Those seeking a much more sophisticated retirement calculator, where you can set nearly every parameter, such as rate of return, amount saved, and nearly everything else, should checkout firecalc. You can select different withdrawl rate strategies, different investment strategies, deferred compensation strategies, different investment mixes, and many, many other things. The interface isn't as pretty, but it is unbeli…

I opened, there is too much info for my small brain to grasp and closed it. :-(

It models a bunch of different possible investment returns to show you how your money would fare over a long period.

I love the simplicity and the look of the UI. Unfortunately I think the simplicity means that very important parameters are being left out. Ideally, you should be able to specify estimated return rate and estimated inflation rate. Also, specifying the draw down rate would be nice... I've poured through a lot of these calculators recently as I've begun to get interested in FIRE... I think the most simple (but good) one is the AARP calc if you want a simple example.

Finally, and I think this is where it really falls short - this calculator is WAY TOO OPTIMISTIC out of the gate. I just cross checked it w/ my own calculations - it doesn't add up. Its "conservative" estimate is way higher than my "optimistic" plan (10% return / 3% inflation based on a passive index investing strategy)

This is a really good interface but the assumptions backing the results seem weak. The growth rate on conservative and aggressive portfolios are high. The recommended amounts of saving should be as % of income. Recommending someone that makes 100k save 100 dollars a month is not great. It's also sad that the maximum amount saved per month is 1k where even just maximizing 401k is 1.5k a month.

Nice to see your income rise so much just before you die and a lawyer gives it all away. Alas “the old have the means but no mobility, and the young have the mobility but no means”

What are you even talking about? When you retire you stop accumulating savings and start spending it. At first it continues to grow but if you plan correctly you will have made good use of it by end of life. Then it will be depleted.

By the time you retire you have more capital accruing interest, and generally more to invest in the attendant better investment opportunities available. That's what they meant.

All this does is scare me. I honestly hope I die before I have to retire, because there's no way I'm going to have saved enough money to live off of, even modestly, and no way I'm going to remain sharp enough to continue earning through and beyond my 60s.

Pay off a modest $100k house in a low cost of living area and you should be able to survive on Social Security alone. Save more if you can though.

Social security is a supplement, it’s not meant for you to live off, nor should you expect it to always be around.

Be careful with this: The projections are gross (ie not inflation-adjusted) and the advice buried in the explanatory text below does not sufficiently discuss this issue. It says you can do a "simple" calculation by applying one year's worth of inflation versus a compounded rate of return. Assuming historical inflation rates, the value of the savings it projects will be significantly eroded compared to what it shows.

Edit: And as others have pointed out below, the returns assumed are unrealistically optimistic. Be warned about basing your retirement planning on this.

>>> Take your total retirement savings and multiply it by 3%. For example, if you have $1.25m (retirement savings), multiplied by 0.03% (inflation), you get $45,000 in inflation. Then you subtract that number from your total savings: $1.25m - $45k = $880k. This will give you a baseline to understand your financial situation.

I don't fully understand... 1.25M - 45k is most definitely not 880k. Did you do something else that you forgot to list?
