What constitutes an Infinite Rate of Return?

An Infinite Rate of Return occurs when an investment results in a profit that exceeds the initial capital investment, effectively making the initial amount zero. This situation can arise in scenariOS such as receiving a cash flow that is not constrained by any initial cost, like when an investor receives a gift or revenue from a business they own outright without any debt or other obligations. In practical terms, it is a theoretical concept since any investment typically involves some cost.
