Changing term life insurance to whole life insurance are there age restrictions?

No, but the older you are, the higher the premiums. You may want to look at the life insurance policy terms and conditions section that refers to "Conversion" or Convertibility Option". This section of your policy should explain how you may convert your term life insurance policy to permanent life insurance, and by what date you may convert. There may be a specific date in the policy by which time you may convert the term life insurance policy to permanent life insurance. Also many companies will offer a "term conversion credit" if converted with a certain number of years, this credit is generally the last 12 months of premium paid on your existing term policy

I would suggest that you check out the convertability terms and conditions specified in your present policy. You may want to check with your insurance agent about this. There are many contingencies which may allow you conversion credit if you convert within a specified number of years.
