How Much Home Loan Can You Qualify For?
Before you fall for a house, it helps to know what a bank will actually lend you. South African lenders work backwards from your income: they look at what you earn, what you already owe, and what is left to service a bond — then size the loan to fit. This calculator does the same in reverse, turning your income into an estimated maximum home loan and property price.
The 30% Guideline
Most South African banks want your monthly bond repayment to sit around 30% of your gross (before-tax) monthly income. On R35,000 a month, that is about R10,500 toward the bond. The calculator reverses that repayment into a loan amount using your interest rate and term — so a higher income, a lower rate, or a longer term all lift the figure. It is a guideline, not a guarantee: strong applicants sometimes stretch beyond 30%, while weaker credit profiles may be held below it.
Why Your Existing Debt Matters
The 30% rule is not the whole story. Under the National Credit Act, banks must run a full affordability assessment that weighs all your monthly commitments — car finance, credit cards, personal loans, store accounts. The more you already repay each month, the less is available for a bond. That is why this calculator subtracts your existing debt: clearing a car or a credit card before you apply can lift the home loan you qualify for by a surprising margin.
How Your Deposit Changes the Picture
A deposit does two things. It adds directly to the price you can afford — your loan plus your cash — and it lowers your loan-to-value ratio, which often earns a better interest rate. A better rate means a lower repayment for the same loan, which can nudge your qualifying amount up. Even a modest deposit can therefore buy you more house than the cash value alone suggests.
What Else the Bank Looks At
The figure here is a guideline based on income, debt, rate, term and deposit. The actual offer also depends on your credit score and history, the stability and source of your income (salaried applicants are assessed differently from the self-employed), the property valuation, and each bank's own lending appetite. Applying through more than one bank — directly or via a bond originator, which is free to you — regularly produces different offers, so it is worth comparing.
