Math is good. Philosophy is better. Your salary is what you live on. Everything else is a bonus. As a salaried engineer I have received basically every 'extra' there is. Cash bonus. Equity bonus. Options. Restricted Stock Units. Overtime pay by the hour (seriously!) In all cases I do not plan to get that money. I don't use it to pay rent or a mortgage. I don't use it to buy clothes or food. You might argue that is a luxury, but honestly if you can't afford your lifestyle without the bonus, then what happens when there are bad times and you don't get the bonus? I set this up so explicitly that I have a separate bank account for that money and when a bonus comes in it gets transferred away from the day to day account. This years vacation is paid for with last years bonus.
