FSA Calculator (2026)

An FSA is employer-owned, typically requires use-it-or-lose-it within the plan year, and works with standard health plans. An HSA is personally owned, rolls over indefinitely, and requires enrollment in a high-deductible health plan (HDHP).

FSA funds generally must be spent on qualified expenses incurred during the plan year. Any unspent balance remaining after the employer deadline is forfeited to the plan administrator.

The projected 2026 Healthcare FSA employee contribution limit is approximately $3,300 per employee, exempt from federal income, Social Security, and Medicare taxes.

Employers may offer either a 2.5-month grace period to spend remaining funds or a rollover option allowing up to approximately $660 of unused funds into the next plan year.

Eligible expenses include copays, doctor visits, prescription medications, prescription eyeglasses, contact lenses, dental cleaning, orthodontics, and over-the-counter health items.
