Overtime Calculator South Africa

How Overtime is Calculated in South Africa

Overtime pay in South Africa is governed by Section 10 of the Basic Conditions of Employment Act (BCEA). The law sets minimum rates that employers must pay for hours worked beyond the ordinary working week — and separate rates for work on Sundays and public holidays under Section 16.

The BCEA protections apply to employees earning below the earnings threshold of R269,600.90 per year (R22,466.74 per month), effective 1 May 2026. Employees above this threshold have their overtime terms governed by their individual employment contracts rather than the BCEA minimum.

The BCEA Overtime Rates

Step-by-Step Manual Calculation Example

An employee earns R15,000 gross per month, works a standard 45-hour week and in a given week works 6 hours of weekday overtime and 4 hours on a Sunday.

Step 1 — Calculate the normal hourly rate

Step 2 — Calculate weekday overtime pay

Step 3 — Calculate Sunday pay

Step 4 — Total overtime pay

This overtime pay is taxed as ordinary income via PAYE, not at any special rate — use our PAYE calculator to see how it affects your monthly take-home pay.

BCEA Overtime Limits You Need to Know

The BCEA does not just set the rate — it also caps how much overtime you can be required to work. See our work hours calculator for the full breakdown of BCEA ordinary and maximum daily hours. These limits protect employees from excessive working hours:

• Maximum overtime: 10 hours per week
• Maximum per day: 3 hours of overtime in any single day
• Maximum daily total: 12 hours in any one day (including normal and overtime hours)
• Overtime by agreement only: An employer cannot unilaterally require overtime — it must be agreed upon between employer and employee
• Collective agreement exception: the weekly cap can rise to 15 hours, but only for up to 2 months in any 12-month period — a limited exception, not the default
• 4-month averaging: By written agreement, overtime can be averaged over a period not exceeding 4 months

Time Off In Lieu of Overtime Pay (TOIL)

Instead of paying overtime at the applicable rate, an employer and employee can agree in writing to grant paid time off — commonly called TOIL (Time Off In Lieu). The BCEA sets a minimum for this arrangement:

• For weekday overtime at 1.5×: at least 1.5 hours of paid time off for each overtime hour worked
• For Sunday/public holiday overtime at 2×: at least 2 hours of paid time off for each hour worked

The TOIL must be taken within one month of the overtime being worked. This arrangement must be agreed to in writing and cannot be imposed by the employer.

The BCEA Earnings Threshold — Does Overtime Apply to You?

The BCEA earnings threshold was updated to R269,600.90 per year (R22,466.74 per month) with effect from 1 May 2026. Employees earning below this threshold are automatically entitled to all BCEA overtime protections. Employees earning above this threshold have their overtime terms governed by their individual employment contracts.

If you earn above the threshold but your contract states that overtime is payable at BCEA rates — that contract term is valid and your employer is bound by it. If your contract is silent on overtime, your employer is not legally required under the BCEA to pay you overtime at 1.5× or 2× rates. Negotiating these terms before signing your contract is critical for higher-earning employees.

Overtime on Sundays and Public Holidays — Different Rates Apply

Standard overtime (1.5x or 2x for weekday/Saturday work beyond ordinary hours) is different from work performed on a Sunday or public holiday, which the BCEA treats as a separate category regardless of whether it falls within your normal weekly hours. Under Section 16, an employee who occasionally works on a Sunday must be paid double their normal wage for that day's work; if Sunday work is a regular part of your role (built into your ordinary working days), the rate drops to 1.5x instead. Public holiday work follows a similar principle under Section 18 — you're entitled to double pay for hours worked on a public holiday that falls on a day you would not normally have worked, or your ordinary daily wage plus the amount earned for the hours actually worked if it falls on a day you would have worked anyway.

Can Your Employer Force You to Work Overtime?

No. Overtime must be agreed to, either in your original employment contract or at the time it's requested. An employer cannot unilaterally instruct you to work overtime without your consent, and refusing reasonable overtime requests is not, on its own, grounds for disciplinary action unless your contract specifically requires it (common in roles like security or healthcare with rostered shift patterns). That said, once agreed to, whether via a standing clause in your contract or a one-off request you accept, overtime becomes enforceable like any other term of employment, and the BCEA's 10-hour weekly cap still applies regardless of what you agreed to.

Does Overtime Pay Affect Your UIF Contributions?

Yes. Overtime pay counts as remuneration for UIF purposes, so it forms part of the amount your 1% employee contribution, and your employer's matching 1%, is calculated on. This only matters up to the UIF earnings ceiling of R17,712 per month — if your total remuneration for the month, overtime included, pushes you over that cap, UIF is still deducted only on the first R17,712, not on the full amount.
