2 Total Daily Dose (TDD)
Select a profile factor. This multiplier determines your total daily insulin needs based on physiology.

3 Calculate Basal Rate
Standard starting methodology assumes a 50/50 split. 50% of the TDD is for background (Basal) insulin, and 50% is for food (Bolus).

Ghost Lows
If Basal is set too low, your meal bolus will try to "fill the hole" of the missing basal. This makes carb ratios look wrong.
Testing is Mandatory
This math only provides a starting line. You must perform basal testing (fasting periods) to verify if blood sugar holds steady.
Insulin-To-Carb Ratio Tool
Calculates a baseline Insulin-to-Carb Ratio using the "500 Rule." Input Total Daily Insulin (Basal + Bolus) to get an estimate of how many grams of carbohydrates are covered by a single unit of insulin.
You can use the built-in Reality Check feature to simulate a meal dose.
Determining Total Daily Dose (TDD) is usually done by taking an average rather than looking at a single day, as insulin needs fluctuate based on activity, food, and stress - Learn More

Weight
Medical insulin calculations are standardized in kilograms. We divide lbs by 2.2 to get the metric weight.

Total Daily Dose (TDD)
TDD = Weight (kg) × Factor. This predicts the total amount of insulin (both Basal and Food) your body needs in a 24-hour period.
Select a profile factor. This multiplier determines your total daily insulin needs based on physiology.
Who fits where?
- High Sensitivity: Athletes, Active Kids, Lean T1Ds.
- Standard: Most adults, pre-teen children.
- Resistant: Sedentary adults, illness, high stress.
- Highly Resistant: Puberty (Teens), steroids, growth hormones.

Calculate Basal Rate
Starting Basal is 50% of the Total Daily Dose. This covers your background needs, while the other 50% is reserved for food boluses.
Standard starting methodology assumes a 50/50 split. 50% of the TDD is for background (Basal) insulin, and 50% is for food (Bolus).
