How big can this business actually get?
Every business has a mathematical ceiling. Most owners have never calculated theirs.

What the ceiling means
A business signing new customers every month while sitting above its ceiling is shrinking while it feels successful. This is the calculation that surfaces it.
Customer ceiling
New customers ÷ churn. The number of active customers where arrivals exactly equal departures — you stop growing here.
Revenue ceiling
Customer ceiling × price. The same figure also equals new customers × LTV — if the two disagree, a rate has been mixed up.
Below 50%
Plenty of headroom. Volume is the job — more spend converts into real growth, so scale acquisition.
50–80%
Growth is already slowing even if it doesn’t feel like it. Start work on churn and price now, before the plateau arrives.
Above 80%
You are at the plateau. More spend will not stick — the ceiling itself has to move via churn or price.
Above the ceiling
Rare but serious: more customers are leaving than arriving. The business is shrinking despite new customers coming in.
