Sum Calculator

Paste any block of text containing numbers and the calculator instantly extracts every number it finds, then adds them all up. It handles messy input like receipts, bank statements, copied spreadsheet columns, or even paragraphs with numbers scattered throughout. You do not need to clean up your data first.

The tool scans your input for valid numbers, ignoring letters, symbols, and formatting. It recognises decimals, negative numbers, and comma-separated thousands (like 1,250). Once extracted, it calculates the sum, average, minimum, maximum, and count of all detected values.

The most common use is adding up a list of numbers without opening a spreadsheet. Paste a column of figures from a receipt, invoice, or bank statement and get an instant total. It is also useful for totalling scores, survey responses, or any data you have copied from a website or document.

Compared to a spreadsheet, this tool requires zero setup. There are no cells to format, no formulas to write, and no file to save. Paste your numbers, see the result. It is ideal for one-off calculations where opening Excel or Google Sheets would be overkill.
