Here is how the SRS is computed for a retiree whose MRA is age 56 and who retires under FERS with 30 years of civilian service and an estimated age 62 Social Security benefit of $1200 a month. 1  The FERS service is divided by 40. 2  The age 62 Social Security benefit is multiplied by the fraction derived above.
The IRS allows you to combine money in a SEP IRA with money in a 401(k) plan, either by moving the SEP IRA money to the 401(k) or the 401(k) money to the SEP IRA.
The only difference is that IRAs have much lower contribution limits than 401(k)s. In 2015, you can put up to $18,000 into a 401(k) (or up to 23,000 if you are age 50 or older) and $5,500 in an IRA (or up to $6,500 with the catch-up contribution).01k Plus Roth IRA. If you are making regular contributions to a 401k and are looking for another way to save even more retirement dollars, a Roth IRA is a great choice. Investors who qualify can contribute to both a 401k and a Roth IRA in the same year, and there are good reasons to do so.
