Insulin Dosage Calculator

Insulin Dosage Calculator for Endocrinology. The remaining bolus quantity is not a per-meal instruction. Active insulin, food intake, exercise and glucose trends can change actual dosing decisions. The displayed decimal precision is for arithmetic checking, not an instruction to deliver an unsupported device increment.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

Total daily insulin = weight in kg x prescribed units/kg/day. Basal quantity = total x prescribed basal percentage / 100; the remainder is the total daily bolus quantity. The coefficient is not an insulin sensitivity or glucose correction factor, and the basal share is not fixed automatically.

When to use this calculator

Use only as an arithmetic cross-check of parameters already chosen by the treating team. ADA 2026 describes individualized insulin management; this tool does not select an initial regimen, account for glucose patterns or decide whether insulin is indicated.

Inputs used

  • Weight in kg or lb
  • Already prescribed daily coefficient in units/kg/day
  • Already prescribed basal share in percent

Clinical interpretation

The remaining bolus quantity is not a per-meal instruction. Active insulin, food intake, exercise and glucose trends can change actual dosing decisions. The displayed decimal precision is for arithmetic checking, not an instruction to deliver an unsupported device increment.

Worked example

For 80 kg, an illustrative prescribed coefficient of 0.5 units/kg/day and basal share of 40%, the total is 40 units/day: 16 basal and 24 remaining daily bolus units. A 100% basal share leaves zero remaining bolus quantity. These examples are not starting-dose recommendations.

Limitations and safety notes

No preset population coefficients, equal-meal split, correction dose or titration schedule are supplied. Renal function, hypoglycemia, pregnancy, illness, formulation and delivery device are not modeled. Input maxima are software bounds, not recommended doses or ceilings. Independent prescription verification remains necessary.

Frequently asked questions

Is the entered coefficient a correction factor?

No. It has units/kg/day dimensions. A glucose correction factor describes expected glucose change per insulin unit.

Should I divide the bolus remainder equally across meals?

The tool does not make that recommendation. Meal dosing requires the prescribed plan and relevant glucose, carbohydrate and active-insulin information.
