Lifecycle Cost Analysis (LCCA)

Lifecycle cost analysis takes the costs an asset accumulates and asks when the total, spread across the years it has run, stops falling. Early on, the purchase price dominates and spreading it over more years keeps reducing the annual cost. Later, maintenance rises faster than the depreciation benefit. The crossover is the economic replacement point.

The result is a curve rather than a date, and it is usually flatter than people expect. That matters practically: a fleet that cannot replace on the optimum year is often not far off if it replaces a year or two either side, which is a much more useful thing to tell a finance director than a single number that will be missed.

The public-sector version has to carry constraints the arithmetic does not know about. Grant-funded vehicles may come with conditions on how long they must be kept. Emergency apparatus is often held well past its economic point because the replacement cost is large and lumpy. Seasonal equipment accumulates age without accumulating miles, so mileage-based curves say very little about it.

GFOA frames the same discipline at the level of the whole asset portfolio rather than the single vehicle, recommending that a jurisdiction build a detailed capital asset life cycle model through multi-year capital planning. That is the version a fleet manager should aim to be part of, because it is the one finance already recognizes.
