关于此工具

Enter your net self-employment profit (or, for an S corporation, your W-2 wages), your age and the year. The calculator subtracts half of your self-employment tax, applies the employee deferral limit, the employer 20% (or 25%) share and the catch-up amount, and compares the total with a SEP IRA.

单独企业或 LLC

Your plan earnings are net profit minus half of self-employment tax. The employer share is 20% of those earnings (the 25% rate, applied after the contribution itself is deducted). You can also defer up to $24,500 in 2026 ($23,500 in 2025) as an employee, up to your earnings.

公司

The employer share is 25% of your W-2 wages, and you defer from your wages. The compensation counted is capped at $360,000 in 2026 ($350,000 in 2025).

总限

Deferral plus employer money cannot exceed $72,000 in 2026 ($70,000 in 2025). Catch-up contributions are on top: $8,000 at 50 and over, $11,250 at ages 60 to 63 in 2026. A SEP IRA allows only the employer share, so a solo 401(k) usually lets you save more at modest incomes.

计算示例

A sole proprietor aged 45 with $100,000 of profit in 2026: half of self-employment tax is $7,065, plan earnings are $92,935, the employer share is $18,587 and you can add $24,500 of your own deferrals, for $43,087 in total. A SEP IRA would allow $18,587.
