Second Hand Savings
A precise tool.
What is the Second Hand Savings & How does it work?
The global market for second‑hand goods is expanding rapidly, offering consumers a practical way to reduce waste while keeping budgets in check. By extending the life cycle of products, we lower the demand for new manufacturing, which in turn cuts down on resource extraction, energy consumption, and greenhouse‑gas emissions.
Financially, purchasing used items can generate substantial savings. The price gap between a brand‑new product and its pre‑owned counterpart represents the immediate monetary benefit, while the longer an item is kept in service, the more the initial cost is amortised across its useful life.
However, second‑hand items also experience depreciation. By accounting for an annual depreciation rate, we can estimate the realistic value retained over time and thus calculate the true net savings compared with buying new.
S = (P_{new} – P_{used}) times Q times left(1 – dright)^{Y}
S = total savings (USD)
