THE WRITTEN LESSONFollow along at your pace

Zero-based budgeting is a method where every dollar of your pay gets a job before the month begins. It takes more work than the 50/30/20 rule, but nothing is left to chance. In this lesson you learn the idea, the order to follow, a worked example and an honest look at the trade-off.

The idea

Your take-home pay, minus everything you plan for it, should equal zero. That does not mean you spend it all. Savings, extra debt payments and a small buffer count as jobs too.

The zero is on paper, not in your account. Your budget sheet can show $0 left while your bank account still holds your savings.

The equation Pay minus Plan equals $0. Three green jars labelled Savings, Extra debt and Buffer carry the note Jobs too. A sheet headed On paper shows pay of $3,000, plan of $3,000 and left $0, next to a bank card showing $250 saved.(opens the full-size picture)
Zero on paper means every dollar is planned, not spent.

First, the musts

Work in order. First, write down your take-home pay. Then fund your bills and minimum debt payments, the things that must be paid. Then turn yearly costs into a monthly line, so they do not catch you by surprise: divide the yearly amount by 12 and set that money aside each month.

If you need your take-home number, see finding your real take-home pay.

Three numbered steps. 1, Take-home pay, shows a pay slip of $3,000. 2, Bills and minimums, shows a bill and a coin. 3, Yearly costs, monthly, shows a calendar with a yearly bill divided by 12.(opens the full-size picture)
Pay first, then bills and minimums, then yearly costs spread over 12 months.

Then the rest

Next, give money to savings, extra debt payments and a buffer for small surprises. Finally, give the rest a job, like food, transport, clothes and fun, until what is left reaches zero.

The picture shows a different amount left to plan, to show how the number falls as each line is filled in. Each time you give a dollar a job, the amount left to plan gets smaller.

Steps 4 and 5. Step 4, Savings, debt, buffer, shows three green jars. Step 5, Give the rest a job, shows jars for Food, Transport, Clothes and Fun, with the amount left to plan falling from $900 to $600, $300 and finally $0.(opens the full-size picture)
The amount left to plan counts down to zero as each line is filled.

An example

Here is an example on $3,000 a month. Rent, utilities and a loan payment take $1,380. Groceries and transport take $620. Yearly costs take $100. Savings, extra debt and a buffer take $450. Fun, clothes and everything else take $450.

Add them up: $3,000 in, $3,000 planned, $0 left. Your own lines and amounts will differ.

A sheet titled My Budget with five lines: Bills $1,380, Food and transport $620, Yearly costs $100, Savings, debt, buffer $450 in green, and Fun, clothes, other $450. Beside it a pay slip of $3,000 and a card reading In $3,000, Planned $3,000, Left $0.(opens the full-size picture)
Five lines add up to the full $3,000, so $0 is left.

When a line runs out

What if a line runs out in the middle of the month? Move money from another line, the buffer or a want first, and write the change down. For example: “Moved $40 from Buffer.”

If the same line runs dry every month, it was set too low. Raise it next month. That is not failure. It is the plan getting more accurate.

An almost empty Food jar with the label Line runs out, and a note reading Moved $40 from Buffer, beside a half-full Buffer jar. A green arrow points up to a taller, fuller Food jar, with the labels Raise it next month and Set too low.(opens the full-size picture)
Move money on purpose, write it down, and raise a line that keeps running dry.

The honest trade-off

Zero-based budgeting takes more time than other methods, and a first plan can take a couple of weeks to settle. No study has tested it against the other methods for households. Its strength is simple: nothing is left unplanned.

If it feels like too much, you can start with the 50/30/20 rule and come back to this method later.

A clock labelled More time, a calendar reading Weeks 1 and 2 labelled A couple of weeks to settle, a card reading Not tested against other methods, and a tick beside the words Nothing left unplanned.(opens the full-size picture)
More time up front, and nothing left unplanned.

Welcome back. In this lesson, you'll learn zero-based budgeting: a method where every dollar of your pay gets a job before the month begins.

Here's the idea. Your take-home pay, minus everything you plan for it, should equal zero. Not because you spend it all, but because savings, extra debt payments and a small buffer count as jobs too. The zero is on paper, not in your account.

Start in order. First, your take-home pay. Then fund your bills and minimum debt payments, the things that must be paid. Then turn yearly costs into a monthly line, so they don't catch you by surprise.

Next, give money to savings, extra debt payments, and a buffer for small surprises. Finally, give the rest a job, like food, transport, clothes and fun, until what's left reaches zero.

Here's an example on three thousand dollars. Rent, utilities and a loan payment take thirteen hundred and eighty. Groceries and transport, six hundred and twenty. Yearly costs, one hundred. Savings, extra debt and a buffer, four hundred and fifty. Fun, clothes and everything else, four hundred and fifty. Three thousand in, three thousand planned, zero left.

What if a line runs out mid-month? Move money from another line, the buffer or a want first, and write the change down. And if the same line runs dry every month, it's set too low. Raise it next month.

Zero-based budgeting takes more time than other methods, and a first plan can take a couple of weeks to settle. No study has tested it against the others for households. Its strength is simple: nothing is left unplanned.

So remember: every dollar gets a job, including savings and a buffer. Fund bills first, then yearly costs, savings, and the rest. And move money between lines on purpose, then write it down. Before the next lesson, give every dollar of next month's pay a job on paper. Next, you'll try envelopes, on paper or on your phone.
