Re: ROTH 401(k) calculator
The problem with estimators like these are that they ignore Social Security taxation in retirement. If you pay your taxes up front now, you can avoid the taxation of your Social Security benefits during retirement. Instead of paying up to a 46% marginal rate on your IRA withdrawals (due to the forced taxation of SS), you can take tax-free Roth income during retirement and tax-free Social Security during retirement.
You can thus retire to a higher standard of living..or retire earlier.
Also, in my opinion, tax rate HAVE TO RISE to pay for SS, Medicare, and Medicaid for boomers. You saw how difficult SS Reform was to change for future retirees..The only way we pay for boomers is to raise taxes or print more money resulting in higher tax rates or higher inflation.
