if there would be a financial hardship if the non-working spouse died.
Let's say the wife has a very
demanding and high income career. The husband stays home to raise the kids and
take care of the house. What if the husband were to suddenly die?
Now
the wife has to hire a nanny, a house keeper, a cook, and possibly a personal assistant
to replace all of the the work that was being done before by the stay-at-home dad.
You would need full-time help or at least part-time help, hiring someone to perform all of the daily tasks the dad was doing; such as, taking the kids to activities, shopping for groceries, cleaning the house, cooking, etc.
Here's how to calculate your life insurance needs for you and your spouse.
