If you search this question, you’ll find a dozen different answers: 5%, 10%, 15%, even 25% or more. None of them are wrong, exactly they’re just answering slightly different questions. This guide gives you a straight answer, explains where the numbers come from, and because tax treatment changes the maths walks through what actually matters for a UK investor specifically.

For most people building a diversified portfolio, a gold allocation of somewhere between 5% and 15% of investable assets is the range most consistently cited by institutional research, wealth managers, and precious metals specialists. Within that, 10% is the figure that comes up most often as a starting point enough to make a genuine difference during periods of market stress, without crowding out growth assets like equities. Where you land within that range depends on your risk tolerance, your time horizon, and how much of your existing portfolio is already concentrated in a single asset class.

That’s the headline. The rest of this guide explains the reasoning, so you’re not just borrowing someone else’s number.

The short answer: what most experts actually recommend

There’s no single official rule for gold allocation — nothing equivalent to a pension contribution limit or an ISA allowance. Instead, there’s a cluster of independent estimates that mostly land in the same neighbourhood:

• 5–10% — the range most commonly cited by financial planners as a sensible ceiling for a diversifier that doesn’t produce income.
• 10–15% — the range many gold-focused commentators and industry bodies use, sometimes described as offering the best risk-adjusted return improvement historically.
• 2–10% — a more conservative institutional estimate, reflecting gold’s still-small footprint in most professionally managed portfolios.
• 20%+ — appears in a handful of models (such as the “Permanent Portfolio,” which allocates 25% to gold) built around all-weather, crisis-resilient strategies rather than growth.

Why the ranges differ: the lower estimates (2–10%) tend to come from analyses optimising purely for risk-adjusted return across a long historical period. The higher estimates (15–25%+) tend to come from strategies built explicitly around capital preservation and insulation from a systemic financial shock, where growth is a secondary goal. Neither is “more correct” — they’re answering different questions: “What allocation maximises my risk-adjusted return?” versus “What allocation protects me if the financial system itself is under stress?”

For most people building a conventional, long-term portfolio alongside stocks, bonds, and cash, 5–15% is a reasonable working range, with 10% as a sensible default to adjust from.

Why “how much gold” is the wrong first question

Before you land on a percentage, it helps to be clear on why you’re holding gold at all — because the right allocation depends on the job you’re asking it to do.

Gold is generally held in a portfolio for one or more of these reasons:

• Diversification — gold has historically moved differently to shares and bonds, so adding it can smooth out portfolio swings even if it doesn’t boost average returns.
• Inflation resilience — physical gold doesn’t rely on a company, government, or bank to make good on a promise; its value isn’t tied to a specific currency’s purchasing power the way cash savings are.
• A safe haven in periods of market stress — during episodes of financial system strain, gold has often behaved differently from riskier assets, which is why some investors treat it as a form of insurance rather than a growth holding.
• Tangible, direct ownership unlike a share, bond, or fund, physical gold carries no counterparty risk: nobody else’s solvency stands between you and what you own.

None of this means gold reliably outperforms other assets — over long periods, growth assets like equities have often delivered stronger average returns. Gold’s usual role is as a stabiliser and hedge, not the core engine of a portfolio. That’s precisely why the sensible allocation is a modest slice (5–15%), not a dominant one. If you’re expecting gold to be your primary growth driver, that’s a mismatch between the asset and the goal and a sign you may be asking the wrong question.

Turning a percentage into a real number

Percentages are easy to nod along to and hard to actually act on. Here’s how to translate a target allocation into something concrete:

1. Total your investable assets savings, investments, pensions, and any existing gold or silver, excluding your home and day-to-day cash reserve.
2. Pick a target percentage within the 5–15% range as a starting point (see Section 7 for how age and risk tolerance shift this).
3. Multiply your total by that percentage to get a target pounds figure.
4. Check current live prices to see roughly how much gold that buys today. Gold prices move throughout the trading day, so rather than quote a fixed figure here (which would be out of date almost immediately), use live gold prices to see today’s rate, or the dedicated live gold bar prices and live gold coin prices pages for specific products.
5. Decide how you’ll build the position in one purchase, or gradually over several months (a common approach that reduces the risk of buying everything at a single, potentially unfavourable, price point).

Worked example (illustrative only, no fixed prices assumed): if your investable assets total £150,000 and you choose a 10% target, that’s a £15,000 gold allocation. Rather than committing that in one purchase, many investors phase it in for example, across four or five purchases over six months checking live prices each time.

Does it matter whether you hold bars, coins, or both?

Direct answer: Yes because your allocation answers “how much,” but bars vs coins answers “how usable is it once you own it,” and the two interact.

Gold bars generally carry a lower premium over the spot price, which means more gold for your money particularly useful if you’re deploying a larger lump sum in one go, or if part of your allocation sits inside a SIPP (a Self-Invested Personal Pension), where Capital Gains Tax doesn’t apply on disposal in the same way it does outside a pension wrapper.

Gold coins specifically UK legal-tender coins such as the Sovereign and Britannia offer two practical advantages for a personal allocation: they’re divisible (you can sell two or three coins instead of an entire bar when you only need to release part of your holding), and, as covered in Section 6, they carry a UK tax advantage that bars don’t.

We’ve written a full breakdown of this trade-off in Gold Bars vs Gold Coins: Which Is Better for UK Investors? worth reading once you’ve settled on your target percentage, since it will shape how you actually build the position. Many UK investors don’t choose exclusively a blended approach (a core of tax-efficient coins with some lower-premium bars for bulk) is common precisely because it captures the strengths of both.

What about silver?

Direct answer: Silver isn’t a replacement for gold in a portfolio it’s usually a complement, held as a smaller, separate allocation alongside it.

Silver shares some of gold’s appeal (a tangible, physical asset with no counterparty risk) but behaves differently in two important ways: it’s typically more affordable per unit, which makes it accessible for smaller, more frequent purchases, and it carries meaningful industrial demand (electronics, solar, and other technology applications) alongside its investment role — which some investors see as a distinct source of long-term demand, separate from gold’s purely monetary role. Some third-party research has suggested a modest single-digit allocation to silver (in the region of a few percent of a portfolio) as a complement to a gold position, though — as with gold — this is a general observation, not a rule, and figures vary by source.

If you’re building out a precious metals allocation rather than a pure gold one, silver bars and silver coins are worth considering as a smaller slice alongside your gold holding, rather than instead of it.

The UK tax question nobody explains properly

This is the section most gold-allocation content written for a US audience simply skips, and it materially affects how you might structure your holding.

Direct answer: In the UK, investment-grade gold (bars and coins alike) is exempt from VAT. Separately, UK legal-tender gold coins the Sovereign and the Britannia are the two produced by The Royal Mint are exempt from Capital Gains Tax entirely, because as legal tender they fall outside the scope of CGT. Gold bars and non-UK coins don’t have this exemption; gains on them are potentially taxable, subject to your annual CGT exempt amount and your applicable rate at the time.

	UK Legal-Tender Coins (Sovereign, Britannia)	Gold Bars & Foreign Coins
VAT on purchase	Exempt (investment-grade gold)	Exempt (investment-grade gold)
Capital Gains Tax on profit	Exempt — no CGT ever applies	May be taxable above your annual CGT exempt amount
Best suited to	The core, long-term portion of a personal allocation	Larger lump sums, or holdings inside a SIPP

 

Because CGT rates and annual exempt amounts are set by the Budget and do change, we’re deliberately not quoting a specific percentage or allowance figure here always check current HMRC guidance, or our SIPP Tax Rules page, for the figures that apply right now. What doesn’t change is the underlying structure: CGT-free UK coins are usually the more tax-efficient building block for a personal (non-pension) allocation, while bars come into their own for bulk buying or SIPP-held gold, where standard CGT treatment is less of a factor. If you’re investing through a pension, our SIPP Benefits and SIPP Advice pages explain how gold fits within that wrapper.

How your ideal allocation changes over time

Your target percentage isn’t necessarily fixed for life. A few factors reasonably shift it:

• Time horizon a longer runway to retirement generally supports a smaller gold allocation (5–10%), since you have more time to ride out equity market volatility. As retirement approaches, some investors nudge the allocation up (towards 10–15%) to prioritise capital preservation over growth.
• Existing concentration if your wealth is already heavily concentrated in one asset class (for example, a large amount of a single company’s shares, or a lot of property), a slightly higher gold allocation can offset that concentration risk.
• Risk tolerance investors who are particularly uncomfortable with portfolio swings, or who are especially concerned about currency devaluation or geopolitical instability, sometimes hold towards the upper end of the range (or occasionally above it) — understanding that this comes at the cost of foregone growth elsewhere.
• Life events a lump sum from an inheritance, a business sale, or a pension transfer is a common trigger for investors to reconsider their precious metals allocation as part of a wider rebalancing.

There’s no formula that fits everyone, and we’d always encourage reviewing major allocation changes with a regulated financial adviser rather than relying on a rule of thumb alone.

Common mistakes investors make with gold allocation

• Treating gold as a growth engine, not a stabiliser. Expecting gold to outperform equities over the long run sets you up for disappointment its job is usually to smooth the ride, not lead it.
• Buying it all at once. A single lump-sum purchase means your entire allocation is exposed to whatever the gold price happens to be doing that day. Phasing purchases over several months reduces that timing risk.
• Ignoring the tax structure. Building an allocation entirely from gold bars when UK legal-tender coins would achieve the same diversification goal CGT-free is a common and avoidable inefficiency for a personal (non-pension) holding.
• Never reviewing the allocation. If gold prices rise sharply, your gold allocation can drift well above your original target purely through price appreciation, changing your portfolio’s risk profile without you making an active decision.
• Holding 100% in one form. Concentrating an entire allocation in a single large bar, for instance, can create a liquidity problem you may only be able to sell the whole thing when you actually only need to release part of it.

Forgetting storage and security. A meaningful gold holding needs a proper plan for where it’s kept — see our guide on storage options and which safe to use at home if you’re keeping some or all of it yourself.

How to review and rebalance your holding

Direct answer: Review your gold allocation at the same intervals you review the rest of your portfolio typically annually, or after a major life event and rebalance if it has drifted materially from your target.

Because gold doesn’t generate income the way dividends or bond coupons do, its share of your portfolio moves only with its price relative to your other assets. If gold rises sharply while equities are flat, your allocation can climb from, say, 10% to 16% without you buying anything further. At that point, some investors choose to sell a portion (easier if it’s held in divisible coins rather than one large bar see Section 4) and reinvest elsewhere to bring the allocation back to target; others simply let it ride if their view on gold’s role hasn’t changed. Neither is automatically “correct” but reviewing the position periodically, rather than never, is what keeps your portfolio aligned with the plan you originally set.

If you decide to release part of your holding, our sell gold bars and sell gold coins pages explain the process.

Frequently Asked Questions

What percentage of my portfolio should be in gold?

Most institutional and industry research points to a range of 5% to 15% of investable assets, with 10% commonly cited as a sensible starting point. The right figure for you depends on your risk tolerance, time horizon, and how concentrated your other assets already are.

Is 10% gold in a portfolio too much?

Not according to most mainstream research 10% sits comfortably within the commonly cited 5–15% range. It would only be considered high relative to more conservative institutional estimates (which sometimes suggest 2–10%), and low relative to more aggressive precious-metals-focused strategies.

Should I hold gold coins or gold bars for my allocation?

Both can work. Bars generally carry lower premiums, which suits larger lump sums or SIPP-held gold. UK legal-tender coins (Sovereign, Britannia) are CGT-free and divisible, which suits the core of a personal, non-pension allocation. Many investors hold a mix of both see our full Gold Bars vs Gold Coins comparison.

Does my gold allocation include silver, or is silver separate?

Typically separate. Silver is usually held as its own, smaller allocation alongside gold rather than counted within a “gold” percentage, since it behaves differently and carries additional industrial demand.

Do I pay Capital Gains Tax on gold in the UK?

It depends on the form. UK legal-tender gold coins (Sovereign, Britannia) are exempt from CGT entirely. Gold bars and non-UK coins may be subject to CGT on any gain above your annual exempt amount. Because rates and allowances change with each Budget, check current HMRC guidance or our SIPP Tax Rules page for the figures in force today.

Should my gold allocation change as I get older?

Many investors do increase their allocation gradually as they approach retirement, shifting emphasis from growth towards capital preservation. There’s no fixed rule, and any significant change is worth discussing with a regulated financial adviser.

How often should I review my gold allocation?

Review it at the same intervals as the rest of your portfolio commonly once a year, or after a major life event such as an inheritance, pension transfer, or business sale and rebalance if it has drifted materially from your target.

Can I hold physical gold inside a pension?

Yes, via a SIPP (Self-Invested Personal Pension), which can hold eligible physical gold, typically gold bars. See our SIPP Benefits and SIPP Advice pages for how this works.

What’s the difference between physical gold and a gold ETF for allocation purposes?

Both can contribute to a gold allocation, but they’re different assets. Physical gold means direct ownership with no counterparty risk, but requires storage and insurance. A gold ETF is a paper claim on gold (or gold-linked assets) traded like a share more convenient for some investors, but it introduces reliance on the fund provider and doesn’t offer the same UK CGT exemptions available on legal-tender coins.

Is it too late to start a gold allocation?

Gold allocation is generally treated as a long-term, structural part of a portfolio rather than something to time around short-term price moves. Many investors build a position gradually over months rather than trying to identify a single “right” moment to start.

How much gold should a beginner buy first?

There’s no fixed starting amount it depends entirely on your total investable assets and target percentage (see Section 3). Many first-time buyers start with smaller, recognisable products such as a Half Sovereign or a small gold bar while they get comfortable with the process, then build up towards their target allocation over time.

Where should I store my gold once I’ve bought it?

Options include a home safe, a bank safe deposit box, or professional vault storage. We offer secure, insured vault storage see our storage options and storage costs pages for details, or our guide on which safe to use at home if you’d rather keep some yourself.

Conclusion

There’s no single correct answer to “how much gold should I hold” but there is a well-supported range, and a clear process for finding your number within it. Start from 5–15% of your investable assets, lean towards 10% as a sensible default, and adjust based on your time horizon, risk tolerance, and how concentrated the rest of your portfolio already is. Once you’ve settled on a target, how you build it bars, coins, or a mix, inside or outside a pension matters just as much as the percentage itself, particularly given the UK tax advantages available on legal-tender coins.
