Lifecycle Cost Calculator (LCC)
Calculate total cost of ownership including acquisition, energy, maintenance, downtime, and disposal — all discounted to present value over the equipment’s full life.

Lifecycle Cost Formula
The total lifecycle cost (LCC) includes all costs over the equipment’s useful life, discounted to present value:
Where Cannual = energy + maintenance + downtime, summed over n years with discount rate r.
NPV of Annual Costs (Annuity Factor)
When annual costs are constant, the NPV is computed using the present value annuity factor:
Annual Equivalent Cost
The annual equivalent cost (AEC) spreads the total LCC evenly over the equipment life:
Typical Cost Breakdown
| Equipment | Acquisition | Energy | Maintenance | Other |
|---|---|---|---|---|
| Industrial pump | 5–15% | 70–85% | 5–15% | 1–5% |
| Electric motor | 1–5% | 90–97% | 1–3% | <1% |
| Compressor | 10–20% | 60–75% | 10–15% | 2–5% |
| HVAC system | 15–25% | 50–65% | 10–20% | 5–10% |
Practical Example
Given: Acquisition = €5,000, Installation = €1,000, Energy = €500/yr, Maintenance = €300/yr, Life = 15 years, Discount rate = 5%
Cannual = 500 + 300 = €800/yr
Annuity factor = (1 – (1.05)–15) / 0.05 = 10.3797
NPV operating = 800 × 10.3797 = €8,304
LCC = 5,000 + 1,000 + 8,304 = €14,304
Acquisition share = 6,000 / 14,304 = 42%
Annual equivalent = 14,304 / 10.3797 = €1,378/yr
💡 Tip: For pumps and motors, energy costs typically dominate LCC. Investing in a higher-efficiency unit with higher acquisition cost often reduces total LCC significantly.
Lifecycle Cost (LCC) is the total cost of owning and operating an asset over its entire useful life. It includes acquisition, installation, energy consumption, maintenance, downtime losses, and end-of-life disposal costs — all discounted to present value.
LCC analysis helps make better purchasing decisions by looking beyond the initial price tag.
The discount rate reflects the time value of money — a euro today is worth more than a euro in the future. It accounts for inflation, investment opportunity cost, and risk.
- Higher discount rate — future costs weigh less, favoring low-operating-cost options less
- Lower discount rate — future costs weigh more, making energy-efficient equipment more attractive
- Typical range: 3–8% for industrial equipment
Purchase price is only the upfront acquisition cost. LCC includes all costs over the equipment's entire life:
- Acquisition and installation
- Energy consumption (often the largest component)
- Maintenance and repairs
- Downtime and production losses
- Decommissioning and disposal
For pumps, the purchase price is typically only 5–15% of the total LCC.
The split varies by equipment type:
- Industrial pumps: 5–15% acquisition, 85–95% operating
- Electric motors: 1–5% acquisition, 95–99% operating
- Compressors: 10–20% acquisition, 80–90% operating
- HVAC systems: 15–25% acquisition, 75–85% operating
Energy costs dominate for most rotating equipment.
Key components:
- Energy: Power (kW) × Annual hours × Price (€/kWh). For a 5 kW pump running 8,000 hr/yr at €0.12/kWh → €4,800/yr
- Maintenance: 2–6% of acquisition cost per year, or use historical records
- Downtime: Expected failures/yr × Hours per repair × Production loss per hour
Consult equipment datasheets for rated power and maintenance schedules.
The procedures described on this page were developed and field-tested by the Vibromera team using the Balanset-1A, a portable dual-channel balancer and vibration analyzer for on-site rotor balancing.
Professional field balancing instruments and software. Reduce energy costs and extend equipment life. Used in 50+ countries.

Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
