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

  • 1000 → 1000000 = multiply by 1000.00 (or + 99900.00 %) in 20 year(s)
  • multiply by 1.03 (or + 2.92 %) in 1 month
  • multiply by 1.41 (or + 41.25 %) in 1 year
  • multiply by 31.68 (or + 3068 %) in 1 decade
  • goes x 2 every 2.01 year(s)
  • goes x 5 every 4.66 year(s)
  • goes x 10 every 6.67 year(s)
  • goes x 100 every 1.33 decade(s)
