The calculator goes through several steps to calculate the amount of time and money lost due to migraine:

1. Based on your input of your company’s size, type of industry, location, and the age/gender breakdown, the model estimates the prevalence of migraine in your company.
    
2. Using an estimate of 8 days per year lost due to migraine and total compensation for employees in your company (wages + benefits), the model graphically presents annualized estimates of lost workday equivalents due to migraine. Please see Estimating the number of days lost for an explanation of why 8 days per year was selected as a baseline.
    
3. Prior to performing any calculations, the employee workforce is divided into diagnosed (48%) and undiagnosed (52%) groups. The main module then examines the impact of treatment on 85% of the diagnosed group and 65% of the undiagnosed group. See Characterizing the migraine population for a more detailed explanation of why these numbers were chosen.
    
4. Because some of the population will already be taking and benefiting from triptans (10%), costs are displayed separately for those who are already benefiting from therapy (the currently on triptan group) and those who are not on triptans but will benefit from taking them (the not currently on triptan therapy group). The numbers for these groups will be summed together to present a net benefit figure for triptan treatment.
    
5. The cumulative treatment benefits for 3 years will then be presented.

You may use your own values for each of the estimates described above, but the default values provided are based on published research studies and are representative of all migraineurs.
