Bolus (~50%, split across meals) 18 units
Total Daily Insulin Requirement Calculator is a health and wellness calculator that helps you calculate total daily insulin requirement values from your input data. The formula used is: TDD = weight (kg) × factor (units/kg); split 50% basal / 50% bolus. Enter values using the units shown next to each input field (e.g. kg, cm, years).
Rates and fees change frequently. Always confirm the current figures
with the official authority before relying on this result.
- Starting estimate only. Insulin initiation and titration must be supervised by a clinician.
Formula
TDD = weight (kg) × factor (units/kg); split 50% basal / 50% bolus
- Total Daily Insulin Requirement Calculator gives you a fast estimate using your inputs and updates instantly when you change any value.
- Formula: TDD = weight (kg) × factor (units/kg); split 50% basal / 50% bolus
- Input definitions: • Body weight: the numeric body weight used in the calculation
- Enter values using the units shown next to each input field (e.g. kg, cm, years).
- This calculator uses widely accepted health formulas and returns screening estimates only. It does not replace a diagnosis from a qualified healthcare professional.
- Compare your result with published reference ranges. Values outside the normal range warrant a conversation with your doctor.
- Practical tip: test a low, medium, and high scenario to understand sensitivity before making decisions.
Example Calculation
Inputs
- Body weight: 70 kg
Suppose you enter: Body weight = 70. The calculator applies the formula (TDD = weight (kg) × factor (units/kg); split 50% basal / 50% bolus) and shows all output values below. Change any input field to immediately see how the result changes.

Basal Insulin Dose Calculator Estimate a starting basal (background) insulin dose from body weight. A common rule of thumb sets the total daily insulin dose (TDD) at around 0.3–0.7 units per kilogram, with roughly half of that given as long-acting basal insulin. Enter weight and a dose factor to see an estimated basal dose, TDD, and the amount left for mealtime bolus insulin. Mealtime Insulin Dose Calculator Mealtime Insulin Dose Calculator is a health and wellness calculator that helps you calculate mealtime insulin dose values from your input data. The formula used is: Total = (carbs ÷ carb ratio) + max(0, (current − target) ÷ ISF). Enter values using the units shown next to each input field (e.g. kg, cm, years). Insulin Sensitivity Factor Calculator Insulin Sensitivity Factor Calculator is a health and wellness calculator that helps you calculate insulin sensitivity factor values from your input data. The formula used is: ISF (mg/dL) = 1800 ÷ total daily dose (rapid-acting) or 1500 ÷ TDD (regular). Enter values using the units shown next to each input field (e.g. kg, cm, years).
