Analysis...
You cannot fix a budget you cannot see. This calculator totals your expenses category by category — housing, food, transport, bills, fun — and shows each one's share of the whole, which is usually where the surprise lives.
How to use this calculator
- List your expenses, grouped by category, for one month.
- Enter the amount for each item.
- Press calculate to see the total and the share of each category.
One month, honestly counted
Use real figures from statements, not guesses; small daily spending (coffee, snacks, delivery fees) is the part everyone underestimates. A single honest month gives a truer picture than a year of estimates, and it shows exactly which category to tackle first.
Frequently asked questions
What categories should I use?
Start with housing, utilities, food, transport, debt payments, insurance, health, entertainment and personal spending. Merge or split them to match your life.
Should irregular costs be included?
Yes — divide yearly costs like insurance or car repairs by 12 and include the monthly share, so the total reflects the true cost of the month.
How does this differ from a budget calculator?
This totals what you actually spend. A budget calculator compares that spending against income and targets; the two work well together.
