Number Sum Calculator

About the Number Sum Calculator

We created this Number Sum Calculator as a fast and easy way to add up numbers from any text. You can just copy and paste a list of numbers, and we'll handle the rest. The tool is smart enough to find all the numbers in your text and ignore any words, symbols, or other characters, so you don't have to clean up your list first.

As soon as you paste your data, the tool instantly calculates not just the total sum, but also other useful statistics like the count of numbers, the average, the smallest and largest values, and the median. It's a handy utility for anyone who needs to quickly analyze a set of numbers without any fuss.

How to Use the Tool

• Paste your list of numbers into the text area. The numbers can be separated by anything: commas, spaces, new lines, or even mixed with text.
• The statistics in the panel below will update in real-time as you type or paste.
• You can find the total sum, count, average, min, max, and median values.
• Use the buttons to load a sample, open a file, copy the results, or clear the input to start over.

Frequently Asked Questions

What kind of numbers can this tool calculate?

Our calculator is built to be robust. It correctly handles positive numbers, negative numbers, and numbers with decimal points. It automatically extracts these values from whatever text you provide.

What happens if my text has words or symbols in it?

The tool is designed to ignore them. It will intelligently parse your text, find only the valid numbers, and use them for the calculation. This means you can paste directly from spreadsheets, documents, or websites without needing to clean up the data first.

What do all the statistics mean?

The results panel gives you a comprehensive breakdown of your number list:

• Sum: The total when all the numbers are added together.
• Count: The total quantity of numbers found in your text.
• Average: The mean value of all the numbers (the sum divided by the count).
• Min / Max: The smallest and largest numbers in the list.
• Median: The middle value of the list after it has been sorted. This is often a better indicator of the "center" than the average.

Is the data I enter private?
