Every figure on this page is computed from the inputs entered, by the method stated below it. Cafmlane publishes no benchmark cost per square foot, no target utilisation, no expected asset life and no building rule: the areas, the costs, the hours and the lives are yours, and the defaults are a worked example to replace with your own.

We will send you these figures and a link back to them. One email, nothing else unless you tick the box.
Every figure starts from one worked example ($160,000). Type your own desk count, floor area, open work orders or replacement value over it and the answer moves as you type; nothing is stored and nothing is sent anywhere.

Computer aided facilities management systems hold the asset register, and the register's real purpose is to answer a financial question rather than an inventory one: what should we be putting aside every year. Enter the replacement value of the asset base, its average expected life, its average age today, and what you currently set aside, and this sheet returns the annual sinking fund the base needs, the shortfall against what you actually save, the average life remaining, the share of the base's life already consumed, the replacement value falling due within five years, and the share of the annual need your fund covers. On the worked example, $2.4m of assets over a 15 year life needs $160,000 a year; setting aside $90,000 covers 56% of it and leaves a $70,000 annual gap. The base is nine years into fifteen, so 60% of its life is used and $800,000 of replacement falls due within five years.
The gap compounds quietly
$70,000 a year of shortfall on the worked example is $350,000 over five years, arriving at exactly the moment $800,000 of replacement falls due. Neither number is alarming on its own, and together they are the whole argument for raising the fund now.
Average life is a blunt instrument, and still useful
A boiler and a door closer do not share a life, and a single average will be wrong for both. It is still the right starting figure for a small estate, and the sheet is quick enough to run again per asset class once the register is good enough to support it.
Life consumed is the number that persuades
60% of the asset base's life used is easier to act on than a depreciation schedule, because it says plainly how much of the estate's useful life has already been spent while the fund was covering just over half of what it should.
Computer aided facilities management system: what the person answering for the buildings asks first
What replacement value should I use?
What it would cost to replace today, not what it was bought for and not its book value. Insurance schedules and recent quotes are usually the most honest sources for a small estate.
Is this the same as depreciation?
Related but not the same. Depreciation is an accounting treatment of past spend; this is a forward-looking estimate of what to set aside. Your accountant owns the first and the facilities budget owns the second.
What life should I assume?
This site publishes none, because it varies by asset type, use and environment. Manufacturer guidance and your own replacement history are better sources than any figure a software vendor could offer.
