I have a spreadsheet with values that are categorized, for instance:

Name - Category - Value
lunch - food - 20
fuel - transportation - 100
dinner - food - 20
repairs - transportation - 200

Let's assume these values are in A1 to C5 - so your values are in rows 2 to 5.

Then I would like to have a sum of values for each category, such as:

food - 40
transportation - 300

Let's put these two categories in column E - in E1 and E2.

Can anyone help with functions to make this "per category sum"?

One way to do this is to put in F1:

If instead you put:
you can even fill it down column F into F2, giving

Another technique is to put in F1:
or, again,
so you can fill this down into F2.

How does this second method work? Well, the test of equality gives a value which can be interpreted as a number: 1 for TRUE and 0 for FALSE. Multiplying this by your "value" switches each value on or off in the sum.

I trust this helps.
