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 day(s)
  • multiply by 1.95 (or + 95 %) in 1 week
  • multiply by 18.16 (or + 1716 %) in 1 month
  • goes x 2 every 1.04 week(s)
  • goes x 5 every 2.41 week(s)
  • goes x 10 every 3.45 week(s)
  • goes x 100 every 1.59 month(s)
