Calculate precise insulin doses for blood glucose correction and meal coverage using established medical formulas. Includes correction dose calculation using sensitivity factors and meal dose calculation using carbohydrate ratios.
Current Blood Glucose is required
Correction factor, total daily dose, or weight is required
Carbohydrates is required

Correction Dose:
Dose = (Current Glucose - Target Glucose) ÷ Correction Factor
Meal Dose:
Dose = Carbohydrates (g) ÷ Carb Ratio
Rule of 1700 (Correction Factor):
Correction Factor = 1700 ÷ Total Daily Dose
Rule of 450 (Carb Ratio):
Carb Ratio = 450 ÷ Total Daily Dose
Scenario: Current glucose 200 mg/dL, Target 100 mg/dL, TDD 50 units, Eating 60g carbs
Correction Factor: 1700 ÷ 50 = 34 mg/dL per unit
Correction Dose: (200 - 100) ÷ 34 = 2.9 units
Carb Ratio: 450 ÷ 50 = 9g per unit
Meal Dose: 60 ÷ 9 = 6.7 units
Total Dose: 2.9 + 6.7 = 9.6 units
Accurate insulin dosing is critical for diabetes management and preventing both short and long-term complications:
You can estimate it using the Rule of 1700: divide 1700 by your total daily insulin dose. Alternatively, provide your weight and the calculator will estimate your total daily dose first.
Use the Rule of 450: divide 450 by your total daily insulin dose. This gives you grams of carbohydrates covered by one unit of insulin. Work with your healthcare provider to refine this ratio.
Avoid correction doses if your blood glucose is below 150 mg/dL within 3-4 hours of a previous rapid-acting insulin dose, unless specifically instructed by your healthcare provider.
Insulin stacking (active insulin overlap) can cause hypoglycemia. This calculator doesn't account for insulin-on-board. Consider using continuous glucose monitors or insulin pumps that track active insulin.
This calculator uses established medical formulas developed through decades of diabetes research. The Rule of 1700 and Rule of 450 are widely accepted methods for estimating insulin sensitivity and carbohydrate ratios.
The calculator includes safety assessments for extreme glucose values and provides warnings for potentially dangerous situations. However, it cannot replace clinical judgment and professional medical supervision.
CRITICAL MEDICAL DISCLAIMER: This calculator is for educational purposes only. Insulin dosing errors can be life-threatening. Always consult healthcare professionals and never adjust insulin doses without medical supervision.
Insulin therapy is a cornerstone of diabetes management, requiring precise calculations to balance blood glucose control with hypoglycemia prevention. Understanding insulin pharmacokinetics, carbohydrate counting, and individual sensitivity factors is essential for safe and effective diabetes management across Type 1, Type 2, and gestational diabetes populations.
Insulin dosing calculations are based on well-established clinical formulas validated through decades of diabetes care research. These methods incorporate physiological principles of glucose metabolism, insulin pharmacokinetics, and individual patient factors to provide safe starting points for therapy.
