Define the hours and paid weeks first
Gross pay is compensation before deductions. To convert an annual salary to an hourly equivalent, divide it by hours per week multiplied by paid weeks per year. To annualize hourly pay, multiply the hourly rate by those same two quantities.
The word “paid” matters. A regular schedule, unpaid time away and paid leave can produce different annual totals. The calculator does not determine overtime eligibility or turn a salary into an hourly employment contract. Bonuses, variable schedules, benefits and unpaid work can also make two jobs with the same arithmetic hourly equivalent different offers.
For a fixed annual salary, reducing the entered paid weeks raises the hourly equivalent because the same annual amount is divided across fewer hours. For a fixed hourly rate, reducing paid weeks lowers annualized earnings. Those are different experiments; changing the mode changes which number is held constant.
- paid weeks
- weeks that are actually paid
- hours
- hours in each paid week
Worked example
Worked gross-pay example: $30 an hour
At $30 per hour, 40 hours per paid week and 52 paid weeks, annual gross pay is $62,400. Dividing by twelve gives a $5,200 monthly average; dividing by twenty-six gives $2,400 biweekly; dividing by fifty-two gives $1,200 per paid week.
Biweekly means every two weeks in this annualized convention. Semimonthly means twice a month: twenty-four payments per year, or $2,600 here. The calculator’s biweekly result uses twenty-six; it is not a semimonthly paycheck. The semimonthly row below is a separate arithmetic comparison.
A monthly average is useful for comparing annual income with annualized expenses, but it is not the cash received in every calendar month. The weekly display uses the entered number of paid weeks. When that differs from fifty-two, weekly and calendar-average figures need not share the same denominator.

- $30 per hour

| Period | Gross amount |
|---|---|
| Annual | $62,400.00 |
| Monthly average | $5,200.00 |
| Biweekly (26) | $2,400.00 |
| Semimonthly (24) | $2,600.00 |
| Paid week (52) | $1,200.00 |
| Hour (40 hours × 52 weeks) | $30.00 |
$62,400 gross; 40 hours per paid week; 52 paid weeks. Semimonthly is a manual comparison, not a calculator output.
Gross wages, taxable income and tax are different layers
Federal taxable income starts from modeled wages after entered qualifying pretax deductions, then subtracts the selected year’s standard deduction, with a floor at zero. The standard deduction is not cash withheld from a paycheck: it reduces the amount to which income-tax brackets apply.
A marginal tax rate applies to the next dollar within a particular bracket. It does not apply to every dollar of gross pay. An effective income-tax rate divides the calculated income tax by a named income measure, such as gross wages. Including FICA in the numerator would describe a different combined-tax rate, so a label needs to state which taxes it counts.
The following dated example isolates the numerical tax assumptions. The gross-pay conversion above remains useful independently of a tax year.

2026 example: one worker, single, $75,000 gross
Assume ordinary annual wages of $75,000, single filing status, the base standard deduction, and no pretax deductions, credits or other income. The 2026 standard deduction is $16,100, leaving $58,900.00 of federal taxable income.
The bracket slices are $12,400 at 10%, the next $38,000 at 12%, and the remaining $8,500 at 22%. Federal income tax totals $7,670.00. The marginal rate in this example is 22%; federal income tax divided by gross wages is about 10.23%, not 22% of all wages.
Employee Social Security is 6.2% of covered wages up to the 2026 wage base of $184,500. Employee Medicare is 1.45% without that wage cap. Here Social Security is $4,650.00 and Medicare is $1,087.50, leaving a modeled annual net of $61,592.50. State and local taxes and other payroll deductions are excluded.IRS · SSA · IRS

Single worker, standard deduction, no pretax deductions. Excludes state/local taxes and other payroll deductions. The standard deduction reduces taxable income, not cash pay.

2026 deduction and Additional Medicare examples
For the same $75,000 worker, enter $10,000 of traditional 401(k) deferrals and $2,000 of qualifying health-benefit deductions. The model reduces federal wages by both amounts, but FICA wages only by the qualifying health amount. Federal taxable income becomes $46,900.00; federal tax is $5,380.00, Social Security $4,526.00, and Medicare $1,058.50. After the $12,000 of deductions, modeled net is $52,035.50.
Traditional employee retirement deferrals generally remain subject to Social Security and Medicare taxes. MoneyBasis assumes health and other pretax inputs qualify for cafeteria-plan treatment that excludes them from federal and FICA wages. Actual benefit eligibility matters; not every deduction receives that treatment. The calculator does not validate plan eligibility or contribution limits.
Additional Medicare tax is 0.9% above the applicable wage threshold: $200,000 for single and head-of-household filers, and $250,000 for married filing jointly. At $300,000 of single-worker Medicare wages, regular Medicare is $4,350 and the additional amount is $900, totaling $5,250. Employer withholding begins above $200,000 of that employee’s wages regardless of filing status, so withholding and final liability can differ.IRS · IRS · IRS
What this estimate does and does not represent
MoneyBasis models one worker’s annual federal ordinary-wage income tax and employee FICA for a supported selected year, using the base standard deduction. Selecting married filing jointly does not add spouse wages or apply a separate Social Security cap to a second worker.
It is not W-4 withholding software or a complete tax return. It excludes state and local taxes, credits, itemized deductions, additional age or blindness adjustments, self-employment treatment, and special tips or overtime deductions. It also does not model every benefit, bonus withholding practice or payroll schedule.
Withholding is money paid toward tax during the year; liability is the tax calculated under the applicable rules. A refund or balance due depends on their relationship and on information beyond this model. For a monthly budget, actual take-home receipts can therefore be a more direct cash-flow input than dividing this simplified annual estimate by twelve.
Try it with your numbers
Try this:
For the gross example, choose hourly mode, $30, 40 hours and 52 paid weeks.
For the separate tax example, choose salary mode, $75,000, single and 2026 with deductions at zero.
Then add $10,000 traditional 401(k) and $2,000 qualifying health deductions and inspect the tax layers rather than only the net headline.
