Rental Yield Calculator South Africa 2026
Gross yield, net yield, monthly cash flow and cap rate — with full expense breakdown
Calculator Features
How to Use This Calculator
Enter your property value and expected monthly rent. Then fill in your monthly expenses: rates and taxes, body corporate levy (for sectional title), insurance, a maintenance allowance, and your management fee if you use a rental agent. The calculator shows gross yield, net yield, monthly cash flow, cap rate, and annual return.
Gross Yield vs Net Yield vs Cap Rate
Gross yield
Gross yield ignores all expenses. It is useful for a quick comparison between properties but tells you nothing about actual profitability.
Net yield
Net Income = Annual Rent − (Rates + Levy + Insurance + Maintenance + Management Fee)
Net yield accounts for operating expenses but not bond repayments. This is the standard metric for comparing investment properties.
Cap rate
The capitalisation rate equals the net yield when calculated without financing. It represents the return you would earn if you bought the property in cash. A higher cap rate indicates a better income-generating asset relative to its value.
What is a Good Rental Yield in South Africa?
South African rental yields vary significantly by area, property type, and price bracket:
- 8%+ net yield — Excellent. Strong cash flow, viable as a standalone investment.
- 6–8% net yield — Good. Positive cash flow, reasonable return given SA property appreciation.
- 4–6% net yield — Below average. Negative cash flow likely after bond repayments. Requires capital appreciation to justify.
- Below 4% net yield — Poor income return. Speculative appreciation play only.
In 2026, prime lending rate is 10.25%. A property with a net yield below 6% will be cash-flow negative if financed with a bond, meaning you top up monthly from other income.
Worked Example
Andile owns a R1 500 000 two-bedroom flat in Rosebank, Johannesburg. He rents it for R12 000/month. Monthly expenses: rates R1 500, levy R2 500, insurance R500, maintenance R500, management fee R960 (8% of rent).
Gross yield: (R144 000 ÷ R1 500 000) × 100 = 9.6%
Total monthly expenses: R5 960
Net monthly income: R12 000 − R5 960 = R6 040
Annual net income: R72 480
Net yield: (R72 480 ÷ R1 500 000) × 100 = 4.83%
If Andile self-manages (removes R960 fee), net yield rises to 5.60%. Still cash-flow negative after a bond repayment on R1 200 000 at 10.25% = ~R11 800/month.
Frequently Asked Questions
What is a typical rental yield in South Africa in 2026?
Average gross rental yields in South Africa in 2026 range from 7%–10% depending on area and property type. Net yields are typically 2–4 percentage points lower after expenses. Smaller, more affordable properties (R500 000–R1 000 000) tend to show higher yields. High-value properties in premium suburbs typically yield lower percentages but offer capital appreciation upside.
Does this calculator include bond repayments?
No. Yield and cap rate calculations use the property value (not loan amount) and exclude bond repayments. This allows for a fair comparison between properties regardless of financing. To see cash flow after bond repayments, use the Rental Cash Flow Calculator.
What vacancy rate should I factor into my rental yield?
A conservative approach is to assume 1 month vacancy per year (8.3% vacancy rate), meaning your annual rent effectively equals 11 months × monthly rent. In strong rental markets (Cape Town CBD, Sandton, Umhlanga), vacancy may be very low. In softer markets, plan for 1–2 months per year. Include this in your maintenance allowance or reduce the monthly rent figure to reflect realistic annual income.
How does the management fee affect my yield?
South African rental agencies typically charge 8–10% of monthly rent as a management fee, plus VAT in some cases. On a R12 000 rent at 10%, that is R1 200/month or R14 400/year — reducing net yield by roughly 0.96% on a R1 500 000 property. Self-management saves this cost but requires significant time and involvement.
Is rental income taxable in South Africa?
Yes. Rental income is taxable as ordinary income at your marginal tax rate. However, you can deduct expenses: bond interest (not capital repayment), rates, levy, insurance, maintenance, management fees, municipal charges, and depreciation on furniture. Keeping detailed records is essential. Declare all rental income on your annual ITR12 return. Consider consulting a tax professional if rental income is significant.
