Frequently Asked Questions

How does the budget calculator work?
Enter your monthly take-home income and your expenses across categories. The calculator totals your expenses and subtracts them from your income to show your monthly surplus or deficit.
What is the 50/30/20 rule?
The 50/30/20 rule suggests: 50% of after-tax income on needs (housing, food, utilities), 30% on wants (dining, entertainment), and 20% on savings and debt. A useful starting framework for anyone new to budgeting.
How much should I spend on housing?
A common guideline is no more than 30% of gross income on housing including rent or mortgage, council tax and insurance. In cities like London or Sydney this may be hard to achieve, but it remains a useful benchmark.
What if I have a deficit?
Identify which categories are highest relative to income. Look at fixed costs first (subscriptions, insurance) before variable ones. Even a small monthly surplus invested consistently makes a significant difference over time.
