In general, I would say to take a hard look at level term insurance for a 15 to 20 year term. Level term means a fixed premium for the life of the policy. If you can get a policy that has an option to convert to whole life later then that is a plus in that you have added flexibility. This will cover you until age 45-50. Buy enough now to pay off that mortgage plus a decent amount over that to help the surviving spouse get past the loss of the other's income. If you plan on having kids in the next few years add some more on top of that. Term life insurance is much cheaper than whole or variable life or universal life or whatever they want to call it. Use the money you save on term vs whole/variable life to save aggressively for your retirement. Ten years from now you will need to reevaluate your life/financial situation and probably buy another 15-20 year level term policy for some higher amount to account for changes. The new policy will cover you until age 55-60. At that time, if you have been smart, worked hard and saved aggressively then you will be able to kiss the insurance companies goodbye.
Many people, mostly insurance agents, will disagree with this and say term insurance is a waste of money and you have nothing when the policy period is over. All your premium payments were wasted and you have nothing to show for it. This is true, but are you buying life insurance or investing for the future? Did you invest the savings? If so, be thankful you didn't need the coverage and look at how much in premiums you saved over that 15-20 years. How much are those savings now worth? Your premiums are gone but you were protected at a low cost and had peace of mind in the meantime. Buy insurance from insurance companies and invest for the future elsewhere. Insurance companies are high cost investment options and their results will usually pale in comparison to other options available to you. Best of luck to you.
Well, it's getting expensive for THREE (incl Wobbles) to go!
