Rent Affordability Calculator South Africa
Find out how much rent you can afford in South Africa. Based on the 30% income rule, adjusted for your actual expenses. Compare your budget against average rents in Cape Town, Johannesburg, Durban, and Pretoria.
How to Use the Rent Affordability Calculator
Enter your monthly net income (take-home pay after tax). The calculator instantly shows three rent thresholds:
- Comfortable (25%): You'll have plenty left over for savings and unexpected costs
- Maximum (30%): The widely accepted guideline — most South African landlords use this rule
- Stretch (35%): Only feasible if your other expenses are very low
The Extended Calculator below lets you deduct actual expenses for a more accurate figure, and compares your budget against SA metro averages.

The 30% Rent Rule — Does It Still Work in South Africa?
The 30% guideline was established in the 1960s in the United States and has become a global benchmark. In South Africa's major metros, especially Cape Town, it can be hard to achieve on a typical salary. For example, the median formal salary in Cape Town is approximately R22,000/month net — giving a 30% budget of R6,600. However, an average Cape Town 1-bedroom costs R9,000+.
A more realistic approach is to use your disposable income after non-negotiable expenses rather than gross income. This is what the Extended Calculator above calculates.
Worked Example — R25,000 net salary in Johannesburg
Gross 30% rule: R7,500/month maximum rent
After deductions (transport R1,500 + food R2,500 + insurance R800 + medical R1,500 + debt R1,000 + savings R1,000 = R8,300):
Disposable income: R25,000 − R8,300 = R16,700
35% of disposable: R5,845 — more conservative and realistic
Conclusion: Comfortable JHB 1-bedroom at R7,000 works at R25k net income
