Calculate essential monthly costs
- Housing and basic utilities
- Basic groceries and transport
- Insurance, medical cover and essential medication
- Minimum debt repayments and support obligations
Choose the number of months
Three months is a reasonable next target for stable salaried work with limited dependants. Consider six months or more when income is variable, you support others, your job is specialised, or one income supports the household.
The right target is a range, not a moral score. Build it in stages so other urgent goals are not ignored.
Review after major changes
Moving out, buying a car, changing jobs or adding dependants can change both your essential costs and your risk.
A simple example
With essential costs of R11 000 a month, one month is R11 000, three months is R33 000 and six months is R66 000. Pick the stage that matches your risk and build towards it.
Common mistakes
- Using total lifestyle spending instead of essential costs
- Waiting for the perfect target before saving anything
- Never adjusting the target after a major life change
Quick checklist
- Total essential monthly costs
- Choose a one-, three- or six-month stage
- Subtract existing emergency savings
- Set a realistic monthly contribution
