How this calculator works
This page illustrates the traditional 4 mL/kg/%TBSA Parkland formula. The first phase starts at injury, not hospital arrival. The current ABA adult burn-shock guideline recommends starting at 2 mL/kg/%TBSA for adults with burns of at least 20% TBSA, with clinical titration. The displayed Parkland estimate is therefore not a current default prescription. Enter a professionally assessed partial- and full-thickness area; superficial burns are excluded. The result is an estimate for information only and is not medical advice.
Formula
Traditional 24-hour volume (mL) = 4 × weight (kg) × burned TBSA in percentage points. Half falls in the first 8 hours after injury and half in the following 16 hours.
Worked example
70 kg and 30% TBSA give 8400 mL in the traditional model. Each phase contains 4200 mL, averaging 525 mL/h initially and 262.5 mL/h subsequently.

Frequently asked questions
Can I choose affected body parts?
This page takes a directly assessed TBSA percentage. It does not implement age-dependent Lund-Browder diagrams or infer burn depth.
Does it cover paediatric maintenance fluid?
No. Children require a separate assessed resuscitation and maintenance plan. This arithmetic alone is insufficient.
Can I use the first-phase average after a delayed arrival?
No. It assumes the full eight-hour phase and does not account for elapsed time or fluids already given.
