Fill cycle chair capacity planner
Work out how many hours of your week your existing lash clients already own at your fill interval, and how much room is genuinely left for new sets.
A lash book fills itself in a way most trades never experience. Every client you keep at a three week interval comes back roughly 17 times a year, so a healthy retained list becomes a standing claim on your calendar long before you notice. That is exactly what you want, until the day you take a new full set booking and discover there is nowhere to put next week's fills.
This planner does that arithmetic. Enter your active client count, the interval you actually hold, and the hours your bed is genuinely bookable. It returns the number of fills each week, the chair hours they consume, and how many new full sets you can still accept before the cycle starts colliding with itself.
Your result
Fills your list creates each week
15.0
Fill appointments your current clients generate weekly if every one of them holds the interval.
Chair hours those fills take
22.5
Hours committed to existing clients before you book a single new set.
Bookable hours in your week
28.0
Total hours the bed can hold a client in a normal working week.
New full sets you can still take
2
Full sets that fit in the hours left once your fill cycle is seated.
If this shows zero new sets, your bed is at capacity on fills alone, which is the moment to raise your rate rather than chase new clients.
Why a shorter interval needs fewer clients, not more
Push the interval field from three weeks to five and watch the fills per week drop. That is the trap in a stretched cycle: it makes your calendar look roomy, so you go looking for new clients to fill the gaps, and the new clients arrive as full sets that eat two and a half hours each instead of fills that take ninety minutes.
Run it the other way and the picture is clearer. At three weeks, a list of 45 clients keeps the bed busy on fills alone. At five weeks the same list leaves holes you will spend money on marketing to plug, while the clients you already have quietly turn into rescue sets. The client count you need is a function of the interval you hold.
Reading the result before you open your books to new clients
When the new sets figure sits at one or two a week, you are in the healthy zone: enough new work to replace natural attrition, not so much that a full set week wrecks your fill spacing. When it hits zero, taking on more clients means somebody's fill gets pushed, and a pushed fill at week four turns into a longer appointment you did not price for.
That is the moment to raise your rate, tighten your cancellation terms or add a second bed, in that order. Most artists do it backwards and add hours to the day, which raises revenue for a season and then costs you the shoulders and eyes this work depends on.
Questions about this calculator
What counts as an active lash client?
Someone who has sat in your chair for a fill within roughly the last two months and has not told you she is stopping. Clients who last came in six months ago are not part of your capacity, they are a reactivation list and belong in a different calculation.
My interval is different for different clients. What do I enter?
Enter the average you actually hold rather than the one you would like. If your fast shedders sit at two weeks and everyone else at three and a half, an average around three is honest. The planner is about total load on the bed, not about any single client.
Should removals and lash lifts go in this calculation?
Only if they take a meaningful share of your week. If you do a few lifts and tints, treat them like new sets and reduce your available hours a little. If lifts are a large part of your menu, run the planner twice, once for the extension side and once for everything else.

The fill cycle client record template
One page per lash client that turns guesswork about her rebook date into a record you can read before she sits down.
Now hold that fill interval in a real week
The figure above assumes every lash client comes back on the spacing you entered. Holding that with forty clients and a shed cycle that ignores your policy is the actual work. LashRetention scores each client on what stayed attached, sets her due date from her own pattern, and prompts the rebook before she is off the bed.
