FLACC scale calculator.
Add the scores for face, legs, activity, cry and consolability. Enter each value from your FLACC assessment reference to calculate a total out of 10.
This calculator adds scores you have already assigned using the appropriate FLACC instrument. It does not reproduce the behavioural scoring criteria or implement revised FLACC (r-FLACC).

Not assessed yet? Leave the component unselected. A value of 0 is a recorded score, not a placeholder for a missing assessment.

FLACC and Glasgow
FLACC is an observational measure of pain-related behaviour. It is distinct from Glasgow, which describes responses used to assess consciousness.
Open Glasgow calculator →Who is standard FLACC intended for?
The Royal Children’s Hospital acute pain guideline lists standard FLACC for children aged 2 months to 7 years. It lists revised FLACC separately for non-verbal children with developmental disability or cognitive impairment. Choose the appropriate tool with a healthcare professional.
What is the difference between FLACC and r-FLACC?
Revised FLACC incorporates additional and individualised behaviours for children with cognitive impairment. This page is a standard FLACC score-entry aid and does not include an r-FLACC assessment.
Does 0/10 mean that pain is absent?
A score of 0 reflects the component scores entered for that observation. Behaviour, communication ability and the surrounding circumstances must be considered; the result alone cannot rule pain out.
Can this calculator assign the component scores for me?
No. Assign each component using the applicable assessment reference. This page only calculates the sum and prepares a copyable or printable breakdown.

FLACC scale: components, examples and scope
The five entries above are scores from an assessment you have already completed. The following guide helps you check the arithmetic, keep the two C components separate and understand what this score-entry tool can report.
What is the FLACC scale?
FLACC is an observational approach to pain-related behaviour. Its name comes from Face, Legs, Activity, Cry and Consolability. It is not a request for the person to select their own pain intensity. The University of Michigan resource describes the instrument and its use.
The calculator handles the numerical part of an existing assessment. It cannot observe behaviour, select the appropriate instrument or establish why someone is distressed. There are no behavioural descriptors behind the numeric buttons: consult the original assessment to assign the component values before using them here.
What do the five entries mean?
Each component accepts 0, 1 or 2. The sum ranges from 0 to 10 after all five entries have been completed. In the report, Cr means Cry and Co means Consolability. This avoids using an ambiguous C for two different categories.
| Component | Allowed values |
|---|---|
| F · Face | 0, 1, 2 |
| L · Legs | 0, 1, 2 |
| A · Activity | 0, 1, 2 |
| Cr · Cry | 0, 1, 2 |
| Co · Consolability | 0, 1, 2 |
Formula: FLACC = F + L + A + Cr + Co. Each value contributes directly to the sum; there are no additional multipliers. A blank category does not become zero automatically. You must explicitly enter 0 when that is the score established by the assessment.
Entering and checking a score
- Confirm that you are using the standard FLACC instrument appropriate to the assessment context.
- Read the already assigned value for each category from your assessment reference.
- Select one value in all five rows, taking particular care with Cry and Consolability.
- Compare the five-item breakdown against the source entry, then copy or print the result.
You may change a category by choosing another value in the same row. Reset clears the entire form. The counter shows how many categories have an entry, not how many observations have been validated. The calculator checks allowed numbers and completeness; it does not check how the observations were obtained.
Worked FLACC calculations
The examples below are numerical exercises. The category values are supplied rather than derived from a description of a child.
| Exercise | Entered values | Result |
|---|---|---|
| Example 1 | 0 + 0 + 0 + 0 + 0 | 0/10 |
| Example 2 | 1 + 0 + 1 + 2 + 0 | 4/10 |
| Example 3 | 2 + 2 + 2 + 2 + 2 | 10/10 |
| Example 4 | 0 + 0 + 0 + 0 + — | No total |
For the 4/10 example, changing Consolability from 0 to 2 while leaving the other four values unchanged produces 6/10. Changing Cry is a separate operation. A complete sequence of five zeros is a valid numerical entry. Four zeros and a blank field remain incomplete and do not produce a total.
Interpreting the number without overstating it
A behavioural score and a self-reported pain intensity rating represent different forms of information. They should not be treated as interchangeable just because both can use a 0–10 range. The surrounding circumstances matter when a professional interprets the observation.
This page reports the sum and components without attaching a treatment recommendation. It does not identify the cause of pain or prescribe medication. When comparing two entries, keep the instrument, the five values and the observation context available. The tool does not store those observations or decide whether a change between them is clinically meaningful.
Standard FLACC, age range and revised FLACC
The RCH acute pain guideline lists standard FLACC for children aged 2 months to 7 years and presents revised FLACC separately for non-verbal children with developmental disability or cognitive impairment. That is the scope of the cited guideline, not a universal rule covering every validated use.
The revised FLACC study describes a modified approach for children with cognitive impairment. This page does not implement that revised instrument. Translating interface labels into Spanish does not create a validated Spanish assessment. Check the required instrument and language version independently before assigning any scores.
Reporting, references and frequent mistakes
Retain all five values when copying a result. For example, “F1 · L0 · A1 · Cr2 · Co0 = 4/10” identifies the calculation more clearly than “pain 4”. Do not describe the copied text as a self-report supplied by the person being assessed: that is not what the tool records.
Common input errors include entering zero for an unassessed category, swapping the two C entries and carrying a previous selection into a new exercise. Review the component counter and reset between examples. The source links below lead to the original instrument information; the browser’s print button produces only your numerical summary.
