[10] A tandem axle is defined as two or more consecutive axles whose centers are spaced more than 40 inches (102 cm) but not more than 96 inches (244 cm) apart. Net pay is a worker’s total take-home pay, or what’s left after payroll taxes and deductions are taken out. If employees are paid every two weeks, there are 26 pay periods. The formula is necessary to prevent heavy vehicles from damaging roads and bridges. These weigh stations are run by state DOTs, and CMV weight and size enforcement is overseen by the FHWA. Remember that, typically, overtime is 1.5 times the employee’s hourly rate. When standing upright, a person's weight is concentrated at the bottom of their feet, funneling all of their weight into a small area. Table 1 illustrates the formula. Table 4 illustrates the formula. If the employee had also earned a $50 commission on top of that, their gross pay for the week would be $1,203,85. We provide third-party links as a convenience and for informational purposes only. [1], Penalties for violating weight limits vary between states (bridge formula weight violations are treated as gross weight violations), as the states are responsible for enforcement and collection of fines. Readers should verify statements before relying on them. Some common deductions include FICA payroll taxes, income tax withholdings, health insurance, and retirement contributions. If the employee works 40 hours, they’ve earned $600. Without it, the bridge formula would allow an actual weight of only 66,000 pounds (30,000 kg) to 67,500 pounds (30,600 kg) on tandems spaced 36 feet (11 m) to 38 feet (11.6 m) apart; compared to 68,000 pounds (31,000 kg) with the exception. No assurance is given that the information is comprehensive in its coverage or that it is suitable in dealing with a customer’s particular situation. [16][17] Driving a truck over a bridge that is too weak to support it usually does not result in an immediate collapse. Step 1: Start with the employee’s gross pay. [24], There is one exception to the formula: two consecutive sets of tandem axles may carry 34,000 pounds (15,000 kg) each if the overall distance between the first and last axles of these tandems is 36 feet (11 m) or more. This exception was specifically requested by the American Trucking Associations to allow tank trucks to reach the maximum legal gross weight without violating the bridge formula law. Intuit does not endorse or approve these products and services, or the opinions of these corporations or organizations or individuals. Offer valid for a limited time only, while stocks last. This difference in weight distribution would allow a person to cross an area of ice while crawling that might otherwise collapse under their body weight while standing up. Gross pay and net pay sound interchangeable, but as you can see from these examples, they’re anything but. Highways, and state highways known as the National Network (NN). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer. Gross pay includes any overtime, bonuses or reimbursements from an employer on top of regular hourly or salary pay. And if employees are paid once a month, there are 12 pay periods. [23], Some states require overweight trucks to offload enough cargo to comply with the limits. The employee’s yearly salary is $60,000. CMVs are most often tractor-trailers or buses, but the formula is of most interest to truck drivers due to the heavy loads their vehicles often carry. For instance, California employees have additional state withholdings for State Disability Insurance (SDI) and Personal Income Tax (PIT). [11], In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). [15], Some smaller bridges have a weight limit (or gross weight load rating) indicated by a posted sign (hence the reference to a "posted bridge"). The formula is part … The gross profit margin formula.

CMVs are restricted by gross weight (total weight of vehicle and cargo), and by axle weight (i.e., the weight carried by each tire). The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing. As time passed, truck weight limits focused primarily on gross weight limits (which had no prescribed limits on length). Weekly: $60,000 / 52 = $1,153.85 per pay period, Every two weeks: $60,000 / 26 = $2,307.69 per pay period, Semi-monthly: $60,000 / 24 = $2,500 per pay period, Monthly: $60,000 / 12 = $5,000 per pay period. [1][6], A division of the DOT, the Federal Motor Carrier Safety Administration (FMCSA), regulates safety for the U.S. trucking industry. Here’s how an employee’s gross pay would be impacted, based on the number of pay periods in the year. Here’s how that gross pay formula would look, using a one-week pay period. [8], CMVs are defined by the FMCSA as vehicles engaged in interstate commerce that are used to transport passengers or property: vehicles with a gross vehicle weight of 10,001 pounds (4,536 kg) or more; those designed or used to transport more than 8 passengers (including the driver) for compensation; vehicles designed or used to transport more than 15 passengers (including the driver) without compensation; or those used to transport hazardous materials in quantities requiring the vehicle to be marked or placarded under hazardous materials regulations. To be eligible, the vehicle's operator must prove the weight of the APU with written certification, or—by demonstration or certification—that the idle reduction technology is fully functional at all times. Most of these cracks are discovered during mandated inspections of bridges. Start by subtracting any pre-tax deductions offered by the business, such as health insurance premiums or retirement contributions. For example, say a salaried employee makes $60,000 a year, and the company has one-week pay periods. Income is defined as all employee compensation plus investment profits. It was the only way tank truck operators could reach 80,000 pounds without adding axles to their fleets of trailers already in operation. In this case, the employee worked two overtime hours and earned a $50 commission. This week, the total comes out to $59. Now she has $650,000 that can be used to pay for other bills like rent and utilities. Employees may also have wages garnished or live in another state and pay additional taxes because of it. Simply divide the $650,000 GP that we already computed by the $1,000,000 of total sales. The bridge may develop cracks, which over time can weaken the bridge and cause it to collapse. For a prospective real estate investor, a lower GRM represents a better opportunity. Step 2: This is where the deductions begin. About 1,500 bridges collapsed between 1966 and 2007, and most of those were the result of soil erosion around bridge supports. Step 3: Add in any additional earnings for the pay period, including commissions, bonuses, or even overtime pay if the salaried employee is nonexempt. "[10], The August 2007 collapse of the Interstate 35W Mississippi River bridge in Minneapolis brought renewed attention to the issue of truck weights and their relation to bridge stress. If these combinations are found to be satisfactory, then all of the other axle groups on this type of vehicle will usually be satisfactory. [1] FHWA regulation §658.17 states: "The maximum gross vehicle weight shall be 80,000 pounds (36,000 kg) except where lower gross vehicle weight is dictated by the bridge formula. With so many deductions to consider, don’t be surprised if two employees with the same gross wages have different net pay. Table 6 illustrates the formula. Florida also allows for a load to be shifted (e.g., moved from the front towards the rear of the vehicle) for the vehicle to comply with axle weight limits, without penalty. [2], In the late 1950s, the American Association of State Highway and Transportation Officials (AASHTO) conducted a series of extensive field tests of roads and bridges to determine how traffic contributed to the deterioration of pavement materials. The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing. [25], A CMV may exceed the bridge formula limits (or gross weight and its axle weight limits) by up to 550 pounds (249 kg) if the vehicle is equipped with an auxiliary power unit (APU) or idle reduction technology. For an overweight truck to comply with the formula, more axles must be added, the distance between axles must be increased, or weight must be removed. For example, if an employer offers you a sales position with a base salary of $50,000 plus a bonus of $2,500 for every $25,000 in sales, the total you earn would be your gross pay. The federal weight limits for CMVs are 80,000 pounds (36,000 kg) for gross weight (unless the bridge formula dictates a lower limit), 34,000 pounds (15,000 kg) for a tandem axle, and 20,000 pounds (9,100 kg) for a single axle. TTI HS-20 allowed shorter trucks to have higher weight limits than Formula B. Divide $60,000 by 52 weeks for a total of $1,153.85 per pay period. This exception was sought by the American Trucking Associations so trucking companies could use 40-foot (12.2 m) trailers and weigh 80,000 pounds (36,000 kg). The one exception to the formula allows a standard five-axle semi-truck configuration to weigh the maximum legal gross weight. Determining gross profit margin is a simple calculation with the option to calculate margin using a dollar amount or a percentage. [28], In 1987, the U.S. Congress passed the Surface Transportation and Uniform Relocation Assistance Act, requesting the Transportation Research Board (TRB) to conduct a study to develop alternatives to Formula B. To calculate a salaried employee’s gross pay for a single pay period, divide their annual salary by the number of pay periods in the year. Gross National Income (GNI) is a measurement of a country's income. Accordingly, the information provided should not be relied upon as a substitute for independent research. [28] TTI HS-20 also failed to address the problem of multiple-span bridges. [12] In November 2008, the National Transportation Safety Board determined there had been several reasons for the bridge's collapse, including (but not limited to): faulty gusset plates, inadequate inspections, and the extra weight of heavy construction equipment combined with the weight of rush hour traffic. You calculate gross wages differently for salaried and hourly employees. But if you have payroll service, most of these calculations are done automatically. Gross profit percentage is the formula which is used by the management, investors and financial analysts to know the financial health and profitability of the company after accounting for the cost of sales and is calculated by dividing the gross profit of the company by its net sales. Step 1: Multiply the hourly rate by the number of hours worked, up to 40 hours per week. [4] Although this means that any two axles must comply with the formula, experience has shown that axles 1 through 3, 1 through 5, and 2 through 5 are critical and must be checked. The formula effectively lowers the legal weight limit for shorter trucks, preventing them from causing premature deterioration of bridges and highway infrastructure. The employee’s overtime pay rate is $22.50, so they earned $45 plus their commission. Step 1: Multiply the hourly rate by the number of hours worked, up to 40 hours per week. Let’s say the employee makes $15 per hour. Monica can also compute this ratio in a percentage using the gross profit margin formula. When lying down, a person's weight is distributed over a much larger area. Let’s say an employee asks you to deduct 6% of their gross pay each week to put toward their 401(k). [14], As of 2007, federal estimates suggest truck traffic increased 216% since 1970, shortly before the federal gross weight limit for trucks was increased by 30,000 pounds (14,000 kg). Compliance with the law is checked when vehicles pass through a weigh station, often located at the borders between states or on the outskirts of major cities, where the vehicle may be weighed and measured. In Florida, any vehicle that exceeds the limits by more than 6,000 pounds (2,700 kg) is required to be unloaded until the vehicle is in compliance. It’s their cumulative earnings amount, meaning it includes any overtime pay, bonuses, and payroll advances the worker has earned that pay period. It includes all the income earned by a country's residents, businesses, and earnings from foreign sources. For example, a truck with a legal gross limit of 20,000 pounds (9,100 kg) that violates the limit by 5,000 pounds (2,300 kg) would pay a fine of $500, while a truck with a legal gross limit of 60,000 pounds (27,000 kg) that violates the limit by 5,000 pounds would pay a fine of $250. Gross domestic product also includes services and government-produced value. If the employee works 40 hours, they’ve earned $600. Provided the truck remains on the NN, it is not subject to state limits. Intuit accepts no responsibility for the accuracy, legality, or content on these sites.
