Understanding the Salary Requirement
South African banks use the debt-to-income (DTI) ratio to determine how much you can borrow. Under the NCA, lenders ensure your total monthly debt obligations (including the new home loan) do not exceed 28-30% of your gross monthly income.
For this property at R 1 400 000, your total monthly commitment is R 12 369 (bond R 12 369 + debts R 0), meaning you need a minimum gross income of R 41 229/month.

How to Use This Calculator
Enter the property price you are considering and your expected deposit percentage (10% is typical in SA). Set the interest rate — most banks lend at prime (10.25%) — and choose your bond term. If you have existing debts (car finance, credit cards, personal loans), enter the total monthly amount. The calculator reverses the affordability equation to tell you the minimum gross monthly salary you need to qualify.
Use the Income Scenarios tab to see how the salary requirement changes across different property prices.
The Salary Calculation Formula
South African banks use the debt-to-income (DTI) ratio mandated by the National Credit Act:
Where:
- Monthly Bond Payment = standard PMT calculation on the loan amount
- Other Debts = all monthly debt commitments (car, credit cards, personal loans)
- DTI Ratio = 28–30% is the NCA guideline; some lenders allow up to 33%
Most SA banks use 30% as the maximum DTI, meaning no more than 30% of your gross monthly income should go to debt repayments. Nedbank is slightly more conservative at 28%.
Worked Example
Sipho wants to buy a R1,400,000 home in Pretoria. He has a 10% deposit (R140,000), so he needs a bond of R1,260,000.
At the current prime rate of 10.25% over 20 years, his monthly bond repayment would be approximately R12,437.
He also pays R3,500/month for a car loan. His total monthly debt would be R15,937.
Using the 30% DTI rule: R15,937 ÷ 0.30 = R53,123/month gross salary (approximately R637,480/year).
If Sipho and his partner apply jointly, they need a combined household income of R53,123/month. In a 60/40 split, Sipho would need R31,874/month and his partner R21,249/month.
Frequently Asked Questions
What salary do I need to buy a R1 million house in South Africa?
For a R1,000,000 property with a 10% deposit (R100,000 bond of R900,000) at 10.25% over 20 years, your monthly repayment is approximately R8,884. Using the 30% DTI rule, you need a minimum gross monthly salary of about R29,613 — assuming no other debts.
What is the DTI ratio and why does it matter?
The debt-to-income (DTI) ratio measures what percentage of your gross monthly income goes to debt repayments. Under the National Credit Act (NCA), South African lenders must ensure borrowers can afford their total debt obligations. Most banks cap this at 30% for home loans.
For example, if you earn R40,000/month gross, the maximum total debt (including bond, car, credit cards) you can service is R12,000/month.
Can I use a joint income to qualify for a bigger bond?
Yes. South African banks allow joint home loan applications where the combined income of two applicants is used to calculate affordability. This significantly increases the property price you can qualify for. Note that both applicants are jointly and severally liable for the full bond amount.
Do existing debts affect how much house I can afford?
Absolutely. Existing monthly debt commitments are added to your proposed bond repayment when banks calculate your DTI ratio. A R3,000/month car payment effectively reduces the bond amount you qualify for by approximately R300,000. Paying off debts before applying for a home loan can significantly increase your buying power.
What if my salary is slightly below the required amount?
If you are close but not quite meeting the salary requirement, consider these strategies: increase your deposit to reduce the bond amount, extend the term to 25 or 30 years (lower monthly payment but more interest), pay off existing debts first, or apply with a co-applicant. If your household income is between R3,501 and R22,000/month, the FLISP subsidy can also supplement your deposit.
