The Gold-to-Silver Ratio: What It Is and How Investors Use It
How many ounces of silver does one ounce of gold buy? That simple number has swung widely over the decades. Here is how to calculate it and what it can and cannot tell you.
Key takeaways
- Gold-silver ratio = gold price per ounce ÷ silver price per ounce.
- A high ratio means silver is cheap relative to gold; a low ratio means silver is expensive relative to gold.
- The ratio has moved over a wide range in modern markets and can stay high or low for years.
- It compares the two metals; it does not say whether either one is cheap in absolute terms.
How to calculate it
Divide the gold price per troy ounce by the silver price per troy ounce, both in US dollars.
Example: gold $4,200 ÷ silver $52 ≈ ratio of 81
That means one ounce of gold buys about 81 ounces of silver. These are example numbers; use the live prices on our gold page.
Why the ratio moves
- Economic cycle: silver has big industrial uses, so it often outperforms in strong economies and underperforms in slowdowns. See Silver Price Explained.
- Fear: in crises, investors often favor gold, pushing the ratio up.
- Central banks: they buy gold but hold almost no silver, supporting gold specifically.
- Market size: silver's smaller market makes it more volatile in both directions.
How investors use it
Some precious metals investors switch between the two metals when the ratio reaches levels they consider extreme: moving into silver when the ratio is high, back into gold when it is low. Others simply use it to decide which metal to add to when they buy.
The risk is that "extreme" levels can last much longer than expected. A ratio that looks high can go higher. Trading costs and dealer premiums, which are higher for silver as a percentage of value, also eat into gains from switching.
Things the ratio does not tell you
- Whether gold or silver is a good investment at all.
- Where either price is heading next.
- The effect of storage, premiums and taxes, which differ between the metals.
