margin of safety means more buffer against downturns.
Break-even analysis lets you test different price points before committing. If you raise your selling price, your contribution per unit increases and BEP units drop, meaning you become profitable sooner. Conversely, price cuts require proportionally higher sales volume to remain profitable. Use the calculator to compare scenarios.
Fixed costs stay the same regardless of how many units you produce or sell — examples include rent, salaries, insurance, and software subscriptions. Variable costs change with production volume — examples include raw materials, packaging, shipping, and sales commissions. Correctly separating these two is the most important step in break-even analysis.
The standard break-even formula does not account for income tax, GST, or other taxes. The break-even point gives you the pre-tax profit threshold. If you want an after-tax target, use the Target Profit field: enter your desired after-tax profit divided by (1 − tax rate) to find the pre-tax equivalent target.
Yes. For services, define a "unit" as a billable hour, a project, a subscription seat, or any repeatable service delivery. Fixed costs are overheads (office, salaries, software). Variable cost per unit is the direct cost of delivering one service unit. The same formula applies.
