How do you calculate total asset lifecycle cost?

Multiply asset count by annualized cost per asset by the scope share, then add the fixed overhaul or disposal cost. For 34 assets at $56,000/yr each at 100% scope plus $480,000 fixed, the total is $2,384,000.

What does annualized lifecycle cost per asset include?

Typically maintenance labour and parts, energy, consumables, downtime, and a prorated share of major services — everything recurring, expressed per asset per year. In the example that's $56,000 per asset annually.

What is the scope-share percentage for?

It scales the variable cost when you're modelling a partial lifecycle or a fraction of the fleet — for example 60% if you only own the asset for 60% of its life. At the default 100% the full variable cost applies.

Why separate fixed overhaul cost from the variable cost?

Major overhauls, mid-life rebuilds, and disposal are lumpy one-time events, not smooth annual spend. Keeping the $480,000 fixed cost separate stops it from being wrongly scaled by the scope percentage.

Lifecycle cost vs purchase price — why the gap?

Purchase price is a single point; lifecycle cost captures 15-20 years of operating and maintenance spend. The variable portion here, $1,904,000, often dwarfs original capital and is where repair-versus-replace decisions are actually won or lost.

Should I discount lifecycle costs to present value?

For formal capital approval, yes — money spent in year 18 is worth less than money spent today. This calculator gives the nominal total ($2,384,000 here); run an NPV alongside it for board-level decisions.

Asset Lifecycle Cost Calculator

Asset lifecycle cost (also called total cost of ownership) is the full spend to own a fleet of assets across their service life — operating, maintaining, and ultimately retiring them — not just the purchase price. Reliability engineers, EAM analysts, and capital-planning teams use it to compare repair-versus-replace decisions and to justify overhaul budgets. It matters because the sticker price is often a small fraction of the true cost; maintenance, energy, and disposal dominate over a 15-20 year life. This calculator sums a variable per-asset-year cost against the one-time overhaul, replacement, or disposal hit to give a defensible total.

What this calculator does

Estimate asset lifecycle cost across owned assets using annualized cost per asset, included life-cycle scope, and fixed replacement or disposal costs.
a maintenance or asset-management team needs to compare lifecycle cost, replacement timing, maintenance strategy, and capital planning options for a asset lifecycle plan
It computes total lifecycle cost as the per-asset annualized cost scaled by fleet size and scope, plus a fixed overhaul or disposal lump sum.

Formula used

Variable asset lifecycle cost = asset count in lifecycle model × annualized lifecycle cost per asset × lifecycle years or scope included
Total asset lifecycle cost = variable asset lifecycle cost + fixed overhaul, replacement, or disposal cost

Inputs explained

Assets in the lifecycle model:
Annualized lifecycle cost per asset:
Lifecycle years or scope share included:
Fixed overhaul, replacement, or disposal cost:

How to use the result

Use it when building repair-versus-replace business cases, capital budgets, or EAM total-cost-of-ownership models.
It uses undiscounted nominal dollars, so for long horizons or formal capital approval you should run a net-present-value version alongside it.
