| Social Security | $6,200 | $7,440 | $1,240 |

What to do with it
If your 401(k) is not at the employer match, put the raise there first — that part is free money and nothing else in this comparison competes with it.
Beyond that, a dollar into a Section 125 benefit escapes Social Security and Medicare as well as income tax, while a dollar into a traditional 401(k) escapes only income tax. On a $20,000 raise that difference is worth $1,530.00 a year. This guide works it through.
Other raise sizes on the same salary
| Raise | Net gain a year | A month | You keep |
|---|---|---|---|
| $2,000 | $1,407 | $117.25 | 70.3% |
| $5,000 | $3,518 | $293.12 | 70.3% |
| $10,000 | $7,035 | $586.25 | 70.3% |
| $15,000 | $10,552 | $879.38 | 70.3% |
| $25,000 | $17,524 | $1,460.29 | 70.1% |
| $40,000 | $27,776 | $2,314.67 | 69.4% |
Putting it somewhere pre-tax instead
| Where it goes | Take-home change | What you have instead | Total value |
|---|---|---|---|
| All to salary | $14,070 | — | $14,070 |
| Half to a 401(k) | $6,270 | $10,000 in the plan | $16,270 |
| Half to a Section 125 benefit | $7,035 | $10,000 of benefits | $17,035 |
The Section 125 row wins the total-value column, because that route escapes Social Security and Medicare as well as income tax. The 401(k) row escapes income tax only. On the same money that difference is 7.65 cents in the dollar, and it is the reason to fill a health or dependent care election before adding to the 401(k) beyond the match.
