Sizing the reserve fund: a method that survives the annual meeting

Ask five board members how big the reserve fund should be and you get five numbers, usually round ones: €100,000, two years of fees, “enough for the roof”. None of them is exactly wrong, but none of them comes from the building. The right size comes from what the building will need, and when.

The method below takes an evening with a spreadsheet and the maintenance plan. It gives the board a number it can defend at the annual meeting, which matters as much as the number itself.

Start from the plan, not a rule of thumb

The reserve fund exists to pay for big, predictable work: roofs, facades, windows, pipes, lifts, heating systems. All of these belong in a decent maintenance plan with an estimated year and cost. If you don't have a plan, that is the first job. A fund sized without one is a guess.

Add up the planned work for the next 30 years and divide by 30. That is the average yearly cost of keeping the building as it is. For a 2,400 m² building from the 1970s, the list might read: windows €310,000 in year 6, roof €180,000 in year 11, pipe replacement €1.9 million in year 18, facade €260,000 in year 24, plus smaller items worth €450,000 spread over the period. That is €3.1 million in total, or about €103,000 a year: roughly €43 per m² per year, or €3.60 per m² per month.

The fund follows the cash curve

Saving the average every year is the simplest policy, but it doesn't tell you how much should be in the fund at any given time. For that, run the plan year by year: opening balance, plus contributions, minus planned work. The balance should never drop below a floor, say €40,000, kept for the burst pipe in February or the storm-damaged roof section the insurer argues about.

In the example, saving €103,000 a year from an opening balance of €150,000 covers the windows in year 6 and the roof in year 11 comfortably. The pipe replacement in year 18 is the problem. By then the fund holds roughly €1.25 million, about €650,000 short of the bill. That gap is the real decision for the board, and it is far better taken now than in year 17.

Three ways to close the gap

The first is to raise contributions now so the fund reaches €1.9 million in time. In the example that means about €140,000 a year, or roughly €4.85 per m² per month instead of €3.60. Fees stay smooth, but today's owners pay for work that will mostly benefit whoever lives there in year 18.

The second is to plan a loan for part of the project and save for the rest. This is common in Finland, where large renovations such as pipe replacements are often financed with a housing company loan that owners pay off through a separate monthly charge, and owners can usually choose to pay their share up front instead. Contributions stay lower today and the cost falls on the people who live with the new pipes. The risk is interest: the same loan costs a great deal more at 4.5% than at 2%.

The third is to look harder at the plan. Plans tend to be cautious about timing. A camera survey of the pipes might move the replacement from year 18 to year 23, which changes the curve a lot. This is not a way to avoid the work, but it is a reason to update the plan every few years instead of treating the first version as fact.

Per unit, not just in total

Owners care about their own flat's part of the fund, especially when they sell. A buyer, a bank or an estate agent will ask how much has been saved for the building and how that relates to the flat. In Estonia the repair fund is typically charged per square metre and shown on the monthly invoice, and buyers do look at it. Tracking the balance per unit, from what each flat has actually paid in, makes those questions quick to answer and keeps the board honest about where the money came from.

Review every year, adjust in small steps

Construction costs move, and in recent years many associations have seen quotes come in well above estimates written only five years earlier. Review the plan's costs each year when the budget is drafted, rerun the curve, and adjust contributions in small steps. A 5% increase every year is far easier to pass than a 40% increase once a decade, when the pipes are already leaking and every member knows it.
