Monthly budget and expense calculator
This budget calculator helps you see exactly where your money goes each month. Enter your take-home income and your main expense categories, and it shows how much you have left over (or how much you are overspending). It also gives you 50/30/20 targets — a simple, popular rule for splitting income between needs, wants, and savings.
The 50/30/20 budgeting rule
The 50/30/20 rule suggests spending about 50% of your take-home pay on needs (housing, bills, food, transport), 30% on wants (eating out, hobbies, subscriptions), and putting 20% towards savings or paying off debt. It is a flexible guide rather than a strict rule, but it is a great starting point for taking control of your finances.
Turning a surplus into savings
If you have money left over, putting it to work makes a big difference over time. See how regular saving grows with our compound interest calculator, or plan for the long term with the retirement calculator. If you are overspending, the category breakdown shows where to trim first.
Frequently asked questions
Should I use gross or take-home income?
Use your take-home (after-tax) income, because that is the money you actually have to budget with.
