The $100K Salary Advantage: Tax-Advantaged Accounts
At $100,000, maxing your 401(k) is particularly powerful:
| Contribution | Amount | Tax Savings (22% bracket) |
|---|---|---|
| 401(k) max ($23,500) | $1,958/mo | $5,170/yr savings |
| Roth IRA max ($7,000) | $583/mo | (post-tax, tax-free growth) |
| Combined | $2,541/mo | — |
Maxing a 401(k) at $100K salary means the equivalent of $23,500/year is invested before taxes — meaning you get to invest more with less out-of-pocket impact.
Comparison: HYSA vs. Invested Over 5 Years

| HYSA (4.5%) | Invested (7%) | |
