THE SHORT ANSWER
An expense ratio is recurring drag, not the complete cost of owning a gold product
Annual expenses reduce the assets supporting each share and therefore compound over time. But expense ratio alone cannot rank gold products. A complete comparison adds spread, premium or discount to NAV, commission, tracking difference, tax and account fees. Copy the current rate from the product's latest prospectus; do not rely on a stale comparison table.
WORKING EVIDENCE SHEET
Reconcile an observed interval before explaining the difference
Interpretation boundary: the annual expense-only factor is a formula reference, not a forecast of tracking difference. Realized differences can also reflect benchmark clocks, product structure, cash, operational costs, distributions, pricing and market-to-NAV movement.
COMPOUNDING
Translate a headline percentage into a holding-period factor
For a simplified annual model, the remaining factor after n years is (1 - expense ratio)n. The cost is not merely expense ratio multiplied by original capital because the base changes with asset value and prior expenses. GoldObserve's gold ETF cost calculator compounds the factor alongside a user-entered gross return.
This is a comparison model, not a reconstruction of a fund's daily accrual. For a physical trust, inspect ounces of gold per share over time and the issuer's description of gold sales used to meet expenses.
THREE DIFFERENT NUMBERS
Expense ratio, tracking difference and tracking error answer different questions
Always define the benchmark and matching timestamps. Comparing a New York close with a London afternoon gold fixing can create apparent tracking noise that is mostly a clock mismatch.
PERIODIC CONSISTENCY
Calculate tracking error only from matched total-return intervals
Method boundary: input levels must already represent compatible total-return series. Price-only NAV, unmatched benchmark clocks, missing distributions or irregular observations can make the statistic misleading. Tracking error is not tracking difference and neither is a forecast.
DECISION RULE
Fee differences matter more as time and capital increase
A lower recurring charge becomes more valuable over a long horizon, all else equal. The recommendation reverses when the lower-fee product has a materially wider executable spread, persistent unfavorable NAV gaps, a structure that does not meet the investor's objective, or different tax consequences. For a small short-term trade, spread can dominate; for a long holding, recurring expense can dominate.

FREQUENTLY ASKED QUESTIONS
Gold ETF expense-ratio questions
How much does a 0.40% annual expense cost?
It depends on capital, return path and time. In a simplified no-return example, the remaining factor after n years is (1 - 0.004)^n; actual product results can differ because expense accrual and tracking are more complex.
Is a sponsor fee deducted from my brokerage cash?
Often a bullion trust pays expenses from trust assets, potentially by selling small amounts of gold. That reduces the gold represented by each share rather than appearing as a separate retail debit.
Should I always choose the lowest expense ratio?
No. Compare legal structure, tracking difference, spread, NAV gaps, liquidity at your order size, custody, tax and account fees. A tiny expense advantage may be overwhelmed elsewhere.
