A simple division
The gold–silver ratio divides the price of gold by the price of silver, using the same currency and weight unit. In a hypothetical example, gold at USD 3,000 per troy ounce and silver at USD 30 per troy ounce produce a ratio of 100. One ounce of gold then has the same quoted metal value as 100 ounces of silver. This comparison is about prices, not how frequently the elements occur in the Earth or how much of each metal has been mined.
Either price can move it
Keep gold at USD 3,000 and increase silver to USD 40: the ratio falls to 75. Keep silver at USD 30 and increase gold to USD 3,300: it rises to 110. These examples show why the numerator and denominator both matter. A falling ratio does not require silver to rise. If gold falls to USD 2,700 while silver stays at USD 30, the ratio falls to 90. It describes silver's relative performance against gold, not necessarily a positive return measured in money.
Compare like with like
Use quotations with a consistent basis. Mixing a retail gold-coin price with a wholesale silver reference price adds product premiums to what appears to be a comparison of the metals. Different timestamps can also distort a snapshot when prices are moving. Futures prices introduce delivery dates and contract terms that need to be aligned. The ratio is most interpretable when currency, unit, instrument and observation time are made explicit. A chart should say which price series were divided and when they were observed.
A description, not a destination
The arithmetic does not identify a fair ratio or promise a return to a historical average. Different demand patterns, supply conditions and investor behaviour can change the relationship. A high reading alone does not establish that silver is cheap, and a low reading does not establish that it is expensive. The ratio can organise a question about relative prices, but answering that question requires more evidence. Buying or selling either metal also introduces costs that the simple price ratio leaves out.
