Insulin Dosage Calculator
Calculate your mealtime and correction insulin dose based on current blood glucose, carbohydrates, insulin-to-carb ratio, and correction factor. Always consult your healthcare provider.
Step 1: Blood Glucose & Carbs
Carb counting tips
Be as accurate as possible with carb intake. Use food scales, nutrition labels, or standard exchange lists. When in doubt, consult a dietitian.
Step 2: Insulin Parameters
About correction & meal bolus
Meal dose = carbs ÷ insulin-to-carb ratio. Correction dose = (current BG – target BG) ÷ correction factor (only if BG > target). Total dose = meal + correction.

Correction & Meal Contribution
Dosing Formula
Insulin Dose = (Carbs / ICR) + ( (Current BG – Target BG) / CF )
If current BG is below target, correction dose is usually skipped or reduced – consult your diabetes team. This calculator assumes you only correct when BG > target.
