Gold Portfolio Simulator

How the calculation works

• The starting amount is split into gold and “everything else” by the share you pick.
• Each year, the gold part grows by your gold return minus your holding cost, and the rest grows by your return for everything else. A negative number shrinks it.
• With “back to target yearly”, the total is split again at your chosen share at the end of every year. With “never”, each part is left to drift.
• In a shock year, your two shock figures replace the normal returns for that one year.
• The comparison line runs the exact same inputs with 0% in gold, so the only difference between the two lines is the gold share.
• “Largest year-end fall from a peak” looks only at the year-end values the tool produces. Real markets also fall and recover inside a year, which a yearly model cannot show.

What this tool cannot tell you

• What gold, shares or bonds will actually return. Fixed yearly rates are a simplification.
• Gold pays no interest or dividend, so in this model its return is whatever you type for the price change, minus the holding cost you enter.
• Taxes, dealer buy/sell spreads, insurance and currency movements — none are included.
• What share is right for you. That depends on your situation and is a question for a qualified adviser.

Official gold reserves: selected countries

Gold held as official reserve assets, as reported to the IMF. Countries chosen for reference, not ranked as a complete list.

Source: IMF, International Reserves and Foreign Currency Liquidity (IRFCL), indicator “Official reserve assets, gold volume”, monthly (exact data query), fetched 5 October 2026. The IMF reports fine troy ounces; tonnes are converted at 1 troy ounce = 31.10348 g (NIST SP 811, Appendix B.9). “Change” compares the latest month with the same month one year earlier. The United States row is the latest month published at the time of fetching. Countries revise these figures, so later editions can differ.

Norway reports zero. In January 2004 Norges Bank announced it had sold 16 tonnes of gold bars and planned to sell the rest of its bars — the background is in why Norway sold its gold.
