Insulin Dose (Correction) Calculator

Work out insulin dose (correction) instantly with clear inputs, formula shown and shareable results.

About Insulin Dose (Correction) Calculator

Divides the amount by which glucose exceeds target by the insulin sensitivity factor to give a correction dose.

Formula

Correction dose

Units = (current glucose - target glucose) / insulin sensitivity factor

Worked example

With the default values below, Insulin Dose (Correction) Calculator returns Correction dose of 2.50. Change any input above and every figure here is recalculated in your browser.

Inputs used

Current blood glucoseaccepts 40–800 mg/dL
220 mg/dL
Target blood glucoseaccepts 70–250 mg/dL
120 mg/dL
Insulin sensitivity factoraccepts 5–200 mg/dL per unit
40 mg/dL per unit

Results

Correction dose
2.50 units
Rounded to the nearest half unit
2.5 units
Glucose above target
100 mg/dL

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What if glucose is below target?

The correction is zero or negative; a negative result means carbohydrate rather than insulin is needed.

Does this include food?

No. This is the correction component only; mealtime carbohydrate cover is calculated separately.
