Questions about the healthcare flexible spending account tax savings calculator
How does a healthcare FSA save money?
You fund it with pre-tax dollars, so you avoid both income tax and FICA on the amount — effectively a discount equal to your tax rate on eligible medical expenses.
What is the FSA contribution limit?
It is set annually by the IRS (around $3,200 in recent years). Contributions are deducted from your paycheck before taxes throughout the year.
What is the "use-it-or-lose-it" rule?
FSA funds generally must be spent within the plan year; unused money is forfeited, though plans may offer a small carryover or short grace period. Estimate your spending carefully.
