One of the first questions new investors ask about gold is deceptively simple: how much? Not whether to own gold, but what share of the portfolio it should represent. There is no single right answer — but it is not arbitrary either. International research has converged on a fairly narrow range, and on a clear logic that determines whether you belong at the low end of it or the high end.
This article looks at where that range comes from, what the percentage actually does to a portfolio, how to choose your own weight, and how to translate a percentage into euros and grams of real metal.
The short answer: 2–10%, typically around 5%
The World Gold Council’s portfolio analysis concludes that a well-diversified portfolio can support a strategic gold allocation of 2–10%, with roughly 5% as the base case. Where exactly you land in that range depends on your objectives and on what the rest of the portfolio looks like. (World Gold Council)
This is an observation drawn from historical data, not a recommendation or a promise. It describes where the effect of added gold on portfolio risk and return has been most balanced. Your own number may legitimately be different.
What that percentage actually does
Concrete figures help set expectations. In the World Gold Council’s 20-year analysis, a typical portfolio (50% equities, 40% fixed income, 10% alternatives) was compared with the same portfolio holding a 5% gold allocation:
- annualised return 6.7% → 7.0%;
- volatility 9.9% → 9.6%;
- risk-adjusted return 68.1% → 72.3%;
- maximum drawdown −34.9% → −32.7%.
Note the size of the effect. A 5% gold allocation did not transform returns — it nudged them by a few tenths of a percentage point and took some of the shake out of the ride. Gold is not the portfolio’s engine; it is the suspension. Anyone expecting equity-like returns from gold is likely to pick the wrong weight and then be disappointed for the wrong reason.
Choosing your own weight: four questions
There is one guiding principle for moving within the 2–10% range: the riskier the rest of the portfolio, the larger gold’s role. The World Gold Council puts it this way — the higher a portfolio’s volatility or concentration, the larger the gold allocation needed to maximise risk-adjusted returns.
1. How volatile is everything else? A portfolio made up mostly of bonds needs less of a stabiliser than one packed with individual stocks, growth names or crypto.
2. How concentrated are you? If a large share of your wealth sits in one country, one sector or one company (your own business, for instance), the case for diversification is stronger.
3. What is your time horizon? Gold pays no dividend and no interest. Over a short horizon its price swings are pure risk; over a long one they are the premium you pay for sleeping better.
4. Can you sit through a drawdown? A more honest question than “how much could I gain” is “how much of a loss can I absorb without selling”. A weight that makes you panic is too large — regardless of what any table says.
From percentage to euros: turning a weight into a purchase
The arithmetic is easy. Five per cent of a €20,000 portfolio is €1,000; five per cent of €100,000 is €5,000. The difficulty starts when that sum has to become physical metal, because gold does not come in arbitrary sizes.
In late August, spot gold was trading around $4,600 per ounce (Kitco, 21 August 2026). For many first-time buyers, that makes a full one-ounce coin a single large block — not the wrong choice, but a piece you cannot sell half of.
In practice the decision splits three ways:
- A smaller budget, or a wish to split the purchase into several pieces — fractional coins such as the 1/10 oz Canadian Maple Leaf gold coin. The premium per gram is higher, but you can sell in parts later.
- The standard building block — the 1 oz Austrian Philharmonic gold coin. Among the most liquid coins in the world and easy to price.
- A larger sum at once — bars, such as the 100 g Argor-Heraeus gold bar, where the mark-up per gram is usually lowest and the flexibility smallest.
Some investors split the precious-metals sleeve between gold and silver. Silver swings harder, and its VAT treatment in Estonia differs from gold’s, so it is worth treating as a separate decision rather than a substitute for gold — a 1 oz silver coin is a common starting point.
Two Estonian specifics that affect the weight
VAT. The supply of investment gold in Estonia is normally exempt from VAT (Estonian Tax and Customs Board), while the standard VAT rate has been 24% since 1 July 2025 (ETCB). It is one reason a share of your money does not disappear into tax the moment you buy investment gold.
The buy–sell spread. With physical gold, your real cost of entry is not the spot price but the premium you pay on the way in and the spread on the way out. That gap matters far more to your choice of weight than the second decimal place of a percentage: a purchase so small that the premium eats a large slice of it serves the portfolio worse than a slightly larger, sensibly priced piece.
Holding the weight over time
Weights do not hold themselves. If gold rises faster than equities, 5% quietly becomes 9%; in the opposite case it shrinks to 3%. Most long-term investors review the allocation once a year and adjust only when the drift is meaningful — more than a couple of percentage points, say. Rebalancing every month generates more transaction cost than benefit when the asset is physical metal.
For context: central banks, the largest buyers of gold, move at much the same pace. In 2025 they bought 863 tonnes in total, short of the 1,000-tonne level of recent years but clearly above the 2010–2021 average of 473 tonnes (World Gold Council). They do not trade the position either. They hold it.
Frequently asked questions
Is 1% pointless? A very small allocation has a marginal effect on portfolio risk. It does no harm, but it also does not do the job gold is held for in the first place.
Is more than 10% a mistake? Not automatically — but it is a different decision from diversification. At that point you are effectively taking a view on the monetary system, and you are outside the balanced range the research describes.
Buy all at once, or in instalments? Buying regularly in smaller amounts smooths your entry price; a single larger purchase saves on premium. Neither is objectively better — it depends on which risk bothers you more.
Should the weight change with age? If a portfolio’s overall risk falls as you get older, the same logic reduces the need for a stabiliser. The decision still remains a personal one.
In summary
The research range is 2–10%, with roughly 5% as a typical starting point, and your position within it depends on how risky the rest of your portfolio is. Two practical matters count for more than pinning down the exact percentage: choosing a piece size that fits your budget and your likely future need to sell, and holding the weight consistently rather than to the rhythm of the news.
