Salons quote lashes per service, but the number most people really want is the monthly hit to their budget. Because fills come every two to three weeks, the monthly figure is higher than a single fill price suggests.
The monthly math
Take your full annual cost - full set, all your fills, tips, the odd removal and aftercare - and divide by twelve. A typical hybrid set on 3-week fills works out to roughly $156 a month. Classic runs lower, around $100–$165 a month, and mega volume can top $300.
Why it is more than one fill
At a fill every three weeks you are booking about 1.5 visits a month, plus a tip each time and aftercare products through the year. A single $80 fill looks affordable in isolation, but the cadence is what turns lashes into a recurring monthly subscription.
Lowering the monthly cost
Stretching fills to every three or four weeks, tipping on the service rather than padding it, and protecting your lashes with proper aftercare all trim the monthly total. The biggest lever, though, is switching some or all of the year to a DIY cluster kit and serum, which can cut the monthly cost to around $50.
