Based on the provided skills, Caleb's rate is estimated at $75 per hour. This is a relatively conservative estimate, considering the demand for data analysis and planning professionals in the United States. The average salary for a data analyst in the US is around $60,000 per year, which translates to approximately $29 per hour. However, Caleb's skills in Alteryx, Microsoft Excel, and retirement planning may warrant a higher rate. Considering the industry demand and his location in Cedar Rapids, Iowa, a rate of $75 per hour is a reasonable estimate.
