Target Sum Finder
Which amounts add up to your total? Paste a list and find the matching lines, including repeated amounts and negative adjustments.
Paste up to 20 amounts, one per line. Each line can be used once in a combination.
How the matching works
Can a line be used more than once?
Each source line is used at most once within each combination. Two lines containing 10.00 are two separate entries: both can match a target of 20.00. The same line may appear in different alternative combinations.
Are decimals and negative amounts supported?
Yes. Amounts are matched exactly to two decimal places, including negative amounts and zero. Use a single currency, a decimal point, and no currency symbols or grouping separators. The target and the sum of absolute input amounts must each be within 90,071,992,547,409.91 in magnitude.
Will I see every match?
The tool accepts up to 20 non-empty lines and displays up to 50 combinations. If more exist, the result says the list is incomplete. If the search times out, any matches found are partial results, and no conclusion about unmatched amounts is made. A completed search with no results means no non-empty subset exactly matches the target.
Is this the same as a combination sum calculator?
This tool finds subsets of your actual entries, with each line used once. Some combination sum problems allow a value to be reused without limit; that mode is not supported here. Read the guide to combination sums and amount matching for examples.
Where do my amounts go?
The matching runs in your browser. This tool does not upload amounts or store them in calculation history. Copying results uses your device clipboard.
