Hello everyone. Does anyone know of a general formula or model for figuring a rental rate for a product? Let's say I want to rent a plasma screen. How do I come up with a rate? I know that I could look up a common rental rate with other companies and have an idea, but is there a formula that I could follow to come up with the rate? Does it varies according to the product? For example take the price of the product minus depreciation plus labor, plus administrative expenses, divide it by the time....I don't know, something like that. Thank you all in advance.
