Twelve Envelopes

Two adults and a dog in Spokane, Washington, publishing the household budget one month at a time. Twelve envelopes, one spreadsheet, no advice for anybody else.

Issue 11 · July 2026

Posted Aug. 4, 2026. Covers the calendar month, not our pay periods — see the method for why those are not the same thing.

July is the month the sinking funds justified themselves. All four tires on the Corolla went at once — $402 — and the twelve envelopes never saw it, because tires have been accruing at $110 a month since March.

Notes on the month

The tires are not on this table. That is the point of them. The $402 came out of the car maintenance sinking fund, which is why the sinking‑funds row shows the flat $458 contribution and nothing else. The fund went from $588 to $186 and will not be comfortable again until about November. The sinking funds page shows the balances.

Gifts and giving, $130 over. A wedding in Coeur d'Alene. We knew the date in February and did not think to put anything aside for it, which is a straightforward planning failure and is now logged on the mistakes page. The gift was $180 and the rest was a card, flowers for the parents and parking.

Car, $18 over. Two tanks at a higher price than June, plus $22 of wiper blades that arguably belong in maintenance. We put them in the envelope because arguing about $22 is worse than paying it.

Health, $67 under. No appointments. This envelope is deliberately over‑set: it covers copays and prescriptions and it averages far below $95, but the months it goes over it goes over badly.

Eating out and fun, $26 under. Too hot to want to sit anywhere.

Net. $22 over across the twelve. Taken from the buffer, leaving $248 at the end of July.
