In this article, we explore what gross salary is, what deductions are taken from it, and how to calculate your earnings correctly.

What is gross salary?

Gross salary is the total amount of money an employee earns before any deductions are taken. These deductions may include taxes, social security contributions, retirement contributions, health insurance premiums, etc.

For example, suppose an employee earns $50,000 annually and has no deductions taken out. In that case, their gross salary would also be $50,000. However, if the employee has deductions taken out, their gross salary would be higher than their net salary, which is the amount of money they take home.

It's worth noting that gross salary can also refer to an employee's total earnings, including any bonuses, commissions, or overtime pay they may receive. In this case, gross salary is still calculated before any deductions are taken out.

Common allowances on your payslip

A personal allowance is a tax-free income that you can receive. If you're a UK-based employee under 65, your employer may deduct this allowance from your salary before calculating your income tax. There are different types of personal allowances available.

  • Tax-free personal allowance: The tax-free personal allowance for the 2019/2020 financial year was up to £12,500, but your income level may affect this amount. If you earn over £100,000 per year, your allowance reduces by £1 for every £2 earned above £100,000.

  • Married couple allowance: Married couples and civil partners are eligible for a married couple's allowance, which allows them to combine their taxes as if they were one person. They can split the allowance or have one person claim it entirely. This year (2019/2020), the allowance is £8,915, with a relief cap of 10% of the allowance.

Why does gross salary matter?

Understanding gross salary is crucial because it affects several aspects of your financial life. Here are some reasons why gross salary matters:

  1. Negotiating Salary: Knowing your gross salary is essential when negotiating a salary. This allows you to make informed decisions about whether the offer is fair and whether you're compensated for your skills and experience.

  2. Understanding Benefits: Many employee benefits, such as health insurance, retirement plans, and life insurance, are calculated based on an employee's gross salary. Knowing your gross salary can help you determine your eligible benefits and how much they'll cost.

  3. Tax Implications: Gross salary also plays a significant role in determining your tax liability. Since taxes are calculated based on your gross salary, knowing this figure can help you plan your taxes better and avoid any unpleasant surprises come tax season.

  4. Budgeting: Knowing your gross salary is crucial when it comes to budgeting. This figure allows you to determine how much money you'll have each month, which can help you create a realistic budget and avoid overspending.

Gross salary vs. net salary

You may see two numbers when you receive your gross and net salary statement. Understanding the difference between the two is essential to avoid confusion about your earnings.

Gross salary is the amount your employer pays you based on your agreed-upon salary. It is the highest number you will see on your salary statement. This number does not consider any taxes or other deductions from your pay check. Your gross salary is the starting point for calculating your earnings before making any deductions.

On the other hand, net salary is what you take home after all contributions and taxes are deducted from your gross salary. It is the actual amount of money you receive in your bank account. It is the amount you can use to pay your bills, buy groceries, or save for a vacation. Your net salary is calculated by subtracting all mandatory deductions from your gross pay.

Mandatory deductions include federal and state taxes, social security contributions, health insurance premiums, retirement plan contributions, and other deductions required by law. These deductions are taken from your gross pay to cover your citizen and employee obligations.

For example, your gross salary is £1,200 per pay period. If £350 is taken out of your paycheck for taxes, social security, health insurance, and retirement contributions, your net salary would be £850. This means that £350 is deducted from your gross salary to earn your net salary. The gap between your gross pay and net pay is the deductions.

Understanding the difference between gross and net salaries is crucial because it helps you plan your budget. Your gross salary may give you an idea of your earning potential, but your net salary is the amount of money you have available to use. You need to budget based on your net salary because that is the amount you will have to pay your bills, save for the future, and have fun.

Deductions from gross salary

Your employer will voluntarily and mandatorily deduct some money from your gross salary, lowering your net salary. Additionally, your choices regarding benefits or savings may also affect your salary. Here are some common deductions you may face in the UK.

Mandatory payroll deductions

In the UK, employers must withhold payroll taxes from employees' gross salaries before issuing paychecks. There are various tax regulations that employers must adhere to when deducting pay. Your employer cannot deduct money from your payment for legal reasons. Certain required tax deductions must be taken out of your gross pay. Examples of such mandatory tax deductions are:

  • Government income taxes
  • Student loan repayments
  • National insurance deductions

You cannot control the amount your employer deducts from your paycheck as an employee. However, you can view your payslip to stay informed about these deductions and where they go.

Your tax code is used to inform your employer about your tax exemptions. In the UK, most individuals with a single job or pension are assigned tax code 1150L. This code means you can earn up to a maximum of £12,500 in gross salary per year before you start paying taxes. Ensuring your tax code is accurate to prevent overpaying or underpaying taxes is crucial.

Once you reach this income threshold, HMRC will start deducting a percentage from any additional income you earn. The percentage deducted will vary based on your expected income for the year. The income tax system has different rates applied to taxable income in the previous four years.

  • Individuals who earn an income of £0 to £12,500 are exempted from paying any tax as it falls under the category of the personal allowance.

  • The standard tax rate is currently 20%, which applies to individuals earning between £12,500 and £50,000 annually, regardless of their citizenship status.

  • Individuals who earn between £50,001 and £150,000 are subject to a higher tax rate at 40%.

  • Individuals with a yearly income exceeding £150,000 must pay an extra 45% tax rate.

Voluntary payroll deductions

Employers may deduct optional payments from your pay cheque with your permission. These voluntary deductions can include common items such as health insurance or retirement contributions, which you'll see listed on your payslip.

  • Charitable contributions: Payroll giving, also called workplace giving, allows you to donate money to a charitable organization directly from your salary. The donation is made before taxes are deducted. Your employer must affiliate with an authorized payroll giving agency to arrange this.

  • Life insurance premiums: You can deduct a portion of each paycheck to contribute towards a life insurance fund. Your chosen beneficiaries will receive the payout from this fund after your death.

  • Health insurance premiums for vision, dental, and other medical coverage: The amount deducted from your salary for health insurance will vary depending on your employer's plan and provider. It is important to choose the plan that best fits your healthcare needs and your dependents' needs. Typically, health insurance covers the cost of prescriptions and visits to the doctor.

  • Certain retirement earnings: You can remove voluntary retirement deductions from your pay cheque. The 401(k) or 403(b) plans are not included in your gross income, while other plans such as a Roth IRA contribution are included in your gross income.

  • Employer-specific deductions: employers might inform employees about various other deductions apart from taxes, such as equipment and uniform costs that are essential for the job, union dues, and flexible savings accounts. Employees may be able to decline these deductions, but some employers consider them mandatory based on the employment contract. It's advisable to check with the HR team about any available options regarding payment.

How to calculate gross salary

To determine your gross salary, refer to your latest salary statement. Calculating gross salary differs based on whether you receive a salary or hourly wage.

Calculating gross income for salaried employees

To determine your gross salary as a salaried employee, follow these steps:

  • Determine your gross pay per period.
  • Determine the number of pay periods per year.
  • Multiply your gross pay by the pay periods in the year.

For example, if your gross monthly payment from your employer is £8,000, you will receive a total of £60,000 per year. This is because your employer pays you 12 times yearly, including £8,000.

Calculating gross income for hourly employees

To determine your gross income as an hourly employee, follow these steps:

  • Determine the number of hours you work every week.
  • Determine how much you earn in one hour.
  • Then multiply the hours you work by the amount you earn per hour.
  • To calculate your annual gross salary, multiply your weekly pay by 48.

For example, if you work 40 hours per week and make £20 per hour, your gross weekly salary is £800, your monthly salary is £3,200, and your gross annual pay is £41,600.

Calculating gross salary with overtime or commission

If you receive overtime pay or a regular commission/bonus each month, that amount will be added to your total monthly income (before taxes and other deductions). Please be aware that your work hours may include rest and meal breaks, on-call duty, waiting time, travel time, etc. As a result, your gross pay will also factor in your overtime compensation.

To calculate your gross hourly pay, follow these steps:

  • Calculate the total number of hours you worked during a specific period.
  • Calculate your hourly wage.
  • Calculate your total overtime, commission, and bonus for the past year, and then divide this amount by 12 to determine your monthly average.
  • Add this amount to your gross monthly pay.

If you receive a bonus on top of your regular salary, you will also be subjected to national insurance, income tax, and other related deductions on the extra income. For instance, if your regular salary is £40,000 and you receive a bonus of £5000, the HMRC will deduct all the necessary taxes from your gross salary of £45,000.

Calculating net salary

To calculate your net salary, whether you are a salaried or hourly employee, follow these steps:

  • Determine your month's gross salary.
  • List your deductions and the amounts.
  • Add up all deductions.
  • Subtract the total amount of deductions from your month's gross salary.

If you have a monthly payment of £4,000 and your total deductions are £500, your net income will be £3,500. You can use this amount to calculate hourly, daily, and weekly rates.

You may be able to negotiate a higher wage if you have special skills or qualifications, so it's advisable to check with your HR team about any available options you have when it comes to salary negotiations.

Overall, understanding your gross salary and how to calculate it can help you budget and plan for a successful financial future. The more you know about your income, the better prepared you will be to make intelligent decisions with your money.
