<prompt> Human: Im a 30-something increasingly aware of my approach to middle age and starting to think about my retirement. Ive always followed the accepted guidance on how to prepare your finances as a new wage earner: maxed out the 401k contribution to the level of the employer match, even increasing in the last couple of years to plow a total of 15 of my salary. Im curious, though, if there are any rules of thumb on how much a typical earner should have savedaccrued in their 401Kother retirement to be on track for their goals. Are there online calculators that PF recommends to stress test their 401k balancescontributionsreturns? Some sort of amortization schedule that advises where a typical plan should be at various ages per dollar per year of retirement income? Any other ways to think about 401k balances in context of gauging progress?Im barely literate in the retirement investing space. Tried a financial advisor last year and wasnt pleased with the guidance I had received. Really hope PF can be a solid resource as I start to take this stage of my life more seriously. Thanks in advance!EDIT TO ADD: Current age - 35Goal retirement age - 65 if I could manage 60, that would be cool... but job is not physically demanding, so no barriers to a long career other than the risk of being let go if my job can be done by a cheaper guy some dayGoal retirement income - could be off, but I feel fairly certain my wife I could live off 80-100K per year adjusted for inflationOther confounding variable - wife is a teacher with a pension plan to the extent I believe well enjoy those benefits, I really dont know... I mostly work on the assumption those wont be coming inAlso, a word  <response>: Fidelitys rules of thumb
