That is a very tricky question. The answer is not the same for everyone. It really Depends upon what kind of life style you want. It is said that you will need about 40 times the amount you will need per year. For example if you need 40,000 per year to live on you should have in your Retirement funds around 1,600,000. Two things to remember it will probably take around 600,000 just for your medical needs. That doesn't include your Long Term Care needs. The cost for this really depends upon where you live and the kind a care you need. Your assets should be in several different "buckets" like grand dad always said don't put all your chickens in one basket.
