HIT-6 Calculator

Score your headache impact over the last 4 weeks. Validated, used by neurologists, and required by most insurers for CGRP inhibitor and Botox approvals.

Choose one answer per question. Each answer is worth 6, 8, 10, 11, or 13 points. Reference period: the last 4 weeks.

1. When you have headaches, how often is the pain severe?

How the score is graded

Score Impact Meaning

50–55SomeNoticeable but mostly manageable
56–59SubstantialInterfering with significant parts of life
60–78SevereDominating your daily experience

The watch-line is 56. Below that, most clinicians manage with abortive medication only. At or above, the conversation usually shifts to preventives. A score of 60+ is the standard threshold for CGRP inhibitor and Botox approval in most US insurance systems.

For the full background on what HIT-6 measures and how to use it clinically, read our guide to the HIT-6 test. Your neurologist will likely also want to see your MIDAS score — they're complementary (HIT-6 = intensity, MIDAS = volume).

Auto-track your HIT-6 over time

HIT-6 measures the last 4 weeks, so it shifts. Tracking the trend matters more than any single score. Migra auto-calculates your HIT-6 from logged attacks and shows the trend over time, so you can see whether a new preventive is actually working.
