Your entire job compensation consists of not only your salary, but benefits and bonuses as well. Make sure you're comparing apples to apples when comparing job offers or thinking of leaving your company by closely evaluating the benefits.
The new company might offer the same per cent retirement matching just like your current company, for example, they might offer discounts on household products that you may find valuable. Some companies offer travel incentives. Does the new job offer flexible working arrangements? What's the kind of bonus you're likely to get at the end of the financial year at the new company?
Take a closer look at the benefits package — perhaps ask the company for the HR handbook — before accepting a job so you can make sure you're truly moving up to a more rewarding position.
