This fractions calculator lets you visually divide any whole into parts using an interactive tree structure. It is designed for use cases such as inheritance distribution, investment splits, joint ownership, and more. Users can freely zoom, pan, and move items to build nested fractional structures.

• Click the ellipsis (⋯) on a node to add, delete, or unlock parts.
• Click the fraction (e.g. “1/3”) to edit the share amount.
• Click the node name to rename it.
• Drag and drop nodes to change their nesting and hierarchy.

Whether you're a lawyer, accountant, project manager, or just splitting up a pizza, this tool gives you full control over fractional ownership, contributions, or responsibilities. No login required.
