First of all, the difference between 2 and 5 years is gigantic! Second of all, there again is no quantifiable evidence to prove the efficacy of that statement. It completely depends on the person, the desirability of the good or service, the competitiveness of the industry, the marketing and manufacturing, and much more. To simply say that across all industries you should expect to break* even in 2 to 5 years is complete unfounded garbage.
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
