Where does your contingency fund stand?
Describe your building in five fields. The calculation runs as you type: the contribution it would take, the gap with what you put in today, and the year the fund would go into the red if nothing changes.
– per unit per month · – of the replacement value

Where you stand
There is no percentage to apply any more: since August 14, 2025, the contingency fund study sets the contribution, building by building.

What will cost, and when
These costs come from the replacement value and the type of building. If you have a quote, or a better idea of a component's age, correct the line: the calculation follows.
| Component | Cost today | Useful life | In | Share of the need |
|---|
The cost is in today's dollars; the calculation indexes it to inflation up to the year of replacement. "In" is the number of years before the next replacement.

What about Bill 16?
This calculator gives an order of magnitude to prepare the discussion at your meeting. It does not replace the study a professional must do: two roofs of the same age are not at the same point, and only they will go and look. The old floor of 5% of common expenses was removed from the Civil Code on August 14, 2025; the rule now is to contribute according to the study.
How the calculation works
- Each component is given a replacement cost (a share of the replacement value, depending on the type of building and the region), a useful life, and a number of years before the next replacement (from the age of the building, its general condition, and the dates you know).
- Replacements are projected over 25 years, indexed to inflation, and we look for the lowest yearly contribution, itself indexed, that keeps the balance above zero every year, starting from your current balance and at the chosen yield. This is the cash-flow method used in studies.
- The cautious scenario raises costs and inflation by 10% and shortens lives by 10%; the optimistic one does the opposite.
- The health of the fund compares your balance with what an up-to-date fund would hold: for each component, the cost multiplied by the share of its life already spent.
