Total Costs: These include the initial purchase price, installation costs, ongoing electricity and water consumption, maintenance and repair expenses, and any associated fees.
Timeframe: The ROI calculation should be performed over a defined period, such as one year, three years, or five years, to reflect the long-term financial impact.

To illustrate, consider a restaurant that spends $10,000 annually on waste disposal. After installing an industrial disposer costing $12,000 (including installation), the restaurant reduces its waste disposal costs by 70%, saving $7,000 per year. The annual operational costs (electricity, water, maintenance) are $1,

000. In this case

Total Benefits (Year 1): $7,000 (waste disposal savings)
Total Costs (Year 1): $12,000 (initial investment) + $1,000 (operational costs) = $13,000
ROI (Year 1): (($7,000 – $13,000) / $13,000)
– 100 = -46.15%.

However, in year two, the initial investment is amortized, and the ROI becomes positive.

Total Benefits (Year 2): $7,000 (waste disposal savings)
Total Costs (Year 2): $1,000 (operational costs)
ROI (Year 2): (($7,000 – $1,000) / $1,000)
– 100 = 600%

This demonstrates that the initial investment can take time to recoup, but the long-term savings can be significant.
