Work backward from a future gold price to determine how much purchase premium a gold bar can carry before the transaction stops breaking even after resale costs.
The calculation compares a modeled future net resale value with today's spot-metal benchmark. It then determines how much additional purchase premium can be paid while still meeting your chosen return target.
A premium can be economically tolerable under one future-price scenario and unattractive under another. This calculator makes that relationship explicit rather than treating the purchase premium as an isolated percentage.
A negative result means that under your chosen future-price, resale-cost and return assumptions, even a purchase below today's spot-equivalent metal value would not meet the target return. That is a scenario result, not a statement about what a dealer must charge.
It is the highest purchase premium compatible with the selected future price, resale discount, costs and desired return.
Yes.
No. You provide the future-price assumption.
