Hourly Pay Calculator: How to Work It Out

This calculator works out your total earnings for a given number of hours at a set hourly rate, and it also shows your weekly, monthly, and annual pay based on those figures. You enter your hourly wage, the hours you work per week, and the number of weeks you work per year, and you get back your gross pay for each period. The result is your gross (pre-tax) income, so remember that your actual take-home pay will be lower after deductions.

Formula

The core formula is simple: multiply your hourly rate by the number of hours you work. To get weekly pay, use:

Weekly pay = hourly wage × hours per week

For annual pay, multiply that by the number of weeks you work in a year:

Annual pay = hourly wage × hours per week × weeks per year

Monthly pay is the annual pay divided by 12 (since there are 12 months in a year):

Monthly pay = (hourly wage × hours per week × weeks per year) / 12

Variables:

• Hourly wage – your gross pay per hour, in dollars (or your currency).
• Hours per week – the number of hours you work in a typical week.
• Weeks per year – the number of weeks you actually work per year (usually 52 for full-time, but less if you take unpaid leave).

All results are gross amounts before taxes, Social Security, Medicare, or other deductions.

Worked Example

Using the default values from the calculator: hourly wage = $20.00, hours per week = 40, weeks per year = 52.

1. Weekly pay: $20.00 × 40 = $800.00
2. Annual pay: $800.00 × 52 = $41,600.00
3. Monthly pay: $41,600.00 / 12 = $3,466.67

The calculator shows the same results: weekly $800.00, monthly $3,466.67, annual $41,600.00. This matches the formula exactly.

When to Use This Calculator

Use this calculator when you need to convert an hourly wage into a salary figure, or when you are comparing job offers. For example, if you are offered $25 per hour for a 35-hour week, you can quickly see the annual equivalent and compare it to a salaried position. It is also handy for budgeting: knowing your monthly gross pay helps you estimate what you can spend on rent, utilities, and savings.

This calculator is also useful for freelancers or part-time workers who want to see what their hourly rate translates to over a year. Just enter your typical hours and the number of weeks you actually work (remember to subtract vacation time or slow periods).

How to Read the Results

The numbers you get are gross pay – the amount before any deductions. Your net pay (take-home) will be lower because of federal and state taxes, Social Security, Medicare, and possibly health insurance premiums or retirement contributions. As a rough rule, many employees see their take-home pay be about 70–85% of gross, depending on their tax bracket and deductions, but this varies widely.

Also note that the monthly figure is an average. If you are paid bi-weekly (every two weeks), you will receive 26 paychecks a year, so some months you get two paychecks and some months three. The monthly average is still useful for budgeting, but your actual monthly deposits will vary.

Common Mistakes and Pitfalls

• Forgetting unpaid time off: If you take 2 weeks unpaid vacation, you should use 50 weeks per year, not 52. Using 52 overestimates your annual income.
• Mixing up gross and net: The calculator gives gross pay. If you compare it to a salaried offer that is also gross, you are fine, but if you compare to your bank deposits, you will be misled.
• Not accounting for overtime: If you work more than 40 hours a week and get overtime pay (often 1.5 times your regular rate), this simple calculator won’t capture that. You’d need to calculate overtime separately.
• Ignoring benefits: A job with a lower hourly rate but great health insurance and retirement matching may be worth more overall. This calculator only looks at cash pay.

Limitations of the Formula

This formula assumes a constant hourly rate and a fixed number of hours each week. It does not account for:

• Overtime pay (time-and-a-half or double time)
• Bonuses, commissions, or tips
• Paid time off (if you are paid for vacation, you still get those hours, so using 52 weeks is fine)
• Taxes and deductions
• Shift differentials (higher pay for night or weekend shifts)

For most full-time employees with a steady schedule, the formula is accurate to within a few percent. But if your hours fluctuate, you should use an average of your hours over several weeks to get a better estimate.

Hourly vs. Salary: What’s the Difference?

An hourly worker is paid a set amount for each hour worked, and typically receives overtime pay for hours beyond 40 per week. A salaried worker receives a fixed annual amount, regardless of the exact hours worked (though some jobs require more than 40 hours without extra pay).

When comparing a job offer that is hourly to one that is salaried, convert both to annual gross pay. For example, a $20/hour job at 40 hours/week for 52 weeks equals $41,600/year. If a salaried offer is $45,000/year, it is higher in cash terms, but consider the benefits, job security, and work-life balance.

Also remember that some salaried positions are exempt from overtime, meaning you might work 50 hours a week for the same pay. In that case, your effective hourly rate is lower than it appears.

Frequently Asked Questions

How do I calculate my hourly rate from a salary?

Divide your annual salary by the number of hours you work per year. For a typical full-time schedule, that is 40 hours/week × 52 weeks = 2,080 hours. So a $50,000 salary is about $24.04 per hour ($50,000 / 2,080). If you take unpaid leave, use fewer hours.

What is the difference between gross and net pay?

Gross pay is the total amount you earn before any deductions. Net pay is what you actually take home after taxes, Social Security, Medicare, health insurance, and retirement contributions are taken out. The calculator gives gross pay; your pay stub will show the deductions.

How many weeks per year should I use?

Use 52 if you are paid for all 52 weeks (including paid vacation and holidays). If you take unpaid time off, subtract those weeks. For example, if you take 3 weeks unpaid, use 49 weeks.

Does this calculator include overtime?

No, it assumes a flat hourly rate for all hours. If you work overtime, you would need to calculate overtime pay separately – typically 1.5 times your regular rate for hours over 40 per week in the U.S., but this varies by country and employment contract.

Is the monthly pay figure exact?

It is an average. If you are paid bi-weekly, you get 26 paychecks a year, so some months have two paychecks and some have three. The monthly figure is your annual pay divided by 12, which is useful for budgeting but not the exact amount you receive each month.

What if I work part-time or irregular hours?

Use your average hours per week over a typical month or quarter. For example, if you work 20 hours one week and 30 the next, your average is 25. Enter that as your hours per week. This gives a reasonable estimate, but your actual pay will vary.
