> 125k salary ends up being about 250k once all other direct and indirect costs are factored in.
I find an additional $125k to be a stretch, but I also have no data to back this up. I'd be curious to see the breakdown for this: $125k + some share of insurances, office spare per square meter, equipment, training, social events, etc - what else?
That's the standard rule of thumb, that your cost to your employer is roughly double your salary. Of course it depends on tax rates, insurance rates, quality of benefits, etc. But if you are just estimating for a company you don't have much knowledge about there isn't a much better number to use.
social security /FICA taxes from the employer, retirement benefit contributions, other benefits, and basically the entire cost of your HR deptartment and possibly other cost centers.
