How this is calculated
Equity is annualised by dividing the total grant by four, the standard vesting period. It assumes the grant is worth its stated value, which for private companies it may not be.
Bonus is calculated at target, not maximum. Ask what was actually paid out last year before you count on it.
Cost of living rebases both offers to a US national average of 100. Major hubs like London or New York tend to sit around 120–135; much of continental Europe sits lower.
Tax is deliberately excluded — rates vary too much by country and personal circumstance to model usefully here.
The gap
$26,057 / yr
Offer B is worth about 14% more once bonus, equity and cost of living are accounted for.
