Adjusting a number, not keeping a tally
A number counter is for when the figure on screen is the work: remaining items, a score that can go down, a total you picked up mid-count, or a step size other than one. The tally counter is built around marking occurrences. This page is built around moving a number.
You can use positive and negative whole numbers, set a starting value, and count by 1, 5, 10, 25, 100, or any positive whole number. Very large values are allowed. The total stays in this browser; it is not a spreadsheet or a calculator with formulas.
When to use a number counter
- Increasing a total as quantities are added
- Decreasing a total as quantities are used or removed
- Starting from a number you already have
- Stepping by 5, 10, or another custom increment
- Working with negative values
- Keeping a very large whole-number total readable
How to change the total
- Enter a starting number and press Set, or leave it at zero.
- Choose Count by if each press should move more than 1.
- Use + to increase and − to decrease.
- Undo reverses the last change. Reset returns to the starting number.
Frequently asked questions
Can the number be negative?
Yes. Decrease below zero, or Set a negative starting number.
How large can the number be?
Whole numbers can be far larger than ordinary calculator displays. Enter them as digits; commas in the starting field are ignored.
Can I count down as well as up?
Yes. Minus subtracts the current increment, so remaining quantities can fall as you work.
