Direct answer: $20 × 40 → $664.88
- Period wages = $800.00 (52 periods)
- Annualize = $41,600
- Pub 15-T single table: last dollars sit in the 12% band (that slice starts at $19,900 and runs to $57,900)
- This check FIT = $73.92
- FICA = 6.2% + 1.45% = $61.20
- Net = $800.00 − $73.92 − $61.20 = $664.88
Frequency myths on $52,000: biweekly vs semimonthly. Federal floor is still $7.25 on the federal minimum wage calculator. $20 is a common advertised rate, not that floor.
FIT = Pub 15-T percentage method on annualized wages
FICA = 6.2% Social Security (wage base $184,500) + 1.45% Medicare
net = gross − FIT − FICA − pre-tax deductions
Same $800, three statuses
| Status | FIT | FICA | Net |
|---|---|---|---|
| Single | $73.92 | $61.20 | $664.88 |
| Head of household | $53.31 | $61.20 | $685.49 |
| Married (one income, Step 2 off) | $42.88 | $61.20 | $695.92 |
FICA does not care about filing status on this engine. The gap is FIT. Single and HOH last dollars are in the 12% band. HOH 12% starts at $33,250. Married $41,600 is still in the 10% band (married 12% starts at $44,100).
Same $41,600 single, four calendars
| Frequency | Gross | FIT | FICA | Net |
|---|---|---|---|---|
| Weekly (52) | $800.00 | $73.92 | $61.20 | $664.88 |
| Biweekly (26) | $1,600.00 | $147.85 | $122.40 | $1,329.75 |
| Semimonthly (24) | $1,733.33 | $160.17 | $132.60 | $1,440.56 |
| Monthly (12) | $3,466.67 | $320.33 | $265.20 | $2,881.14 |
Two weekly nets are $1,329.76. The biweekly stub is $1,329.75. Same year. Different slice. A penny of rounding, not a raise.
What this is not
- A $15 leftover. Forty hours at $15 is $600 and nets $504.18. This page starts at $20.
- A $7.25 federal-floor page. $20 × 40 is $800. $7.25 × 40 is $290. Run the federal minimum wage calculator if the question is the FLSA cash wage.
- Proof your state uses $20. Several states sit above $15. This stub is the federal engine only.
- A 1040 effective-tax page. This is Pub 15-T on the stub. Single leftover at a higher salary: effective FIT on $100,000.
It is the federal-plus-FICA estimate for $800 weekly, single, clean W-4. Benefits, 401(k), and state tax change the deposit.
The married table is wider in the 0% and 10% slices. $41,600 married is still 10%. $41,600 single has been in 12% since $19,900.
No. Annual FIT stays $3,844. The four nets above all land near $34,574.
