What this burn calculator does

This free burn calculator helps clinicians and learners estimate total body surface area burned (%TBSA) and calculate an initial fluid plan using common approaches such as the Parkland formula. It supports age‑adjusted mapping (Lund–Browder for pediatric and adult) and a quick adult Rule of Nines mode. You can print a summary or export a PNG of the body map.

How to use the calculator

  1. Enter age, gender, and weight (kg or lb).
  2. Click the body map to mark burned regions and cycle depth: Partial → Full → Off. Use macros for common areas.
  3. (Optional) Add an inhalation-injury modifier and subtract any pre-hospital fluids given.
  4. (Optional) Enter time of injury to see an estimated mL/hr plan for the first 8 hours.
  5. Print the result or copy the summary for documentation.

How %TBSA is estimated

Lund–Browder tables adjust for age (head and lower-limb proportions change from infancy to adulthood). For a fast adult estimate, the Rule of Nines assigns standard percentages to large body regions. This tool lets you switch between both approaches.

Fluid resuscitation overview (Parkland)

A commonly taught starting point is the Parkland formula: 4 mL × weight(kg) × %TBSA for the first 24 hours. Typical teaching suggests half in the first 8 hours from time of injury, and the remainder over the next 16 hours. This calculator displays volumes in mL and liters, and shows a simple rate plan when time of injury is provided.

Pediatric considerations

Pediatric TBSA estimates differ from adult values; Lund–Browder curves account for larger head and smaller lower-limb proportions in infants and children. Maintenance fluids (e.g., Holliday–Segar) are shown separately when toggled for patients under 18 years. Always follow local pediatric burn protocols and consult specialists.

Inhalation injury

Inhalation injury can increase fluid requirements and is associated with additional risks. The optional modifier in this calculator is for illustration only. Use institutional guidance and clinical judgment; advanced airway and critical-care considerations may apply.

FAQ

Is this calculator a substitute for clinical judgment?

No. This tool is for education and documentation support only. Always follow local guidelines and consult burn specialists when needed.

Which TBSA method should I use: Lund–Browder or Rule of Nines?

Use age‑adjusted Lund–Browder for better accuracy—especially in children. Rule of Nines is acceptable for a rapid adult estimate in emergencies.

Does the Parkland formula apply to chemical or electrical burns?

Some burn types (chemical, electrical) and associated injuries may require different approaches. Follow your local protocol and specialist advice.

Can I print or export the map?

Yes. Use the Print/PDF button for a clean report, or export a PNG of the annotated body map when available.

Is pediatric maintenance fluid included?

Yes—an optional Holliday–Segar panel appears for patients <18 years. It is shown alongside Parkland for reference.
