Every balance is earnings minus payments
- The balance on any component is what the country earns from selling abroad minus what it pays for buying from abroad.
- A positive answer is a surplus on that component and a negative answer is a deficit.
- Put every figure into the same units before you start, because mixing millions with billions is the fastest way to a wrong answer.
- Write the earnings figure first and the payments figure second, then subtract, and the sign comes out right on its own.
Working the real UK trade figures for 2025
- The UK bought far more goods from abroad than it sold, but sold far more services abroad than it bought, which is its long-standing pattern.
- Those two component balances combine into the overall balance on trade.
Example
- In 2025 the UK had a deficit of £221 billion on trade in goods and a surplus of £203 billion on trade in services.
Step 1: write the two balances down with their signs:
trade in goods balance=−£221bn \text{trade in goods balance} = -\pounds221\text{bn} trade in goods balance=−£221bn trade in services balance=+£203bn \text{trade in services balance} = +\pounds203\text{bn} trade in services balance=+£203bnStep 2: subtract the goods deficit from the services surplus to find the overall trade balance:
trade balance=£203bn−£221bn=−£18bn \text{trade balance} = \pounds203\text{bn} - \pounds221\text{bn} = -\pounds18\text{bn} trade balance=£203bn−£221bn=−£18bn- The answer is negative, so the UK ran an overall trade deficit of £18 billion in 2025.
- The services surplus offset most of the goods deficit but not all of it, which is why the shortfall is far smaller than the goods figure alone suggests.
Adding four balances gives the current account
- Trade is only two of the four components, so the current account balance is the sum of all four, including primary and secondary income.
- Income balances are usually much smaller than trade balances, but they are frequently negative for the UK, so leaving them out flatters the answer.
- The two income figures used below are round illustrative numbers, chosen only to show how the four balances combine.
Example
- Start from the 2025 trade balance of minus £18 billion, and add an illustrative primary income deficit of £10 billion and an illustrative secondary income deficit of £30 billion.
Step 1: add the primary income balance to the trade balance:
trade and primary income=−£18bn−£10bn=−£28bn \text{trade and primary income} = -\pounds18\text{bn} - \pounds10\text{bn} = -\pounds28\text{bn} trade and primary income=−£18bn−£10bn=−£28bnStep 2: add the secondary income balance to reach the current account:
current account balance=−£28bn−£30bn=−£58bn \text{current account balance} = -\pounds28\text{bn} - \pounds30\text{bn} = -\pounds58\text{bn} current account balance=−£28bn−£30bn=−£58bnStep 3: check the total against all four components in one line:
current account balance=−£221bn+£203bn−£10bn−£30bn=−£58bn \text{current account balance} = -\pounds221\text{bn} + \pounds203\text{bn} - \pounds10\text{bn} - \pounds30\text{bn} = -\pounds58\text{bn} current account balance=−£221bn+£203bn−£10bn−£30bn=−£58bn- The total is negative, so on these figures the current account is in deficit by £58 billion.
Signs and units decide whether an answer works
- Carry the sign and the units to the final line, so the answer reads as minus £58 billion rather than a bare 58.
- Adding a negative balance is the same as subtracting its size, which is where most slips happen when four components are combined.
- Check the direction of the answer against the numbers before writing it, since one large surplus can outweigh several small deficits.
Common Mistake
- A surplus on one component tells you nothing about the total, so never report a single line as though it were the current account.
- Read the question to see whether it wants one component balance or the whole current account, because the two answers differ by the income components.
Self review
- Write the rule for finding the balance on trade in goods.
- A country has a goods deficit of £221 billion and a services surplus of £203 billion. What is its overall trade balance?
- Which two components have to be added to the trade balance to reach the current account balance?
- A component balance comes out at minus £30 billion. Is that a surplus or a deficit?
- Why is a calculated balance incomplete without a sentence of interpretation?
