Your life insurance should not be expected to put your kids through college. That’s what student loans are for.
It’s nice if it can pay off your mortgage, but if your spouse works, realistically you only have to have your life insurance cover “your share” of the mortgage and bills. But if you’re gone and your kids are moving out of the house soon, your spouse may not want to stay in that house forever. A lot of folks eventually downsize when they become empty nesters.
Life insurance is like gambling at a casino tilted heavily in the house’s favor. They’ll always make sure the math for your odds of death vs the premiums you pay are in their favor, and then collect administrative fees on top of that.
Funeral expenses and 1-2 years of income is probably “enough” life insurance.
