How the online counter works
An online counter is a free tool that runs in your browser and adds or subtracts a number each time you press a button or a key. Use plus and minus to change the count by your chosen step, or use the quick buttons for +1, +10, −1, and −10. Reset returns to your starting number. Type a starting value and press Set to begin somewhere else. The tool accepts very large positive and negative whole numbers.
Count by 1, 5, 10, 25, 100, or enter any positive whole number. Undo reverses the last change. On a keyboard, Space or Arrow Up increases, Arrow Down decreases, R resets, and Ctrl or Cmd + Z undoes. Your count is saved in this browser so it is still there after you refresh. Nothing is sent to a server.
How to use the online counter
- Open this page. The counter is ready at the top — there is nothing to install and no account to create.
- Choose a step. Leave it at 1 for one-by-one counting, or choose 5, 10, 25, or 100, or type a custom step.
- Press + or Space to add. Press − or Arrow Down to subtract if you counted one too many.
- To start from a different number, type it in the starting-number box and press Set.
- Press Reset to return to your starting number. Press Undo, or Ctrl or Cmd + Z, to reverse the last change.
- Close the tab and come back later. Your count is saved in this browser on this device.
What can you count?
People use an online counter for anything that arrives one at a time: people through a door, attendance, laps, repetitions, cars in a survey, stock on a shelf, votes, and items packed in a box.
- People and attendance: count people in, count people out, and keep a running total for a room, a queue, or a gate.
- Sport and exercise: count laps, sets, repetitions, goals, and points without a paper score sheet.
- Work and stock: count items packed, items checked, calls made, and parts counted during an inventory check.
Why use an online counter instead of paper?
Paper tally marks work, but they are easy to lose, hard to read in low light, and hard to correct. An online counter keeps one clear number on the screen, lets you undo a mistake in one press, and remembers the total after a refresh.
Online counter, tally counter, and click counter — what is the difference?
These names describe the same basic job from different angles. An online counter is the general name for a counter in a browser. A tally counter is for one mark per person, item, or event, shown as tally marks. A click counter is for counting mouse clicks and touchscreen taps themselves. A number counter is for raising or lowering a numerical total by a custom step. A digital counter shows a large digital count that is easy to read at a glance. A button counter uses one large plus button for quick manual counting. An online counting machine is a simple running count in the browser, shown like an odometer. Choose the page that matches what you are counting, or start here and use the general counter.
| What you need | Use this page | When not to use it |
|---|---|---|
| A general running count | online counter | When you need tally marks on paper — this page shows a number, not a paper sheet. |
| One mark per person or event | tally counter | It does not scan barcodes, count coins, or store records on a server. |
| Count clicks or taps themselves | click counter | It does not monitor clicks on other websites. |
| A total you raise or lower by a step | number counter | It does not save the total to a server or share it with another device. |
| A large count to read from a distance | digital counter | It is a webpage, not a physical digital counter. |
| One large button to press quickly | button counter | It does not count automatically — you press for each count. |
| A simple running count like a machine | online counting machine | It does not count money or parts on a production line. |
Does the count save? Is it private?
Yes, the count is saved in this browser, using local storage on your own device. If you refresh the page, the count is still there. If you clear your browser data, or use a different browser or a different device, the count starts again, because nothing is sent to a server and there is no account to sync it.

What is the difference between this and a tally counter?
