Let’s start with the 401k plans. For 2018, the IRS increased the contribution limits to $18,500, up $500 from $18,000 last year. The catch-up contribution for those age 50 or over remains unchanged at $6,000. $500 may not seem like much, but think of it this way – you get to give yourself a $500 raise!
For those interested in maxing out their 401k plans in 2018, here’s the breakdown depending on whether you’re paid monthly, 24 weeks per year or 26 weeks per year. If you’re paid monthly, the contribution is $1,541.66. This brings you just eight cents under the $18,500 max annually. If you’re paid 24 weeks per year, then the amount per paycheck is $770.83. If paid every 26 weeks, it’s about $711.53. For those over age 50 the breakdown is $2,041.66, $1,020.83, and $942.30 respectively.
Since contribution limits for IRAs remains unchanged, the maximum monthly amount is $458.33 (if saving monthly) and $541.66 for those age 50 and over. Of course, if you can save the $5,500 or $6,500 all at once at the beginning of the year, that’s ideal. If not, just max it out however you can.
Deductible IRA contributions phase-outs have changed as well. For single individuals covered by a workplace retirement plan, the income phase-out is $63,000 to $73,000. Married couples filing jointly, where the IRA contributor is covered by a workplace plan, the income phase-out is $101,000 to $121,000. For married couples filing jointly, here the IRA contributor is not covered by a workplace plan but their spouse is, the income phase-out is $189,000 to $199,000.
Finally, Roth IRA eligibility phase-outs have changed as well. For single (and head of household) individuals, the income phase-out is $120,000 to $135,000. For married filing jointly couples, the income phase-out is $189,000 to $199,000.
Ideally, a single individual (under age 50) with a 401k and IRA could save $24,000 annually if maxing out both. Married couples in the same situation could save $48,000. If over age 50, an individual could save $31,000 and a married couple could save $62,000 by maxing out both their 401k and IRA.
