# Break-Even Calculator

- **URL:** https://codeasystem.com/calculators/business/break-even-calculator/
- **Category:** business
- **Description:** Find how many units you must sell; and how much revenue that takes; before your business covers its fixed costs.
- **Primary output:** Break-even point: 1,500 units

## Inputs
- Fixed costs (name: `fixed`, type: number, prefix: $, example: 30000)
- Price per unit (name: `price`, type: number, prefix: $, example: 50)
- Variable cost per unit (name: `variable`, type: number, prefix: $, example: 30)

## Outputs
- Break-even point: 1,500 units
- Break-even revenue: $75,000.00
- Contribution margin per unit: $20.00
- Contribution margin ratio: 40%

## Formula / methodology
```
Break-even units = Fixed costs / (Price − Variable cost)
Break-even revenue = Break-even units × Price
```

Every unit sold first pays for its own variable cost; what remains; the contribution margin; chips away at fixed costs. The break-even point is the number of units whose combined contribution margins exactly equal your fixed costs. Beyond it, each sale adds the full contribution margin to profit.

## Assumptions & limitations
- Fixed costs stay constant over the period analyzed.
- Selling price and variable cost per unit do not change with volume.
- Everything produced is sold; no inventory build-up.
- Single-product or constant-mix analysis.

## How to use
1. **Add up fixed costs**; Total the expenses you pay regardless of sales volume for one period; usually a month.
2. **Enter price and variable cost**; Use realistic figures including discounts; variable cost includes everything triggered by a single sale.
3. **Read the break-even point**; The result shows the unit count and revenue needed before profit begins.

## Example
With $30,000 of monthly fixed costs, a $50 price and a $30 variable cost, every sale contributes $20; so you break even at exactly 1,500 units, or $75,000 of revenue.

Result for these inputs:

```
Break-even point: 1,500 units
```

## About this calculator
### Why contribution margin drives everything

Two businesses with identical fixed costs can have wildly different break-even points purely because of their cost structure. A high-margin software product might break even at dozens of customers while a low-margin reseller needs thousands of transactions. Lowering variable cost; renegotiating suppliers, cutting payment fees; moves the point more than most people expect.

### Using break-even for pricing decisions

The calculator makes trade-offs explicit: raising price shrinks the required unit count but may cost you volume, while discounting feels like growth but silently raises the bar you must clear. Before any promotion, re-run the numbers with the discounted price to see how many extra units the deal must bring just to keep pace.

- Contribution margin = price − variable cost per unit.
- Lower fixed costs lower the break-even point linearly.
- If price ≤ variable cost, no volume can ever reach break-even.

## FAQs
### What counts as a fixed cost?

Anything you pay regardless of output: rent, salaried staff, insurance, software subscriptions, loan payments. Owner salary is usually included for a true picture of viability.

### Can I use this for services?

Yes; treat each engagement as a “unit”. Variable cost is whatever delivering one engagement costs you (contractors, usage fees), and price is your fee.

### What if my price equals my variable cost?

Then contribution margin is zero and break-even is mathematically impossible; the calculator explains this instead of returning an infinite number.

### Does the result include profit?

No; it shows exactly where profit starts. Add your target profit to fixed costs and re-run to find the units needed to earn it.
