The number on the offer letter is wages. The federal extras are an employer FICA match (26 U.S.C. § 3111) and FUTA. On $52,000 of FICA-taxable wages (the $2,000 biweekly check from the take-home tool, times 26):
- Employer Social Security + Medicare: $3,978.00
- FUTA after the maximum 5.4% state credit: $42.00
- All-in: $56,020.00 (about 7.73% on top of wages)

Direct answer: $52,000 → $56,020
- Employer FICA = 6.2% × min(wages, $184,500) + 1.45% × wages
- On $52,000 that is $52,000 × 7.65% = $3,978.00
- FUTA = 0.6% × min(wages, $7,000) = $42.00
- Total cost = $52,000 + $3,978 + $42 = $56,020.00
Employee FIT withheld from the check is not an employer cost. That money was the employee's.
employer FICA = 6.2% × min(wages, $184,500) + 1.45% × wages FUTA = 0.6% × min(wages, $7,000) total cost = wages + employer FICA + FUTA
Checks you can re-run
| Annual wages | Employer FICA | FUTA | Total cost |
|---|---|---|---|
| $5,000 | $382.50 | $30.00 | $5,412.50 |
| $30,000 | $2,295.00 | $42.00 | $32,337.00 |
| $52,000 | $3,978.00 | $42.00 | $56,020.00 |
| $100,000 | $7,650.00 | $42.00 | $107,692.00 |
| $200,000 | $14,339.00 | $42.00 | $214,381.00 |
Below the $7,000 FUTA base, FUTA is 0.6% of wages ($5,000 → $30), not a flat $42. Above the $184,500 Social Security wage base, employer SS stops and Medicare keeps going. At $200,000: SS $11,439.00 + Medicare $2,900.00 = $14,339.00 FICA.
Split the employee share on the same wages with the FICA calculator. FUTA alone is on the FUTA page.
What this is not
- Not a 1099 burden. Contractors bill you; they pay SECA. See self-employment take-home.
- Not the employee's take-home. $2,000 biweekly, single, leaves $1,651.15: paycheck take-home.
- Not a net-to-gross offer letter. That inverse is paycheck gross-up.
On Social Security 6.2% (cap $184,500) and Medicare 1.45%, yes. The 0.9% Additional Medicare Tax is employee-only.
Full FUTA is 6.0% on the first $7,000 ($420). The maximum 5.4% state credit leaves 0.6% → $42 per employee per year, if the employer gets that credit.
No. Employer match is a plan cost, not a federal payroll tax. Employee deferral room is a different page: 401(k) contribution limit.
