Gross to net

A calculator that models a real paycheck under three tax regimes.

Interactive

A calculator that steps through gross pay to net pay for a given salary, filing status, state, and set of pre-tax deductions. The Scholar can adjust 401(k) percentage, HSA contribution, and insurance premiums to see the effect on net pay and on annual tax.

Parameters

  • Annual salary and pay frequency.
  • Filing status and state.
  • 401(k) contribution percentage (traditional vs. Roth).
  • HSA and FSA contributions.
  • Health, dental, vision, and life-insurance premiums.

Expected

The Scholar should end with a per-pay-period net-pay number that matches their own stub within a dollar, and a written note on which pre-tax lever produced the largest effect on take-home while advancing a long-term goal.

Interactive

A working model the Scholar operates to build intuition.
