Assuming you are using SQL and you have a table named 'expenses' with columns 'category' and 'amount', you can use the following query:

```sql
SELECT category, SUM(amount) as total_amount
FROM expenses
GROUP BY category;
```

Here's the step by step explanation:

1. `SELECT category, SUM(amount) as total_amount`: This line is selecting the 'category' column and the sum of the 'amount' column for each category. The `SUM(amount)` function adds up all the values in the 'amount' column. The `as total_amount` part is renaming the column for the sum of the amount to 'total_amount'.

2. `FROM expenses`: This line is specifying the table where the data is coming from, which in this case is the 'expenses' table.

3. `GROUP BY category`: This line is grouping the selected columns by 'category'. This means that the output will have a row for each category, and the 'total_amount' will be the sum of the 'amount' for each category.
