50/30/20 budget split.

Needs (50%)

Wants (30%)

Savings (20%)

Worked example

Take $6,000 of net pay landing in your account each month, after PAYG tax and the Medicare Levy. The 50/30/20 rule splits this into three buckets. Needs take 50 percent, which is $3,000, and cover rent or mortgage, groceries, utilities, insurance, and transport. Wants take 30 percent, which is $1,800, for dining out, subscriptions, hobbies, and travel. The final 20 percent, which is $1,200, goes to savings and extra debt repayment above any minimums. The split works on take-home pay rather than gross salary, because you can only allocate the money that actually reaches you after tax.

How it is calculated

The calculator applies the 50/30/20 rule to your monthly take-home income. It multiplies the figure by 0.5 for needs, 0.3 for wants, and 0.2 for savings and extra debt repayment, so the three buckets always add back to the full amount. The rule is a starting framework rather than a strict law. In high-cost cities like Sydney and Melbourne, rent alone can push needs well above 50 percent, in which case it is more useful to protect the 20 percent savings floor first and treat the rest as flexible. The savings bucket is meant for genuine wealth building, such as an emergency fund, extra Super, a home deposit, or paying down high-interest debt faster than the minimum.

Frequently asked questions

50/30/20 in high-cost cities?
Sydney and Melbourne renters often exceed 50% on needs due to high rents. Adjust to 60/20/20 or focus on protecting the 20% savings floor first and treat the remainder as flexible. The ATO does not prescribe a spending ratio, so the rule is a guideline rather than a legal requirement.
Does the 50/30/20 rule apply to gross or net income?
The rule applies to your net take-home income after PAYG tax, the Medicare Levy (2% of taxable income), and any salary sacrifice contributions are deducted. Using net income ensures you are only allocating money that actually reaches your bank account, which gives more accurate and actionable budget figures.
What counts as a need versus a want?
Needs are non-negotiable expenses required to live and work, such as rent or mortgage repayments, groceries, utilities, health insurance, and essential transport. Wants are discretionary spending like dining out, streaming subscriptions, gym memberships, and holidays. If you could reasonably live without it for a month, it is likely a want rather than a need.
How does Super fit into the 50/30/20 rule?
Compulsory employer Super Guarantee contributions (currently 11.5% of ordinary time earnings for 2025/2026) come out of your gross pay before you receive your net income, so they are not counted in the 50/30/20 split. Any voluntary after-tax contributions to Super, such as personal contributions under the annual non-concessional cap of $120,000, should be counted within your 20% savings bucket.
