Frequently asked questions

What does this budget calculator estimate?

It estimates your monthly expenses, total outgoings and how much money you may have left after spending and savings.

Should I use gross or net income?

For a personal monthly budget, it usually makes more sense to use net income, which is your take-home pay after deductions.

What should I include in other expenses?

You can include regular costs such as insurance, childcare, debt payments, subscriptions, healthcare, entertainment and any other recurring spending.

Does this calculator include irregular expenses?

Not unless you add them in. If you have annual or occasional bills, consider converting them into a monthly average and adding them to other expenses.

What if my remaining budget is negative?

A negative result means your current income does not cover your entered expenses and savings goal, so you may need to reduce spending, adjust savings or increase income.

Can I use this calculator for household budgeting?

Yes. You can enter combined household income and shared monthly expenses to estimate a household budget.
