Coronavirus Spread Calculator

Coronavirus Calculator: Calculate Rate of Potential Spread in Your City/Country

I’ve created this Coronavirus calculator to illustrate how fast the Coronavirus spreads if you do not implement extreme measures very quickly. You will see that 1 infection today, even at the low growth rate, turns into 1 million by mid-August.

To see the how fast the virus spreads, simply enter the current # of Coronavirus cases in your area today to see how many potential infections will exist in the coming days, weeks, and months. (Parentheses represent hospitalization and mortality rates.)

Enter the current number of active Coronavirus cases above to populate this table.

  • Low growth rate: The Coronavirus doubles every 7 days.
  • Medium growth rate: The Coronavirus doubles every 5 days.
  • High growth rate: The Coronavirus doubles every 3 days.
  • Hospitalization and mortality rates are based on the latest data of 10% and 1% respectively.
