Return on Investment Calculation
Calculating the return on investment (ROI) for siding requires comparing the initial cost, maintenance costs over the siding’s lifespan, and the potential increase in home value. For example:
ROI = [(Increase in home value – Total cost (initial cost + maintenance costs)) / Total cost] x 100
Consider a scenario where vinyl siding costs $8,000 initially, requires $500 in maintenance over 20 years, and increases home value by $5,000. The ROI would be approximately [(5000 – (8000 + 500)) / (8000 + 500)] x 100 = -40%. Conversely, fiber cement costing $15,000 initially, needing $1000 in maintenance over 50 years, and increasing home value by $10,000 would yield a positive ROI. This demonstrates the importance of considering long-term factors. Note that home value increases are estimates and depend on various market factors.
Cost vs. Durability Comparison
The following description illustrates a cost vs. durability comparison chart for three popular siding materials: vinyl, fiber cement, and wood.
Imagine a chart with “Cost” on the horizontal axis and “Durability (Years)” on the vertical axis. Vinyl siding would be represented by a point relatively low on the cost axis and low on the durability axis (e.g., $8000, 20-30 years). Fiber cement would be higher on both axes (e.g., $15,000, 50+ years). Wood siding would fall somewhere between, depending on the type of wood and level of maintenance (e.g., $20,000, 20-50 years). The visual would clearly show the trade-off between initial cost and longevity, with fiber cement showing a potentially better long-term value despite higher initial expense.
