As an hourly worker, your hourly rate is not the number that pays your rent. The number that matters is what actually lands in your bank account every Friday after taxes and FICA come out. This weekly paycheck calculator takes your hourly wage, your hours per week, and your estimated federal withholding rate, and breaks your gross pay into federal withholding, Social Security, and Medicare so you can see your true net weekly take-home pay in seconds — plus the equivalent monthly and biweekly amounts.
Type your hourly rate, set your hours and tax rate, and every figure updates instantly. The result card shows gross weekly pay, each deduction line, the net amount you would actually receive, and the annualized, monthly, and biweekly equivalents so you can plan any budget.
How to Use
- Enter your Hourly Wage — the gross rate your employer quotes you before any deductions. If you make $25 an hour, type 25.
- Set Regular Hours / Week to your scheduled straight-time hours. The default of 40 is full-time; drop it to 20 or 30 for part-time.
- Set Federal Withholding Rate to match your bracket. The default of 12% fits most hourly earners in the 10–12% brackets; raise it to 22% or higher if you are a higher earner or want a conservative estimate.
- The calculator multiplies the rate by your hours to get gross weekly pay. It then subtracts the federal withholding, Social Security at 6.2%, and Medicare at 1.45%.
- The remaining figure is your net weekly take-home pay. The card also projects annual, monthly, and biweekly equivalents — both gross and net — so you can match them to your rent, loan, and savings plans.
Because this model uses flat percentage rates rather than the full IRS withholding tables, it is a close planning estimate, not a payroll-grade figure. Your real paycheck will also reflect your W-4 allowances, any pre-tax 401(k) or health insurance contributions, and state income tax — none of which are modeled here.
How the Math Works
The calculation is deliberately transparent:
- Gross weekly pay = hourly wage × hours per week. At $25/hour and 40 hours that is $1,000.
- Federal withholding = gross × tax rate. At the default 12% on $1,000 that is $120.
- Social Security = gross × 6.2%. On $1,000 that is $62.
- Medicare = gross × 1.45%. On $1,000 that is $14.50.
- Net weekly pay = $1,000 − $120 − $62 − $14.50 = $803.50.
From the weekly figures, the other pay periods fall out:
- Annual gross = weekly gross × 52 = $52,000
- Annual net = weekly net × 52 = $41,782
- Monthly gross = annual gross ÷ 12 = $4,333.33
- Biweekly gross = annual gross ÷ 26 = $2,000
- Monthly net = annual net ÷ 12 = $3,481.83
- Biweekly net = weekly net × 2 = $1,607.00
Notice that FICA alone (7.65%) costs you $76.50 on a $1,000 week — more than many people expect — and the 12% federal estimate brings the total deduction to roughly 19.65% of gross. That is why an advertised $25/hour job feels more like $20/hour once the deposit clears.
Examples
Example 1 — The knowledge-base standard at $50/hour. This is the benchmark example used by payroll references: $50/hr × 40 hrs × 52 weeks = $104,000 annual gross, which splits into $4,000 biweekly and $8,666.67 monthly gross. At a 12% federal rate, the weekly check is $2,000 gross with $1,607 net — or about $83,564 a year after tax.
Example 2 — A standard retail or warehouse job at $18/hour. Gross weekly pay is $720. Federal withholding at 12% takes $86.40, Social Security $44.64, and Medicare $10.44. Your net weekly paycheck is $578.52, or about $30,083 a year after tax.
Example 3 — A skilled trade at $35/hour. Gross weekly pay is $1,400. Federal withholding is $168, Social Security $86.80, and Medicare $20.30. You take home $1,124.90 per week, roughly $58,495 a year. The dollar amounts grow, but the effective deduction rate stays near 19.65% because the model uses flat rates.
Example 4 — A higher earner at $100/hour. Gross weekly pay is $4,000. After $480 federal, $248 Social Security, and $58 Medicare, net pay is $3,214 per week. If your real bracket is higher than 12%, raise the tax-rate field to 22% or 24% for a more conservative estimate. In reality, once annual earnings pass the Social Security wage base, the 6.2% stops applying — so a real high earner would take home slightly more than this estimate.
FAQ
How is my weekly paycheck calculated?
Your gross weekly pay is your hourly wage multiplied by 40 hours. The calculator then subtracts an estimated 12% federal withholding, 6.2% for Social Security, and 1.45% for Medicare. What remains is your net weekly take-home pay.
Why does the calculator use a flat federal rate?
Most hourly workers fall into the 10% or 12% federal income tax brackets after the standard deduction, so the default of 12% is a reasonable planning estimate. You can raise it to 22% or 24% if you are a higher earner or want a conservative estimate. Your actual withholding depends on your W-4 elections, filing status, pre-tax deductions, and the IRS withholding tables — use your most recent pay stub to compare.
What is FICA and why is it on my paycheck?
FICA stands for Federal Insurance Contributions Act. It is two taxes: Social Security at 6.2% for retirement and disability benefits, and Medicare at 1.45% for health coverage in retirement. Together they take 7.65% of every dollar you earn, and your employer pays a matching 7.65% on top.
Does this calculator account for state income tax?
No. This model estimates only federal withholding and FICA. If you live in a state with income tax (California, New York, Illinois, and many others), your real net pay will be lower. States like Texas, Florida, Washington, and Nevada have no state income tax, so this estimate will be closer to your actual deposit.
What if I work overtime or part-time hours?
Set the Regular Hours / Week field to your straight-time schedule (default 40). For part-time work, drop it to 20 or 30 and every gross and net figure rescales automatically. Overtime at 1.5x is not modeled here — if you routinely work extra hours, add the premium manually (extra hours × your rate × 1.5) and then apply the same deduction percentages to the combined gross.
How much will I actually take home on payday?
This estimate is typically within a few percent of your real check for workers earning $15–$40 an hour who take the standard deduction and have no pre-tax benefits. Expect small differences from your W-4 choices, 401(k) contributions, health insurance premiums, and any local taxes.
Disclaimer
This weekly paycheck calculator is provided for informational purposes only and does not constitute tax, payroll, or financial advice. Figures are estimates based on flat percentage assumptions (12% federal, 6.2% Social Security, 1.45% Medicare) and a standard 40-hour week; actual withholding varies by filing status, W-4 elections, pre-tax benefits, state and local taxes, and the IRS withholding tables. Always verify your true take-home pay with your employer's pay stub or a licensed payroll professional.
