Apgar Score Calculator
Compute a newborn’s Apgar score from the five clinical components and classify it using the AAP/ACOG bands used in delivery rooms worldwide.
Apgar score — Reassuring

- A — Appearance

- P — Pulse
- 2 / 2
- G — Grimace
- 2 / 2
- A — Activity
- 2 / 2
- R — Respiration
- 2 / 2
The Apgar score is the sum of five components (Appearance, Pulse, Grimace, Activity, Respiration), each rated 0, 1, or 2, for a total of 0–10. It is assessed at 1 and 5 minutes after birth (and every 5 minutes thereafter up to 20 minutes if the 5-minute score is below 7). Bands: 7–10 reassuring, 4–6 moderately abnormal, 0–3 low.

How to use this calculator
For each of the five Apgar components — Appearance, Pulse, Grimace, Activity, Respiration — choose the score (0, 1, or 2) that best matches the infant. The calculator returns the total Apgar score (0–10), shows each component, and labels the result with the standard AAP/ACOG interpretation band.
How the calculation works
The Apgar score, introduced by Dr Virginia Apgar in 1952 and standardised internationally, is the sum of five components, each rated 0–2: Appearance (skin colour), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration (breathing effort). The total ranges from 0 to 10. AAP/ACOG Committee Opinion No. 644 — reaffirmed in 2020 — defines the interpretation bands: 7–10 is reassuring, 4–6 is moderately abnormal, and 0–3 is low and prompts immediate resuscitation. Scores are recorded at 1 minute (reflects intrapartum status) and 5 minutes (reflects response to resuscitation); when the 5-minute score is below 7 it is repeated every 5 minutes up to 20 minutes. The Apgar score is descriptive — not predictive of long-term outcome — and should never be used in isolation to diagnose birth asphyxia.
Worked example
A neonate at 1 minute is pink on the body but blue at the hands and feet (Appearance = 1), has a heart rate of 130 bpm (Pulse = 2), grimaces to suction (Grimace = 1), shows some flexion of the arms and legs (Activity = 1), and has a weak, irregular cry (Respiration = 1). The total is 1 + 2 + 1 + 1 + 1 = 6, which falls in the 4–6 band — moderately abnormal. The clinician dries, stimulates, and reassesses at 5 minutes. If the 5-minute score is then 9 (active, pink, strong cry, HR 140), the infant is now in the reassuring 7–10 band and routine care continues.
Frequently asked questions
What does Apgar stand for?
Apgar is both the surname of Dr Virginia Apgar — the anaesthesiologist who introduced the score in 1952 — and a mnemonic for the five components: A for Appearance (skin colour), P for Pulse (heart rate), G for Grimace (reflex irritability), A for Activity (muscle tone), and R for Respiration (breathing effort). Each is scored 0, 1, or 2.
When is the Apgar score taken?
The Apgar score is assessed at 1 minute and 5 minutes after birth. The 1-minute score reflects the infant's intrapartum status and the 5-minute score reflects response to resuscitation. If the 5-minute score is below 7, AAP/ACOG recommend repeating the score every 5 minutes up to 20 minutes, recorded alongside the resuscitative measures being given.
What is a normal Apgar score?
A 5-minute Apgar score of 7 to 10 is considered reassuring. Scores of 4 to 6 are moderately abnormal and warrant continued stimulation or assisted ventilation. Scores of 0 to 3 are low and require immediate, full resuscitation. A 1-minute score below 7 is common in healthy neonates who simply need a few seconds longer to transition and is not in itself worrying if the 5-minute score recovers to 7 or above.
Does a low Apgar score mean the baby has brain damage?
No. AAP/ACOG explicitly state that the Apgar score alone is not a predictor of neurological outcome. A low score has many causes — prematurity, maternal sedation, congenital malformations, transient cardiopulmonary depression — and most infants with a low 1-minute score recover fully. Birth asphyxia requires a combination of findings: low Apgar persisting beyond 5 minutes, severe metabolic acidosis on cord-blood gas, early neonatal encephalopathy, and multisystem organ involvement.
How is the Apgar score different from cord-blood gas analysis?
The Apgar score is a rapid clinical observation that captures the infant's state at a moment in time. Cord-blood gas analysis measures the pH and base deficit of arterial or venous cord blood and gives an objective picture of intrapartum acid-base status. The two complement each other: the Apgar tells you what the baby looks like now, the cord gas tells you what the labour did to the baby chemically. AAP/ACOG recommend recording both whenever an intrapartum event is suspected.
Is the Apgar score used differently for premature babies?
Yes — with caution. Premature infants score lower simply because tone, reflexes, and respiratory effort are immature; a low Apgar in a preterm infant does not have the same meaning as it does in a term infant. The expanded Apgar score, recommended by AAP/ACOG, additionally records the resuscitative interventions in progress (oxygen, positive pressure ventilation, intubation, chest compressions, adrenaline) so the score can be interpreted alongside the support being given.
Can a parent calculate their own baby's Apgar score?
Apgar is intended for clinicians. Several of its components (heart rate, response to suction stimulation) are difficult to assess accurately without training. Parents seeing this calculator typically want to understand a number they were given in the delivery room — a score of 9 at 5 minutes, for example, is entirely normal because the 1 in Appearance is almost always lost to peripheral blueness that has not yet resolved.
Is the Apgar score a substitute for clinical judgement?
No. This calculator implements the AAP/ACOG scoring rules accurately but cannot substitute for a clinician at the bedside. The score is one part of neonatal assessment alongside heart-rate monitoring, oxygen-saturation measurement, cord-blood gas analysis, and the clinical context of the labour. Any infant with concerning findings needs hands-on assessment and, where indicated, the Neonatal Resuscitation Program algorithm — regardless of the Apgar number.
