How much will Roth IRA grow by retirement?
Contributing $7000 annually from age 25 to 65 at 8% average returns accumulates approximately $1.86 million completely tax-free. Starting at 35 the same contributions grow to only $830000. The 10-year head start more than doubles your retirement fund. This is why opening a Roth IRA should be one of your first financial moves after starting work.
Roth IRA vs Traditional IRA which is better?
Roth IRA is better if you expect to be in a higher tax bracket in retirement or if you are currently in a low bracket. Traditional IRA is better if you need the current tax deduction and expect lower retirement income. If unsure split contributions between both. Roth has the added advantage of no required minimum distributions and penalty-free withdrawal of contributions at any time.
Can I contribute to both 401k and Roth IRA?
Yes you can contribute to both a 401k and a Roth IRA simultaneously as they have separate contribution limits. The optimal strategy is: first contribute enough to 401k to get your full employer match then max out Roth IRA ($7000) then put remaining savings back into 401k up to its limit ($23500). This gives you both tax-deferred and tax-free retirement income.
