How the calculator works
- Purchase cost = metal value at spot + dealer premium + sales tax or VAT on both (only if you enter a rate) + one-time fees.
- Storage is calculated year by year: the storage rate times the metal value at the start of that year, or the minimum annual charge — whichever is higher.
- Sale proceeds = metal value at the end of the period, minus the sale spread and sale fees.
- Total costs = everything paid or deducted beyond the value of the metal itself. It is the “price” of owning gold, separate from where the gold price goes.
- Scenario result = sale proceeds minus purchase and storage costs, under the annual price change you chose.
Why is the tax field empty?
Because the right number depends on where you buy, what you buy and who you are — and a default would quietly be wrong for most visitors. Two examples of how different the rules can be:
- European Union: the EU VAT Directive has a special scheme for investment gold — bars of at least 995 fineness and qualifying coins — under which transactions are exempt, with an option to tax for some traders. Gold that does not meet the definition, such as jewellery, is outside the scheme.
- United Kingdom: HMRC guidance states that investment gold is exempt from VAT, subject to an option to tax, and publishes separate guidance on which gold coins qualify.
Other countries and states apply their own sales tax or VAT rules, and some tax investment metals in full. Enter the rate that appears on your quote. If you leave the field empty, the result excludes purchase tax — that is not the same as the purchase being tax-free. Buying in Israel? See the Israel country guide, which explains the VAT position there.
Tax on a gain when you sell is not included either. For example, the US IRS states that net capital gains from selling collectibles such as coins are taxed at a maximum 28% rate. Whether a rule like that applies to you is a question for a tax adviser in your jurisdiction.
Currencies and units
The currency selector only changes the label. The calculator does not convert between currencies and does not use exchange rates — enter every amount in the currency you select. You can also enter a weight in grams, troy ounces or kilograms with a price per unit; one troy ounce is 31.1034768 grams.
What is the “annual price change to break even”?
It is the yearly change in the gold price at which your sale proceeds exactly cover every cost, with all other inputs unchanged. It is not a forecast or a target — only a way to see how far the costs push your break-even point.
What is not included
- Live gold prices or exchange rates.
- Purchase tax, unless you enter a rate; tax on gains, or any other tax liability.
- Product differences such as collectible value, card or transfer fees you did not enter, and future changes in storage tariffs.
- Tax on resale: the calculator assumes the buyback price is based on metal value with no tax added. Ask the buyer how they set their price.
