What Is Disposable Income?
Disposable income is the amount left from your net income after essential living expenses have been paid. It is the money available to service debt, build savings or spend on non-essentials. In debt review, your disposable income is the figure used to calculate an affordable restructured monthly payment to creditors.
Key Points
- Disposable income is net income minus essential expenses.
- It is what is available for debt, savings and non-essentials.
- Debt review uses it to calculate affordable repayments.
- Accurate expense tracking is essential to get it right.
How to calculate it
Start with your net take-home pay. Subtract your essential living expenses — rent, utilities, food, transport, school fees, medical and insurance. The remainder is your disposable income.
Be realistic about essentials. Understating them inflates disposable income and leads to unaffordable debt plans; overstating them can hide a genuine affordability problem.
Why it matters for debt
Disposable income determines how much you can afford to pay toward debt each month. If your debt repayments exceed your disposable income, you are over-indebted. In debt review, the restructured payment is set at an affordable portion of your disposable income.
This is why an accurate budget is the foundation of any debt solution.
Building a buffer
Where possible, aim to keep a small portion of disposable income as an emergency buffer rather than committing every rand to debt. A buffer prevents unexpected costs from forcing you back into borrowing.
Even a modest buffer can make a significant difference over time.

How Do You Know If You Are Over-Indebted?
You may be over-indebted if your total monthly debt repayments plus essential living expenses exceed your net income, if you use one credit account to pay another, or if you regularly miss or juggle payments. Over-indebtedness means you cannot satisfy all your debt obligations in a timely manner. A financial assessment with a registered debt counsellor can confirm your position.

Your debt-to-income ratio is your total monthly debt repayments divided by your net monthly income, expressed as a percentage. For example, if you pay R6,000 toward debt on a net income of R20,000, your ratio is 30%. A lower ratio is healthier; a ratio above roughly 35–40% may signal over-indebtedness and warrants a financial assessment.
