Paying off debt is part maths, part motivation. These three tools cover both — a payoff strategy, an affordability check and a budgeting framework — using South African figures and the National Credit Act rules lenders work under.
How to use these tools
- Debt snowball — list each debt with its balance, rate and minimum, add whatever extra you can afford, and see your debt-free date plus the interest saved. It compares the snowball (smallest balance first, for momentum) with the avalanche (highest rate first, for lowest cost).
- Debt-to-income ratio — enter your income and monthly debt repayments to see the same affordability ratio lenders use under the NCA.
- 50/30/20 budget — split your take-home pay into needs, wants and savings, and compare the guideline with what you actually spend.
What the figures mean
A debt-to-income ratio under about 36% is generally considered healthy by South African lenders; higher ratios make new credit harder to get and leave less room to absorb a shock. The snowball's “interest saved” figure is the gap between paying minimums forever and following the plan — usually thousands of rand and many months off your timeline.
Common mistakes to avoid
- Paying only minimums on high-interest debt while the balance barely moves.
- Taking new credit to consolidate without changing the spending that created the debt.
- Budgeting without tracking — the 50/30/20 split only helps if you compare it against reality.
If repayments have become unmanageable, the National Credit Regulator oversees registered debt counsellors and your rights under the NCA.
