There are four ways to support a price on something of value:
- replacement cost: “How much would it cost to replace?”
- market comparison: “How much are other things like this selling for?”
- discounted cash flow/net present value: “How much is it worth if it can bring in money over time?”
- value comparison: “Who is this particularly valuable to?”
Value Comparison is typically the optimal way to price your offer, since the value of an offer to a specific group can be quite high, resulting in a much better price.
