Term Life Insurance at 41

I’m a 100% disabled veteran and I’m 41. I work and my wife is a stay at home mom raising our 2 year old.

I have a $100,000 policy from my job but if I get fired or move I lose it. I also have one that I got when I got out of the military at 24 when I was working at Home Depot that gives $200,00 when I die. I have a better job as a teacher and I’m looking to bump that a lot higher, according to Ramsey it should be about 1 million based on my salary times a certain amount of years.

I would like a term life insurance policy. Will this thing probably be costly due to my age?
