Calculator
Lash set cost and price floor calculator
Find the true cost of one set at your own bed, including the overhead every appointment quietly carries and the cut your card reader takes.

Free calculators for lash and brow artists
Two working calculators for the numbers that decide whether a lash studio pays for itself: what a set costs you, and what your bed can actually carry.
Lash pricing gets set by looking at what the artist down the road charges, and lash schedules get set by hope. Both deserve arithmetic. The first calculator takes product, chair time, studio overhead and the card fee and returns the price floor a full set has to clear before you are working for free. The second takes your active client count and your fill interval and shows how many hours of your week those fills already own.
Nothing is stored and nothing is emailed. Change the inputs, read the numbers, write them on the back of your service menu. If the second calculator tells you the bed is already full of fills at three weeks, that is not a problem to fix, it is the healthiest thing a lash book can show you, and it is the argument for raising your rate rather than chasing new clients.
Calculator
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.
Working document
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.
Why the lash calculators ask nothing of you
Every lash artist already does this arithmetic, usually on the back of a receipt while the adhesive cures on somebody's inner corner. You add up the tray, the adhesive, the primer, the pads and the tape, guess at the chair hours, leave the booth rent out entirely, and land on a full set price that felt about right two years ago. The schedule gets the same treatment: forty odd clients, a three week interval, and a feeling that the bed is busy enough. Both of those are short sums with known inputs, so there is no honest reason to put an email form in front of them.
So there is no sign up, no account and nothing stored when you close the tab. Run them between a fill and a full set and write the two figures inside the cover of your appointment book: the floor a set has to clear once the processor takes its percentage, and the chair hours your existing fill cycle already owns every week. Those two numbers will settle most menu and scheduling arguments on their own, whether or not you ever open LashRetention. If the capacity planner tells you fills alone seat the bed at three weeks, you have your pricing answer before anyone tries to sell you software.
From a calculator to a live lash book
A price floor and a weekly fill load only matter if something holds them in place. LashRetention keeps the interval behind those figures honest client by client, so the fills per week number describes what your bed actually does rather than what it could do.
