Exponential growth calculator

Some things grow or decay in an exponential way. This means that for every time unit (e.g. a day) the metric changes with ± the same percentage.
If you can say "it doubles every _ days" => this means it has exponential growth/increase!
If you can say "it drops to half every _ days", it has logarithmic decay/decrease!

Growth calculation

Exponential factor

  • 100 → 110 = multiply by 1.10 (or + 10.00 %) in 1 month(s)
  • multiply by 1.02 (or + 2.22 %) in 1 week
  • multiply by 3.14 (or + 214 %) in 1 year
  • multiply by 93291.90 (or + 9329090 %) in 1 decade
  • goes x 2 every 7.27 month(s)
  • goes x 5 every 1.41 year(s)
  • goes x 10 every 2.01 year(s)
  • goes x 100 every 4.03 year(s)
