Published estimates run from $78.5 billion to $4 trillion — a fifty-fold spread for the same country. Almost none of that gap is disagreement about the epidemic. It comes down to three choices, and on this page you make them yourself.
Set the controls to any published study's choices and the total reproduces that study's headline. That is how you can tell this explanation is the real one rather than a guess.
Where your total sits against the four published estimates. The spacing is logarithmic — each equal step is a tenfold increase — because a linear axis would put the first two studies on top of each other.
Click any row to load that study's settings into the controls above. Hover for the arithmetic.
