Jaccard Similarity Calculator
Find set intersection size divided by set union size.
Open toolSet Calculator
Find union, intersection, first-set difference and symmetric difference for several sets. Provide Sets: one set per line to compute results directly in your browser. Elements are case-sensitive strings. Output preserves first-seen order. For three or more sets, symmetric difference includes elements belonging to an odd number of sets; first-set difference removes elements found in any later set.

How the Set Calculator Works & Core Formula
The Set Calculator evaluates Sets: one set per line in client-side JavaScript using the deterministic rule below and updates the output panel immediately without uploading data to a server.
Find union, intersection, first-set difference and symmetric difference for several sets.
Elements are case-sensitive strings. Output preserves first-seen order. For three or more sets, symmetric difference includes elements belonging to an odd number of sets; first-set difference removes elements found in any later set.
Set Calculator Quick Reference & Input Guide
Review the input parameters, allowed value ranges, and worked reference cases for the Set Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Sets: one set per line | a,b,c b,c,d | Use 2-20 lines, comma-separated string elements. Spaces around elements are removed; empty elements are ignored. Up to 1,000 distinct elements per set. | Required workspace parameter |
| Worked Case 1: Baseline run (Sets: one set per line = a,b,c b,c,d) | Preloaded / test values | Find union, intersection, first-set difference and symmetric difference for several sets | Sets: one set per line = a,b,c b,c,d. Output: Union: a, b, c, d; Intersection: b, c; First set minus the others: a; Symmetric difference (odd membership): a, d. |
| Worked Case 2: Comparison scenario (set calculator math) | Preloaded / test values | Find union, intersection, first-set difference and symmetric difference for several sets | Sets: one set per line = 1,2 2,3 3,4. Output: Union: 1, 2, 3, 4; Intersection: ∅; First set minus the others: 1; Symmetric difference (odd membership): 1, 4. |
Step-by-Step Guide to Using the Set Calculator
Follow these three steps to configure Sets: one set per line, verify unit and boundary rules, and export your Set Calculator output.
Enter the inputs
Start with sets: one set per line. Use 2–20 lines, comma-separated string elements. Spaces around elements are removed; empty elements are ignored. Up to 1,000 distinct elements per set.
Input and settings

Practical Worked Examples for Set Calculator
These concrete scenarios illustrate how the Set Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Sets: one set per line = a,b,c b,c,d)
Sets: one set per line = a,b,c b,c,d. Output: Union: a, b, c, d; Intersection: b, c; First set minus the others: a; Symmetric difference (odd membership): a, d.
Comparison scenario (set calculator math)
Sets: one set per line = 1,2 2,3 3,4. Output: Union: 1, 2, 3, 4; Intersection: ∅; First set minus the others: 1; Symmetric difference (odd membership): 1, 4.
Boundary & unit check (Set Calculator)
When solving for 'set calculator', verify that Sets: one set per line use consistent units and stay within the documented scope: Elements are case-sensitive strings. Output preserves first-seen order. For three or more sets, symmetric difference includes elements belonging to an odd number of sets; first-set difference removes elements found in any later set.
How to Read and Verify the Set Calculator Output
The output panel reports the exact result derived from Sets: one set per line alongside any unit or formatting notes.
Every calculation follows the rule: Find union, intersection, first-set difference and symmetric difference for several sets. Because JavaScript uses IEEE 754 double-precision floating-point arithmetic, numeric outputs display up to 12 significant digits where applicable.
Always cross-check the displayed result against the scope note (Elements are case-sensitive strings. Output preserves first-seen order. For three or more sets, symmetric difference includes elements belonging to an odd number of sets; first-set difference removes elements found in any later set) before applying the value to production specifications, financial models, or lab records.
Scope Limits, Accuracy Assumptions & Related Everyday Math Tools
Review these boundary constraints and validation rules before relying on the Set Calculator output.
Operational scope: Elements are case-sensitive strings. Output preserves first-seen order. For three or more sets, symmetric difference includes elements belonging to an odd number of sets; first-set difference removes elements found in any later set. Inputs that violate minimum/maximum bounds or required format rules are rejected with a clear diagnostic prompt.
