Short answer
Cover housing, food, transport, insurance, and minimum debt payments before deciding how much extra to pay. Keep a small emergency buffer so every surprise does not become new debt.
Protect the essentials first
Cover housing, food, transport, insurance, and minimum debt payments before deciding how much extra to pay. Keep a small emergency buffer so every surprise does not become new debt.
Choose an extra-payment strategy
Compare the interest rate, balance, and motivation of each debt. Direct extra money consistently, then update the budget as a balance falls.
Worked South African example
For example, start with R28,000 after-tax income, add your essential costs and recurring payments, and use the remaining amount to plan savings or debt reduction.
