THE WRITTEN LESSONFollow along at your pace

The 50/30/20 rule is the simplest budget method there is. It splits your take-home pay into three parts, so you only have to remember three numbers. In this lesson you see how it works, how to bend it when life is expensive, and how to use it as a quick check.

The split

Here is how it works. Fifty percent of your take-home pay goes to needs. Thirty percent goes to wants. Twenty percent goes to savings and to paying down debt.

If you need a reminder of the difference between needs and wants, see needs, wants, fixed and variable costs earlier in this course.

One long bar labelled Take-home pay, split into three parts: 50% Needs in blue, 30% Wants in orange and 20% Savings in green. Below them are a house labelled Rent, groceries, bills, a screen labelled Things you enjoy, and a jar of coins labelled Savings and debt.(opens the full-size picture)
One bar, three parts: needs, wants, and savings with debt.

An example

Say you take home $3,000 a month. Then $1,500 goes to needs, like rent, groceries and bills. $900 goes to wants. And $600 goes to savings, an emergency fund or extra debt payments.

These are round example numbers. Your own numbers will differ, and the next sections show how to adjust them.

A pay slip showing $3,000 every month, and three jars: Needs $1,500 for rent, groceries and bills, Wants $900, and Savings $600, with the notes Emergency fund and Extra debt payments.(opens the full-size picture)
$3,000 splits into $1,500, $900 and $600.

Net, not gross

One important detail: use your take-home pay, not your gross pay. If you split your gross pay, you would be planning to spend money that has already gone to tax. If you are not sure of your number, go back to finding your real take-home pay.

Two bars. The gross bar, $4,000, is crossed out and has a red top part labelled Already gone to tax. The take-home bar, $3,000, is green with a tick. A pay slip showing $3,000 is on the right, with the labels Use take-home pay and Not gross pay.(opens the full-size picture)
Split the green bar, not the crossed-out one.

A guide, not a law

The rule is a teaching guide, not a tested law. A government consumer agency that teaches it says plainly that not everyone can follow it.

If your rent alone takes half your pay, your needs might be 65 percent. That is fine. In that example, wants might be 25 percent and savings 10 percent. The numbers are an illustration, not a target to hit.

A card reading A guide, not a law, and a quote card reading Not everyone can follow it. Two bars below: The rule at 50% needs, 30% wants and 20% savings, and High rent at 65% needs, 25% wants and 10% savings, with a tick and the words That's fine.(opens the full-size picture)
A high-rent split of 65, 25 and 10 is fine.

Adjusting the split

When needs take more, take the difference from wants first, and keep something going to savings, even if it is small. A small habit is worth keeping because it is the one you can grow.

As your income grows or your costs fall, move back toward 20 percent for savings and debt.

Three jars: Needs (fuller), Wants and Savings (a little in it). A red dashed arrow moves from Wants to Needs. An upward arrow points to 20 percent. Labels read Take from wants first, Keep something for savings and Grow back toward 20%.(opens the full-size picture)
Needs grow from the wants jar first. Savings keeps a little.

If you are in debt

The savings part of the rule includes paying down debt. If debts are the bigger worry, a free money or debt advice service in your country can help you plan.

Use it as a check

The best use of the rule is as a check. Add up your real needs, wants and savings from your categories, and compare them with 50/30/20. It shows you at a glance where your money leans.

In the example below, needs are 58 percent, wants 37 percent and savings only 5 percent. That tells you where to look first: the wants, and the small savings.

Two stacked bars. The 50/30/20 rule shows 50% needs, 30% wants and 20% savings. Your real month shows 58% needs, 37% wants and a red 5%. An arrow marked Leans here points at the wants, and a note says Only 5% to savings.(opens the full-size picture)
Your real month next to 50/30/20 shows where the money leans.

Welcome back. In this lesson, you'll try the simplest budget method there is: the fifty thirty twenty rule. It splits your take-home pay into three parts.

Here's how it works. Fifty percent of your take-home pay goes to needs. Thirty percent goes to wants. And twenty percent goes to savings and paying down debt.

Say you take home three thousand dollars a month. Fifteen hundred goes to needs, like rent, groceries and bills. Nine hundred goes to wants. And six hundred goes to savings, an emergency fund, or extra debt payments.

One important detail: use your take-home pay, not your gross pay. If you split your gross pay, you'd be planning to spend money that already went to tax.

The rule is a teaching guide, not a tested law. A government consumer agency that teaches it says plainly that not everyone can follow it. If your rent alone takes half your pay, your needs might be sixty-five percent. That's fine.

When needs take more, take the difference from wants first, and keep something going to savings, even if it's small. As your income grows or your costs fall, move back toward twenty percent.

The best use of the rule is as a check. Add up your real needs, wants and savings from your categories, and compare them with fifty thirty twenty. It shows you at a glance where your money leans.

So remember: fifty percent needs, thirty wants, twenty savings. Split your take-home pay, not your gross pay. And treat it as a guide to check against, not a law. Before the next lesson, compare your own needs, wants and savings with fifty thirty twenty. Next, you'll try zero-based budgeting, and give every dollar a job.
