50/30/20 Rule
A budgeting guideline: 50% of income on needs (rent, food, bills), 30% on wants (dining out, entertainment), 20% on savings and debt repayment.
The 50/30/20 rule is a simple budgeting framework: allocate 50% of your after-tax income to needs (rent, groceries, utilities, transport, insurance), 30% to wants (dining out, entertainment, hobbies, subscriptions), and 20% to savings and debt repayment.
It was popularised by US Senator Elizabeth Warren and is widely recommended as a starting point for people new to budgeting.
In New Zealand, the reality is that housing costs in cities like Auckland and Wellington can easily consume 40-50% of income on their own, making the 50% needs allocation tight. Many NZ financial advisers suggest a modified version — like 60/20/20 — that accounts for higher housing costs.
Why this matters
The 50/30/20 rule is useful as a benchmark, not a strict rule. If you're spending 70% on needs, that's a signal that your housing or fixed costs might be too high relative to your income. If your wants are at 40%, there's room to cut back. Use it as a diagnostic tool to understand where your money goes, then adjust based on your NZ reality.

Safe to Spend
Your available balance minus upcoming bills and savings commitments. It's the amount you can actually spend without going into the red. Steady shows this number on your dashboard.
Zero-Based Budget
A budgeting method where every dollar of income is assigned a job (expenses, savings, or debt). At the end of the month, income minus allocated amounts = zero. YNAB uses this method.
Emergency Fund
Savings set aside for unexpected expenses — car repairs, medical bills, job loss. Most experts recommend 3-6 months of living expenses. Keep it in an on-call savings account for instant access.
Sinking Fund
Money set aside for a planned future expense — holiday, Christmas gifts, car registration. Unlike an emergency fund (for surprises), a sinking fund is for things you know are coming.
