Storage Growth
Enter used and total capacity and the growth rate (TB/month or %/month) and I compute when you hit the alert threshold and 100%, with the month-by-month projection.

How it is computed · linear vs. compound
Linear. Usage grows a fixed amount of
TB each month. Months to a target:
months = (target − used) / rate.
Compound. Usage grows a percentage
r over the previous level:
used × (1 + r)ⁿ = target, so
n = ln(target / used) / ln(1 + r).
Threshold. The threshold target is
target = total × threshold / 100. 100% is simply the
total.
Projection. Capacity at N months:
linear used + rate × N; compound
used × (1 + r)ᴺ.
! This is an estimate that assumes a steady rate. Real growth varies with retention, compression, deduplication and project spikes. Plan the expansion before hitting the threshold, not at 100%.
