How do I calculate my Total Daily Insulin (TDI)?

Total Daily Insulin includes both basal and bolus insulin. If you don’t know your Total Daily Insulin, speak with your healthcare provider to get this value.

If you are already using a Tandem insulin pump, you can find your Total Daily Insulin in your Pump History. To get a good estimate of your average total daily insulin, you should select at least the 14-day average.
