The law is per hour, not per day
South African minimum wage is expressed per hour — R30.23 from 1 March 2026 — so any legal day rate is just the hours multiplied by R30.23. A 9-hour day (typical for a 45-hour, five-day week) is R272.07; an 8-hour day is R241.84; a half-day of 4.5 hours is R136.04. Agreeing a flat 'day rate' is fine, as long as it never works out to less than R30.23 for each hour the worker actually does.
The 4-hour minimum sets the floor
Under the BCEA, a worker who reports for work must be paid for at least 4 hours even if sent home early. At R30.23 that's a hard floor of R120.92 for any day worked. So even a short day — fetching, a quick clean, a few hours' ironing — cannot be paid less than R120.92 if the worker came in.
From minimum to fair
The minimum is the floor, not the going rate. A full day's domestic work for a five-day-a-week worker commonly pays somewhere between about R250 and R350 a day depending on the suburb, the duties (cleaning vs. childcare vs. cooking), and the worker's experience — and many households pay more for trusted, long-serving help. Use the minimum as the line you cannot cross, then pay a fair rate above it.
Day rate and the monthly equivalent
If you pay a day rate, it should reconcile with a fair monthly figure. A five-day worker on R272.07 a day works out to roughly R5 894 a month (about 195 hours at R30.23). Whatever the headline rate, remember the day rate is basic pay only — you must still handle UIF (1% + 1%, up to R177.12 each), paid leave and the right notice on top.
