# 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!

### 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 1.10 (or + 10 %) in 1 month
• multiply by 3.14 (or + 214 %) in 1 year
• multiply by 93291.90 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)
