What does contributing actually cost you?
A traditional contribution comes out before federal income tax, so the money leaving your paycheck is smaller than the money reaching your 401(k). This runs both paychecks through the same 2026 engine and reports the difference, rather than assuming a marginal rate.

to put $196.15 into retirement every check
A traditional contribution comes out before federal income tax, so $196.15 of savings costs you $142.40. It is still Social Security and Medicare wages, which is why it never costs nothing.
Both paychecks are run through the same deterministic 2026 engine and the difference is the cost — no marginal rate is assumed. New York state rules are applied; local taxes remain excluded. Investment growth is not projected.
