Work & Pay Calculators
Total work hours, compare salary and hourly offers, estimate a raise or annual gross income, and calculate overtime or mileage amounts. Choose the task below, then use its guide to check the method and assumptions.
Which work or pay task do you need?
Start with one task. Each tool has a guide explaining its inputs and limits.
Total shifts and unpaid breaks
Add daily or overnight shifts and subtract the unpaid breaks you enter. Use the total hours when comparing pay.
Compare salary with an hourly offer
Convert gross salary and hourly pay using your hours and weeks. Compare benefits and paid leave separately.
See what a raise changes
Compare current and proposed gross pay using a percentage, a flat increase or a new amount.
Estimate income with variable pay
Combine base pay with separately entered overtime, bonuses and commissions for an annual gross estimate.
Estimate regular and overtime pay
Use regular and overtime hours, an hourly rate and the multiplier that applies to your estimate.
Calculate a dated mileage amount
Use U.S. IRS rates for the trip date and purpose, with parking, tolls and a dated trip log. Check eligibility separately.

How to Calculate Work Hours With Breaks and Overnight Shifts
An overnight shift crosses midnight, so a simple clock-time subtraction can produce the wrong total. Follow an example that accounts for the date boundary, unpaid breaks, and decimal hours, then check which pay rules apply to your situation.
How to Calculate a Pay Raise: Percentage, Amount or New Pay
A raise can be quoted as a percentage, a flat amount or a new pay figure. See how all three describe the same change, why the old pay is the percentage baseline, and what an hourly raise means in annual gross pay.
Salary vs. Hourly Pay: Compare the Same Gross Pay
An hourly equivalent depends on the hours and paid weeks you assume. Compare offers on the same gross-pay basis, then check benefits, overtime and other terms that a simple conversion leaves out.
How to Calculate Overtime Pay: Hours, Rate, and Rules
Calculate gross pay by separating regular hours from overtime hours and applying the multiplier you select. The arithmetic does not determine which pay rules apply.
How to Estimate Annual Income with Variable Pay
Start with base pay, then add overtime or variable compensation only as an estimate based on the schedule or figures you enter.
How to Calculate Mileage Reimbursement
Mileage reimbursement arithmetic is miles multiplied by a selected rate. The rate may come from an employer policy or another applicable source, so check the rules for your situation.
How to use the results together
If your hours vary, total a representative week with theTime Card Calculator, then enter that schedule into the Salary to Hourly Calculator. The tools work separately; values are not transferred automatically. Read the salary versus hourly guidebefore comparing offers with different benefits or paid leave.
For a proposed increase, compare the base amounts in thePay Raise Calculator. If overtime, bonuses or commissions also matter, build a separate gross estimate in the Annual Income Calculator. Its variable-pay guide explains how to avoid counting the same earnings twice.
Payroll Calculations & Schedule Examples
The 2,080-Hour Annual Benchmark
A common planning assumption is 2,080 annual hours, calculated as 40 hours per week for 52 weeks. This is an example schedule, not a universal or international payroll standard:
40 hours/week × 52 weeks/year = 2,080 hours/year
Paid leave, unpaid leave, holidays, and actual schedules affect the hours relevant to a comparison. If you work 40 hours per week for 50 weeks, for example, the schedule totals 2,000 hours (40 × 50). Use the hours and weeks that match your own situation. For a fixed salary, changing comparison weeks changes the hourly equivalent without reducing annual pay. If unpaid leave reduces earnings, enter the reduced annual amount. Thesalary-to-hourly method and examplesexplain this distinction.
Biweekly (26 Checks) vs. Semi-Monthly (24 Checks)
Biweekly and semi-monthly pay describe different schedules. Both may result in roughly two paychecks per month, but the number of periods and amount per check differ for the same annual salary:
- Biweekly pay: A schedule every two weeks has 26 periods in a 52-week planning year. Depending on pay dates, some calendar months may include three checks. Actual payroll calendars can differ from the standard comparison counts used by the calculators.
- Semi-monthly pay: A schedule twice each calendar month has 24 pay periods per year (
12 × 2). With the same annual salary divided evenly, each check is larger than a biweekly check because there are fewer pay periods.
Decimal Hours vs. Minute Formats
Time cards must be converted into decimal hours before multiplying by an hourly wage. A common error is entering 8 hours and 15 minutes as 8.15 rather than the mathematically correct 8.25 hours:
| Minutes Worked | Fraction of an Hour | Decimal Hour Equivalent |
|---|---|---|
| 15 minutes | 15 / 60 = 1/4 | 0.25 hours |
| 30 minutes | 30 / 60 = 1/2 | 0.50 hours |
| 45 minutes | 45 / 60 = 3/4 | 0.75 hours |
| 6 minutes (1/10th) | 6 / 60 = 1/10 | 0.10 hours |
Browser-Side Pay Calculations
Work and pay calculations run in your browser. Normal page and asset requests still reach the site host; optional analytics, if accepted, measure visits and tool use without pay or work-hour values.
- Browser processing: Each calculation executes directly on your device via client-side JavaScript.
- Calculation values: Entered wages, salaries, work hours, and results are not sent as analytics events.
- Local recovery: Tool inputs are saved in this tab's browser session storage for refresh recovery. The mileage trip log can also be saved in local browser storage for later visits. Use Reset to clear the current tool's saved data; see thePrivacy Policy for details.
