How this calculator works

The calculator totals the standard categories plus any custom rows you add, then compares them with monthly take-home income. It also highlights the proportions going to essentials, debt/lifestyle and savings.

How to use it

  1. Enter monthly take-home income.
  2. Add your main essential household costs.
  3. Add debt payments, lifestyle spending and planned savings.
  4. Add custom lines for costs specific to your household.
  5. Review your monthly margin and category proportions.

Assumptions and limitations

Use actual bank statements where possible. Annual and irregular costs are best converted to monthly equivalents so they are not forgotten.
