The FSA Tax Savings Calculator is a free, embeddable calculator from CalcFunnel. See how much a pre-tax Flexible Spending Account contribution saves you in taxes.

You enter 4 inputs: FSA type, annual FSA contribution, marginal tax rate (%) and FICA rate (%).

It returns total tax savings, income tax saved, FICA tax saved, FSA contribution, net cost of contribution and annual FSA limit.
