How to Read Your Results
Use the monthly total as a simple estimate of regular household spending.
Use the annual total to plan for a full year, but remember it does not include inflation or one-off costs unless you add them.
Compare cost per person when looking at different household sizes.
Check housing share to see whether one category is taking a large portion of the budget.
Assumptions & Important Notes
- Each example assumes monthly costs stay broadly similar throughout the year.
- Only recurring costs entered in the calculator are counted.
- Per-person cost is an average, not a measure of each family member's actual spending.
- The examples are educational estimates, not a full personal budget plan.

Frequently Asked Questions
What do these family cost of living examples show?
They show how different household sizes and spending patterns affect monthly total cost, annual cost, per-person cost, and housing share.
Why do some larger families have a lower cost per person?
Some costs, especially housing and utilities, are shared across more people, so the average per person can fall even if the total rises.
Can I use these examples as my actual budget?
No. They are worked examples to show the calculation method. Your real budget depends on your own expenses and circumstances.
Which example is most realistic?
That depends on your household size, housing costs, transport needs, and childcare situation. Use the closest example as a starting point.
Why does housing share change across examples?
Housing share changes because it depends on housing cost relative to the overall monthly total, not just on housing alone.
