The Salary Calculator converts a wage or salary across common pay periods so hourly, weekly, biweekly, semimonthly, monthly, and annual figures stay consistent. Enter one known amount and the hours or schedule assumptions, and the Salary Calculator returns the equivalent pay for every period plus an effective hourly rate when holidays or unpaid vacation change days worked.
Pay stubs and job offers rarely use the same period. Comparing an hourly quote with an annual salary without shared assumptions produces false gaps. This page keeps the conversion arithmetic explicit.

Convert your salary across pay periods
The Salary Calculator converts salary across pay periods by anchoring on an annual figure, then dividing or multiplying by the number of periods in a year. Period conversion answers what the same job pays when stated hourly, weekly, monthly, or yearly under one hours-per-week assumption.
Annual pay from an hourly wage is annual = hourly rate x hours per week x weeks per year. With $30 per hour, 40 hours per week, and 52 weeks, annual pay is 30 x 40 x 52 = $62,400. Monthly equivalent is $62,400 / 12 = $5,200. Weekly is $62,400 / 52 = $1,200. The Salary Calculator derives each period from that same annual total so the set does not drift.
If the job does not pay for a full 52 weeks, or hours differ from 40, change those inputs before comparing offers. A 40-hour assumption on a 35-hour role overstates annual pay.
Break a salary into every period
The Salary Calculator breaks a salary into every common payroll period from one shared annual total for the job. Daily, biweekly, and semimonthly amounts are easy to misstate when week counts or paycheck frequency labels on the offer are wrong.
From $62,400 annual: weekly = 62,400 / 52 = $1,200; biweekly = 62,400 / 26 = $2,400; semimonthly = 62,400 / 24 = $2,600; monthly = 62,400 / 12 = $5,200; quarterly = 62,400 / 4 = $15,600. Daily pay depends on days worked per year; using 260 weekdays (52 x 5) gives 62,400 / 260 = $240 per weekday on that schedule.
Biweekly and semimonthly are not the same. Twenty-six biweekly checks and twenty-four semimonthly checks both total the annual salary when math is consistent, but each check amount differs. The Salary Calculator labels both so a $2,400 biweekly figure is not treated as a semimonthly check.
Adjust for holidays and vacation
The Salary Calculator adjusts for holidays and vacation when those days change hours worked or unpaid time reduces annual pay. Effective hourly rate rises when salaried pay stays fixed while paid holidays reduce hours actually worked; unpaid time lowers annual pay and can lower the effective rate depending on how hours are counted.
Example: $62,400 salary, 40 hours per week, 10 paid holidays (80 hours) that are paid but not worked. Paid hours worked fall while annual pay stays $62,400, so effective hourly on hours worked is higher than the $30 headline used in the 40 x 52 model. Separately, unpaid vacation or unpaid leave reduces annual cash: two unpaid weeks at the $1,200 weekly rate remove $2,400, leaving $60,000 annual cash if no other changes occur.
Employers differ on whether holidays are paid, whether vacation accrues, and how overtime is calculated. The Salary Calculator applies the holiday and unpaid-day counts entered; it does not encode a single employer's handbook.
Overtime is separate from the base conversion. Time-and-a-half on hours above 40 raises pay above the straight annual figure from hourly x 40 x 52. Enter only base schedule hours for the standard conversion, then add overtime earnings outside that path when comparing total cash earned in a busy month.
Part-time schedules use the same formulas with fewer hours. At $30 per hour, 20 hours per week, and 52 weeks, annual pay is 30 x 20 x 52 = $31,200, half the full-time example when hours are exactly half. Do not annualize a short contract by pretending 52 weeks if the job ends after 26 weeks; use weeks actually paid.
Frequently asked questions
How do you convert hourly pay to annual salary?
Annual salary is hourly rate times hours per week times weeks per year. The Salary Calculator uses that product as the annual anchor. At $30 x 40 x 52, annual pay is $62,400.
What is the difference between biweekly and semimonthly pay?
Biweekly pay uses 26 periods per year; semimonthly pay uses 24. The Salary Calculator divides annual pay by 26 or by 24 accordingly. On $62,400, biweekly is $2,400 and semimonthly is $2,600.
How are monthly and weekly amounts calculated?
Monthly amount is annual divided by 12; weekly amount is annual divided by 52 when a full year of weekly pay is assumed. The Salary Calculator keeps both tied to the same annual total.
How do paid holidays affect effective hourly rate?
Paid holidays keep salary the same while reducing hours worked, which raises effective hourly pay on hours actually worked. The Salary Calculator applies the holiday hours entered. Unpaid time reduces annual cash instead.
Does this include taxes or benefits?
No. The Salary Calculator converts gross pay across periods. Tax withholding, retirement deferrals, and benefits need separate calculations.
How does this relate to the Hourly to Salary Calculator?
The Hourly to Salary Calculator on QuickCalculators focuses on the hourly-to-annual path. This page converts across the full set of periods and adjusts for holidays and unpaid vacation. Use either entry point; the math should agree when hours and weeks match.
How should overtime be handled?
Keep overtime out of the base period conversion. Convert the straight-time rate and schedule first, then add overtime pay for the periods when it was earned. Mixing overtime into the hourly base overstates every period's equivalent when overtime is irregular.
What if the offer states only monthly pay?
Treat monthly pay as annual / 12 and multiply by 12 to get annual, then derive weekly and hourly from that annual figure with the hours assumption. The Salary Calculator keeps the chain consistent when monthly is the only published number.
Summary
The Salary Calculator anchors on annual pay, so $30 per hour at 40 hours and 52 weeks is $62,400 per year, $5,200 per month, $1,200 per week, $2,400 biweekly, and $2,600 semimonthly. Holiday and unpaid-vacation inputs change effective hourly rate or annual cash when days worked differ from a plain 40 x 52 model.
Biweekly and semimonthly checks differ because 26 and 24 periods split the same annual total differently. These results are estimates for information only, not payroll advice.
