As of 6/21, the average LASERS benefit was 27,516/year. The pension is a 401(a). It is not subject to state income tax. Many members also have a 457(b), which is superior to a 401(k). Many also have other monies from IRA's, 401(k)'s, other 401(a)'s, 403(b)'s and other retirement vehicles, along with just regular investing in savings, stocks and bonds, etc. Some have Social Security, but that is often subject to WEP or in their spouse's case, GPO. A few, especially teachers in TRSLA, have annuities.
Also, some huge factors in retirement are debt load, monies from rental property or real estate sales and the lifestyle of the retiree.
Simple 401(k) balances may not be the best yardstick for how well someone does in retirement.
