If you are an employee or an independent contractor paid by the hour, converting your hourly income into an annual salary can be advantageous. You often need to provide your yearly earnings in application forms, or you might want to compare salaries between new job opportunities. In any case, you can determine your annual salary using simple formulas and basic math knowledge.
Steps
When the number of working hours per week is consistent
Determine your hourly wage. You likely already know how much you earn per hour. For example, you might earn 90,000 VND per hour. If you're unsure, find out this information.
- Your hourly wage is usually listed on your pay stub if your employer provides one.
- If you're uncertain, you can also ask your manager or someone from the HR department.
Calculate the total number of hours you work each year. Multiply the number of hours you work per week by 52, as there are 52 weeks in a year.
- For example, if you work 40 hours per week, your calculation would be: 40 hours x 52 weeks = 2080 hours in a year.
Multiply your hourly wage by the number of hours worked each year. Now, all you need to do is multiply the hours by your wage.
- Continuing the example above, 90,000 VND x 2080 = 187,200,000 VND. This is your annual salary.
When the number of working hours per week varies
Track your working hours. Record the number of hours you work each day. At the end of the week, calculate your total working hours.
- You can use an electronic app, online software, or simply write it down in a notebook.
- If your working hours vary weekly, track them over a longer period to calculate the average.
- For example, if you work 10 hours in the first week, 25 hours the next, 15 hours the following week, and 30 hours in the last week, you worked 80 hours that month. Divide this by 4 weeks to get an average of 20 hours per week.
- If your hours fluctuate significantly during different times of the year, track them over an even longer period. For instance, if you work 50 hours per week during the holiday season but only 20 hours per week in the summer, this variation will greatly impact your calculations. In cases of significant fluctuation, you may need to track your hours over an entire year for accurate data.
Determine your overtime hours. In the United States, if you work more than 40 hours in a 7-day period, your employer must pay you time and a half. In other words, you earn an additional half-hour wage for every hour worked beyond 40 hours per week. Vietnamese labor laws have similar regulations, though overtime pay varies depending on the day (weekdays, weekends, or holidays).
- The formula for this calculation is: Total paid working hours per week = Actual hours worked + [0.5 x (actual hours worked - 40)]
- For example, if you work 45 hours in a week, you have 5 overtime hours. Multiply 5 by 0.5 to get 2.5 additional hours. Add this to your 45 regular hours, resulting in 47.5 paid hours instead of 45.
Calculate your annual working hours. To find this number, multiply your average paid weekly working hours by 52. For example, if you typically work 45 hours per week, multiply 47.5 hours (adjusted for overtime) by 52. The result is 2,470 hours per year.
- If you track your working hours over an entire year, simply add them up instead of multiplying the average weekly hours by the number of weeks.
Calculate your salary. Multiply your working hours by your hourly wage.
- For example, if you earn 90,000 VND per hour, multiply 2,470 by 90,000 VND. Your annual salary would be 222,300,000 VND.
Additional Compensation
Include bonuses. Add bonuses, commissions, or any other incentives you receive to your annual salary. Many hourly positions include incentives as part of the hourly wage. For instance, you might receive bonuses based on performance, leadership, or tenure (length of time in the role).
- Some employers offer annual holiday bonuses to all employees. Using the example from Part 1, imagine you receive a 4,000,000 VND bonus each year. Your calculation would be: 187,200,000 VND + 4,000,000 VND = 191,200,000 VND.
- If you earn commissions or variable bonuses, track these amounts over a year to include them in your salary. For example, imagine you receive a 1,000,000 VND bonus each time you hit a sales target. If you earn this bonus 12 times a year, multiply 1,000,000 VND by 12, resulting in 12,000,000 VND. Add this to 191,200,000 VND for a final total of 203,200,000 VND.
Deduct allowances and expenses. If you pay for medical expenses or contribute to a 401(k) in the United States, subtract these amounts to determine your "take-home pay."
- These amounts are still part of your income but represent money that doesn’t increase your purchasing power.
- Check your pay stub to see the monthly deductions for these expenses. Multiply the monthly amount by 12 to get the annual figure, then subtract it from your yearly income.
- For example, if medical expenses cost 3,000,000 VND per month, you’ll spend 3,000,000 VND x 12 = 36,000,000 VND annually. Subtract this from your annual salary.
Determine your income tax obligations. You’ll know whether your salary is pre-tax or post-tax. In Vietnam, to understand your income tax liability, you need to refer to the Personal Income Tax Law and the progressive tax brackets.
- In the United States, check which federal tax bracket your income falls into to determine your federal income tax rate. Your annual income will dictate your tax liability. Online tax bracket calculators can help you figure this out if you’re unsure of your bracket.
- In the U.S., state taxes depend on where you live. Many states don’t impose income tax. For those that do, the rate is typically around 5-6%. You can find your state’s income tax rate online.
- To calculate post-tax income in the U.S., subtract your tax rate from 100%. For example, if you’re in the 20% tax bracket, you keep 80% of your income.
- Convert the tax rate percentage to a decimal by moving the decimal point two places to the left. For instance, if you keep 80%, the decimal equivalent is 0.80 (or 0.8).
- Multiply your monthly income by this decimal to find your post-tax income in the U.S. You can calculate this for either monthly or annual earnings.
- If your U.S. salary is $2,800 and you’re in the 30% tax bracket, your decimal is 0.7. Multiply $2,800 by 0.7 to get $1,960 per month. This is your post-tax income in the U.S.
Tips
- Under the U.S. Fair Labor Standards Act, hourly employees must be paid for standby time. This is when the employer requires the employee to be present, even if there’s no work to do. You’re also paid for on-call hours when you must remain at the workplace and be ready to act. Additionally, you’re compensated for working during breaks or meal times. Breaks are usually less than 20 minutes; meal times are paid if you’re required to work during them.
- You can reverse the calculation to determine your hourly wage from your annual income. Divide your total annual earnings by the number of hours worked. For full-time work, this is typically 2080 hours (52 weeks x 40 hours). For example, someone earning 200,000,000 VND annually would have an hourly wage of 96,000 VND when dividing their salary by 2080.
- If you’re paid for vacation or sick leave and didn’t work for several weeks, don’t adjust the number of weeks you’re paid for (it remains 52 weeks). If you take unpaid leave for travel, subtract those weeks from 52.
