What is the 50/30/20 rule?
The 50/30/20 rule was popularized by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth. It splits your after-tax income into three buckets:
- 50% needs: housing, utilities, groceries, insurance, transportation and minimum debt payments. These are things you'd still pay in a bad month.
- 30% wants: dining out, entertainment, hobbies, travel, shopping and most subscriptions.
- 20% savings and debt: emergency fund, retirement, savings goals and any debt payments above the minimum.
It's popular because it's simple. You don't track 40 categories, you just keep three ratios in balance. Treat it as a starting point, not a law. In expensive cities, needs often take 60% or more. A 60/20/20 split is still a healthy plan if the 20% for savings stays.
Why freelancers need two budgets: lean and full
Fixed-salary budgets assume the same income every month. Freelance income doesn't work that way, so one budget is always wrong: too tight in good months, impossible in slow ones. The fix is to give every category two numbers:
- Lean budget: the bare minimum. Rent, utilities, basic groceries, insurance and debt minimums. Wants are cut to zero or close to it.
- Full budget: your normal, comfortable month, including wants and real savings.
At the start of each month, look at the money you actually have (or the salary you pay yourself from your buffer) and pick the budget that fits. Your lean total is also the most important number for sizing an emergency fund. Three months of lean expenses is a solid first target.
How to use this calculator
- Enter your monthly take-home income to see your 50/30/20 targets.
- Edit the categories and amounts to match your life. Mark each one as a need, want or savings/debt.
- Compare: the bars show how your full budget splits against the 50/30/20 targets (the dark marker). The summary tells you whether this income supports a full month or calls for lean.
All amounts stay in your browser. Nothing is uploaded.
Turning the numbers into a plan
- If your full budget is more than your income, run lean this month and look at your two biggest wants first.
- If you have money left over in a full month, assign it. Unassigned money tends to disappear.
- Self-employed? Work out tax first with the tax set-aside calculator. Then turn your income into a steady salary with the irregular income calculator, and budget from that salary.
Frequently asked questions
Is the 50/30/20 rule based on gross or net income?
Net (take-home) income: what's left after taxes. For freelancers, that means income after your tax set-aside.
What counts as a need vs a want?
A need is something you'd still have to pay in a bad month: housing, utilities, basic food, insurance, transport to work and minimum debt payments. Upgrades on top, like eating out or premium plans, are wants.
What if my needs are more than 50%?
That's common, especially with high rent. Keep savings at 20% if you can and shrink wants, using something like 60/20/20. If needs are above 70%, look at housing, transport or debt costs.
What is a lean budget?
A lean budget is your bare-minimum monthly spending: only essentials. Knowing it tells you how long your savings would last in a slow month, and how low your income can drop before you have to dip into savings.
Are minimum debt payments needs or savings?
Minimum payments are needs because you must pay them. Anything above the minimum goes in the savings/debt bucket.
