Eyelash extensions are sold as a one-time full set, but the real cost is the fills. Because fills repeat every 2–3 weeks, the annual total is far higher than the headline set price - and it climbs fast with denser styles.
The annual math
A typical year is one full set plus fills covering the remaining weeks. With 3-week fills that is about 17 appointments. Classic at a $200 set and ~16 fills near $67 each lands around $1,500–$2,500 a year once you add tip; volume runs $2,500–$4,000+ (Pro Lash annual breakdown, ~2026).
By type
Classic is the lowest-cost look, followed by hybrid, then volume, with mega volume the priciest. 2026 set prices run roughly $200 (classic), $275 (hybrid), $325 (volume) and $400 (mega), with fills scaling the same way (Lash Affair, Sense Lashes, ~2026).
How fill frequency changes the number
Stretching fills from every 2 weeks to every 3 can cut a third off your annual bill, but going too long means a near-empty set and sometimes a new full set. The calculator lets you try your real interval and see the yearly difference instantly.
The cheaper comparison
Against a lash lift at about $800–$1,000 a year, even classic extensions cost noticeably more. If budget is the deciding factor, run both routes through the lash lift vs extensions calculator before you book.
