To calculate carb coverage, divide the total carbs you’re consuming by your insulin-to-carb ratio. This will give you the amount of insulin needed to cover the carbs.
Carb coverage refers to calculating the correct amount of insulin that is required to cover the carbohydrates in a meal. Notably, for those managing diabetes, especially type 1, finding the right insulin-to-carb ratio is crucial.
By using this carb coverage calculator, you can accurately calculate how much insulin you need to balance your carb intake and maintain optimal blood glucose levels.
Formula:
I = C / R
Symbol | Description |

I | Insulin Needed |
C | Total Carbs Consumed (grams) |
R | Insulin-to-Carb Ratio |
Solved Calculation:
Example 1:
Scenario: You plan to eat 45 grams of carbs, and your insulin-to-carb ratio is 1:15.
Step | Calculation |
---|---|
Divide Carbs by Insulin-to-Carb Ratio | 45 / 15 = 3 units |
Answer: You need 3 units of insulin.
Example 2:
Scenario: You plan to consume 60 grams of carbs, and your insulin-to-carb ratio is 1:10.
Step | Calculation |
---|---|
Divide Carbs by Insulin-to-Carb Ratio | 60 / 10 = 6 units |
Answer: You need 6 units of insulin.
