The use of formula's and the uses of the spreadsheet are able to cut much time for many people. Its ability to be able to sub in and out changes makes it easier to do multiple changes without having to redo many of the calculations.

Also its ability to be able to fill in (Dragging down a column to fill.) makes it very time efficient.

The function of being able to rename a box or boxes can actually be extremely helpful when filling in formula's, instead of having to scroll halfway accross your spreadsheet to find the box or boxes your looking for.

To conclude in a simple manner, spreadsheets in a computer context are able to make organisation, marks etc. much more time efficient, without much chance of calculating error, without a major stuff up on the human side.
