Salary Calculator
Convert gross pay between hourly, daily, weekly, biweekly, semimonthly, monthly and annual amounts using explicit work-schedule assumptions.
The calculation stays in your browser. Results are gross-pay equivalents before taxes and deductions. Currency changes formatting only; no exchange-rate conversion occurs.
How to use this tool
Compare recurring gross compensation across pay periods using one annualized value, your hours and days per week, and your working weeks per year.
Transparent method
Formula and method
Annual gross pay = hourly rate × hours per week × working weeks per year. Calendar-period equivalents use annual ÷ 12 monthly, ÷ 24 semimonthly and ÷ 26 biweekly.
Worked examples
- Hourly to annual: $30 × 40 hours × 52 weeks = $62,400 annual gross pay.
- Annual to hourly: $52,000 ÷ (40 hours × 52 weeks) = $25 per hour.
- Annual to calendar periods: $60,000 is $5,000 monthly, $2,500 semimonthly and about $2,307.69 biweekly.
- Biweekly versus semimonthly: $62,400 ÷ 26 = $2,400 biweekly, while $62,400 ÷ 24 = $2,600 semimonthly.
- Part-year schedule: $25 × 35 hours × 48 weeks = $42,000 annualized gross pay under the entered schedule.
Assumptions and limits
- All results are gross pay estimates before taxes and deductions. This calculator does not estimate take-home pay.
- Hourly, daily and weekly conversions use your entered hours per week, working days per week and working weeks per year.
- Biweekly means 26 periods, semimonthly means 24 periods and monthly means 12 periods in a full year.
- Hours default to 40, working days to 5 and working weeks to 52. These are editable assumptions, not payroll or legal rules.
- USD, GBP and CAD change display formatting only. No exchange-rate conversion occurs.
- Overtime premiums, bonuses, commissions, benefits, paid-time-off rules, taxes and deductions are excluded.
How the Salary Calculator works
The calculator first converts the entered recurring gross pay to one annual gross amount. Every displayed period is then derived from that same annual value, which prevents small differences caused by chaining rounded conversions.
Hourly, daily and weekly inputs are schedule-based. Biweekly, semimonthly and monthly inputs are calendar pay-period conversions using 26, 24 and 12 periods per year. Full JavaScript precision is retained until currency values are displayed.
Hourly to annual salary
Annual gross pay = hourly rate × hours per week × working weeks per year. At $30 per hour, 40 hours per week and 52 weeks, the annual gross equivalent is $62,400.
The result uses the hours and weeks entered without applying a separate overtime premium. Change working weeks if unpaid periods or part-year work should be reflected in the estimate.
Annual salary to hourly rate
Hourly gross equivalent = annual gross salary ÷ (hours per week × working weeks per year). A $52,000 annual salary divided by 40 hours and 52 weeks is $25 per hour.
This is a gross-pay comparison, not an employment-law determination of an employee's regular rate and not a take-home-pay estimate.
Monthly salary conversion
Monthly gross equivalent = annual gross salary ÷ 12. A $60,000 annual amount is $5,000 per month. Monthly pay is not the same as pay every four weeks: 12 calendar months and 13 four-week periods fit differently into a year.
Weekly salary conversion
Weekly gross equivalent = annual gross salary ÷ the working weeks per year entered. With 52 weeks, $62,400 is $1,200 per week. With 48 weeks, the same annual total has a larger weekly equivalent because it is spread across fewer working weeks.
Biweekly salary conversion
Biweekly gross equivalent = annual gross salary ÷ 26 under a standard full-year schedule paid every two weeks. A $60,000 annual amount is about $2,307.69 per biweekly period.
Semimonthly salary conversion
Semimonthly gross equivalent = annual gross salary ÷ 24 because semimonthly normally means two pay periods in each of 12 months. A $60,000 annual amount is $2,500 per semimonthly period.
Biweekly vs semimonthly pay
Biweekly and semimonthly are not interchangeable. Biweekly pay occurs every two weeks, usually 26 times per year. Semimonthly pay occurs twice per month, usually 24 times per year. For $62,400 annually, that is $2,400 biweekly versus $2,600 semimonthly.
Daily pay and work-schedule assumptions
Daily gross equivalent = annual gross salary ÷ (working days per week × working weeks per year). It does not divide by 365. At $42,000 across 5 days and 48 weeks, the daily equivalent is $175.
Hours per week, days per week and weeks per year are explicit because schedules vary. The defaults of 40 hours, 5 days and 52 weeks are starting assumptions only. Weeks can be reduced for seasonal or part-year work; paid vacation treatment depends on actual employment terms.
Gross pay versus net pay
Gross pay is compensation before taxes and deductions. Net or take-home pay is what remains after applicable taxes, retirement contributions, insurance and other deductions. This calculator converts gross recurring compensation only and does not calculate net pay.
No US, UK or Canadian payroll rules are applied. Choosing USD, GBP or CAD formats the same numeric amounts and does not imply tax-law support or perform foreign-exchange conversion.
What the calculator does not include
The estimate excludes separate overtime rates, bonuses, commissions, benefits, taxes, deductions and jurisdiction-specific payroll rules. It does not infer paid time off. Entered hours and rates are used as provided, without automatically applying a 1.5× overtime rate.
Common salary-conversion mistakes
Common errors include treating biweekly as twice monthly, treating monthly pay as every four weeks, dividing annual salary by 365 for a working-day rate, or assuming 52 working weeks when a contract has unpaid periods. Verify the pay-period definition and schedule before comparing offers.
Frequently asked questions
How do I convert hourly pay to annual salary?
Multiply the hourly rate by hours per week and working weeks per year. For example, $30 × 40 × 52 equals $62,400 in annual gross pay.
How do I convert annual salary to hourly pay?
Divide annual gross salary by hours per week multiplied by working weeks per year. $52,000 ÷ (40 × 52) equals $25 per hour.
How many pay periods are in a biweekly year?
The calculator uses 26 biweekly periods in a full year because biweekly means every two weeks.
Is biweekly the same as semimonthly?
No. Biweekly normally means 26 periods per year, while semimonthly means twice each month, or 24 periods per year.
How do I calculate monthly salary?
Divide annual gross salary by 12. Monthly pay is not the same as a four-week pay period.
Does this salary calculator include taxes?
No. It converts gross pay only and does not apply income tax, payroll tax, PAYE, National Insurance, state or provincial rules.
Does it calculate take-home pay?
No. Take-home or net pay depends on taxes and personal deductions that this gross-pay calculator does not model.
How many working weeks are in a year?
The default is 52, but it is editable up to 53. Use the number that fits your paid or working schedule; it is an assumption, not a legal rule.
Does the calculator include overtime?
No. It uses the rate and hours entered without applying a separate overtime premium because overtime rules vary by jurisdiction and employment terms.
Can I use fewer than 52 working weeks?
Yes. Enter fewer weeks to model seasonal, contract or unpaid periods. Hourly, daily and weekly equivalents will use that schedule.
