Enter serum albumin, current weight, and usual weight to quickly calculate your NRI score, assess nutritional status, and identify malnutrition risk levels.
Enter data to assess nutritional status.
Calculation Formula: NRI = (1.519 × Albumin g/L) + 41.7 × (Current Weight / Usual Weight). If current weight > usual weight, the weight ratio is taken as 1.

When experiencing abnormal weight loss or low serum albumin levels, the Nutritional Risk Index (NRI) can objectively quantify your risk of malnutrition. This tool calculates your NRI score using the standard formula: [1.519 × serum albumin (g/L)] + [41.7 × (current weight / usual weight)]. It then outputs a nutritional status classification (none / mild / moderate / severe malnutrition). Serum albumin is a core indicator of serum proteins, reflecting the body's nutritional reserves.
The input range for serum albumin is 0-100 g/L, and the weight range is 10-200 kg. "Usual weight" refers to your stable weight over the past six months. Calculation results are for reference only; medical decisions require a comprehensive assessment by a professional dietitian.
Clinical recommendation: When NRI < 97.5, a comprehensive assessment combining indicators like transferrin should be conducted. Typical example: With a serum albumin of 42 g/L, current weight of 60 kg, and usual weight of 70 kg, the NRI is 95.3, indicating mild malnutrition. Regular monitoring can detect weight loss trends; monthly follow-ups are recommended for high-risk groups.
