How to use Find the Running Total
- 1. Paste your integers in order. Enter the sequence of integers in the order you want summed, since each running total depends on everything that came before it.
- 2. Choose a separator. Set Separator to control how the resulting running-total values are joined together, such as a comma or newline, to match what you need next.
- 3. Read the running totals. The tool adds terms one at a time and outputs the prefix sum after each addition, ending with the sum of the entire sequence.
- 4. Copy the results. Copy the full list of running totals from the output pane and paste it into a spreadsheet, chart or report.
When to use Find the Running Total
Find the Running Total shows the prefix sum after each number in a sequence, revealing how a total builds up rather than just the final answer. Use Find the Running Total whenever you need to see the trajectory of accumulation, not just the endpoint.
- Tracking a cumulative budget. You have a list of daily expenses as whole dollar amounts and want to see the running balance after each day, not just the month's total.
- Charting cumulative sales. A spreadsheet has daily unit sales and you want a cumulative-sales column to feed into a running-total chart for a monthly report.
- Verifying a prefix-sum algorithm. You are testing code that computes prefix sums and need a trusted reference sequence to check your implementation against, value by value.
- Explaining accumulation in a lesson. A math lesson on sequences needs a worked example showing how partial sums grow term by term. Generate the running totals to use as the answer key.

About the Find the Running Total tool
Find the Running Total does its work locally, right in the browser. Calculate the partial sum of a bunch of integers. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Integer Tools collection on EditSafely, a set of 133 small, focused Integer utilities that share the same instant, private workspace.
You can shape the output with the Separator setting, and the result refreshes the moment you change it. 2 worked examples further down the page show exactly what the tool produces for real inputs.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Find the Running Total free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
