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.
