4% is a guideline
it has known inefficiencies which an individual can plan around (either take advantage of, or save less for example). If 4% appears to save too much, the next best plan I have seen is the 5%-95% model (withdraw 5%, but in down years always leave at least 95% of account balance intact).
4% has inefficiencies because it worked through the 1970's, and if such a decade (flat real returns) does not happen in your retirement, or you die young, you significantly over saved.
5% still has the same inefficiencies, but they appear less.
7% would have same inefficiencies, but they appear less.
Any percentage has the same ineffciencies- and that is it is impossible to know the correct withdraw rate if you do not know when you die. Either something is left, or you live on social security after you run out of assets.
The opposite of that inefficiency is an annuity. The pro is you will never run out of money, the cons are multiple- the top 2 which come to mind are
1) inflation adjustments- the 7% rate for an immediate annuity probably does not have an inflation component built in (the 4% rule DOES have an inflation component built in)
2) Annuities are not transferable on death unless the rate is decreased (so again the 7% rate for an immediate annuity would probably NOT have the ability to transfer income to a spouse, the 4% withdraw rate lets you transfer assets to whomever you want using beneficiary designations on the accounts you withdraw from.
No one single tool can give the best results. Not annuities, not the 4% rule, not stocks, not I-bonds or TIPs. The best plan is one which looks at all the risks, and balances all the risks.
