How a 401(k) changes your paycheck

Because traditional 401(k) money is taken before income tax, part of every dollar you save is effectively paid by the tax you no longer owe.

ContributionSaved per yearTake-home payPer monthIncome tax saved
None$0$87,455$7,288—
3%$3,600$84,825$7,069$970
6%$7,200$82,195$6,850$1,940
10%$12,000$78,689$6,557$3,234
15%$18,000$74,306$6,192$4,851
Putting 6% ($7,200) into a 401(k) only reduces your take-home pay by $5,260: taxes cover the other $1,940. Many employers also match part of it.

Single vs married filing jointly

Marriage changes the math: a couple filing jointly gets twice the standard deduction and brackets twice as wide as a single filer.

SingleMarried, one income
Federal income tax$17,570$10,040
State income tax$5,795$5,650

Take-home pay$87,455$95,130

Filing jointly would add $7,675 a year ($640 a month) to this household's take-home pay.
