Engineering economics is a critical field that involves the application of economic principles to engineering projects and decisions, enabling engineers and managers to evaluate costs, benefits, investments, and financing options accurately. This paper explores several fundamental problems encountered in engineering economics, including loan repayment calculations, investment project evaluations, vehicle ownership cost analysis, equipment capital costs, financing interest rates, project evaluation metrics like IRR, depreciation methods, and cost comparisons in infrastructure projects.

One core aspect of engineering economics is determining the required annual payments to settle loans. For example, a firm needing to borrow $300,000 at 9% interest over five years can calculate the equal annual payment using the capital recovery factor (A/P) in conjunction with the loan amount. In this case, the annual payment is approximately $77,127.74. This method ensures that the firm can plan its cash flows to fully repay the borrowed amount with interest, facilitating sound financial planning (Weyand & Batta, 2020).

Investment project evaluation often involves calculating the equivalent annual worth (AE) at a specified interest rate, allowing comparisons between different projects with varying cash flows and lifespans. For instance, projects with cash flows over three years are analyzed at 13% interest rate to determine acceptability. Projects with a positive AE are generally acceptable, whereas negative AE indicates rejection. The calculation employs present value factors such as (A/P), (A/F), and (A/G) to convert cash flows into uniform annual amounts, simplifying comparisons and decision-making (Gordon, 2019).

Vehicle ownership cost analysis evaluates the total cost of owning and operating a vehicle over specific periods. For example, calculating the ownership cost of a smart car over three and five years involves subtracting the percentage of residual value retained at 36 months from the initial price, then adding interest costs calculated at 6%. This approach helps consumers make informed decisions based on total ownership expenses, including depreciation, financing costs, and residual value (Liu & Kuo, 2020).

In equipment investment analysis, capital costs are computed considering purchase price, salvage value, useful life, and discount rates. For a soldering machine costing $248,000, with a salvage value of $43,000 and a useful life of five years, the capital cost is determined using the (A/P) and (interest rate) factors, resulting in approximately $73,299 at 18% interest. Such calculations assist in determining the economic feasibility of capital investments and their contribution to production capacity (Tay et al., 2018).

Loan financing terms are also analyzed to find the effective rate of return (interest rate) offered by dealerships on vehicle loans. For a car priced at $25,000 with a $3,000 down payment and a financed amount of $22,000, monthly payments of $547.47 over 48 months correspond to an effective annual interest rate around 9.38%. Calculating this involves solving the present value equation for i, providing insight into the true cost of financing for consumers (Miller, 2019).

Project evaluation using Net Present Value (NPV) and Internal Rate of Return (IRR) enables comparison of multiple investment options. For example, four projects with different cash flow sequences are analyzed. Project B exhibits the highest IRR at approximately 82.72%, indicating the most profitable investment. NPV calculations confirm these rankings, emphasizing the importance of IRR as a decision criterion, provided cash flow patterns are appropriate (Brealey et al., 2021).

Estimating project viability also involves considering future cash flows, such as cash flow of $3,000 in the initial period, and $2,035 in subsequent years, assuming IRR at 10%. If the computed NPV at the minimum acceptable rate of return (e.g., 8%) is positive, the project is considered acceptable. This underscores the importance of selecting appropriate discount rates aligned with organizational thresholds (Ross et al., 2020).

Infrastructure project choice depends on cost analysis over the life cycle employing present worth calculations. For instance, two highway routes—long and shortcut—are compared over 40 years considering capital costs, maintenance, and operational expenses. The long route's annual total costs approximate $2.28 million, slightly higher than the shortcut's $1 million. Such economic evaluation guides optimal infrastructure investments aligning with cost-effective planning (Kumar & Singh, 2019).

A comprehensive understanding of capital expenditures involves classifying costs into capitalized or operational expenses. Capital expenditures like land purchase, machinery, and infrastructure installation are capitalized and depreciated over time, whereas routine maintenance or minor repairs are expensed immediately. For example, purchasing land at $300,000 and installing a conveyor system at $55,000 are capitalized, impacting financial statements and tax calculations (Higgins, 2020).

The depreciation of assets is modeled using various methods such as Straight-Line (SL) and Double Declining Balance (DDB). Calculations involve initial cost, salvage value, useful life, and depreciation rates. For a $130,000 asset with 5 years of useful life and $20,000 salvage value, DDB approximates a higher depreciation earlier in the asset's life, reducing book value more rapidly. This affects investment analysis and tax planning (Benjamin & Blanchard, 2018).

In conclusion, engineering economics encompasses a wide range of mathematical tools and financial principles essential for informed decision-making in engineering projects. From loan amortization and investment appraisal to depreciation and infrastructure costing, these methods ensure that projects are financially viable and align with organizational goals. Mastery of these concepts enhances the ability of engineers and managers to optimize resource allocation, investment timing, and operational costs, ultimately leading to more successful project execution and sustainable economic growth.
