Feng shui practitioners believe that the arrangement of a room influences well-being and productivity. This calculator uses a simplified flow equation to help you experiment with different layouts. Rate the amount of natural light, measure how much open floor space you have relative to the total area, and score the clutter or obstacle level. A higher light value and more open space generally increase flow, while a higher clutter level reduces it.

The formula for flow is expressed as:

where $L$ is the natural light score, $S$ is the open space percentage divided by 100, and $C$ is the clutter level. The constant 1 prevents division by zero when the room is spotless. Rooms with a higher flow score are thought to feel more balanced and relaxing.

Experiment by moving furniture or reducing clutter to see how the score changes. While this tool offers a playful take on feng shui, it can spark ideas for decluttering and making the most of sunlight in any space. Add plants, mirrors, and soft textures to further enhance comfort.
