Working extra hours can make a meaningful difference to your monthly income, especially when household costs, transport and electricity bills keep rising. But how do you know whether your employer has calculated your overtime correctly?
In South Africa, overtime pay is mainly governed by the Basic Conditions of Employment Act (BCEA). The correct amount depends on your ordinary hourly wage, the number of overtime hours, whether you worked on a Sunday or public holiday, and any employment contract or collective agreement that applies.
What is overtime in South Africa?
Overtime is time worked outside your ordinary working hours by agreement between you and your employer. As a general rule, ordinary working hours may not exceed:
- 45 hours per week for employees working a five-day week or fewer.
- Nine hours per day if you work five days or fewer in a week.
- Eight hours per day if you work more than five days in a week.
You and your employer must generally agree to overtime. An employer should not simply expect unlimited unpaid extra work, although certain workplaces may have written agreements, bargaining council rules or sector-specific arrangements that affect scheduling.
The standard overtime rate is one-and-a-half times your ordinary hourly wage, commonly called time and a half.
Who qualifies for overtime pay?
Most employees covered by the BCEA qualify for overtime protections. However, the working-time provisions do not apply in exactly the same way to every worker.
Your position may require special consideration if you are:
- A senior managerial employee.
- A member of the South African National Defence Force, National Intelligence Agency or South African Secret Service.
- A sales employee who travels to customers and regulates their own working hours.
- An employee who works fewer than 24 hours in a month for an employer.
- An employee earning above the BCEA earnings threshold, depending on the applicable rules and contract.
The earnings threshold can change through government notices. Being above the threshold does not automatically mean your contract is irrelevant, but some BCEA working-time protections may not apply. Check your contract, workplace policy, bargaining council agreement or obtain advice from the Department of Employment and Labour.
Key takeaway: Before calculating overtime, first confirm that the BCEA overtime provisions apply to your role and that your extra hours were authorised or agreed.
The basic overtime pay formula
The standard formula is:
Overtime pay = Ordinary hourly wage × 1.5 × Overtime hours
For example, if your ordinary hourly wage is R60 and you work four overtime hours:
R60 × 1.5 × 4 = R360 overtime pay
This is the gross amount before PAYE, UIF and any other lawful deductions.
How to calculate your ordinary hourly wage
If you are paid hourly, your ordinary hourly wage is usually clear from your payslip or contract.
If you receive a weekly or monthly salary, use one of these calculations:
Weekly salary:
Weekly salary ÷ Ordinary weekly hours = Ordinary hourly wage
Monthly salary:
Monthly salary ÷ (Ordinary weekly hours × 52 ÷ 12) = Ordinary hourly wage
The monthly formula converts your annual working hours into an average monthly figure. Using 4.333 weeks per month is a simpler version:
Monthly salary ÷ 4.333 ÷ Ordinary weekly hours = Ordinary hourly wage
Your calculation should use the pay that represents your ordinary remuneration. Some allowances, bonuses, commission payments or benefits may be treated differently, so compare your approach with your employment contract and payroll policy.
Worked example 1: Monthly salary and ordinary overtime
Thandi earns R15,000 per month and works 45 ordinary hours per week. She works 10 approved overtime hours in one month.
Step 1: Calculate her ordinary hourly wage
R15,000 ÷ (45 × 52 ÷ 12)
R15,000 ÷ 195
= R76.92 per hour
Step 2: Apply the overtime rate
R76.92 × 1.5
= R115.38 per overtime hour
Step 3: Calculate the total overtime
R115.38 × 10 hours
= R1,153.80
Thandi’s gross pay for the month should therefore be approximately:
R15,000 + R1,153.80 = R16,153.80 before deductions
Payroll may produce a slightly different figure if the employer uses a contractual monthly-hours divisor. The important point is to check which divisor is stated in the contract or workplace policy.
Worked example 2: Hourly employee working overtime
Sipho earns R85 per hour and works six overtime hours during the week.
R85 × 1.5 × 6
= R765
His overtime earnings are R765 before deductions.
If he works overtime across several days, calculate each day separately and add the amounts together. Keep your own record of dates, start times, finish times and approved hours, particularly if your workplace uses a clock-in system.
Can overtime be paid as time off?
Instead of paying overtime in cash, an employer may provide paid time off if this is agreed and complies with the BCEA. The time off should generally reflect the value of the overtime worked.
For example, one hour worked at time and a half could be compensated with:
- 90 minutes of paid time off, or
- Payment of the overtime amount, depending on the arrangement.
An agreement may also provide for ordinary pay plus additional paid time off. Do not assume that “time off later” is lawful simply because a manager mentions it verbally. Ask how the arrangement will be recorded and when the time off can be taken.
Sunday overtime calculations
Sunday pay depends on whether Sunday is part of your ordinary working schedule.
If you do not ordinarily work on Sundays
You should generally receive at least double your ordinary wage for each Sunday hour worked.
Ordinary hourly wage × 2 × Sunday hours
Example:
- Ordinary hourly wage: R70
- Sunday hours: 5
R70 × 2 × 5 = R700
If Sunday is part of your ordinary working hours
You should generally receive at least one-and-a-half times your ordinary wage for the Sunday hours.
R70 × 1.5 × 5 = R525
There are exceptions and special arrangements, including situations where you work less than your ordinary hours on a Sunday. Your contract, collective agreement or bargaining council rules may provide more favourable terms.
Public holiday overtime pay
If you work on a public holiday, the minimum payment is usually at least double your ordinary daily wage, or the amount required under the applicable agreement.
If the public holiday falls on a day you would ordinarily work, you should generally receive the greater of:
- Your ordinary daily wage plus the public holiday payment required by law; or
- The statutory public holiday amount, depending on how the pay is structured.
If you do not ordinarily work on that public holiday but agree to work, the BCEA generally requires at least double pay for the work performed.
Because public holiday calculations can depend on whether the day was an ordinary working day, check the wording on your payslip and contract. A bargaining council agreement may set a higher rate.
What about night work?
Night work usually means work performed after 18:00 and before 06:00. The employer must inform employees about health and safety risks and may need to provide transport between the workplace and home where applicable.
Night work is not automatically the same as overtime. You may receive a night-work allowance, overtime pay, or both, depending on:
- Whether the hours exceed your ordinary hours.
- Your employment contract.
- A collective agreement or sectoral determination.
- Workplace policy.
For example, working from 22:00 to 02:00 may be ordinary scheduled work with a night allowance. If you work beyond your scheduled shift, the additional hours may qualify as overtime.
Is overtime taxable in South Africa?
Yes. Overtime is generally included in your gross employment income and may be subject to PAYE and UIF deductions. The overtime amount on your payslip will therefore not necessarily be the amount deposited into your bank account.
For example:
| Pay item | Amount |
|---|---|
| Basic monthly salary | R15,000 |
| Gross overtime | R1,153.80 |
| Gross pay before deductions | R16,153.80 |
| PAYE, UIF and other deductions | Depends on your circumstances |
| Net pay | Gross pay less deductions |
Your employer’s payroll system should calculate deductions using SARS rules. If you want to understand the result, read the earnings and deductions sections of your payslip. Our guide on how to read a South African payslip explains common payroll items and errors.
What if your employer does not pay overtime?
Start by checking the basics:
- Confirm that the extra hours were approved or required by your employer.
- Compare the overtime rate with your contract and workplace policy.
- Check whether Sunday or public holiday rules apply.
- Review your payslips and attendance records.
- Ask payroll or your manager for a written calculation.
- Keep copies of messages, rosters, clock-in records and payslips.
Use a simple spreadsheet to record each shift. Include the date, ordinary start and finish time, overtime hours, applicable rate and amount paid. A job-application tracker can be adapted for this type of record; see this simple spreadsheet tracking guide for a practical setup approach.
If the dispute is not resolved, you may contact the Department of Employment and Labour or consider referring the matter to the CCMA, where the dispute falls within its jurisdiction. Keep in mind that strict referral time limits may apply. This CCMA dispute guide explains the general process.
Common overtime calculation mistakes
Watch for these frequent errors:
- Using monthly salary as the hourly rate: Convert it into an hourly wage first.
- Paying ordinary time for overtime: Standard overtime is generally 1.5 times the ordinary hourly wage.
- Ignoring Sundays: Sunday work may attract a higher rate than weekday overtime.
- Treating public holidays as normal days: Public holiday work has separate protections.
- Calculating from net pay: Use gross ordinary remuneration before deductions.
- Assuming all extra time is overtime: Meal intervals and unpaid breaks may not count as working time.
- Relying only on verbal promises: Record approvals and payment arrangements in writing.
Final calculation checklist
Before accepting your overtime payment, ask:
- What is my ordinary hourly wage?
- How many hours were ordinary hours and how many were overtime?
- Were any hours worked on a Sunday or public holiday?
- Does my contract or bargaining council agreement provide a better rate?
- Was overtime paid at 1.5 times, double time or another agreed rate?
- Were lawful tax and UIF deductions applied?
- Do my payslip and attendance records match?
Calculating overtime pay in South Africa becomes much easier once you separate the ordinary hourly wage, applicable rate and number of hours. Keep reliable records, check your contract and raise discrepancies early—you have a much stronger position when your figures are clear and supported by evidence.
