Example: https://askcalculators.com/ie/break-even/?fixedCost=10000&unitPrice=50&variableCost=30&targetProfit=0

## Inputs
- fixedCost: Fixed costs in one consistent period; type=money; required; default=10000; min=0; max=1000000000000
- unitPrice: Net selling price per unit; type=money; required; default=50; min=0; max=1000000000000
- variableCost: Variable cost per sold unit; type=money; required; default=30; min=0; max=1000000000000
- targetProfit: Target profit in the same period; type=money; required; default=0; min=0; max=1000000000000

## Outputs
- contribution: Contribution per unit; format=currency
- breakEvenUnits: Whole units required to break even; format=number
- targetUnits: Whole units required for target profit; format=number
- targetRevenue: Revenue at rounded target units; format=currency; primary

## Formula
whole target units = ceiling((fixed costs + target profit) ÷ (unit price − variable cost)).

Inputs are converted to canonical units before evaluating this stated formula.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
