Compare pay across time periods

Salary Calculator

Convert a gross pay rate into eight equivalents using your weekly schedule. Compare hourly wages with monthly or annual salary, and see the difference between every two weeks and twice a month.

Gross pay amount

Before taxes and deductions. Use any one currency, without its symbol.

Pay amount is

Biweekly means every 2 weeks; semimonthly means twice a month.

Scheduled hours per week

Workdays per week

Use a consistent weekly schedule: more than 0 and at most 168 hours, and 1–7 whole workdays. Hours cannot exceed 24 per workday. Breaks are not deducted automatically.

Comparison model: 52 weeks per year, with no unpaid leave or overtime premium. Results use the same currency as your input and do not estimate take-home pay.

Decimal places shown

Use a period for decimals. Properly grouped amounts such as 52,000 are accepted. Enter numbers without currency symbols or units.

Example: 25 per hour, 40 hours/week, 5 days/week → 52,000 per year.

Annual gross pay equivalent

Enter a pay amount and frequency, check your schedule, then select Calculate.

Worked pay comparisons

Hourly to annual

25 per hour, 40 hours per week

25 × 40 × 52 = 52,000

Gross annual equivalent is 52,000. Weekly pay is 1,000; monthly pay is ≈ 4,333.33. At 5 workdays per week, the daily equivalent is 200.

Pay frequency matters

2,000 each pay period

Biweekly: 2,000 × 26 = 52,000
Semimonthly: 2,000 × 24 = 48,000

The same amount paid every two weeks produces 4,000 more annually in this comparison than twice a month. These are different frequencies even though both can sound like “twice monthly.”

Different hours

39,000 annually over 30 hours/week

39,000 ÷ (30 × 52) = 25

The hourly equivalent is 25. With 4 workdays per week, the average day is 7.5 hours and daily pay is 187.50. The monthly equivalent remains 3,250.

How the conversion works

First, convert the entered amount to an annual equivalent. The annual multipliers are weekly hours × 52 for hourly pay, workdays per week × 52 for daily pay, 52 for weekly, 26 for biweekly, 24 for semimonthly, 12 for monthly, 4 for quarterly, and 1 for annual pay. Then divide that annual amount by each multiplier to obtain all eight equivalent rates.

Annual scheduled hours equal weekly hours × 52; annual scheduled workdays equal weekly workdays × 52. Average hours per workday equal weekly hours ÷ weekly workdays. This assumes a repeating schedule. The averages do not describe individual shift lengths or dates.

The fixed 52-week model makes comparisons consistent. It is not a universal payroll rule or a count of actual days in a calendar year. A year contains more than exactly 52 weeks, and the number of pay dates can depend on the calendar and an employer's schedule. This calculator does not count paychecks, handle a 53rd weekly or 27th biweekly pay date, or apportion salary across actual calendar months.

All amounts are gross equivalents in the currency you enter. Taxes, deductions, benefits, bonuses, overtime premiums, unpaid leave, holidays, and employer-specific payroll rules are not modeled. A straight-rate comparison does not determine what an employer owes or what will arrive in your account.

Pay can be zero. Weekly hours must be positive and no more than 168; weekly workdays must be a whole number from 1 to 7. Hours must fit within those workdays at no more than 24 hours per day. Inputs accept at most 64 characters, 15 integer digits, and 10 decimal places. Expressions, scientific notation, and currency symbols are not accepted.

Calculations keep exact fractions without intermediate rounding. Displayed decimals round halfway values away from zero and keep the chosen number of places. ≈ identifies a rounded result. Two decimal places is a display default, not a currency-specific payroll rounding rule; changing precision does not add a history entry.

Reference: U.S. Bureau of Labor Statistics — OEWS technical notes describes a 2,080-hour work-year convention for converting certain wage rates and explains exceptions. Our default 40 × 52 schedule also totals 2,080 hours, while this calculator lets you enter your own weekly hours.

Common questions

Are biweekly and semimonthly the same?

No. Here, biweekly means every two weeks, using 26 periods per comparison year. Semimonthly means twice each month, using 24 periods. Select the frequency described by your pay arrangement.

Why is monthly pay more than four times weekly pay?

Four weeks times twelve months is only 48 weeks. This calculator uses 52 weeks, so the average month is 52 ÷ 12, or 4⅓ weeks. A monthly equivalent is an annual amount divided by 12.

Does an annual salary divided by hours give my actual hourly wage?

It gives an arithmetic equivalent under the schedule entered. It does not change your employment arrangement or determine a contractual, legal, or overtime rate. Actual hours, pay dates, and payroll rules can differ.

Can I account for part-time hours or unpaid weeks?

You can enter part-time weekly hours. The model still repeats that schedule for 52 weeks and has no unpaid-weeks input. For a known annual gross total, select Annual and use it directly; the other results remain averages under the chosen 52-week schedule.

Why do I enter workdays if I already know weekly hours?

Workdays determine the daily equivalent and average hours per day. For hourly input, changing days alone does not change annual pay because the total weekly hours are unchanged. For daily input, the number of weekly workdays affects annual pay.
