The 50/30/20 Budget: A Simple Plan for Your Money

Most budgets fail for the same reason most diets fail: they are too detailed to survive real life. Twenty categories with exact limits work for about two weeks, until a birthday, a broken appliance or a long month makes them feel pointless. In their 2005 book All Your Worth, Elizabeth Warren and her daughter Amelia Warren Tyagi proposed something much simpler: split your take-home income into just three buckets. Fifty percent for needs, thirty percent for wants and twenty percent for savings and debt repayment.

Needs are what you have to pay to live and work: rent or mortgage, utilities, groceries, transport, health insurance and the minimum payments on your debts. The test is whether you could stop paying it next month without serious consequences. Wants are everything that makes life enjoyable but is optional: eating out, streaming services, clothes beyond the basics, trips, hobbies. The last bucket is your future: an emergency fund, savings for a goal, investments, and any debt payment above the minimum. The percentages always apply to what you actually receive, after taxes and deductions.

The power of the rule is that it gives you permission as much as limits. Thirty percent for wants means that the dinner out is not a failure — it is part of the plan. And by deciding the twenty percent first, you stop saving "whatever is left at the end of the month," which for most people turns out to be nothing. The best way to make it stick is to pay yourself first: the day your income arrives, move the savings portion somewhere separate before you spend a single peso, and live on the rest.

Treat the numbers as a starting point, not a law. In many cities, and certainly in many Argentine households, rent alone can eat a third of a salary, and needs may honestly reach sixty or seventy percent. That does not mean the method is useless; it means you adjust it. A 60/30/10 or 70/20/10 split is still a plan, and the key is to keep some savings bucket, however small, and to watch the trend. If needs keep climbing, the rule is warning you about something structural — a rent that no longer fits, a car that costs too much — long before it becomes a crisis.

To put it into practice in Mingüini, load your monthly income in Finance and enter your fixed expenses as recurring ones; that alone gives you the size of your needs bucket. After a month of logging everything else, compare: how much went to needs, to wants, and to your future? The Dashboard tab shows your net balance for the month, which should be at least your savings target. If it is not, you now know exactly which bucket is taking more than its share, and that is a much easier conversation to have with yourself than "I need to spend less."
