The Mathematical Foundations of the Potential Payback Period (PPP)
This paper presents the mathematical foundations of the Potential Payback Period (PPP) as a unified framework for asset valuation and return determination. The PPP integrates earnings growth, discounting, and risk into a single dynamic metric derived from exponential growth and present value theory.
