Life insurance is simple. It's all about price as long as you're buying the right kind (term, level). Figure out what you need, then get as many quotes as you can. You don't need accidental death and disability. Why would your husband/wife need more money if you die from an accident vs. not an accident?
Figure out when you will achieve financial independence, then figure out how much you will need to pay off your mortgage, student loans, put your kids through college and let your spouse live off of until that time.
I'm a fellow. I have a level, term policy for 10 years. When I graduate, that will be 8 years old and I will add a 20 and 30 year policy with each of the three policies being equal amounts, because I will need less as I move closer to financial independence. I will never add another policy after that. That staggered amount should work well for my family. I would prefer to have all of that in place now, but my wife and child would be fine with why is currently in place. If/when I have the mortgage paid off, kids college saved for and am approaching enough to retire, I will start peeling them off.
