Frequently Asked Questions

What is a running total?

It is the sum built up step by step. Each line adds the next number to the total so far, so you can see how the sum grows.

Does it work with decimals and negatives?

Yes. Numbers are added as values, so decimals and negatives are handled correctly, and a negative simply lowers the running total.

What is the last line?

The last line is the grand total, the sum of all the numbers you entered.

What happens to invalid lines?

Lines that are not numbers are ignored, so they do not break the running total.

Is my data uploaded?

No. The calculation runs in your browser and your numbers never leave the tab.
