There’s no such thing as the ‘right’ age to get life insurance. The answer really is that you should take out life insurance when it feels right for you. Typically this tends to be because you’ve moved house, got married, have a new job or have had a baby. It may also be after taking into account your financial position and the financial obligations that may fall to others when you’re not around.
So, for example, for some people having an outstanding mortgage together might drive the decision. Having young children and expensive future education costs might be another.
It’s also worth considering that life insurance is typically cheaper when you’re young and healthy than when you’re older and more likely to be less healthy.
