The gold/silver ratio tells you how many ounces of silver it takes to buy one ounce of gold. If gold is $4,000 and silver is $50, the ratio is 80. Investors use it as a rough guide to whether silver looks cheap or expensive relative to gold, but it has no fixed “normal” level and it does not predict prices.
How to calculate it
Divide the gold price by the silver price, using the same currency and the same unit. The currency makes no difference: the ratio is identical in pounds and in dollars, because the exchange rate cancels out.
- Gold $4,000, silver $50: 4,000 / 50 = 80.
- Gold $4,000, silver $80: the ratio falls to 50 because silver has risen more.
- Gold $3,000, silver $25: the ratio is 120 because silver has lagged.
These figures are illustrations only. For current prices see our UK gold prices and UK silver prices pages.
Use spot prices rather than dealer prices. UK dealer prices for silver include 20% VAT and a larger premium, so a ratio worked out from retail prices comes out lower than the market ratio.
Historical levels
For centuries the ratio was set by law. Since 1971, when both metals have traded freely, it has moved across a wide range.
| Period | Ratio (approx.) | What was happening |
|---|---|---|
| 1792, United States | 15 | The Coinage Act fixed an official ratio of 15:1 |
| 1803, France | 15.5 | Official bimetallic standard |
| January 1980 | about 17 | Silver reached about $49 during the Hunt brothers episode |
| April 2011 | about 31–32 | Silver again approached $50 |
| March 2020 | above 120, a record | Market panic at the start of the pandemic |
| Late January 2026 | about 45–46 | Silver set a record above $120 an ounce |
After its late-January 2026 peak silver fell sharply. On 30 January 2026 it lost roughly a quarter of its value in a single day, its worst day since 1980, and the ratio climbed again. Moves like this show how unstable the measure can be. You can see the longer picture on our gold price chart.
How investors use the ratio
As a buying guide
Some people buy more silver when the ratio is high (say above 80–90) and more gold when it is low (say below 50). The reasoning is that past extremes did not last. There is no guarantee that this will continue.
For metal-for-metal switching
A more active approach is to swap gold for silver when the ratio is high and back again when it is low. The aim is to increase the number of ounces held, not the value in pounds. With 1 ounce of gold at a ratio of 90 you could in theory get 90 ounces of silver. If the ratio then fell to 60, those 90 ounces would in theory buy back 1.5 ounces of gold.
As a sentiment gauge
A sharp rise in the ratio often coincides with market stress, because silver is more sensitive to industrial demand. That was the case in March 2020.
The hidden costs in the UK
The theory ignores costs, and in the UK they are significant. Investment gold is VAT-exempt, but silver bars and coins bought for delivery carry 20% VAT, which you do not get back when you sell. Dealer spreads on silver are also wider than on gold. Some dealers offer storage in a bonded warehouse where VAT is not charged while the metal stays there; it becomes payable if you take delivery.
An illustrative switch at a ratio of 90, for metal delivered to you:
- You sell 1 ounce of gold at a buy-back price about 2% below spot.
- You buy silver at about 26% above spot (20% VAT plus a premium). You receive roughly 70 ounces, not 90.
- The ratio falls to 60. You sell the silver about 10% below spot and buy gold about 2% above spot.
- Result: roughly 1.03 ounces of gold instead of the theoretical 1.5.
So the ratio has to move a long way just to cover costs. Tax matters too. Each sale is a disposal for Capital Gains Tax, although gains on Sovereigns and on gold and silver Britannias are exempt because they are legal tender. Gains on bars and non-UK coins count towards your annual exempt amount.
Why there is no “correct” ratio
- The metals have different demand. In 2024 industry used a record of about 680 million ounces of silver, more than half of total demand, according to the Silver Institute. Gold demand comes mainly from jewellery, investment and central banks.
- Mines produce about seven times more silver than gold by weight: around 820 million ounces of silver and around 3,660 tonnes of gold in 2024. Yet the market ratio has rarely been close to 7.
- The average depends on the period you choose. Since 1971 the ratio has seldom stayed at one level for long.
- A high ratio can stay high for years. In much of the 1990s and the 2010s it was above 60–70.
How to track it in practice
- Use spot prices for both metals taken at the same moment.
- Look at a long period, at least 10–20 years. A single number without history tells you little.
- Compare real dealer buy and sell prices, not just spot. The spread on silver is what decides your outcome.
- Work out the costs in advance. Our gold calculator shows what a given weight of metal is worth.
- Keep records of the date, quantity and price of every purchase and sale for your tax return.
Bottom line
The gold/silver ratio is the gold price divided by the silver price. It has ranged from about 15 under 19th-century laws to above 120 in March 2020. Some investors use it to choose between the two metals or to switch between them, but in the UK the 20% VAT on silver and wider spreads greatly reduce the benefit of switching physical metal.

Frequently asked questions
What is the gold/silver ratio?
It is the price of one ounce of gold divided by the price of one ounce of silver. It shows how many ounces of silver one ounce of gold would buy.
What is a normal gold/silver ratio?
There is no fixed normal level. In the 19th century laws set it at about 15, while since 1971 it has ranged from about 17 in 1980 to above 120 in March 2020.
Does switching gold for silver make sense in the UK?
Silver bought for delivery carries 20% VAT that is not refunded, and its spreads are wider. The ratio therefore has to move a long way before a switch yields more metal.
Does the currency affect the ratio?
No. When both prices are in the same currency the exchange rate cancels out, so the ratio is the same in pounds and in dollars.
