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

  • 1000000 → 2320000000 = multiply by 2320.00 (or + 231900.00 %) in 14 year(s)
  • multiply by 1.01 (or + 1.07 %) in 1 week
  • multiply by 1.05 (or + 4.72 %) in 1 month
  • multiply by 1.74 (or + 74 %) in 1 year
  • multiply by 254.24 (or + 25324 %) in 1 decade
  • goes x 2 every 1.25 year(s)
  • goes x 5 every 2.91 year(s)
  • goes x 10 every 4.16 year(s)
  • goes x 100 every 8.32 year(s)
