Gold and equity mutual funds aren’t direct competitors — they serve different roles in a portfolio. Gold is insurance against inflation, currency depreciation, and geopolitical shocks. Equity is the growth engine. Most balanced portfolios hold both, with gold at 5-15% and equity at the bulk. This calculator shows the maturity gap so you know what you’re trading off.

Gold’s Track Record

  • Long-term CAGR: broadly inflation-tracking over multi-decade periods.
  • Crisis-period winner: outperformed equity in 2008 (financial crisis), 2020 (COVID), 2022 (geopolitical/inflation).
  • Inflation correlation: 0.6+ over long periods — gold preserves purchasing power.
  • Drawdowns: still significant — gold dropped 30-40% in 2013-2015, took 5+ years to recover.

Equity’s Long-Term Edge

  • Compound earnings: equity tracks corporate earnings growth, which compounds at ~10-12% in mature markets.
  • Dividend reinvestment: ~1.5-2% annual return contribution from dividends alone.
  • Liquidity: instantly tradeable; gold ETFs are liquid but physical gold isn’t.
  • Higher volatility: 30%+ drawdowns happen, recover within 2-4 years usually.

Why You Should Hold Both

Gold and equity typically have negative correlation in crisis periods — when one drops, the other often holds or gains. This is exactly why portfolio theory recommends both. A 70/15/15 split (equity/debt/gold) historically beats 100% equity in risk-adjusted terms.

  • Equity provides: growth, dividends, liquidity, tax efficiency.
  • Gold provides: stability, inflation hedge, currency hedge, crisis protection.
  • Together: smoother returns, better risk-adjusted performance.

How to Hold Gold (Best to Worst)

  • Bullion-backed ETFs (best for most) — fully liquid, no storage or insurance, and the cheapest way in. Expense ratios vary more than people expect: GLDM 0.10%, SGOL 0.17%, IAU 0.25%, GLD 0.40%. On a $50,000 position that spread is $150 a year, every year.
  • Gold inside a tax-advantaged account — holding a bullion ETF in an IRA or 401(k) sidesteps the collectibles tax problem below entirely, because gains are not taxed as they are realised.
  • Gold mining ETFs (GDX, GDXJ) — not gold itself. You take equity and operational risk on miners, which is more volatile than the metal in both directions. The upside: they hold shares, not bullion, so gains are taxed at the standard 0/15/20% long-term rates.
  • Physical coins and bars — recognised bullion coins such as the American Gold Eagle typically carry a 3–8% premium over spot, more when demand spikes, plus storage and insurance. Fractional coins cost more per ounce. The offset is that recognised coins also sell back above spot, so you recover part of the entry premium.

The tax rule most gold investors miss

The IRS treats physical gold and ETFs that hold physical bullion as collectibles, not ordinary securities. That puts long-term gains on a different track from stocks.

How you hold goldLong-term capital gains treatment
Physical coins and barsOrdinary income rate, capped at 28%
Bullion-backed ETFs (GLD, IAU, GLDM, SGOL)Ordinary income rate, capped at 28%
Gold mining ETFs (GDX, GDXJ)Standard 0 / 15 / 20% long-term rates
Futures-based gold fundsTaxed as ordinary securities
Any of the above inside an IRA or 401(k)No tax on realised gains inside the account

The 28% figure is a ceiling, not a flat rate. If your ordinary rate is 12%, you pay 12%. It only bites where your ordinary rate would otherwise exceed 28% — which is precisely the higher earners most likely to hold a meaningful gold position.

The practical consequence: a top-bracket investor holding a bullion ETF in a taxable account gives up roughly 8 percentage points of after-tax return versus the 20% rate they would pay on an equity index fund — before the gold has to beat equities on anything else. That is a real headwind the headline return comparison does not show.

Worked Example

Example: $60,000/year for 15 years. Gold at 9% (after a 0.25% ETF expense ratio = 8.75% net): final value ≈ $1.88 M. Equity index fund at 10% (net 9.95% after a 0.05% expense ratio): final value ≈ $2.09 M. Equity wins by about $209K before tax. After tax the gap widens: on $900K contributed, the gold gain is taxed at up to 28% and the equity gain at 20%, leaving roughly $1.60 M against $1.85 M — a gap of about $246K. During the 2008-09 or 2020 drawdowns, though, gold-heavy investors suffered far less. Both have their seasons.

Frequently Asked Questions

How is gold taxed in the US?
The IRS classifies physical gold and bullion-backed ETFs such as GLD, IAU, GLDM and SGOL as collectibles. Long-term gains are taxed at your ordinary income rate capped at 28%, rather than the 0/15/20% that applies to stocks. Gold mining ETFs (GDX, GDXJ) hold shares rather than metal, so they keep the standard rates — and holding any of them inside an IRA or 401(k) removes the issue entirely.
How much gold should I hold?
Common allocation: 5-15% of total portfolio. Bridgewater’s All-Weather portfolio uses 7.5% gold. Higher allocations are usually argued for on currency-hedging grounds.
Why does gold do well in inflation?
Gold supply grows ~1.5%/year, much slower than monetary inflation. As currencies depreciate, gold (priced in those currencies) appreciates. It’s a hard asset whose supply governments can’t expand.
