It would be great if an HR director could weigh in on how much a $125K salary might cost in total compensation with a "standard benefit package" range for a technologist/programmer/engineer role.

The only other data point is from the Bureau of Labor Statistics Employer Costs for Employee Compensation (BLS ECEC) where it shows at the bottom that benefits accounted for around 30% of total compensation and 70% going to wages & salary[1]. On average, this means that a $125K salary would cost a company $179K overall.
