Zero-based budget
Zero-based budgetingA zero-based budget assigns every dollar of a month's take-home pay to a line, whether for investing, saving or a kind of spending, so that take-home minus everything assigned comes to zero. Nothing is left unassigned before the month starts.
What is a zero-based budget?
A budget sets amounts for its lines ahead of the month. In a zero-based budget the amounts are set until they add up to the take-home pay, so the money left to allocate is $0. A dollar not given to a spending line goes to a savings or investment line instead; it does not sit unassigned.
The zero is a planning figure, not a bank balance. It says every expected dollar has a stated purpose; it does not say the account is empty.
Envelope budgeting, in its cash form, is a zero-based budget: a paycheck is divided across envelopes until none of it remains.
How a zero-based budget works, with numbers
A household's take-home is $5,200 a month. Its plan puts $520 toward investments, $260 toward savings and $3,900 across the spending lines, which leaves $520 to allocate. That plan is not zero-based: $520 of the month's income has no line.
To make it zero-based, the $520 is assigned: $320 more to savings, bringing that line to $580, and $200 to a new car maintenance line, bringing spending to $4,100. Take-home minus the three sections now comes to $0.
- Take-home
- $5,200
- Investments
- − $520
- Savings, $260 + $320
- − $580
- Spending, $3,900 + $200
- − $4,100
- Left to allocate
- $0
Why a zero-based budget matters
An unassigned remainder is money the month can spend on anything, since no line will read as over when it goes. In the example, the $520 left unassigned is $520 that no line measures; once it is $320 more of savings and a $200 car maintenance line, each has an amount to be read against.
The zero is also the check that the lines are complete. A plan whose lines add up to less than take-home has a category that is missing or under-planned; one that adds up to more than take-home has planned money that will not arrive.
Zero-based budget in Taiga Finance
Taiga Finance does not enforce a zero, and the Plan can be run to one. The band at the top of the Plan draws everything planned across Investments, Savings and Spending against take-home; what is left is the band's tail, “Left to allocate”, whose working reads take-home minus planned, and a plan with more planned than take-home reads “Over” with the excess. On a phone the same figure reads “Left”.
Plan & goals →Key takeaways: Zero-based budget
- A zero-based budget assigns every dollar of take-home pay to a line, so take-home minus everything assigned comes to zero.
- The zero is a planning figure: it says every expected dollar has a purpose, not that the account is empty.
- Lines that add up to less than take-home leave a remainder no line measures; lines that add up to more count on money that will not arrive.
- Taiga Finance does not enforce a zero. The Plan rail shows the remainder as “Left to allocate” while it is not zero, and hides the row when it is.
Questions about Zero-based budget
What is a zero-based budget?
A budget in which the lines for investing, saving and spending are set until they add up to the month's take-home pay, so nothing is left unassigned. A $5,200 take-home with $520, $580 and $4,100 assigned to the three sections is zero-based; the same take-home with $520 unassigned is not.
Does Taiga Finance do zero-based budgeting?
It does not enforce one. The Plan saves lines that add up to less or more than take-home, and its rail shows the difference as “Left to allocate” while there is one. A plan whose lines add up to take-home shows no such row.
Does zero-based budgeting mean spending every dollar?
No. It means every dollar is assigned to a line before the month, and a savings or investment line counts.
