About the Payroll Calculator
Running payroll means turning hours worked into a paycheck that correctly reflects earnings, mandatory withholdings, and take-home pay. This calculator does that for an entire team at once. For each employee you enter an hourly rate, regular hours, and overtime hours, and it produces gross pay, total tax deductions, and net pay, then rolls everything into company-wide totals at the bottom.
The estimates use standard percentages so small employers can sanity-check a pay run or forecast labor cost before submitting to a payroll provider. It is meant for planning and verification rather than as a substitute for a certified payroll service, because real withholding depends on each worker's W-4 elections, filing status, and year-to-date earnings. Still, seeing gross, deductions, and net side by side across the whole roster is exactly what most owners need to budget cash flow.
How the Payroll Calculator works
Gross pay is regular pay plus overtime pay. Regular pay equals rate times regular hours. Overtime pay equals rate times 1.5 times overtime hours, reflecting the standard time-and-a-half premium. So an employee at $20 with 40 regular and 8 overtime hours earns (20 x 40) + (20 x 1.5 x 8).
Four deductions are applied to gross pay at fixed rates: federal income tax at 12%, state income tax at 5%, Social Security at 6.2%, and Medicare at 1.45%. Combined, that is 24.65% withheld. Net pay is gross minus the sum of those four. Social Security and Medicare are true FICA rates; the income tax figures are flat estimates and will differ from a worker's actual bracket and allowances.
Worked example
Take Bob Johnson from the starter data: rate $20, 40 regular hours, 8 overtime hours. Regular pay is 20 x 40 = $800. Overtime pay is 20 x 1.5 x 8 = $240. Gross pay is $1,040.
Deductions total 24.65% of $1,040, which is $256.36 (federal $124.80, state $52.00, Social Security $64.48, Medicare $15.08). Net pay is $1,040 - $256.36 = $783.64. Across the three sample employees, the company totals row sums every column so you can see the full cash outlay for the pay period at once.
Tips & common mistakes
- The 12% federal rate is a flat estimate; an employee claiming dependents or filing jointly may have far less withheld, so treat net pay here as approximate rather than exact.
- Social Security stops at the annual wage base (about $168,600 in recent years). High earners who cross it late in the year will have that 6.2% overstated by the flat rate used here.
- Enter overtime hours in the OT column, not lumped into regular hours, or the 1.5x premium will be missed and gross pay will be understated.
- Remember this shows employee-side deductions only. As the employer you also owe matching Social Security and Medicare plus federal and state unemployment, so your true cost per employee is higher than gross pay.
- Adjust the state rate to match where the employee actually works; several states have no income tax at all, in which case set it to 0%.
Payroll Calculator: frequently asked questions
Why is my net pay slightly different from my real paycheck?
This tool uses flat estimated rates for income tax, while your employer withholds based on your W-4, filing status, and cumulative earnings using IRS tables. FICA (Social Security and Medicare) should match closely, but the income tax portion is an approximation, so expect small differences.
Does it calculate the employer's share of payroll taxes?
No. The deductions shown come out of the employee's gross pay. Employers separately pay a matching 6.2% Social Security and 1.45% Medicare, plus FUTA and state unemployment. Budget roughly 7.65% on top of gross for the employer FICA match alone.
How should salaried employees be entered?
Convert the salary to an equivalent hourly rate and use 40 regular hours per week (or the person's standard schedule). For a $52,000 salary, that is roughly $25 per hour. Exempt salaried staff generally do not receive overtime, so leave OT hours at zero.
Are pre-tax deductions like health insurance or 401(k) included?
No. The calculator applies taxes directly to gross pay. In reality, pre-tax benefits reduce taxable wages before withholding, which would lower the tax amounts. Subtract those contributions from gross first if you want a closer estimate.
Can I change the tax percentages?
The rates are fixed in this version to keep results consistent and are shown in the assumptions box. If your state or situation differs materially, use the tool for the gross-pay math and apply your own withholding rates separately.
