The Book

The Psychology of Math-Based Investing

The Psychology of Math-Based Investing offers a refreshing approach to financial literacy by combining practical investing principles with a deep understanding of human behavior.

Written by therapist Kevin Crabtree, LPC, the book explores how simple mathematical principles, when paired with healthy financial habits and clear thinking, can help ordinary people steadily build long-term wealth.

Unlike many traditional finance books that focus only on numbers, this work also addresses the emotional realities behind money. Financial stress, anxiety, relationship conflict, and fear of the future often shape the financial decisions people make. By understanding these psychological patterns, readers can begin to make calmer, more thoughtful financial choices.

Drawing on more than 25 years of studying how everyday individuals grow their wealth, Kevin explains how consistent habits, disciplined thinking, and basic financial math can gradually transform a person’s financial future.

This book delivers a message of realistic financial hope, showing that wealth is not reserved for investing experts or high-income earners. With patience, understanding, and the right mindset, ordinary people can build extraordinary financial stability.
