Tips for Accurate Calculations #
Be realistic with your numbers
- Don’t underestimate expenses—round up if unsure
- Include only essentials, not your full lifestyle budget
- Review and update annually as your life changes
- Account for dependents (more people = higher expenses)
- Consider job security (less stable = longer runway)
