How much do I need to save each month to reach A$20,000 in 3 months?

A$6,667 a month. Set it to A$6,700 and you arrive early with a small cushion, which is usually worth more than the exact figure.

What is that per week and per day?

A$1,538 a week, A$3,077 a fortnight, and A$219.03 a day across roughly 91 days.

Which kakeibo category should the money come from?

Start with Optional. On this target it carries about 30 percent of the monthly figure, which is A$2,000. The ledger tells you the specific lines within a fortnight.

What happens if I miss a month?

The shortfall spreads across what is left. Missing one month here adds about A$3,333 to each remaining month, so it is recoverable, and the monthly reflection is where you decide whether to absorb it or move the date.

A$219.03

Money stops coming out of discretionary spending alone at A$50 a day, where the rule is drawn. This target sits above it.

A daily cost this size is not a budgeting problem. It is an income, housing or timeline problem, and the ledger is how you work out which of the three you are actually solving.

Short horizons reward preparation over willpower. Move the money the day it arrives and the remaining eleven weeks are mostly bookkeeping.

Against an income

What this asks of your income

The ladder simply runs the division backwards: A$6,667 a month is twenty percent of A$33,333, ten percent of A$66,667, and thirty percent of A$22,222. Find your own income on it and you know what you are asking of yourself.

The dark slice is A$6,667, the same money on every rung. What changes behind it is the pay packet it has to come out of, which is the whole reason a savings rate is a better question than a savings amount. The marked rung is twenty percent.

Where the money comes from

Which envelope pays for it

Kakeibo sorts spending into four envelopes rather than dozens of line items, and that is what makes a question like this answerable.

Survivalwhat keeps the lights on: rent or mortgage, groceries, power, rego and fuel, insurance
Optionaltakeaway, subscriptions and the shopping you would not miss
Culturea course, a gallery membership, books
Extrathe irregular hit: car repairs, a wedding gift, the vet

Splitting it across Optional, Culture, Extra and Survival is one way to arrange it, and the Survival line is the honest part: at A$6,667 a month, no rearrangement of takeaway, subscriptions and the shopping you would not miss covers the whole figure. Survival means fixed costs, so that share is a housing, transport or insurance decision rather than a willpower one.

Numbers in this band are usually reached by a combination of saving and one structural change. Naming the structural change is what separates a plan from a hope.

The method, against this number

The four questions, against this target

The method is four questions asked once a month, in that order. Here they are with this page's numbers in them. The long version of each, with the reflection prompts, is in the four questions guide.

01How much money do you have?Everything that lands in the month, before anything is committed. The plan below only works from a real figure rather than a remembered one.
02How much would you like to save?A$6,667 a month, or A$6,700 if you would rather set a round standing transfer and finish early.
03How much are you spending?Recorded by hand, in four envelopes, as it happens. This is the part that makes the A$20,000 possible, and the part every method skips at its peril.
04How can you improve?Answered once a month for 3 months, in writing, against the running total rather than against a feeling.

A$219.03 a day is above the A$50 a day line, so part of the money has to come out of fixed costs rather than out of Optional. Run the same A$20,000 over eighteen months instead and it drops back under.
