Enter your income and instantly see your 50/30/20 split — or customise the percentages to match your situation.
The 50/30/20 rule is the most widely used budgeting framework for people starting out. It divides your after-tax income into three categories: 50% for needs, 30% for wants, and 20% for savings and debt repayment. The appeal is its simplicity — three numbers, immediately actionable, no spreadsheet required.
It was popularised by Senator Elizabeth Warren in her book All Your Worth and has since become the default starting point for personal finance advice worldwide. Whether you follow it exactly or use it as a benchmark, it gives you a clear target to measure your actual spending against. Read more: What Is a Budget?
Needs are non-negotiable essentials: rent or mortgage, utilities, groceries, minimum debt payments, health insurance, and transport to work. If losing it would directly threaten your housing, health, or job, it is a need. The 50% target is harder to hit in high cost-of-living cities — if your needs genuinely exceed 50%, the goal is to reduce that percentage over time, not to feel guilty about it now.
Wants are the spending that improves your life but is not strictly necessary: dining out, streaming subscriptions, gym memberships, holidays, hobbies, and clothing beyond basics. The line between needs and wants is not always clean. A gym membership might feel like a need if it protects your mental health. A car might be a need in a rural area and a want in a city with good public transport. Context matters. Read: What Is Emotional Spending?
The 20% savings allocation covers three things: emergency fund building, retirement contributions, and debt repayment above the minimum. The order matters: emergency fund first (target 3–6 months of expenses), then high-interest debt, then retirement contributions. Once those are established, the savings allocation becomes wealth-building capital.

Both rules are useful starting points — the difference is in how they divide spending and what they prioritise.
| Rule | Living expenses | Savings | Best for |
|---|---|---|---|
| 50/30/20 | 50% needs + 30% wants = 80% | 20% | Most people starting out, moderate income |
| 70/20/10 | 70% living expenses (combined) | 20% savings + 10% debt/giving | Higher fixed costs, aggressive debt payoff |
| Custom | Your choice | Your choice | Anyone with specific goals or constraints |
The 70/20/10 rule is less prescriptive about the needs vs wants split — it treats all living expenses as one bucket. This suits people whose needs already consume most of their income, or who find the needs/wants distinction too blurry to be useful. Read: Simple Budgeting Methods Compared.
For many people, no — at least not immediately. High rent in major cities, student loan payments, and stagnant wages mean that needs alone frequently exceed 50% of income. This does not mean the rule is useless. It means the rule shows you the target, not a judgment.
If your needs are at 65%, you now know that the work is reducing that number — through increasing income, finding cheaper housing, or refinancing debt — not trying to squeeze an extra 5% into savings from a budget that is already stretched. The framework gives you clarity about where the real problem is. Read: Is Budgeting Worth It If You Don't Earn Much?
The most common reason people abandon budgets is that they treat budgeting as a restriction rather than a tool. A budget does not tell you not to spend — it tells you what spending looks like relative to a plan you chose. The emotional relationship with money is often the real barrier.

The 50/30/20 rule divides your after-tax income into three categories: 50% for needs (rent, food, bills), 30% for wants (entertainment, dining, subscriptions), and 20% for savings and debt repayment. It is designed to be simple enough to remember and follow without a spreadsheet.
Net income — your take-home pay after tax. Budgeting with gross income overstates what you actually have to spend. If you are unsure of your exact net amount, use a slightly conservative estimate.
This is common — especially with high rent or large debt payments. Use the custom split to reflect your actual situation rather than forcing it into a 50% needs target. The 50/30/20 rule is a benchmark, not a rule you can break. The goal is to work towards reducing your needs percentage over time, not to feel guilty for exceeding it now.
The 70/20/10 rule allocates 70% to all living expenses (needs and wants combined), 20% to savings and investments, and 10% to debt repayment or giving. It suits people who find the needs vs wants distinction too blurry to be useful, or whose fixed costs are genuinely higher than 50% of income.
