Where the month ended
Thirty days. Ninety-three transactions. $6,381 out against $6,190 in.
The Okonjos volunteered for this after reading our first Ledger, and their stated reason was that they wanted to see the grocery number. Everybody wants to see the grocery number. It is the line households are most convinced they know and most consistently wrong about, and in this case the household’s own estimate before the month began was $1,050.
It was $1,412.
The nineteen trips
Four planned shops. Fifteen unplanned ones. The planned trips averaged $208; the unplanned averaged $39 and were, without exception, for between one and four items — milk, bread, something for a lunchbox, something somebody had promised to bring.
It is the most consistent pattern in everything we log, and we have since taken it apart across four households. The household noticed it on about day eleven, and to their credit they did not change their behaviour, which is what we ask. A Ledger that gets improved while it is being kept is not a record of anything.
The birthday
$410 across three transactions, for a 16-year-old. The household included it without hesitation and asked only that we not itemise the gift, which we have not.
It is the largest discretionary line in the month and it is the one they were least apologetic about, which is the sort of thing you only learn by asking households to write everything down rather than by asking them what they value.
The last four days
The month ended $191 down, and the ending is the shape of the whole thing: on days 27 through 30 the household spent $84 in total, against a daily average of $213 across the rest of the month. Nothing broke. They simply stopped.
Every household we have run a Ledger with does this. Nobody plans it. It is not in anybody’s budget and it does not appear in any advice column, but four days of near-zero spending at the end of a month is the most common household financial instrument in America.

Questions we get
- What is a Ledger?
- A thirty-day spending diary kept by one household and published without editorial judgement on any line item. The household logs every dollar as it is spent, we verify the totals against statements, and we categorise consistently across every Ledger so that months can be compared to each other rather than to a budget.
- Why 19 grocery trips in a month?
- Because fifteen of them were not planned. This is the most consistent finding across the Ledgers we have run: households do not overspend on groceries in the big shop, they overspend in the small ones. The Okonjos' four planned trips accounted for $831 of the $1,412; the fifteen unplanned ones accounted for $581, at an average of $39 each.
- Is spending $388 a month on eating out a lot?
- We do not answer that, on purpose. The Ledger publishes what a household spent, not what we think of it. What is worth noticing is the transaction count: 22 purchases for $388, an average under $18, which is a pattern of small frequent buys rather than restaurant meals.
