Life Cycle Cost Analysis Guide 2025: Win Government Contracts With LCCA

Quick Answer: What is Life Cycle Cost Analysis?

Life Cycle Cost Analysis (LCCA) evaluates the total cost of ownership over a project or asset lifetime, not just initial purchase price. It includes construction/acquisition, operation, maintenance, and disposal costs. A higher initial cost may be the better value if it results in lower lifetime costs. Federal agencies often require or prefer LCCA.

What is Life Cycle Cost Analysis?

LCCA provides a comprehensive view of total project costs:

Why LCCA Matters

• Initial cost is often a small fraction of total cost
• Operating costs can exceed construction costs
• Helps compare alternatives objectively
• Supports value engineering decisions
• Demonstrates long-term thinking

When LCCA Is Used

• Comparing design alternatives
• Evaluating value engineering proposals
• Best value source selection
• Energy system comparisons
• Material and system selection

Example: HVAC System Selection

System A costs $100,000 to install with $15,000/year operating costs. System B costs $140,000 to install with $8,000/year operating costs. Over 20 years, System A total: $400,000. System B total: $300,000. Despite higher initial cost, System B saves $100,000 over its life cycle.

Life Cycle Cost Components

LCCA typically includes these cost categories:

Cost Categories

Initial Costs (First Costs)

Construction, equipment purchase, installation, design, permits, commissioning, and other one-time acquisition costs.

Operation Costs

Energy, water, utilities, staffing, consumables, and other ongoing operational expenses throughout the study period.

Maintenance Costs

Preventive maintenance, repairs, inspections, service contracts, and routine upkeep throughout the asset life.

Replacement Costs

Major component replacements during the study period. Equipment with shorter life than the building requires replacement.

Residual Value

Value remaining at end of study period. May be positive (salvage value) or negative (disposal costs). Reduces total LCC if positive.

LCCA Calculation Methods

Several methods are used to compare alternatives:

Net Present Value (NPV)

Most common method. Converts all future costs to present value using a discount rate. Lower NPV is preferred.

NPV = Initial Cost + Σ(Annual Cost / (1 + r)^n)

Equivalent Annual Cost

Converts all costs to annual amounts. Useful for comparing alternatives with different life spans.

EAC = NPV × (r / (1 - (1 + r)^-n))

Simple Payback

Years for savings to recover additional first cost. Simple but does not account for time value of money.

Payback = Additional Cost / Annual Savings

Savings-to-Investment Ratio

Ratio of savings to additional investment. SIR > 1 indicates the investment is worthwhile.

SIR = PV of Savings / PV of Investment

Discount Rate Selection

Federal projects typically use OMB Circular A-94 discount rates or NIST/DOE rates for energy-related projects. Current federal rate is approximately 3-7% depending on project type. Using incorrect rates invalidates the analysis.

Using LCCA in Proposals

LCCA can differentiate your proposal and support higher initial prices:

Identify Opportunities

Look for areas where your solution has lower operating or maintenance costs. Energy efficiency, durability, and reduced maintenance are common differentiators.

Document Assumptions

Clearly state study period, discount rate, escalation rates, and data sources. Evaluators will scrutinize assumptions.

Show Comparison

Compare your approach to the baseline or minimum requirement. Quantify savings and show net present value advantage.

Provide Sensitivity Analysis

Show how results change with different assumptions. This builds confidence that your conclusions are robust.

LCCA Presentation Example

Cost Category	Baseline	Our Proposal	Savings
Initial Cost	$1,000,000	$1,150,000	($150,000)
Operations (NPV)	$800,000	$500,000	$300,000
Maintenance (NPV)	$400,000	$250,000	$150,000
Total LCC	$2,200,000	$1,900,000	$300,000

Government LCCA Requirements

Several federal mandates require or encourage LCCA:

Key Requirements

NIST Handbook 135

Primary guidance for federal LCCA. Required for energy and water conservation projects. Provides methodology and discount rates.

Executive Order 13834

Requires federal agencies to consider life cycle costs in procurement decisions for sustainable facilities.

FAR Part 7

Acquisition planning should consider life cycle costs. Best value procurements often include LCC as evaluation factor.

Energy Independence and Security Act

Requires LCCA for federal building energy systems and major renovations exceeding $2.5 million.

Frequently Asked Questions

What study period should I use?

Typically match the expected useful life of the facility or major system. Federal buildings often use 25-40 years. If the RFP specifies a period, use that. Otherwise, 20-30 years is common for building systems.

How do I handle uncertainty in future costs?

Use sensitivity analysis to show results across a range of assumptions. Apply escalation rates from DOE or other authoritative sources. Document your assumptions clearly and explain your reasoning.

Will evaluators accept my LCCA?

If your methodology is sound, assumptions are reasonable, and data sources are credible, evaluators should give appropriate credit. Use federal discount rates and standard methodologies to strengthen credibility.

Should I include LCCA even if not required?

If your solution has meaningfully lower life cycle costs, absolutely. This can justify a higher initial price and demonstrate sophisticated thinking about owner value. Include it in technical approach or value engineering sections.
