Engineering Economics Analysis Made Simple
Transform complex engineering economics calculations into clear, actionable insights. Evaluate project feasibility, calculate ROI, and make data-driven engineering decisions with confidence.
Engineering economics bridges the gap between technical feasibility and financial viability. Whether you're evaluating a new manufacturing process, comparing equipment alternatives, or justifying infrastructure investments, the numbers need to tell a compelling story.
Traditional engineering economics analysis often gets bogged down in complex formulas and manual calculations. Sourcetable transforms this process by combining the familiar spreadsheet interface with AI-powered insights, making sophisticated economic analysis accessible to every engineering professional.
Why Engineering Economics Analysis Matters
Every engineering decision has economic implications. A manufacturing engineer choosing between two production lines, a civil engineer evaluating bridge design alternatives, or a software engineer assessing cloud infrastructure options—they're all making economic decisions wrapped in technical complexity.
Consider a typical scenario: A manufacturing company needs to decide between upgrading existing equipment or purchasing new machinery. The technical specifications are clear, but the economic picture involves initial costs, operating expenses, maintenance schedules, productivity gains, and salvage values over different time horizons.
Without proper economic analysis, engineers often rely on intuition or simple payback calculations. This approach can lead to suboptimal decisions that look good on paper but fail to deliver expected returns.

Equipment Replacement Analysis
A process engineer at a chemical plant needs to evaluate when to replace aging reactors. Using Sourcetable, they model the economic life of equipment considering increasing maintenance costs, declining efficiency, and technological obsolescence. The analysis reveals the optimal replacement timing that minimizes total cost of ownership.
Manufacturing Process Optimization
A production team is choosing between three different automation solutions for their assembly line. Each option has different capital costs, operating expenses, and productivity benefits. Sourcetable's AI helps calculate the equivalent annual cost for each alternative, accounting for different project lives and salvage values.
Infrastructure Investment Justification
A municipal engineer needs to justify a new water treatment facility to city council. The analysis must consider construction costs, operating expenses, regulatory compliance benefits, and social impact. Sourcetable helps present the economic case with clear visualizations and sensitivity analysis for key assumptions.
Energy Efficiency Projects
A facilities engineer evaluates LED lighting upgrades across multiple buildings. The analysis includes upfront costs, energy savings, maintenance reductions, and utility rebates. Sourcetable calculates payback periods and net present value for different implementation phases, helping prioritize which buildings to upgrade first.
Research & Development Investment
An R&D manager must allocate limited budget among competing research projects. Each project has different success probabilities, development costs, and potential market returns. Using Monte Carlo simulation in Sourcetable, they model the expected value and risk profile of each investment option.
Lease vs. Buy Decisions
A construction company evaluates whether to lease or purchase heavy equipment. The analysis considers purchase price, loan terms, lease payments, tax implications, and residual values. Sourcetable's after-tax cash flow analysis reveals the most cost-effective financing approach for different equipment types.

Step-by-Step Examples
Example 1: Equipment Selection Analysis
A manufacturing engineer needs to choose between two packaging machines:
Using Sourcetable's engineering economics template:
The analysis reveals that Machine A has an EAC of $16,372 while Machine B has an EAC of $18,527, making Machine A the economically superior choice despite its higher initial cost.
Example 2: Project Feasibility Study
A civil engineer evaluates a proposed bridge project with the following characteristics:
Sourcetable calculates the benefit-cost ratio and net present value, accounting for the irregular renovation schedule. The AI helps interpret whether the project meets economic feasibility criteria and identifies which assumptions have the greatest impact on the conclusion.
Example 3: Make vs. Buy Analysis
An aerospace engineer must decide whether to manufacture a component in-house or purchase from a supplier:
Make Option: $75,000 equipment cost, $12 per unit variable cost, $15,000 annual fixed costs
Buy Option: $28 per unit from supplier
Using Sourcetable, the engineer models different production volumes to find the break-even point and evaluates the decision under uncertain demand scenarios. The analysis includes risk assessment and identifies the volume threshold where each option becomes preferred.
