Term life, in plain English
You pick a length (10, 20, or 30 years) and lock in a flat premium for that whole stretch. If something happens to you during the term, your family gets the full benefit. It's the most protection per dollar by a wide margin, which is why it fits the high-need years: while there's a mortgage to cover, kids to raise, and an income your family runs on.
Whole life, in plain English
Whole life is permanent. It doesn't expire as long as you pay it, the premium never goes up, and part of what you pay builds cash value you can borrow against later. It costs more than term for the same death benefit, because it's designed to be there at ninety-five exactly as it was at thirty-five. It fits lifelong needs: a guaranteed legacy, final expenses, or covering a dependent who will always need support.
How to actually choose
Start with the job you're solving. Protecting your family during the working, mortgage-paying years? Term, almost always. Wanting a guaranteed payout whenever it comes, or building a small permanent foundation? That's where whole life or indexed universal life earns its keep. Plenty of families do both: a large term policy for the big years, plus a modest permanent policy underneath it.
The common mistake is buying expensive permanent coverage when a larger, cheaper term policy would have protected the family better right now. I'll always point you toward what fits, not what pays the most, and if term is all you need, I'll say so.
