Sum Calculator
Summation Calculator & Number Adder
What is Sum Calculator?
This calculator turns messy lists of values into clear, trustworthy results in seconds. Paste numbers separated by commas, spaces, tabs, semicolons, or new lines and press Calculate to immediately see the sum, count, average, minimum, maximum, and median. If you just need to add these numbers and confirm the headline total, it gets you there with zero setup.
It handles real-world input gracefully. The parser supports both decimal dot (12.34) and decimal comma (12,34), with an automatic detector plus a quick switch if your data needs an override. Non-numeric fragments are ignored, and the field shows a gentle hint when formatting issues are detected, so you know exactly what to fix. You can drop a TXT or CSV file straight in, copy the sum with one click, or export the cleaned values to CSV for reuse in other tools. Power users can recalculate from the keyboard while editing. Everything runs locally in your browser, so there’s no waiting and your data doesn’t leave the page.
Who benefits?
- Finance and operations: quick invoice checks, petty cash tallies, reconciliation, inventory totals.
- Analysts and marketers: fast sanity checks on exports, campaign results, or ad-hoc cohorts.
- Ecommerce and support teams: order totals, refund batches, SKU lists from spreadsheets.
- Researchers, educators, and students: lab readings, grade lists, survey responses.
- General use: anytime a report or email dumps values and you need to add these numbers, check a median, or move a cleaned list onward.
In short, it’s a focused utility for people who work with numbers but don’t want to open a full spreadsheet every time. When speed and clarity matter, paste, add these numbers, and take away a result you can trust.
