Budget Calculator

A budget only works if it is simple enough to stick to. The 50/30/20 rule is the easiest place to start: split your monthly take-home pay into 50% for needs, 30% for wants and 20% for savings. Enter your income below and the planner does the maths.

The 50/30/20 rule splits your income into needs, wants and savings. Type your monthly pay to see the split.

Needs · 50%

Rent or mortgage, utilities, groceries, transport, insurance, minimum debt payments.

Wants · 30%

Dining out, subscriptions, hobbies, travel and the nice-to-haves.

Savings · 20%

Emergency fund, retirement, investments and extra debt payoff.

This is a starting guideline, not personalised financial advice. High-cost-of-living areas often need more than 50% for essentials — adjust the split to fit your reality.

How the 50/30/20 rule works

50% needs covers the essentials you cannot skip — housing, utilities, groceries, transport, insurance and minimum debt payments. 30% wants is everything that makes life enjoyable but is optional: eating out, subscriptions, hobbies and travel. 20% savings goes to an emergency fund, retirement, investments and paying down debt faster.

Treat the numbers as a target, not a straitjacket. If you live somewhere expensive, essentials may take more than half your pay — the goal is simply to see where your money goes and to keep savings a fixed, non-negotiable slice.
