Example: https://askcalculators.com/calculator/roi-calculator/?invested=5000&finalValue=7500

## Inputs
- invested: Amount invested; type=money; required; default=5000; min=0.01
- finalValue: Final value; type=money; required; default=7500; min=0
- income: Income received; type=money; optional; min=0
- costs: Extra costs; type=money; optional; min=0
- years: Holding period in years; type=number; optional; min=0.01; max=100

## Outputs
- roi: Return on investment; format=percent; primary
- profit: Net profit; format=currency
- multiple: Return multiple; format=number
- annualized: Annualized return; format=percent

## Formula
ROI = (Ending value + income − investment − costs) ÷ (investment + costs) × 100

Annualized return uses geometric growth and needs a holding period.

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