Exponential growth
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)
