Affeldt won some sort of scouting badge for honesty, when he realized the San Francisco Giants were paying $500,000 more than what had been agreed in contract negotiations. As Henry Schulman reported in the San Francisco Chronicle: "Affeldt was set to earn $4 million in 2010 under an existing contract with the Giants when they negotiated a two-year, $10 million extension. When the 2010 amount was rewritten into the new contract, someone made a clerical error and typed $4.5 million instead. The Giants and Affeldt signed it without recognizing the mistake." He would have been within his rights to keep the money, as the amount was on a contract signed by both parties, but explained that he could not accept it as he felt it was not right. He had the contract corrected and returned the extra money.
Affeldt published his autobiography in 2013. In it, he talks of his struggles to become an established major leaguer and of his Christian faith, but also broaches on less usual topics, such as growing up as a military brat, how in moving to San Francisco, CA, he managed to overcome his homophobia, and his involvement in combating human trafficking. It is also unusual in that Affeldt wrote the book without the assistance of a ghostwriter.
