What Online Amount Splitter does
Split a total amount into multiple parts while preserving the total
Worked example
Input
Total 100; weights 1, 2, 3
Result
16.67, 33.33, 50.00
Calculation rule
Each weight receives total × weight ÷ sum of weights. Rounding is reconciled so the displayed parts still add back to the original total.
Practical uses
- Check a small calculation before applying the same rule to a longer list.
- Prepare normalized numeric data for a spreadsheet, report or test fixture.
- Compare the copied result with the displayed input count and options.
Limits and review checks
- Confirm decimal separators, signs, leading zeros and inclusive boundaries before relying on the output.
- Very large lists or exhaustive permutations can consume substantial browser memory.
- Floating-point decimals and rounded shares may differ by a final displayed unit; review the shown precision.
Frequently asked questions
Are my numbers uploaded?
No. This tool performs its normal parsing and calculation in your current browser.
Why can another calculator show a different result?
Check parsing rules, rounding precision, population versus sample settings, boundary inclusion and whether duplicate values are retained.
