What This Calculator Does

Calculate tax savings from Health Savings Account contributions.

It combines Annual HSA Contribution, Coverage Type, Federal Tax Rate, State Tax Rate to estimate Annual Tax Savings, Federal Tax Savings, State Tax Savings.

Formula & Method

Core equations: Annual tax savings from HSA contributions: S = C \times (r_{fed} + r_{state} + r_{FICA}) where C is the annual contribution and r_{FICA} = 7.65\%. Amounts above medical expenses grow tax-free, and tax-free growth savings equal: S_{growth} = G \times (r_{fed} + r_{state}) where G is total investment growth. Inputs are applied in base units, then derived metrics are computed from the same equations and rounded for display.

Notation used in the formulas: R = Annual Tax Savings; x_{1} = Annual HSA Contribution; x_{2} = Coverage Type; x_{3} = Federal Tax Rate; x_{4} = State Tax Rate; x_{5} = Annual Medical Expenses; x_{6} = Investment Return (if investing).

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
