Okay, let’s tackle this. So John has 54 years of experience as a CPA, which is extremely extensive. His skills include accounting, financial reporting, auditing, and tax, which are all in demand. However, his self-employed status means he doesn’t have a traditional employer-employee relationship, which can impact compensation. Location is St. Charles, MO, which is a mid-sized city. According to the Bureau of Labor Statistics, accountants in the St. Louis, MO metropolitan area have median salaries around $80,000. However, considering his extensive experience and certifications, I would estimate his hourly rate to be on the higher end of the spectrum. Let’s consider the American Institute of Certified Public Accountants (AICPA) salary survey, which suggests that CPAs with 20-30 years of experience can earn around $150 per hour. Given John’s 54 years of experience, I would estimate his rate to be closer to $125 per hour, but this is still a rough estimate.
