How to Read Your Results
Total monthly cost shows your estimated regular living expenses for one month.
Total annual cost is the monthly figure multiplied by 12, so it is best treated as a broad estimate.
Monthly balance shows whether income covers regular expenses and how much may remain.
Expense share of income helps show how much of take-home pay is already committed before savings or irregular costs.
Assumptions & Important Notes
- Each example assumes monthly expenses stay broadly similar over the year.
- Examples use net income rather than gross income.
- Irregular annual costs are not included unless added to other monthly expenses.
