Weekly Hourly Calculator: Work Hours & Pay
The calculator for this page is switched off while it is checked. The formula is below, and the worked example in the article shows how to use it by hand.
This weekly hourly calculator works out your total work hours and gross pay for a week based on your hourly rate and the hours you worked each day. You enter your hourly wage and the hours (and optionally minutes) worked from Monday to Sunday, and it returns your total weekly hours and your gross weekly earnings before taxes and deductions.
Formula
The calculator uses two simple formulas:
- Total weekly hours = Monday hours + Tuesday hours + Wednesday hours + Thursday hours + Friday hours + Saturday hours + Sunday hours
- Gross weekly pay = Total weekly hours × Hourly rate
Where:
- Hourly rate is your pay per hour (in dollars, but the same math works for any currency).
- Each day’s hours is the number of hours you worked that day (entered as a decimal, e.g., 8.5 for 8 hours 30 minutes).
- Gross weekly pay is your earnings before taxes, insurance, retirement contributions, or any other deductions.
Worked Example
Using the default values from the calculator above: an hourly rate of $20.00, and 8 hours worked each day from Monday through Friday (40 hours total), with 0 hours on Saturday and Sunday.
- Add the daily hours: 8 + 8 + 8 + 8 + 8 + 0 + 0 = 40 hours.
- Multiply by the hourly rate: 40 × $20.00 = $800.00.
The calculator shows Total weekly hours = 40.00 and Gross weekly pay = $800.00.
Why Use a Weekly Hourly Calculator?
This tool is useful for anyone paid by the hour who wants a quick estimate of their weekly earnings. Common uses include:
- Checking a pay stub to verify that your gross pay matches the hours you recorded.
- Budgeting for the week or month based on a typical work schedule.
- Comparing job offers with different hourly rates and expected hours.
- Estimating overtime pay (see the note below on overtime).
- Planning for part-time or freelance work where hours vary from week to week.
The result is a gross figure—it does not include taxes, Social Security, Medicare, health insurance premiums, retirement plan contributions, or any other withholdings. Your take-home pay will be lower. For a more accurate net pay estimate, you would need to subtract those deductions, which vary by location and personal situation.
How to Read the Results
The first output, Total weekly hours, is simply the sum of all the hours you entered. The second output, Gross weekly pay, is that total multiplied by your hourly rate. Both are rounded to two decimal places.
If you work a standard full-time schedule (40 hours per week), the calculator will confirm that your gross pay is 40 times your hourly rate. If you work part-time or have an irregular schedule, the total hours will reflect that, and your pay will be proportional.
Remember that this is a pre-tax estimate. For example, with a $20 hourly rate and 40 hours, you get $800 gross. Your actual paycheck might be around $650–$700 after typical federal and state withholdings, but that varies widely.
Common Mistakes and How to Avoid Them
- Mixing up minutes and decimals: If you worked 8 hours and 30 minutes, enter 8.5, not 8.30. The calculator treats 8.30 as 8 hours and 18 minutes (since 0.30 of an hour is 18 minutes). To convert minutes to decimal hours, divide the minutes by 60. For example, 45 minutes = 45/60 = 0.75 hours.
- Forgetting to include all days: If you work a night shift that crosses midnight, count the hours on the day they were worked, not the day they ended. For example, a shift from 10 PM Tuesday to 6 AM Wednesday should be counted as 2 hours on Tuesday and 6 hours on Wednesday.
- Ignoring overtime: This calculator uses a straight hourly rate for all hours. If you are entitled to overtime (typically 1.5× your regular rate for hours over 40 in a week in the U.S., under the Fair Labor Standards Act), you would need to calculate that separately. For instance, if you work 45 hours at $20/hour, the first 40 hours are $800, and the 5 overtime hours are 5 × $30 = $150, for a total of $950. This calculator would show $900 (45 × $20), which undercounts your actual pay.
- Entering a zero hourly rate: If you are salaried or not paid by the hour, the pay result will be zero. This tool is only for hourly workers.
Limitations of the Formula
The formula assumes a simple, uniform hourly rate for all hours worked. It does not account for:
- Overtime rates (time-and-a-half, double-time, etc.)
- Shift differentials (e.g., higher pay for night or weekend shifts)
- Bonuses, commissions, or tips
- Paid time off (if you enter 40 hours but took a paid holiday, your pay might be the same, but your hours worked are less)
- Deductions (taxes, benefits, garnishments)
- Rounding rules some employers use for time clocks (e.g., rounding to the nearest 15 minutes)
For a precise paycheck, always refer to your employer’s payroll system or your pay stub. This calculator is a planning tool, not a substitute for official payroll calculations.
Frequently Asked Questions
How do I convert minutes to decimal hours for the calculator?
Divide the number of minutes by 60. For example, 7 hours and 30 minutes becomes 7.5 (30/60 = 0.5). 7 hours and 15 minutes becomes 7.25 (15/60 = 0.25). 7 hours and 45 minutes becomes 7.75 (45/60 = 0.75).
Does this calculator include overtime pay?
No. It multiplies all hours by your single hourly rate. If you work more than 40 hours in a week and are eligible for overtime, you need to calculate the overtime separately. For example, with a $15 rate and 45 hours, the base pay is 40 × $15 = $600, and overtime is 5 × $22.50 = $112.50, for a total of $712.50. The calculator would show $675 (45 × $15).
What is the difference between gross pay and net pay?
Gross pay is the total amount you earn before any deductions. Net pay (take-home pay) is what you actually receive after deductions like federal and state income tax, Social Security, Medicare, health insurance premiums, and retirement contributions. This calculator gives gross pay only.
Can I use this for a bi-weekly or monthly salary?
Not directly. This calculator is designed for a single week. To estimate a bi-weekly gross pay, multiply the weekly result by 2. For a monthly estimate, multiply the weekly result by 52 and then divide by 12 (since there are about 4.33 weeks in a month).
What if I work different hours each day?
That’s exactly what this calculator is for. Enter the actual hours for each day of the week, even if some days are 0. The total will be the sum of all entries.
Why does the calculator show a lower amount than my pay stub?
Your pay stub likely includes overtime, shift differentials, or other pay components that this simple calculator does not factor in. Also, if you are paid bi-weekly, your pay stub covers two weeks, not one. Check the pay period on your stub and compare accordingly.
