The worksheet came off the printer warm, one page, a column for income and a longer column for costs, and it went onto the kitchen table between a small calculator and two piles of paper: rent receipts on the left, utility bills on the right, a mug of tea standing guard over both. At the board we keep the rental budget sheet filed under instruments. It was the little machine for thinking that the old listings portals gave away beside the advertisements, and it deserves a note of its own.

Two piles on the table

The two piles are the data, and every budget sheet begins by asking you to assemble them. The receipts say what staying costs; the bills say what the dwelling adds to the rent that the rent never mentions. The sheet sat exactly between the classified column and the signature on the lease, which is to say it came at the moment the hunt turned serious. Circling a listing cost a pencil. Ringing the number cost a telephone call. Working the sheet cost an evening, and it was the first act of the search that produced something durable: a number of your own, arrived at privately, before any landlord's number had a chance to anchor it. That sequence mattered. The reader who came to the telephone already knowing their figure negotiated from their own arithmetic rather than the advertiser's.

What the sheet asked

Rent first, always the top line, then the additions the advertisements never priced. Heat and hydro, included or not, a question that changed the real rent by a meaningful margin and that the column handled with three letters, incl, doing heavy work. Parking, if the street did not supply it. Laundry coinage, the small weekly toll nobody totalled until the sheet asked. The telephone line, and later the internet line, which arrived in the budget the way it arrived in the flat, quietly and then permanently. Contents insurance, the line nobody ticked until the year they had to. And finally the cost of the move itself, which the honest sheets made you write in even though it happened once, because once was exactly what was coming. Income went at the top, and the honest sheets asked for take-home, not salary, a distinction the optimistic learned once.

The first-month sum

The calculation that justified the whole exercise was the first-month sum, the heaviest number a tenant ever faces, and the sheet existed to make it a figure you could look at in advance rather than learn. First month plus last month, where the province ran on rent deposits; first month plus the security deposit, where it ran on those, each jurisdiction keeping its own rules about how much could be asked and when it had to come back. Then the one-time costs stacked beneath: the hookup charges, the truck or the van rental, the boxes, the overlap days when two rents ran at once, the cleaning supplies, the first grocery shop for cupboards that were bare in the specific way of a first morning. Written out in a column, the first month always came in heavier than intuition promised. That was the sheet's entire argument for existing.

The rule of thumb

Every sheet carried its rule of thumb, the share of income a household could prudently give to rent, and the fraction varied with the era and the pamphlet. We note it the way the better sheets presented it: as a starting post, not a verdict, a fence to pace rather than a wall. Different markets ate different shares, and the reader in a tight city learned quickly that the official fraction described an official Canada that was not necessarily theirs. The rule's real function was not to forbid but to flag: a rent that broke the line sent you back to the two piles to find the offset, and a rent that broke it badly sent you back to the column to circle a different district. The thumb measured nothing precisely. It just asked, on paper, before the viewing, the question the listing could not: what does this number leave.

Why the portals gave it away

The old listings portals offered the worksheet as a download, and the giveaway was strategic in the most respectable sense. It cost them nothing to host and it kept the reader: a searcher who printed the sheet from a portal carried that portal's header onto the kitchen table, where the real decisions were made. It answered the question the listing could not, can I afford to ring this number, which made the site a utility and not merely a board. And it was good manners, in the way the best of the old portals understood manners: the advertisement sold the landlord's flat, and the worksheet minded the reader's interest, and a sheet that did both was a sheet worth bookmarking. The worksheet was the portal's way of sitting on the tenant's side of the table for one page.

What the numbers could not hold

For all its discipline, the sheet kept its own silences. It could not price the commute the cheaper district added, or the draft under the door that the heating line would discover in February, or the flatmate who left in month three and took their share of the arithmetic with them. It could not hold the renter's luck, good or bad, which the lettings market distributes without reference to any column. At the board we still recommend the exercise the sheet taught, because the exercise outlived the sheet: write the real month before the first real month, in pencil, on paper, between the two piles. Arithmetic is the one viewing you can do at the kitchen table, and the only one that never once lied about the rooms.
