Life insurance can help your partner or children continue to pay for any financial commitments you have that might then fall to them to pay if you were no longer here. Life insurance can help to make sure your dependants would then be able to keep up with any mortgage repayments and bills you pay if you passed away. The lump sum payout they would receive could also help to pay for other things you would usually help to cover, like food bills and schooling.
What factors affect life insurance costs:
Your health
Your age
Whether you smoke
Where you live
Amount of cover
Duration of policy
